What is TF-IDF?
TF-IDF means Term Frequency-Inverse File Frequency. It's a statistical measure used to assess how crucial a word is to a file in a collection or corpus.
Term Frequency (TF): This determines how regularly a term appears in a file. The intuition here is that the more often a term appears in a file, the more pertinent it may be.
Inverse File Frequency (IDF): This element gauges how essential a term is across all documents. Words that appear in numerous files are less helpful than those that appear in just one or few.
The formula for TF-IDF can be revealed as:
[\ textTF-IDF(t, d) = \ textTF(t, d) \ times \ textIDF(t)]
Where:
( t) = term ( d) = document
