Representation Learning Using a Single Forward Pass
<|reference_start|>Representation Learning Using a Single Forward Pass: We propose a neuroscience-inspired Solo Pass Embedded Learning Algorithm (SPELA). SPELA is a prime candidate for training and inference applications in Edge AI devices. At the same time, SPELA can optimally cater to the need for a framework to study perceptual representation learning and formation. SPELA has distinctive features such as neural priors (in the form of embedded vectors), no weight transport, no update locking of weights, complete local Hebbian learning, single forward pass with no storage of activations, and single weight update per sample. Juxtaposed with traditional approaches, SPELA operates without the need for backpropagation. We show that our algorithm can perform nonlinear classification on a noisy boolean operation dataset. Additionally, we exhibit high performance using SPELA across MNIST, KMNIST, and Fashion MNIST. Lastly, we show the few-shot and 1-epoch learning capabilities of SPELA on MNIST, KMNIST, and Fashion MNIST, where it consistently outperforms backpropagation.<|reference_end|>
