Hi Shitij, I am not really an expert on imbalanced classes, but a first simple approach may be to drop 90% of the non-popular data, to balance the classes again ☺

Google also showed a lot of advise when I typed 'train on imbalanced classes’.

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
