KDD 2023 FL4Data-Mining Workshop2023Federated learning (FL) enables multiple client devices to train a single machine learning model collaboratively. As FL often involves various smart devices, it is important to adapt the FL pipeline to accommodate device resource constraints. This work addresses the problem of training and storing memory-intensive deep neural network architectures on resource-constrained devices. Existing solutions often

ICLR 20232023Predicting the responses of a cell under perturbations may bring important benefits to drug discovery and personalized therapeutics. In this work, we propose a novel graph variational Bayesian causal inference framework to predict a cell’s gene expressions under counterfactual perturbations (perturbations that this cell did not factually receive), leveraging information representing biological knowledge

ICCV 20232023Graph convolutional networks (GCNs) enable end-to-end learning on graph structured data. However, many works assume a given graph structure. When the input graph is noisy or unavailable, one approach is to construct or learn a latent graph structure. These methods typically fix the choice of node degree for the entire graph, which is suboptimal. Instead, we propose a novel end-to-end differentiable graph

AAAI/ACM 2023 Conference on AI, Ethics, and Society2023We propose a novel taxonomy for bias evaluation of discriminative foundation models, such as Contrastive Language-Pretraining (CLIP), that are used for labeling tasks. We then systematically evaluate existing methods for mitigating bias in these models with respect to our taxonomy. Specifically, we evaluate OpenAI’s CLIP and OpenCLIP models for key applications, such as zero-shot classification, image retrieval

ICML 20232023Minimax-fair machine learning minimizes the error for the worst-off group. However, empirical evidence suggests that when sophisticated models are trained with standard empirical risk minimization (ERM), they often have the same performance on the worst-off group as a minimax-trained model. Our work makes this counterintuitive observation concrete. We prove that if the hypothesis class is sufficiently expressive
