Apriori Algorithm
The Apriori algorithm is a classical algorithm in data mining that we can use for these sorts of applications (i.e. recommender engines). So It is used for mining frequent item sets and relevant association rules. It is devised to operate on a database containing a lot of transactions, for instance, items brought by customers in a store.
It is very important for effective Market Basket Analysis and it helps the customers in purchasing their items with more ease which increases the sales of the markets. It has also been used in the field of healthcare for the detection of adverse drug reactions.
A key concept in Apriori algorithm is that it assumes that:
1. All subsets of a frequent item sets must be frequent
2. Similarly, for any infrequent item set, all its supersets must be infrequent too.

I've searched numerous videos on Apriori Algorithm, and I came across your video. Your video is really helpful and easy to understand with all the illustrations. Thank you!
Man I can see the amount of effort put into this video and thanks for explaining it clearly!
my hero!! thank you. Still don't know why I'm paying my university while I don't get theirs lectures.
Haha 😁 glad I can help. I get a lot of comments saying that they understand the topic better from my lectures rather than from their professors. 😋
because of your university you ended up to this video
*their lectures
You have explained it very well with nice illustrations. Thank you very much for the video.
very good example. self joining rule to create 3-Itemsets from 2-Itemsets is so important
This is great! Helped me explain to my colleagues!
Thank you very much for simple explanation. Managed to finish my assignment in minutes!
You forgot to mention the pruning part of the algorithm, to eliminate large number of sets. based on the principal that if a set is below the required minimum count then any superset can be ignored.
Dude, the first video I clicked and it was a genuinely good explanation
dear Augmented startups
thank you for the clear explanation, please make it as a playlist and connect with chapters :)
thank you very much
I was trying to understand the steps from quite some time.... but was not able to... Thanks a lot for this video.. Now I have the required clarity to apply this algo..
Your video is much appriciated :) Its fluent and clear presentation also helps alot !
+Robert Eriksen I'm really glad you enjoyed it and that it helped. :) Thank you for the comment.
Great video, it really helps in understanding this concept. I just wasn't sure at some point if it was milk or mulk you were saying. Anyways very useful video. Also was looking for the video where the algorithm is implemented in python
Beer has a frequency of 3
Thank you for making this video, it has been really helpful.
I'm really glad that it helped you :)
Very interesting! This past Valentine's Day I noticed at the store the "heart chocolates" were not in the front of the store, but were in the back of the store next to the milk. ...make sense that when you buy milk you will most likely buy chocolate.
Thank you! It helped a lot. It is very well and simple explained :)
+Jessica Rocha I'm really glad that I could help :). Thank you for the comment! :)
very nice bro.thank you
This is easy to understand, thank you for this content :)
You are most welcome Patricia :)
This helped a lot thanks
Hi Augmented Startups, Thank you for taking the time to produce these wonderfully helpful videos! I've noticed that at time marker 8:30, you count the number of beer entries as equal to 2 when it appears that there are three 1's present within its column. Is this a typo or am I missing some minor detail? Have a great day! :-)
The same question, I think beer should be 3.
This guy's english is on the level of 25 years old oils settled in the kitchen sink pipes.
Good job! Awesome stuff.
Thank you, I really appreciate the comment :)
Excellent video, thank you very much
Thank you :)
easy understanding this is....for beginners it is well and good
+SUGANTHI R thank you so much for the comment. I really appreciate it :)
thanks for the videos. very clear and easy to understand
Thanks so much Jason. I'm glad it was clear 😁🤟
thanks Sir, I've Learnt a lot from you video..
thank you the effort.
Does it mean the algorithm would eliminate more options for each progression stage if one set up additional thresholds types as well?
Hi Augmented Startups, I would like to confirm about the formula for confidence at 6:05 and life at 6:58. Are the numerator supposed to be the support (X n Y)?? Your clarification is much appreciated
I had the same cocern, but it looks to be a typo here, Indeed it should be A intersection B, as we are considering itemset for transaction containing both A AND B.
Great explanation
Hello not sure if you are going to answer this but when do you stop a creating bigger itemsets, for example, why did you stop at 3-itemsets, instead of checking for 4-itemsets
what if the frequency in 6th step is equal to both itemsets? Is that possible?
What a nice explanation !
Thank you for the comment 😁. Glad you enjoyed it.
In step one, the frequency of beer is "3" not 2 (8:29)
great explanation
Clear, thanks
Great video mate, really appreciated.
The frequency of Beer is 3 not 2
its 2 because, he drank one.
lol
@@paulalwin91 oh god lol
Yes apologies, 😋 it is 3. Thanks for the correction.
@@paulalwin91 you are hilarious man
Fantastic
ask. Is it if we only want or are only able to make 3 iterations, does that violate the Apriori concept itself?
Is the transaction item unique? How bout different transaction id with same items ?
Thank you so much
Thanks!
Thank u sir really helpful for me
+Merlyn merry I'm glad I could help 😘
Thanks a lot!
Thank you!
You are most welcome 😁
Nicely done!
Thank you so much bro 🙏
Confidence = support(X) / Number of occurrences of X in itemset
where X is an item.
marvelous video
+Muhammad Ijaz awesome ! Thank you ,😎
Excelent Thank you!
Thank you so much for the comment 😁
Is this machine learning a linear or non-linear?
Great explanation!
Thank you THE G. :). I am really glad the video was explained well :). If you have anything that you want me to make a video about, just use the hashtag #augmentedstartups with your comment and I'll see what I can do.

