Exploring Compositional Image Retrieval with Hybrid Compositional Learning and Heuristic Negative Mining

EMNLP 2022finding

Compositional image retrieval (CIR) is a challenging retrieval task, where the query is composed of a reference image and a modification text, and the target is another image reflecting the modification to the reference image. Due to the great success of the pre-trained vision-and-language model CLI…

Efficient Statistical Tests: A Neural Tangent Kernel Approach

ICML 2021spotlight

For machine learning models to make reliable predictions in deployment, one needs to ensure the previously unknown test samples need to be sufficiently similar to the training data. The commonly used shift-invariant kernels do not have the compositionality and fail to capture invariances in high-dim…

Stochastic Whitening Batch Normalization

CVPR 2021poster

Batch Normalization (BN) is a popular technique for training Deep Neural Networks (DNNs). BN uses scaling and shifting to normalize activations of mini-batches to accelerate convergence and improve generalization. The recently proposed Iterative Normalization (IterNorm) method improves these propert…

Adaptive Hierarchical Down-Sampling for Point Cloud Classification

CVPR 2020poster

Deterministic down-sampling of an unordered point cloud in a deep neural network has not been rigorously studied so far. Existing methods down-sample the points regardless of their importance for the network output and often address down-sampling the raw point cloud before processing. As a result, s…
