I think this course gives a chance to anyone who wants to learn machine learning in a fast and free way. And save a bunch of time looking at papers and library literature. This course is gradual. There is a clear understanding of everything from linear regression to reinforcement learning, and even the example programs are fully described and annotated. The people who made and designed this course are very thoughtful and selfless sharing and deserve huge applause. Thank you very much.

Hey just to confirm, are you sure the 1:00:00 is the linear regression and not linear classification. i am not able to get this. we are classifying whether it will be survived or not. based on the input data. can some one please help with this
1:19:30 In case anyone is curious, in the Titanic Dataset, "parch" is "Parents/Children" (ie: was this person travelling with other family members), and "fare" is the price paid for their ticket (which may include travelling costs for other people they were travelling with, family or not).
CAUTION: The Vido is outdated, you can use the video for concepts but code wise TensorFlow has deprecated many modules that are used in the code he mentioned.
@@EJYIEI hey im at that point where I want to use keras models instead of estimators but I cant figure out the tutorial for a linearregression model any chance you could share your code for that section?
Just a comment, on 3:36:44, when you train the network again it's not re-training from scratch but instead using the weights it already had. Unless you manually reset the graph, you'll be training for the sum of all epochs you used the fit function (like 10 + 8 + 1 epochs) To avoid this problem you should use something like keras.backend.clear_session() or tf.reset_default_graph() between tests with hyperparameters 😉
*My takeaways:* 1. TensorFlow has two main components: graph and session 33:05 2. We can rebuild a model and change its original parameters 5:56:31 3. Reinforcement learning with Q-Learning 6:08:00
This video is gold. I am a MSc student in AI and I literally use this video as a reference to understand some topics that are poorly explained in the modules. I've watched 5/7 hours
For people wanting to understand the basic idea behind Neural Networks, 3BlueOneBrown's video is a nice addition to your introduction! It helped me understand the topics and coding Tim discussed a lot better
parch: The dataset defines family relations in this way... Parent = mother, father Child = daughter, son, stepdaughter, stepson Some children travelled only with a nanny, therefore parch=0 for them.
Hello Sir.. I need a program, vba, excel sheet, or anything else.. In which I do add may data in Numaric form that is 1,2,3 etc and then that data plot or draw in AutoCAD with one click
Run time 3:37:00 - I think we have to compile the model every time before we do a fit. Otherwise it just memorize the previous epochs and use it for next iterations. In this case I believe that 92% accuracy of 1 epochs is the same as the addition of previous epochs i.e 10+8+1 = 19 epochs
Well im not the best at python.. But its my favorite out of all the language i know. So whenever i dont understand something i be like chill its just python. That helps at least to some extend.
I typically hate narrative talk alongside & prefer scripted tutorials, but you’ve spoken very clearly & concisely while extemporaneously. Very well done! 🙏🏼
very good course tim . I am 12 and have finished ur course upto neural networks ur a great teacher , ignore the bad comments cause the people who post these comments are failures that are jealous of u , so never ever give up !!
Despite being lost in the RNN part haha, this tutorial was great! I really appreciate your hard work and you've done great in simplifying explanations. Well done! It's programmers like yourself that make it possible for anybody to learn programming and that is a great thing. I hope to see more courses from you in the future!
At 3:37:00, when you said with less epochs, you are getting better test results. Which is actually not the case. You first run for 10 epochs, your weights got updated. Then again you run 8 epochs, your weights improved from previous values onwards.. so that eventually makes 18 epochs.. then you run for 1 epoch, which makes it 19 epochs.. so in this case, after 19th epoch, your accuracy on test data is increased.
Just wanted to add one small detail that in Module 4, while training the model on 1 epoch after training it for sometime, what actually happens in ipython notebooks is that they continue training on above of the previously trained model. So, that is why we got pretty high accuracy for one epoch, but technically that accuracy we got was not just from one epoch.
@@lawrencegranda7759 I was watching this and even though I am totally newbie I also noticed that the training was simply continuing, not starting from scratch.
ok when he said at the start im going to explain everything I didn't believe. he literally explained everything used. like even summation, SD etc., real pro. damn I'm never gonna get good like this guy.
I've been going back and forth between python to game development... but I haven't actually learned anything and now I'm here for machine learning, and before this I started hacking course. Everything unfinished, and just the thought of what I would be able to do when I get good at either of these is what makes me want to learn them, but I can't really stick to one.
Happens with everyone . I went with flask to build a website , then api , left it , did a but of numpy , now here . Im just looking to find something that interests me enough to make me stick to it for a longer time, you should keep looking for something that might interest you so that you stick with it longer !
@@abhinavyadav789 The thing I really want to do, is what I don't have support with of any kind. So, it's like, I'm just trying to find something, in places where I know I won't find it.
Just finished the tutorial, it's really well made and an amazing intro to ML concepts. I'm really excited to explore this further thankyou so much Tim.

