- Title: Perceptron Collaborative Filtering
- Authors: Arya Chakraborty,
- Abstract summary: A recommender system is a subclass of information filtering system that provide suggestions for items that are most pertinent to a particular user.
A perceptron or a neural network is a machine learning model designed for fitting complex datasets using backpropagation and gradient descent.
We will use the perceptron in the recommender system to fit the parameters i.e., the data from a multitude of users and use it to predict the preference/interest of a particular user.

- Abstract: While multivariate logistic regression classifiers are a great way of implementing collaborative filtering - a method of making automatic predictions about the interests of a user by collecting preferences or taste information from many other users, we can also achieve similar results using neural networks. A recommender system is a subclass of information filtering system that provide suggestions for items that are most pertinent to a particular user. A perceptron or a neural network is a machine learning model designed for fitting complex datasets using backpropagation and gradient descent. When coupled with advanced optimization techniques, the model may prove to be a great substitute for classical logistic classifiers. The optimizations include feature scaling, mean normalization, regularization, hyperparameter tuning and using stochastic/mini-batch gradient descent instead of regular gradient descent. In this use case, we will use the perceptron in the recommender system to fit the parameters i.e., the data from a multitude of users and use it to predict the preference/interest of a particular user.

Learning [131.2910403490434]
Data scientists typically collect as many features as possible into their datasets, and even engineer new features from existing ones.
Existing benchmarks for tabular feature selection consider classical downstream models, toy synthetic datasets, or do not evaluate feature selectors on the basis of downstream performance.
We construct a challenging feature selection benchmark evaluated on downstream neural networks including transformers.
We also propose an input-gradient-based analogue of Lasso for neural networks that outperforms classical feature selection methods on challenging problems.

Recommendation [133.8758914874593]
Capturing the dynamics in user preference is crucial to better predict user future behaviors because user preferences often drift over time.
Many existing recommendation algorithms -- including both shallow and deep ones -- often model such dynamics independently.
This paper considers the problem of embedding a user's sequential behavior into the latent space of user preferences.
