Non-Ideal Program-Time Conservation in Charge Trap Flash for Deep Learning

no code implementations12 Jul 2023 Shalini Shrivastava, Vivek Saraswat, Gayatri Dash, Samyak Chakrabarty, Udayan Ganguly

Training deep neural networks (DNNs) is computationally intensive but arrays of non-volatile memories like Charge Trap Flash (CTF) can accelerate DNN operations using in-memory computing.

FeFET-based MirrorBit cell for High-density NVM storage

no code implementations6 Apr 2023 Paritosh Meihar, Rowtu Srinu, Vivek Saraswat, Sandip Lashkare, Halid Mulaosmanovic, Ajay Kumar Singh, Stefan Dünkel, Sven Beyer, Udayan Ganguly

A TCAD simulation is also presented to explain the origin and working of MirrorBit states based on the FeFET model calibrated using the GlobalFoundries FeFET device.

A temporally and spatially local spike-based backpropagation algorithm to enable training in hardware

no code implementations20 Jul 2022 Anmol Biswas, Vivek Saraswat, Udayan Ganguly

Although signed gradient values are a challenge for spike-based representation, we tackle this by splitting the gradient signal into positive and negative streams.

Algorithm For 3D-Chemotaxis Using Spiking Neural Network

no code implementations30 Jun 2021 Jayesh Choudhary, Vivek Saraswat, Udayan Ganguly

In this work, we aim to devise an end-to-end spiking implementation for contour tracking in 3D media inspired by chemotaxis, where the worm reaches the region which has the given set concentration.

Simplified Klinokinesis using Spiking Neural Networks for Resource-Constrained Navigation on the Neuromorphic Processor Loihi

no code implementations4 May 2021 Apoorv Kishore, Vivek Saraswat, Udayan Ganguly

C. elegans shows chemotaxis using klinokinesis where the worm senses the concentration based on a single concentration sensor to compute the concentration gradient to perform foraging through gradient ascent/descent towards the target concentration followed by contour tracking.

Hardware-Friendly Synaptic Orders and Timescales in Liquid State Machines for Speech Classification

no code implementations29 Apr 2021 Vivek Saraswat, Ajinkya Gorad, Anand Naik, Aakash Patil, Udayan Ganguly

In this work, we analyze the role of synaptic orders namely: {\delta} (high output for single time step), 0th (rectangular with a finite pulse width), 1st (exponential fall) and 2nd order (exponential rise and fall) and synaptic timescales on the reservoir output response and on the TI-46 spoken digits classification accuracy under a more comprehensive parameter sweep.

Adaptive Chemotaxis for improved Contour Tracking using Spiking Neural Networks

no code implementations1 Aug 2020 Shashwat Shukla, Rohan Pathak, Vivek Saraswat, Udayan Ganguly

In particular, we focus on the problem of contour tracking, wherein the bot must reach and subsequently follow a desired concentration setpoint.

Predicting Performance using Approximate State Space Model for Liquid State Machines

no code implementations18 Jan 2019 Ajinkya Gorad, Vivek Saraswat, Udayan Ganguly

Lyapunov exponent (mu), used to characterize the "non-linearity" of the network, correlates well with LSM performance.
