What is word embedding in deep learning? Quora

Then you get your probabilities for Naive Bayes using the formula you posted (adding up the TF-IDF weights instead of simply counting the number of words). Look at section 4.4 in this paper (pdf) . The whole process from raw documents to NB probabilities is outlined.

computer vision Incremental Online Update of Tf-IDF

Tf-Idf is computed by multiplying a local component like term frequency (TF) with a global component, that is, inverse document frequency (IDF) and optionally normalizing the result to unit length. As a result of this, the words that occur frequently across documents will get downweighted.

What does word embedding weighted by tf-idf mean

The first is a simple combination, where each tweet is represented by the average of the word embedding vectors of the words that compose the tweet. The second approach also averages the word embedding vectors, but each embedding vector is now weighted (multiplied) by the tf

Word representation SVD LSA Word2Vec SlideShare

Have you guys tried to compare the performance of TF-IDF features* with a shallow neural network classifier vs a deep neural network models like an RNN that has an embedding layer with word embedding as weights next to the input layer? I tried this on a couple of tweet datasets and got surprising results: f1 score of~65% for the TF-IDF vs ~45% for the RNN. I tried the setup embedding
