Question How to calculate relevance/score for a query asked by the user against the trained documents ? Additional context @abhishekraok @DmitryKey As relevance/score for the results obtained against the documents is very important to be...
If the idea of calculating TF-IDF makes your eyes roll back in your head, then show the top 5 terms per document, based on frequency. Again, NOT SEO. This is to help you figure out what each page/section is about, without requiring you to read every one. It’s not perfect, but ...
based on a score that combines the term frequency of a phrase within a document, and the inverse document frequency of the term within the entire URL group (aka, the corpus, in natural language processing-speak). If the idea of calculating TF-IDF makes your eyes...
Word Frequencies with TfidfVectorizer Word counts are a good starting point, but are very basic. One issue with simple counts is that some words like “the” will appear many times and their large counts will not be very meaningful in the encoded vectors. An alternative is to calculate word...
In the following two papers, it is shown that both to project all words of the context onto a continuous space and calculate the language model probability for the given context can be performed by a neural network using two hidden layers. Holger Schwenk and Jean-Luc Gauvain. Training Neural...
This, in turn, provides a population of performance measures. We can calculate the mean of these measures to get an idea of how well the procedure performs on average. We can calculate the standard deviation of these measures to get an idea of how much the skill of the procedure is expect...
