Kernel Aware Resampler

no code implementations CVPR 2023 Michael Bernasconi, Abdelaziz Djelouah, Farnood Salehi, Markus Gross, Christopher Schroers

This renders our model applicable for different types of data not seen during the training such as normals.

Generalization Comparison of Deep Neural Networks via Output Sensitivity

1 code implementation30 Jul 2020 Mahsa Forouzesh, Farnood Salehi, Patrick Thiran

We find a rather strong empirical relation between the output sensitivity and the variance in the bias-variance decomposition of the loss function, which hints on using sensitivity as a metric for comparing the generalization performance of networks, without requiring labeled data.

Learning Hawkes Processes from a Handful of Events

1 code implementation NeurIPS 2019 Farnood Salehi, William Trouleau, Matthias Grossglauser, Patrick Thiran

It is also able to take into account the uncertainty in the model parameters by learning a posterior distribution over them.

On the Reflection of Sensitivity in the Generalization Error

no code implementations25 Sep 2019 Mahsa Forouzesh, Farnood Salehi, Patrick Thiran

We find a rather strong empirical relation between the output sensitivity and the variance in the bias-variance decomposition of the loss function, which hints on using sensitivity as a metric for comparing generalization performance of networks, without requiring labeled data.

Augmenting and Tuning Knowledge Graph Embeddings

1 code implementation1 Jul 2019 Robert Bamler, Farnood Salehi, Stephan Mandt

Knowledge graph embeddings rank among the most successful methods for link prediction in knowledge graphs, i. e., the task of completing an incomplete collection of relational facts.

Probabilistic Knowledge Graph Embeddings

no code implementations27 Sep 2018 Farnood Salehi, Robert Bamler, Stephan Mandt

We develop a probabilistic extension of state-of-the-art embedding models for link prediction in relational knowledge graphs.

An Algorithmic Framework to Control Bias in Bandit-based Personalization

no code implementations23 Feb 2018 L. Elisa Celis, Sayash Kapoor, Farnood Salehi, Nisheeth K. Vishnoi

Personalization is pervasive in the online space as it leads to higher efficiency and revenue by allowing the most relevant content to be served to each user.

Coordinate Descent with Bandit Sampling

no code implementations NeurIPS 2018 Farnood Salehi, Patrick Thiran, L. Elisa Celis

Ideally, we would update the decision variable that yields the largest decrease in the cost function.

Stochastic Optimization with Bandit Sampling

no code implementations8 Aug 2017 Farnood Salehi, L. Elisa Celis, Patrick Thiran

This approach for sampling datapoints is general, and can be used in conjunction with any algorithm that uses an unbiased gradient estimation -- we expect it to have broad applicability beyond the specific examples explored in this work.

Stochastic Optimization

Dictionary Learning Based on Sparse Distribution Tomography

no code implementations ICML 2017 Pedram Pad, Farnood Salehi, Elisa Celis, Patrick Thiran, Michael Unser

We propose a new statistical dictionary learning algorithm for sparse signals that is based on an $\alpha$-stable innovation model.

Lean From Thy Neighbor: Stochastic & Adversarial Bandits in a Network

no code implementations14 Apr 2017 L. Elisa Celis, Farnood Salehi

We provide algorithms for this setting, both for stochastic and adversarial bandits, and show that their regret smoothly interpolates between the regret in the classical bandit setting and that of the full-information setting as a function of the neighbors' exploration.
