I am struggling while solving kaggle MP Neuron competiton

After solving MP neuron like-unlike mobile classifier i got value of b=10.(Thresholding).
In training set the accuracy for b=10 is 85 percent .
But after applying it on test data and submitting it on kaggle ,
The kaggle score accuracy is 65 percent
i am not expecting this huge reduction ,Model is all right

Hi @Pranav_Kushare,
You can try out different preprocessing steps, and refer to some of the public notebooks for some good ideas.
