In the above program, the data is stored in a dictionary that is loaded into a Pandas dataframe and then into a Dataset object from Surprise. Algorithms Based on K-Nearest Neighbours (k-NN) The choice of algorithm for the recommender function depends on the technique you want to use. For ...
Then you will select the vote_count(v) and vote_average(R) column from the q_movies data frame; Finally, you will compute the weighted average and return the result. You will define a new feature score, of which you'll calculate the value by applying this function to your DataFrame of...
