Dynamic Local Regret for Non-convex Online Forecasting

Sergul Aydore, Tianhao Zhu, Dean P. Foster

NeurIPS 2019poster

We consider online forecasting problems for non-convex machine learning models. Forecasting introduces several challenges such as (i) frequent updates are necessary to deal with concept drift issues since the dynamics of the environment change over time, and (ii) the state of the art models are non-…

Invariances and Data Augmentation for Supervised Music Transcription

John Thickstun, Zaïd Harchaoui, Dean P. Foster, Sham M. Kakade

ICASSP 2018accepted

This paper explores a variety of models for frame-based music transcription, with an emphasis on the methods needed to reach state-of-the-art on human recordings. The translation-invariant network discussed in this paper, which combines a traditional filterbank with a convolutional neural network, w…
