TF-IDF(tf.idf) stands for term frequency inverse document frequency. Its formula is given by: tf.idf = tf * idf tf takes care of the number of time the term occurs. Taking just the frequency count will outweigh documents large in size. Hence we normalise this by dividing by the length of document which is total number…

## What is the formula for tf.idf ? Why do we use ‘log’ in idf formula ?