Is support explained properly?
Number 1 on TH-cam
5:56 There's a mistake, confidence has an intersection in the numerator, not a union.
en.wikipedia.org/wiki/Association_rule_learning#Confidence
No, the union is correct because the support refers to the union of the items in the two sets. However, in terms of probability, it will indeed be rewritten as the probability of the intersection of the two events that a transaction contains either one of the item sets respectively. This is nicely explained in the Wikipedia article on "Association rule learning".
Vídeo maravilhoso !
Thank you so much :)
@5:55 conf(X->Y) = supp(X,Y)/supp(X) or P(Y|X)
It is the same thing i.e. the formula is the same
at the 10:42 mark -- why are we only considering the triples onion-potato-burger and onion-burger-milk? why not onion-milk-burger, for example?
I do not really understand the conviction measure. What it tells us? I mean, big values mean what? Or values lower than 0 means what? I don´t understand the measure even reading its definition in papers. Can anyone help me?
Hi, where is the lecture where we can implement the Apriori algorithm in python?
Video was awesome by the way. THANKS!
Thank you Bangtan Topia :). We currently don't have the coding part but we can make a video on this if we get enough likes on this comment. Otherwise If you have anything that you want me to make a video about, just use the hashtag #augmentedstartups with your comment and I'll see what I can do.

I believe onions potatoes and milk is also a valid possibility with an item size of 3. Even though it gets a count of 2 and will be eliminated anyways.
thx
Thanking you for the lecture. I am disappointed for the apriori step summary passage, because it's not the above derived problem summary. So please correctly complete the post. Because first I trusted blindly then I check it before share that for my friends. Thanking you
Hi, @augmented startups, That was a great video made with great effort. I learned a lot. But I think the formula you said for confidence is contradicting with the formula what my lecturer was telling me. I cross checked with some websites about this and they use intersection of X and Y instead of union of X Y.
Thank you Harsha Vardhan :) as well as for the feedback. If you have anything that you want me to make a video about, just use the hashtag #augmentedstartups with your comment and I'll see what I can do.

@@Augmented_AI sir I’m telling you this as I know half of my uni mates are watching this video to get an overview of the algorithm. I just don’t want a bad reputation going on with your channel as you people helped me more than my lectures 😅. Anyways will do see you around 😁😏
@8:32 , beer = 3, not 2?
there is mistake on 8:35 min: beer 3 not 2
How does one make such cartoon drawings?
what is the meaning of the exclamation(!) point in step 5? thank you
It is the factorial operation
Why at 10.48 did't you include onion, potato, milk?
I agree. It should be included..
Because itemset(union and milk) is threshold 9:53 step5, so he skipped it!!
I want to ask. How to make array list but data get from json?
use any library to process the json, and loop it and fill the array list
paul alwin do you have tutorial about it in unity ?
No bro just Google the steps which I mentioned, google json lib for unity
hey, its that finematics guy
in 5:56 , it should be the support of X AND Y, not X union Y, right?
It's indeed a mistake, it's an intersection (AND), not a union (OR) like in the video.
It's a union, not an intersection! He put it correctly
I had to double-check my speaker to see if anything is wrong.
In step 6 where we create 3items set, you have not considered the combination of onion, burger and milk
The value of beer is 2 at 8:32 . So I think transaction id T6 beer value is 0.
Onion Burger Milk will not be considered as the combination of Onion Milk and Burger Milk were disregarded in the previous step.
any idea what's the animation software used on this. haha.
Videoscribe
@@Augmented_AI ah naise
Oooo good
Thank you so much 😁
Its ok
Uncle
Aa wt
Beer is 3 not 2
IF 3 DA BEST
beer supposed to be 3
I hate it when all lecturer took the exact same question from the internet without checking if it is correct or not.
I've seen this onion potato burger milk burger sample many times, and most of them counted the beer as 2.
Obviously this happen when you all just copy and paste the answer one from another.
I appreciate your effort in making videos,
but please be more responsible, at least check the teaching material before making it a video.
Nice but long
This is actually eclat
The formula for lift is wrong. It should be Supp ( A and B )/ Supp(A)* Supp(B)
excelent video, but s beer=3
Me: Decides to study and forget about bts for a moment.
Narrator: if SUGA is purchased... SUGA SUGA i keep hearing his name help.. LOL
The information taught is great, but the hand fake-drawing everything felt unnecessary and distracting
Is your accent...French, or no?
South African :)
I don't think this algorithm is taught in kindergarten. The painting part is NOISE and distracts.
it is a good video, but i assume your not from the us. try next time to speak a bit slower so everybody can understand you better.
Hi I have a South African acsent. I'll try that for future videos but for this video you have the option to play it at half speed if it's too fast.
Very well explained. However, I wish you hadn't used a stereotypical example at the beginning where the house-wife buys healthy ingredients for the family dinner whereas a bachelor buys beer and chips.
What example would you provide instead
Just generic examples - something like Jane buys chips and onions and Joe buys beer and potatoes?
@@vijivennelakanti9430 that could also be regarded as a stereotypical example, If the guy buys beer. - it's hard to to please everyone in this day and age. My intention is behind the example is to help people to learn a complex topic and not to stereotype people. Lets rather focus on gaining knowledge in data science and helping people solve problems than focusing on irrellevant subjects. :)

thanks to your abysmal video i got an A in this class
@@siton8492 😉👍
dude you need to learn how to pronounce apriori.
