OCELOT: Overlapped Cell on Tissue Dataset for Histopathology

CVPR 2023poster

Cell detection is a fundamental task in computational pathology that can be used for extracting high-level medical information from whole-slide images. For accurate cell detection, pathologists often zoom out to understand the tissue-level structures and zoom in to classify cells based on their morp…

Online Hyperparameter Meta-Learning with Hypergradient Distillation

ICLR 2022spotlight

Many gradient-based meta-learning methods assume a set of parameters that do not participate in inner-optimization, which can be considered as hyperparameters. Although such hyperparameters can be optimized using the existing gradient-based hyperparameter optimization (HO) methods, they suffer from…

Sparse DETR: Efficient End-to-End Object Detection with Learnable Sparsity

ICLR 2022poster

DETR is the first end-to-end object detector using a transformer encoder-decoder architecture and demonstrates competitive performance but low computational efficiency. The subsequent work, Deformable DETR, enhances the efficiency of DETR by replacing dense attention with deformable attention, which…

Large-Scale Meta-Learning with Continual Trajectory Shifting

ICML 2021spotlight

Meta-learning of shared initialization parameters has shown to be highly effective in solving few-shot learning tasks. However, extending the framework to many-shot scenarios, which may further enhance its practicality, has been relatively overlooked due to the technical difficulties of meta-learnin…

MetaPerturb: Transferable Regularizer for Heterogeneous Tasks and Architectures

NeurIPS 2020spotlight

Regularization and transfer learning are two popular techniques to enhance model generalization on unseen data, which is a fundamental problem of machine learning. Regularization techniques are versatile, as they are task- and architecture-agnostic, but they do not exploit a large amount of data ava…
