Indigenous language technologies in Canada: Assessment, challenges, and successes

no code implementations COLING 2018 Patrick Littell, Anna Kazantseva, Rol Kuhn, , Aidan Pine, Antti Arppe, Christopher Cox, Marie-Odile Junker

In this article, we discuss which text, speech, and image technologies have been developed, and would be feasible to develop, for the approximately 60 Indigenous languages spoken in Canada.

Inverting the Turán Problem

1 code implementation6 Nov 2017 Joseph Briggs, Christopher Cox

Classical questions in extremal graph theory concern the asymptotics of $\operatorname{ex}(G, \mathcal{H})$ where $\mathcal{H}$ is a fixed family of graphs and $G=G_n$ is taken from a "standard" increasing sequence of host graphs $(G_1, G_2, \dots)$, most often $K_n$ or $K_{n, n}$.

Stability of periodic orbits in no-slip billiards

2 code implementations10 Dec 2016 Christopher Cox, Renato Feres, Hong-Kun Zhang

Rigid bodies collision maps in dimension two, under a natural set of physical requirements, can be classified into two types: the standard specular reflection map and a second which we call, after Broomhead and Gutkin, no-slip.

Classification with Sparse Overlapping Groups

no code implementations18 Feb 2014 Nikhil Rao, Robert Nowak, Christopher Cox, Timothy Rogers

In this paper, we are interested in a less restrictive form of structured sparse feature selection: we assume that while features can be grouped according to some notion of similarity, not all features in a group need be selected for the task at hand.

Sparse Overlapping Sets Lasso for Multitask Learning and its Application to fMRI Analysis

no code implementations NeurIPS 2013 Nikhil Rao, Christopher Cox, Robert Nowak, Timothy Rogers

In this paper, we are interested in a less restrictive form of multitask learning, wherein (1) the available features can be organized into subsets according to a notion of similarity and (2) features useful in one task are similar, but not necessarily identical, to the features best suited for other tasks.
