Fast and Consistent Learning of Hidden Markov Models by Incorporating Non-Consecutive Correlations

no code implementations ICML 2020 Robert Mattila, Cristian Rojas, Eric Moulines, Vikram Krishnamurthy, Bo Wahlberg

Can the parameters of a hidden Markov model (HMM) be estimated from a single sweep through the observations -- and additionally, without being trapped at a local optimum in the likelihood surface?

A Biologically-Inspired Computational Model of Time Perception

no code implementations7 Nov 2023 Inês Lourenço, Robert Mattila, Rodrigo Ventura, Bo Wahlberg

We conclude that the agent is able to perceive time similarly to animals when it comes to their intrinsic mechanisms of interpreting time and performing time-aware actions.

Cooperative System Identification via Correctional Learning

no code implementations9 Dec 2020 Inês Lourenço, Robert Mattila, Cristian R. Rojas, Bo Wahlberg

We consider a cooperative system identification scenario in which an expert agent (teacher) knows a correct, or at least a good, model of the system and aims to assist a learner-agent (student), but cannot directly transfer its knowledge to the student.
