Balancing Bias and Variance for Active Weakly Supervised Learning

1 code implementation12 Jun 2022 Hitesh Sapkota, Qi Yu

We propose to conduct novel active deep multiple instance learning that samples a small subset of informative instances for annotation, aiming to significantly boost the instance-level prediction.

Bayesian Nonparametric Submodular Video Partition for Robust Anomaly Detection

1 code implementation CVPR 2022 Hitesh Sapkota, Qi Yu

BN-SVP essentially performs dynamic non-parametric hierarchical clustering with an enhanced self-transition that groups segments in a video into temporally consistent and semantically coherent hidden states that can be naturally interpreted as scenes.

Distributionally Robust Optimization for Deep Kernel Multiple Instance Learning

1 code implementation AISTATS 2021 Hitesh Sapkota, Qi Yu

However, solely focusing on a single instance in a bag makes the model less robust to outliers or multi-modal scenarios, where a single bag contains a diverse set of positive instances.
