Globally Optimal Training of Neural Networks with Threshold Activation Functions

ICLR 2023poster

Threshold activation functions are highly preferable in neural networks due to their efficiency in hardware implementations. Moreover, their mode of operation is more interpretable and resembles that of biological neurons. However, traditional gradient based algorithms such as Gradient Descent canno…

Understanding Multimodal Contrastive Learning and Incorporating Unpaired Data

AISTATS 2023poster

Language-supervised vision models have recently attracted great attention in computer vision. A common approach to build such models is to use contrastive learning on paired data across the two modalities, as exemplified by Contrastive Language-Image Pre-Training (CLIP). In this paper, (i) we initia…

Sample Efficient Subspace-Based Representations for Nonlinear Meta-Learning

ICASSP 2021accepted

Constructing good representations is critical for learning complex tasks in a sample efficient manner. In the context of meta-learning, representations can be constructed from common patterns of previously seen tasks so that a future task can be learned quickly. While recent works show the benefit o…

Towards Sample-efficient Overparameterized Meta-learning

NeurIPS 2021poster

An overarching goal in machine learning is to build a generalizable model with few samples. To this end, overparameterization has been the subject of immense interest to explain the generalization ability of deep nets even when the size of the dataset is smaller than that of the model. While the pri…
