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.

Symplectic Momentum Neural Networks -- Using Discrete Variational Mechanics as a prior in Deep Learning

1 code implementation20 Jan 2022 Saul Santos, Monica Ekal, Rodrigo Ventura

The combination of such formulation leads SyMos to be constrained towards preserving important geometric structures such as momentum and a symplectic form and learn from limited data.

COSMIC: fast closed-form identification from large-scale data for LTV systems

no code implementations8 Dec 2021 Maria Carvalho, Claudia Soares, Pedro Lourenço, Rodrigo Ventura

To prove its applicability to real world systems, we test with spring-mass-damper system and use the estimated model to find the optimal control path.

Decision Support Models for Predicting and Explaining Airport Passenger Connectivity from Data

no code implementations2 Nov 2021 Marta Guimaraes, Claudia Soares, Rodrigo Ventura

Predicting if passengers in a connecting flight will lose their connection is paramount for airline profitability.

Autonomous orbit determination for satelite formations using relative sensing: observability analysis and optimization

no code implementations19 Sep 2021 Pedro Rocha Cachim, João Gomes, Rodrigo Ventura

Orbit determination of spacecraft in orbit has been mostly dependent on either GNSS satellite signals or ground station telemetry.

Teaching robots to perceive time -- A reinforcement learning approach (Extended version)

no code implementations20 Dec 2019 Inês Lourenço, Bo Wahlberg, Rodrigo Ventura

In this paper, we study how to replicate neural mechanisms involved in time perception, allowing robots to take a step towards temporal cognition.

Gaussian Processes reinforcement-learning +1

A deep learning approach for understanding natural language commands for mobile service robots

no code implementations9 Jul 2018 Pedro Henrique Martins, Luís Custódio, Rodrigo Ventura

Using natural language to give instructions to robots is challenging, since natural language understanding is still largely an open problem.
