A Methodology for Exploring Deep Convolutional Features in Relation to Hand-Crafted Features with an Application to Music Audio Modeling

1 code implementation31 May 2021 Anna K. Yanchenko, Mohammadreza Soltani, Robert J. Ravier, Sayan Mukherjee, Vahid Tarokh

In this work, we instead take the perspective of relating deep features to well-studied, hand-crafted features that are meaningful for the application of interest.

GeoStat Representations of Time Series for Fast Classification

no code implementations13 Jul 2020 Robert J. Ravier, Mohammadreza Soltani, Miguel Simões, Denis Garagic, Vahid Tarokh

GeoStat representations are based off of a generalization of recent methods for trajectory classification, and summarize the information of a time series in terms of comprehensive statistics of (possibly windowed) distributions of easy to compute differential geometric quantities, requiring no dynamic time warping.

A Distributed Online Convex Optimization Algorithm with Improved Dynamic Regret

no code implementations12 Nov 2019 Yan Zhang, Robert J. Ravier, Michael M. Zavlanos, Vahid Tarokh

In this paper, we consider the problem of distributed online convex optimization, where a network of local agents aim to jointly optimize a convex function over a period of multiple time steps.
