This repo will contain the implementation described in the paper:Imitation Learning from Nonlinear MPC via the Exact Q-Loss and its Gauss-Newton Approximation, availablehere. The paper was presented in December 2023 at the IEEE Conference on Decision and Control. ...
Q-loss based on the Gauss-Newton approximation of the OCP resulting in a faster training time. We validate our losses against Behavioral Cloning, the standard approach to Imitation Learning, on the control of a nonlinear system with constraints. The final results show that the Q-function-based ...
To fight against learning loss over the summer, Tennessee is funding the delivery of surprise books to keep almost a quarter million kids engaged with reading. The Govemor’s Early Literacy Foundation (GELF) expanded its K-3 Home Library program to now include all rising 1st, 2nd, and 3rd ...

The process of learning this transformation is known as deep metric learning. The triplet loss analyzes three examples (referred to as a triplet) at a time to perform deep metric learning. The number of possible triplets increases cubically with the dataset size, making triplet loss more suitable...
Continual learning aims to tackle this problem often referred to as catastrophic forgetting and to ensure sequential learning capability. We study continual learning from the perspective of loss landscapes and propose to construct a second-order Taylor approximation of the loss functions in previous ...
(G)) had a ~ 20% reduction in GluA2 RNA editing at the Q/R site. We conducted an initial phenotypic analysis of these mice, finding altered current-voltage relations (confirming expression of Ca2+-permeable AMPA receptors at the synapse). Anatomically, we observed a loss of hippocampal ...

Metric learning aims to define a distance that measures the semantic difference between the instances in a dataset. In this paper, we analyze several well-known triplet loss functions and argue that the gradients of these triplet loss functions do not move the instances in each triplet in the ...
The loss function is a vital component of a learning system, as it represents the primary learning objective, where success is determined and quantified by the system's ability to optimize for that objective successfully. 展开 年份: 2024