I only watched until 20 minutes today, but I can say this really helped me get a theortical grasp on machine learning in general. I just though machine learning is just predicting data but today i learned that in order for it to do that it uses an algorithm that make rules than follows them and gives back the label (output) thank you sm!!
Parch represents number of parents and/or children passengers onboard the ship with (1:17:49) Fare represents the fare price. The ticket price (1:18:05)
1:19:41 someone else has to have made a comment about this but fare refers to the price you paid for a ticket. As in the amount they paid to board the ship for the voyage. It’s a general term that broadly speaking means amount that you contributed economically to partake in or embark on an activity. You could feasibly replace fare with “price of ticket” or “entrance fee” and it would mean the same thing. Fare has a slightly different connotation but in any practical way it’s a synonym for cost of a thing. It’s notably not a tensor flow specific term.
Thanks, man, I was having difficulties learning core concepts of ML for a long time but this video cleared all my queries and now I understand everything which you've explained. Thanks again for making this video. It helped a lot
Tim, I know you've heard this before, but this was a very well done course on Tensorflow basics and Machine Learning. This is my first online course I've taken and glad it was yours! Thanks for the time you put into this course which will help countless programmers and adventurers interested in this fascinating field.
The second argument to tf.Variable() is trainable not dtype, so when you set string = tf.Variable('some string', tf.string), you set string.trainable to tf.string. You can verify it by printing string.trainable.
Classical programming : Answers=f(Data, Rules) Machine learning : Rules = f(Data, Answers) That cleared all my questions on difference between classical programming and machine learning . Thanks for that 😇😇
Mate, this was very cool. I'd never heard of it before, but coming from a Python background, I found this very helpful. Keep up the great work! Looking forward to what else you have on offer.
You should NOT expect us to "look up" some of these parameters, instead you should explain them, if not, then please give reference of where we should look them up. I'm referring to the video position that ended around 3.31. once you started explaining the math, I started to understand. but I know your viewers are not 2nd year calculus. but so far, this is the best video out there that explains Tensor flow.
It's 2022 and this video is as relevant as ever. I didn't really follow up in the latter parts but you really did a good job explaining stuff. Thanks!!!
I've been in this course for over 2 hours. I think this is a good point to start with as it can equip beginners with a big picture, together with quick (but enough) explanations on the terms such as ML, layer, etc. Although some of the codes provided in the GG collab couldn't run properly in 2024 (right now), I suggest watching the video to have a grasp on what might happen and practice them later (maybe in another course, or if you can figure out somehow to execute these codes). Happy learning!
This is aweome. I paid for a course online - but could not understand lots of things .. just was able to clear all confusing concepts in this video. Thanks mate
I just don't know how to thank you ALL YOUR EFFORT on doing that video! All the content and the explanation! It's just mind blowing! I am eternally grateful!
Good work, I appreciate you trying to teach the masses. However, the first example is not linear regression, it is binomial logistic regression and doesn't really represent what you explain earlier in the first part of the video. Perhaps the housing price data set or another data set would be a good example for this, with binomial logistic regression as a second step that then leads into multinomial logistic regression.
This video is a must-watch for beginners getting into machine learning. I wish I had seen this video before. I have never got a better understanding of these topics and the differences between the terms AI, Machine Learning, etc. Thank you, sir, for your efforts. I am in class 12, and there is Linear Regression in Mathematics, but I haven't even thought that it can be used in ML also.
Okay I'm not completely sure about this so take it with a grain of salt but I don't think you're hyperparameter/epoch tuning at 3:37:00 is doing what you expect. With jupyter notebooks, it saves the models and each time you run an epoch, it continues tuning the previous weights. In order to really display epoch differences, you need to restart the runtime and repeat the process. If you notice, each time you run the code, the "first epoch accuracy" increases significantly. The first time you ran it, the accuracy was 83% after the first epoch. After the 10th, it was 90.6%. Then, for the next iteration (8 epochs), the accuracy was 91.2% after the first epoch. Then, when running on just a single epoch, it started at 93%. Likely this is because the model continued to train an additional 9 epochs. So, in fact, the single epoch data is ironically quite overfitting.
For those who stumble upon the error "AttributeError: module 'keras.preprocessing.sequence' has no attribute 'pad_sequences'" at 5:16:32: the pad_sequences function has been moved, you can do it like this now: train_data = keras.utils.pad_sequences(train_data, MAXLEN) test_data = keras.utils.pad_sequences(test_data, MAXLEN)
3:36:25 The accuracy keeps going up is because everytime you execute the codeblock, it takes the trained model and runs it for the specified number of epochs, since .fit() is being called on the same variable 'model'. To start training it with a fresh model, just re-initialize the variable 'model' by executing the code block with 'model = keras.Sequential([...])'.
3:37:01 Training on one epoch in this case builds on already existing model that was created using many epochs. You need to recreate the model to demonstrate this

