Liquid Time-constant Recurrent Neural Networks as Universal Approximators

no code implementations1 Nov 2018 Ramin M. Hasani, Mathias Lechner, Alexander Amini, Daniela Rus, Radu Grosu

In this paper, we introduce the notion of liquid time-constant (LTC) recurrent neural networks (RNN)s, a subclass of continuous-time RNNs, with varying neuronal time-constant realized by their nonlinear synaptic transmission model.

Response Characterization for Auditing Cell Dynamics in Long Short-term Memory Networks

no code implementations11 Sep 2018 Ramin M. Hasani, Alexander Amini, Mathias Lechner, Felix Naser, Radu Grosu, Daniela Rus

In this paper, we introduce a novel method to interpret recurrent neural networks (RNNs), particularly long short-term memory networks (LSTMs) at the cellular level.

Neuronal Circuit Policies

1 code implementation22 Mar 2018 Mathias Lechner, Ramin M. Hasani, Radu Grosu

We propose an effective way to create interpretable control agents, by re-purposing the function of a biological neural circuit model, to govern simulated and real world reinforcement learning (RL) test-beds.

Worm-level Control through Search-based Reinforcement Learning

no code implementations9 Nov 2017 Mathias Lechner, Radu Grosu, Ramin M. Hasani

We model the tap-withdrawal (TW) neural circuit of the nematode, \textit{C. elegans}, a circuit responsible for the worm's reflexive response to external mechanical touch stimulations, and learn its synaptic and neural parameters as a policy for controlling the inverted pendulum problem.

SIM-CE: An Advanced Simulink Platform for Studying the Brain of Caenorhabditis elegans

no code implementations18 Mar 2017 Ramin M. Hasani, Victoria Beneder, Magdalena Fuchs, David Lung, Radu Grosu

We introduce SIM-CE, an advanced, user-friendly modeling and simulation environment in Simulink for performing multi-scale behavioral analysis of the nervous system of Caenorhabditis elegans (C. elegans).

Non-Associative Learning Representation in the Nervous System of the Nematode Caenorhabditis elegans

no code implementations18 Mar 2017 Ramin M. Hasani, Magdalena Fuchs, Victoria Beneder, Radu Grosu

Caenorhabditis elegans (C. elegans) illustrated remarkable behavioral plasticities including complex non-associative and associative learning representations.

An Automated Auto-encoder Correlation-based Health-Monitoring and Prognostic Method for Machine Bearings

no code implementations18 Mar 2017 Ramin M. Hasani, Guodong Wang, Radu Grosu

We demonstrate the superiority of the AEC over many other state-of-the-art approaches for the health monitoring and prognostic of machine bearings.

Control of the Correlation of Spontaneous Neuron Activity in Biological and Noise-activated CMOS Artificial Neural Microcircuits

no code implementations24 Feb 2017 Ramin M. Hasani, Giorgio Ferrari, Hideaki Yamamoto, Sho Kono, Koji Ishihara, Soya Fujimori, Takashi Tanii, Enrico Prati

At such an intermediate scale, the firing activity in the microcircuits is governed by collective effects emerging by the background noise soliciting spontaneous firing, the degree of mutual connections between the neurons, and the topology of the connections.
