Building a recommendation system using deep learning

[@kochasaito4628]

That is a very self-containing talk, thanks Abhishek!

[@ramonsantiago4573]

Question: Instead of splitting your data into parts (train/validation) why didn't you create a user - items matrix and then mask some values for the validation?

[@sumitvaise5452]

Copied: Consider using the user-items matrix with masking if: Your primary data source is implicit feedback Temporal order of recommendations is crucial You are interested in matrix factorization techniques Traditional train/validation splitting might be better if: You have lots of explicit ratings Your matrix is extremely sparse Computational speed is a major priority

Hi Abhishek, can you do a testing and deployment series of ML/DL models. I really wanted to get that insight and love the content. I have learnt a lot from your videos and live sessions

Thank you very much for the helpful giude! Pls make a video about how to get recommended movies by user ID using this model ) kinda stuck with it

Hi Abhishek, The video was very informative can you please upload part 2 of it soon. Thanks 😇

[@peregudovoleg]

Hi. Still strange how it run w/o the torch import as well as without self.optimizer arg in fetch_scheduler(). You didn't define self.optimizer anywhere. Unless tez is taking care of it or something.

Im a bit green as far as OOP is concerned. In the MovieDataSet class, in the 3rd function _getitem_, I didn't understand what you are doing. Can you please explain?

But how do you input a movie name and then get recommendations based on it??

I don't know how to install pandas, it say "Import "pandas" could not be resolved from source Pylance". I don't find a solution

[@abhishekkrthakur]

you can install pandas using pip. but for now, i would recommend you to use the environment in kaggle notebooks. we will talk about custom libraries in a few days!

hi can you please specify how after training the model, one can find say 20 recommendations for each user. Do we do that using two loops where we predict the rating for each user and for each item and then, pick top max rating?? Please specify

Nice one Abhishek! Was wondering how would you handle the cold start problem with this, does this only allow for users seen before in the training set ?

[@abhishekkrthakur]

cold-start is always a problem with recommenders. a simple way to handle this would be to show the most popular items. if there are some known user characteristics, you can find the most similar user and then most popular items., or random items :)

this stratify parameter in train_test_split doesn't work for me in multi labels and it throws error saying found one class but needs atleast two...my labels were 25k...so what i did for my project is reduce the labels to consider atleast more 200 times (arbitrary) present in dataset and it reduces to 300+ labels and then use third party stratification library to distribute labels properly and it works... don't know why scikit learn stratify don't work for me...