I was thinking about this, and how tf he could actually get .9x in just one epoch
Loved it! Great tutorial covering a lot of areas. TechWithTim's explanation and the epic examples help open up the field to beginners like me, and the 7 hours were super-interesting!
46:54 A tensor of degree 0 is a scalar, which is a single numerical value. Therefore, the shape of a tensor of degree 0 is an empty tuple, denoted by '()'.
In module 3 at 2:36:20, it's accidentally backwards in the ipynb file. "initial_distribution = tfd.Categorical(probs=[0.2, 0.8])" should be [0.8, 0.2] like in the video. Actually, all the numbers in that code block are mismatched from the video and don't match the weather diagram.
Also "!pip install tensorflow_probability==0.8.0rc0 --user --upgrade" will no longer work, it needs to be "!pip install tensorflow_probability --user --upgrade" and then doing a FACTORY RESET RUNTIME and clicking the reconnect button.
I love being taught by a cute and smart guy... This guy knows his topic has a clear bold voice and talks in a way that is easy to understand (I am not native English, I am from Quebec City)...
This guy is a genius. Everybody can just rattle knowledge off, but he answers all questions aside you subconsciously have the second they come up. I've never met a person understanding the process you go through while learning so good as he does.
Great Video (even if i havent finished it yet)! The example in 1:00:10 is NOT regression is Classification. You have 2 classes (survived or not) and you try to classify the passengers. In other words, the result would always be a probability, you cannot use the same methodology to predict the age, for example .
Alright! This isi the most amazing tutorial I have seen with TensorFlow! I cant believe I can watch a tutorial for almost 7 hours being addicted. Thanks alot!
There are a lot of tutorials like this already available but there is less content about cleaning data or building pipelines it would be really helpful if you could make tutorials on it
Yep, or managing an automated 1D covnet with attention designed for time series prediction. This is both a desired topic at the moment and he could fundamentally demonstrate all the basics of building an automated pipeline where new data comes in, model updates and self optimizes, then outputs a prediction, process repeats upon completion or arrival of new data. This is something me and everyone getting into time series forecasting ML wants to see and it is not too ungodly complex like some other automated ML processes.
@@RoboticusMusic all i am saying is that no one wants to make videos on the complex stuff almost all the content in this video has like 50 similar videos or blogs
@@abcdxx1059Very true. In the financial time series forecasting ML sphere I've only met one guy (Tom Starke) who has said anything rational. Everyone else is more or less Siraj. ML is not inherently bad but the industry is a huge elaborate scam like cryptocurrency. I haven't seen anyone build better ML models than the hand tuned hands-on real time manual adjustment algorithms I've built. I only need ML as icing on the cake to extract any last edge, and nobody seems to understand the basic principles of building a predictive model. For example none of the tutorials explain one-shot methods. That means everything out there overfits and it worse than useless! If a model can't learn in one episode it fundamentally is performing a very expensive database memorization hallucination.
Just finished the entire video, your explanations were great and I got all the examples to work on my local machine, so kudos it was an amazing course :)
Thank you so much! After finishing some high level ai courses i was in search for a hands-on tutorial an this course was exactly the right "depth" i was searching for. Nice to see, that it's not necessary to understand every confusing math formula in depth to get started using ai.
I'm only 35 minutes in but just have to make a comment and let you know I love the way you present this and your communication is great. I appreciate your time making this and I'm very glad you did! Thanks Dawg
Every video I've watched on Machine learning assumes we're in 1st grade and a college math major at the same time. "A tensor is a generalization of multidimensional vectors or matrices blah blah blah" 5 mins later "Slope is rise over run."
It's easier to explain what slope is then what a tensor is. It boggles your mind. Vector already represents multiple dimensions, and tensor is a multidimensional vector? That's pretty much impossible to visualise and get an intuition for. Slopes on the other hand, is rise over run.

I get what you mean, either you end up in some multivariable calculus explanaition or a lame ass "just a weighted sum bro aka Siraj Raval"

And save a bunch of time looking at papers and library literature.
This course is gradual.
There is a clear understanding of everything from linear regression to reinforcement learning, and even the example programs are fully described and annotated. The people who made and designed this course are very thoughtful and selfless sharing and deserve huge applause.
Thank you very much.

