-[More Information Needed]
+MLM is a technique in which you take your tokenized sample and replace some of the tokens with the <mask> token and train your model with it. The model then tries to predict what should come in the place of that <mask> token and gradually starts learning about the data. MLM teaches the model about the relationship between words
+
+Eg. Suppose you have a sentence - 'Deep Learning is so cool! I love neural networks.', now replace few words with the <mask> token.
+
+Masked Sentence - 'Deep Learning is so <mask>! I love <mask> networks.'
