Learning from the Best: Active Learning for Wireless Communications

no code implementations23 Jan 2024 Nasim Soltani, Jifan Zhang, Batool Salehi, Debashri Roy, Robert Nowak, Kaushik Chowdhury

We evaluate the performance of different active learning algorithms on a publicly available multi-modal dataset with different modalities including image and LiDAR.

DIRECT: Deep Active Learning under Imbalance and Label Noise

no code implementations14 Dec 2023 Shyam Nuggehalli, Jifan Zhang, Lalit Jain, Robert Nowak

Our results demonstrate that DIRECT can save more than 60% of the annotation budget compared to state-of-art active learning algorithms and more than 80% of annotation budget compared to random sampling.

PathProx: A Proximal Gradient Algorithm for Weight Decay Regularized Deep Neural Networks

no code implementations6 Oct 2022 Liu Yang, Jifan Zhang, Joseph Shenouda, Dimitris Papailiopoulos, Kangwook Lee, Robert D. Nowak

Weight decay is one of the most widely used forms of regularization in deep learning, and has been shown to improve generalization and robustness.

GALAXY: Graph-based Active Learning at the Extreme

1 code implementation3 Feb 2022 Jifan Zhang, Julian Katz-Samuels, Robert Nowak

Active learning is a label-efficient approach to train highly effective models while interactively selecting only small subsets of unlabelled data for labelling and training.

Learning to Actively Learn: A Robust Approach

no code implementations29 Oct 2020 Jifan Zhang, Lalit Jain, Kevin Jamieson

Unlike the design of traditional adaptive algorithms that rely on concentration of measure and careful analysis to justify the correctness and sample complexity of the procedure, our adaptive algorithm is learned via adversarial training over equivalence classes of problems derived from information theoretic lower bounds.
