Learning a Neuron by a Shallow ReLU Network: Dynamics and Implicit Bias for Correlated Inputs

Dmitry Chistikov, Matthias Englert, Ranko Lazic

We prove that, for the fundamental regression task of learning a single neuron, training a one-hidden layer ReLU network of any width by gradient flow from a small initialisation c…

Adversarial Reprogramming Revisited

Matthias Englert, Ranko Lazic

Adversarial reprogramming, introduced by Elsayed, Goodfellow, and Sohl-Dickstein, seeks to repurpose a neural network to perform a different task, by manipulating its input without…

Human-like Relational Models for Activity Recognition in Video

Joseph Chrol-Cannon, Andrew Gilbert, Ranko Lazic +2

Video activity recognition by deep neural networks is impressive for many classes. However, it falls short of human performance, especially for challenging to discriminate activiti…

The Reachability Problem for Petri Nets is Not Elementary

Wojciech Czerwinski, Slawomir Lasota, Ranko Lazic +2

Petri nets, also known as vector addition systems, are a long established model of concurrency with extensive applications in modelling and analysis of hardware, software and datab…

Universal trees grow inside separating automata: Quasi-polynomial lower bounds for parity games

Wojciech Czerwiński, Laure Daviaud, Nathanaël Fijalkow +3

Several distinct techniques have been proposed to design quasi-polynomial algorithms for solving parity games since the breakthrough result of Calude, Jain, Khoussainov, Li, and St…

When is Containment Decidable for Probabilistic Automata?

Laure Daviaud, Marcin Jurdziński, Ranko Lazić +3

The emptiness and containment problems for probabilistic automata are natural quantitative generalisations of the classical language emptiness and inclusion problems for Boolean au…
