Backpropagation-Free Deep Learning with Recursive Local Representation Alignment

AAAI 2023technical

Training deep neural networks on large-scale datasets requires significant hardware resources whose costs (even on cloud platforms) put them out of reach of smaller organizations, groups, and individuals. Backpropagation (backprop), the workhorse for training these networks, is an inherently sequent…

Backprop-Free Reinforcement Learning with Active Neural Generative Coding

AAAI 2022technical

In humans, perceptual awareness facilitates the fast recognition and extraction of information from sensory input. This awareness largely depends on how the human agent interacts with the environment. In this work, we propose active neural generative coding, a computational framework for learning ac…

Recognizing and Verifying Mathematical Equations using Multiplicative Differential Neural Units

AAAI 2021technical

Automated mathematical reasoning is a challenging problem that requires an agent to learn algebraic patterns that contain long-range dependencies. Two particular tasks that test this type of reasoning are (1)mathematical equation verification,which requires determining whether trigonometric and line…

A Neural Temporal Model for Human Motion Prediction

CVPR 2019poster

We propose novel neural temporal models for predicting and synthesizing human motion, achieving state-of-the-art in modeling long-term motion trajectories while being competitive with prior work in short-term prediction and requiring significantly less computation. Key aspects of our proposed system…
