Faster Algorithms for Learning Convex Functions

no code implementations2 Nov 2021 Ali Siahkamari, Durmus Alp Emre Acar, Christopher Liao, Kelly Geyer, Venkatesh Saligrama, Brian Kulis

For the task of convex Lipschitz regression, we establish that our proposed algorithm converges with iteration complexity of $ O(n\sqrt{d}/\epsilon)$ for a dataset $\bm X \in \mathbb R^{n\times d}$ and $\epsilon > 0$.

Piecewise Linear Regression via a Difference of Convex Functions

2 code implementations ICML 2020 Ali Siahkamari, Aditya Gangrade, Brian Kulis, Venkatesh Saligrama

We present a new piecewise linear regression methodology that utilizes fitting a difference of convex functions (DC functions) to the data.

Learning to Approximate a Bregman Divergence

2 code implementations NeurIPS 2020 Ali Siahkamari, Xide Xia, Venkatesh Saligrama, David Castanon, Brian Kulis

Bregman divergences generalize measures such as the squared Euclidean distance and the KL divergence, and arise throughout many areas of machine learning.

Conditioning Deep Generative Raw Audio Models for Structured Automatic Music

no code implementations26 Jun 2018 Rachel Manzelli, Vijay Thakkar, Ali Siahkamari, Brian Kulis

Existing automatic music generation approaches that feature deep learning can be broadly classified into two types: raw audio models and symbolic models.
