    Great, you have a way of distilling concepts into explanations I can understand. I now know that the tfidf score is inherently flexible.

    Wow, finally I hv found a place where I understood what the hell TF IDF is. Thanks a ton Daniel!!!

    Was on the point of starting the rather daunting task of doing this myself... then mr shiffman to the rescue again :))

    @Daniel Shiffman If you ever do more videos on text analysis, could you talk about stemming and synonymy?

    Hi Daniel, a great challange, as usual! One more thing learned!

  • @PixelOutlaw

    Huffman encoding is also a great thing to teach based on frequency. :) Maybe another tutorial?
    Sorry if I've missed it and you've done one.

    If i were to become a tutor in future, should i undergo a specialized training for being humorous while teaching or is it that it's an inborn talent that Daniel has. It took me an hour to go through the video not to understand the concept but to rewind and play the funny moments again and again.

    Actually, you can create a variable within a lower scope - just replace the 'var' keyword with 'let'.
    This was introduced in ES6, which means it's not completely supported in all browsers, but you should be fine in chrome, and definitely in node (as long as you are using recent versions).

    Nice video... But, If you not only check if the word occurs in the other documents, but also count the number of occurences in that other documents it would definetly give you the more precise outcome. Hopefully it makes sense.

  • @IceMetalPunk
    @IceMetalPunk 5 ปีที่แล้ว

    For the df value, couldn't you just loop over all the documents (say with iterator i) and then over the keys (with iterator j) and just use allwords[i].indexOf(keys[j]) >= 0 to determine if the word is in the document? Then you don't need the precalculated tempcounts, and it's just those two loops, O(unique_words * total_documents).

    hi daniel,
    can you make a video about networks?
    let's say something like percolation or disease spreading
    i have'nt seen a video like that, who deals with nodes and edges.
    thank you and chatima tova!
    your videos are great

      Maybe you need to use special regular expressions for the Ge'ez script. Tell me if you found a solution in the meantime.

      It'll help with the concepts and the code can be ported, but I am using JavaScript rather than Java.
