What is Word2Vec? A Simple Explanation | Deep Learning Tutorial 41 (Tensorflow, Keras & Python)

A very simple explanation of word2vec. This video gives an intuitive understanding of how word2vec algorithm works and how it can generate accurate word embeddings for words such that you can do math with words (a famous example is king - man + woman = queen)

I started searching wordtovec videos after failing to understand it by following NG's lessons. That is the single video that can actually tell that the word embeddings are 'the side effects' of the training process and this is how it finally clicked for me. Thank you very much!

Well done. This is one of the best course on word2vec so far. I do have a master degree in AI and event that I did not work professionaly in the field your cour brough a lot of souvenirs haaa.. During my master 15 years ago I introduced an archaich method for resolving question/answering based on linkgramar, wordnet, verbnet and semnet. At the end of my syntactical analysis I also discovered that by just using world context it was possible to comme up with a vector representation of named entities.. The innovation is here is the use of neural network to give a value to the world. This is just brilliant. In my thesis I was already showing that language is just a code representing a subjective version of one universe and that human and animal comunicate using theirs own code.

[@vitocorleone1991]

Brilliant

[@josephvanname3377]

The king-man+woman=queen equation tells me that we are not embedding words into a vector space but into an affine space which is like a vector space but where we do not have a notion of a zero vector. Perhaps we can obtain a zero vector simply by taking the weighted average over all words or by doing some regularization during training so that we naturally get a zero vector. What will the zero vector mean anyways?

[@rahulsoni412]

Thanks a lot for explaining this using a neural network diagram :)

@@codebasics can you explain how the number of weights are calculated in word embedding, I mean the number of total weights. I was getting confused while calculating the number of weights.

There's a subtle mistake in your CBOW explanation at 8:34 . In CBOW the target is always the central word based on context i.e the surrounding word . That means for a substring "Emperor ordered his" and window size of 3 the target is "ordered" and features are "Emperor , this"

Hello I have doubt in this explanation, aren't all the weights gonna be same when our neural network is trained ? what I mean is once we train a network W(T)X is what triggers a output node so how do we have different weights for every output word

Hi, it is a wonderful explanation for word2vec I've ever seen.I have a question,I have my own corpus and I have built multiple wor2vec models, How to evaluate these models and how am I gonna choose the best one???

[@codebasics]

One approach is to take a classification or some other NLP problem in your domain and build NLP classification model using your embeddings. You can then check the performance of those models to evaluate how effective embeddings are

[@uwaisahamedimad556]

@@codebasics thanks a lot for the reply. based on your answer it seems like there is no standard or at least a well-established evaluation method for the performance of word embeddings.

I think you mean 'side products' rather than 'side effect'?

[@Cooldude5786]

The statement "King - man + woman = Queen" is well-known in machine learning. However, when we examine the characteristics of a king, they often include being super rich, having authority, and possibly not having a tail. Yet, there is a contradiction: a lion is also referred to as a king, and it does have a tail. How can a computer differentiate between a human king and an animal king? Doesn't this introduce bias since the training corpus typically associates "king" with humans rather than animals? Just because something appears less frequently or is absent from the corpus doesn't mean it lacks value or significance.