Just a comment, on 3:36:44, when you train the network again it's not re-training from scratch but instead using the weights it already had. Unless you manually reset the graph, you'll be training for the sum of all epochs you used the fit function (like 10 + 8 + 1 epochs)
To avoid this problem you should use something like keras.backend.clear_session() or tf.reset_default_graph() between tests with hyperparameters 😉
Mm thought that was the case. Wasn't starting from the ~80% accuracy from the first epoch of the latter training runs.
Another way is just to rebuild the model.
this was painful to watch yeah.. i know he's doing his best to show stuff but he's pretty much a beginner too

Hello Sir..
I need a program, vba, excel sheet, or anything else.. In which I do add may data in Numaric form that is 1,2,3 etc and then that data plot or draw in AutoCAD with one click
@Dario Argies relax pal
Run time 3:37:00 - I think we have to compile the model every time before we do a fit. Otherwise it just memorize the previous epochs and use it for next iterations. In this case I believe that 92% accuracy of 1 epochs is the same as the addition of previous epochs i.e 10+8+1 = 19 epochs
I agree 100%. He was overfitting the model even more.
1:02:44 "Do not Memorize just Understand" - made my mind to stay "calm". Felt to thank at that time frame... "Thank You!"
Well im not the best at python.. But its my favorite out of all the language i know. So whenever i dont understand something i be like chill its just python. That helps at least to some extend.
I thought the same, it gave me a relief.
I typically hate narrative talk alongside & prefer scripted tutorials, but you’ve spoken very clearly & concisely while extemporaneously. Very well done! 🙏🏼
Fare would be the amount they paid for the trip / ticket price. Parch is # of Parents/Children aboard.
Yeah I was thinking that fare was a function of cabin class (base value) and destination (length on board).
very good course tim . I am 12 and have finished ur course upto neural networks ur a great teacher , ignore the bad comments cause the people who post these comments are failures that are jealous of u , so never ever give up !!
Despite being lost in the RNN part haha, this tutorial was great! I really appreciate your hard work and you've done great in simplifying explanations. Well done! It's programmers like yourself that make it possible for anybody to learn programming and that is a great thing. I hope to see more courses from you in the future!
At 3:37:00, when you said with less epochs, you are getting better test results. Which is actually not the case. You first run for 10 epochs, your weights got updated. Then again you run 8 epochs, your weights improved from previous values onwards.. so that eventually makes 18 epochs.. then you run for 1 epoch, which makes it 19 epochs.. so in this case, after 19th epoch, your accuracy on test data is increased.
I was about to write the same thing...seems like I'm not the only one who noticed :)
Wow, Amazing. Eventually I lost the hole to continue in machine learning but you just had gave me a road to run on for a long amount of time!!
Just wanted to add one small detail that in Module 4, while training the model on 1 epoch after training it for sometime, what actually happens in ipython notebooks is that they continue training on above of the previously trained model. So, that is why we got pretty high accuracy for one epoch, but technically that accuracy we got was not just from one epoch.
Are you sure? Adding on one epoch to that model made a significant jump from its previous accuracy. I don't believe this is the case.
I agree. He did not restart/rebuild the model, so it just kept training using the previous weights
@@lawrencegranda7759 I was watching this and even though I am totally newbie I also noticed that the training was simply continuing, not starting from scratch.
ok when he said at the start im going to explain everything I didn't believe. he literally explained everything used. like even summation, SD etc., real pro. damn I'm never gonna get good like this guy.
I've been going back and forth between python to game development... but I haven't actually learned anything and now I'm here for machine learning, and before this I started hacking course.

1:19:41 someone else has to have made a comment about this but fare refers to the price you paid for a ticket. As in the amount they paid to board the ship for the voyage. It’s a general term that broadly speaking means amount that you contributed economically to partake in or embark on an activity. You could feasibly replace fare with “price of ticket” or “entrance fee” and it would mean the same thing. Fare has a slightly different connotation but in any practical way it’s a synonym for cost of a thing. It’s notably not a tensor flow specific term.

You should NOT expect us to "look up" some of these parameters, instead you should explain them, if not, then please give reference of where we should look them up.

I've been in this course for over 2 hours.
I think this is a good point to start with as it can equip beginners with a big picture, together with quick (but enough) explanations on the terms such as ML, layer, etc.
Although some of the codes provided in the GG collab couldn't run properly in 2024 (right now), I suggest watching the video to have a grasp on what might happen and practice them later (maybe in another course, or if you can figure out somehow to execute these codes).

