I am not able to install opencv in jupyter notebook ?
Please, somebody help.
# sort by -count, word. item = (word, count)return -item, item
Need explanation. How it sorted by "count" by adding "-" sign in "item" ?
You have taken the mean and std only for trainData(Not all data). But during the normalization you have normalized the 'trainData' as well as 'testData' with same means and std. Why ?
I think you had to calculate the mean and std value for whole data sets.
