On sampled metrics for item recommendation

Autor: Walid Krichene, Steffen Rendle

Publikováno v: KDD

Recommender systems personalize content by recommending items to users. Item recommendation algorithms are evaluated by metrics that compare the positions of truly relevant items among the recommended items. To speed up the computation of metrics, re

Neural Collaborative Filtering vs. Matrix Factorization Revisited

Autor: John Anderson, Li Zhang, Walid Krichene, Steffen Rendle

Publikováno v: RecSys

Embedding based models have been the state of the art in collaborative filtering for over a decade. Traditionally, the dot product or higher order equivalents have been used to combine two or more embeddings, e.g., most notably in matrix factorizatio

We consider the System Optimal Dynamic Traffic Assignment (SO-DTA) problem with Partial Control for general networks with physical queuing. Our goal is to optimally control any subset of the networks agents to minimize the total congestion of all age

The adjoint method provides a computationally efficient means of calculating the gradient for applications in constrained optimization. In this article, we consider a network of scalar conservation laws with general topology, whose behavior is modifi

Publikováno v: IEEE Transactions on Automatic Control. 59:714-727

This paper presents a game theoretic framework for studying Stackelberg routing games on parallel networks with horizontal queues, such as transportation networks. First, we introduce a new class of latency functions that models congestion due to the