Amazing!!! I did a udemy course but this is a lot better!! Btw anyone here who watched the whole 7 hrs of video on a go or in one day?
Good work, I appreciate you trying to teach the masses. However, the first example is not linear regression, it is binomial logistic regression and doesn't really represent what you explain earlier in the first part of the video. Perhaps the housing price data set or another data set would be a good example for this, with binomial logistic regression as a second step that then leads into multinomial logistic regression.
Only 25 mins and already so good! Your videos never disappoint, Tim!
This video is a must-watch for beginners getting into machine learning. I wish I had seen this video before. I have never got a better understanding of these topics and the differences between the terms AI, Machine Learning, etc. Thank you, sir, for your efforts.
I am in class 12, and there is Linear Regression in Mathematics, but I haven't even thought that it can be used in ML also.
Just curious to know, what are u doing now dude? i mean in programming area
Okay I'm not completely sure about this so take it with a grain of salt but I don't think you're hyperparameter/epoch tuning at 3:37:00 is doing what you expect. With jupyter notebooks, it saves the models and each time you run an epoch, it continues tuning the previous weights. In order to really display epoch differences, you need to restart the runtime and repeat the process. If you notice, each time you run the code, the "first epoch accuracy" increases significantly. The first time you ran it, the accuracy was 83% after the first epoch. After the 10th, it was 90.6%. Then, for the next iteration (8 epochs), the accuracy was 91.2% after the first epoch. Then, when running on just a single epoch, it started at 93%. Likely this is because the model continued to train an additional 9 epochs. So, in fact, the single epoch data is ironically quite overfitting.
This is pure GOLD!!!!
For those who stumble upon the error "AttributeError: module 'keras.preprocessing.sequence' has no attribute 'pad_sequences'" at 5:16:32:
the pad_sequences function has been moved, you can do it like this now:

I didn't understand that -1 thing at 54:25 , can anyone help me out!😭
@@tidtechnologyindepth6337 this is basically when you're telling to your machine "idk, I already gave you one number, count it yourself"
3:36:25 The accuracy keeps going up is because everytime you execute the codeblock, it takes the trained model and runs it for the specified number of epochs, since .fit() is being called on the same variable 'model'. To start training it with a fresh model, just re-initialize the variable 'model' by executing the code block with 'model = keras.Sequential([...])'.

@@abcdxx1059Very true. In the financial time series forecasting ML sphere I've only met one guy (Tom Starke) who has said anything rational. Everyone else is more or less Siraj. ML is not inherently bad but the industry is a huge elaborate scam like cryptocurrency. I haven't seen anyone build better ML models than the hand tuned hands-on real time manual adjustment algorithms I've built. I only need ML as icing on the cake to extract any last edge, and nobody seems to understand the basic principles of building a predictive model. For example none of the tutorials explain one-shot methods. That means everything out there overfits and it worse than useless! If a model can't learn in one episode it fundamentally is performing a very expensive database memorization hallucination.
Just finished the entire video, your explanations were great and I got all the examples to work on my local machine, so kudos it was an amazing course :)
46:55
don't mind me, just reminding myself
Thank you so much! After finishing some high level ai courses i was in search for a hands-on tutorial an this course was exactly the right "depth" i was searching for.
Nice to see, that it's not necessary to understand every confusing math formula in depth to get started using ai.
Another video need to be saved :) Thank you so much Tim!! ❤️

I'm only 35 minutes in but just have to make a comment and let you know I love the way you present this and your communication is great. I appreciate your time making this and I'm very glad you did! Thanks Dawg
Every video I've watched on Machine learning assumes we're in 1st grade and a college math major at the same time.
"A tensor is a generalization of multidimensional vectors or matrices blah blah blah"
5 mins later
"Slope is rise over run."
It's easier to explain what slope is then what a tensor is. It boggles your mind. Vector already represents multiple dimensions, and tensor is a multidimensional vector? That's pretty much impossible to visualise and get an intuition for. Slopes on the other hand, is rise over run.
I get what you mean, either you end up in some multivariable calculus explanaition or a lame ass "just a weighted sum bro aka Siraj Raval"
He just missed the chance to end the introduction perfectly at 30:00
explain the joke please
The geek
@@perkyelixir2254 bruh thank you
I feel like you're rushing through the subject too often in this course, still probably the best free course on TF out there
Wow. Did you just release this? Lucky me
I can't fucking believe this is available for free! I have literally no coding background! still was able to make sense of most of the stuff!
What a timing! I've just finished a teoreticall ml course and it's time for some practise :D
