An Integrated Toolbox for Creating Neuromorphic Edge Applications

no code implementations12 Apr 2024 Lars Niedermeier, Jeffrey L. Krichmar

Spiking Neural Networks (SNNs) and neuromorphic models are more efficient and have more biological realism than the activation functions typically used in deep neural networks, transformer models and generative AI.

Policy Distillation with Selective Input Gradient Regularization for Efficient Interpretability

no code implementations18 May 2022 Jinwei Xing, Takashi Nagata, Xinyun Zou, Emre Neftci, Jeffrey L. Krichmar

Although deep Reinforcement Learning (RL) has proven successful in a wide range of tasks, one challenge it faces is interpretability when applied to real-world problems.

Edelman's Steps Toward a Conscious Artifact

no code implementations22 May 2021 Jeffrey L. Krichmar

In 2006, during a meeting of a working group of scientists in La Jolla, California at The Neurosciences Institute (NSI), Gerald Edelman described a roadmap towards the creation of a Conscious Artifact.

Dynamic Reliability Management in Neuromorphic Computing

no code implementations5 May 2021 Shihao Song, Jui Hanamshet, Adarsha Balaji, Anup Das, Jeffrey L. Krichmar, Nikil D. Dutt, Nagarajan Kandasamy, Francky Catthoor

We propose a new architectural technique to mitigate the aging-related reliability problems in neuromorphic systems, by designing an intelligent run-time manager (NCRTM), which dynamically destresses neuron and synapse circuits in response to the short-term aging in their CMOS transistors during the execution of machine learning workloads, with the objective of meeting a reliability target.

Domain Adaptation In Reinforcement Learning Via Latent Unified State Representation

1 code implementation10 Feb 2021 Jinwei Xing, Takashi Nagata, Kexin Chen, Xinyun Zou, Emre Neftci, Jeffrey L. Krichmar

To address this issue, we propose a two-stage RL agent that first learns a latent unified state representation (LUSR) which is consistent across multiple domains in the first stage, and then do RL training in one source domain based on LUSR in the second stage.

PyCARL: A PyNN Interface for Hardware-Software Co-Simulation of Spiking Neural Network

1 code implementation21 Mar 2020 Adarsha Balaji, Prathyusha Adiraju, Hirak J. Kashyap, Anup Das, Jeffrey L. Krichmar, Nikil D. Dutt, Francky Catthoor

We also use PyCARL to analyze these SNNs for a state-of-the-art neuromorphic hardware and demonstrate a significant performance deviation from software-only simulations.

Neuromodulated Goal-Driven Perception in Uncertain Domains

no code implementations16 Feb 2019 Xinyun Zou, Soheil Kolouri, Praveen K. Pilly, Jeffrey L. Krichmar

In uncertain domains, the goals are often unknown and need to be predicted by the organism or system.

no code implementations4 Dec 2018 Jeffrey L. Krichmar, William Severa, Salar M. Khan, James L. Olds

First, that scientific societies and governments coordinate Biomimetic Research for Energy-efficient, AI Designs (BREAD); a multinational initiative and a funding strategy for investments in the future integrated design of energetics into AI.

Unsupervised Heart-rate Estimation in Wearables With Liquid States and A Probabilistic Readout

no code implementations18 Jul 2017 Anup Das, Paruthi Pradhapan, Willemijn Groenendaal, Prathyusha Adiraju, Raj Thilak Rajan, Francky Catthoor, Siebren Schaafsma, Jeffrey L. Krichmar, Nikil Dutt, Chris Van Hoof

The novelty of our approach lies in (1) encoding spatio-temporal properties of ECG signals directly into spike train and using this to excite recurrently connected spiking neurons in a Liquid State Machine computation model; (2) a novel learning algorithm; and (3) an intelligently designed unsupervised readout based on Fuzzy c-Means clustering of spike responses from a subset of neurons (Liquid states), selected using particle swarm optimization.
