Twice Class Bias Correction for Imbalanced Semi-Supervised Learning

no code implementations27 Dec 2023 Lan Li, Bowen Tao, Lu Han, De-Chuan Zhan, Han-Jia Ye

Differing from traditional semi-supervised learning, class-imbalanced semi-supervised learning presents two distinct challenges: (1) The imbalanced distribution of training samples leads to model bias towards certain classes, and (2) the distribution of unlabeled samples is unknown and potentially distinct from that of labeled samples, which further contributes to class bias in the pseudo-labels during training.

Learning Robust Precipitation Forecaster by Temporal Frame Interpolation

On Pseudo-Labeling for Class-Mismatch Semi-Supervised Learning

no code implementations15 Jan 2023 Lu Han, Han-Jia Ye, De-Chuan Zhan

Based on the findings, we propose to improve PL in class-mismatched SSL with two components -- Re-balanced Pseudo-Labeling (RPL) and Semantic Exploration Clustering (SEC).

MotionInput v2.0 supporting DirectX: A modular library of open-source gesture-based machine learning and computer vision methods for interacting and controlling existing software with a webcam

no code implementations10 Aug 2021 Ashild Kummen, Guanlin Li, Ali Hassan, Teodora Ganeva, Qianying Lu, Robert Shaw, Chenuka Ratwatte, Yang Zou, Lu Han, Emil Almazov, Sheena Visram, Andrew Taylor, Neil J Sebire, Lee Stott, Yvonne Rogers, Graham Roberts, Dean Mohamedally

We also introduce a series of bespoke gesture recognition classifications as DirectInput triggers, including gestures for idle states, auto calibration, depth capture from a 2D RGB webcam stream and tracking of facial motions such as mouth motions, winking, and head direction with rotation.

Revisiting Unsupervised Meta-Learning via the Characteristics of Few-Shot Tasks

1 code implementation30 Nov 2020 Han-Jia Ye, Lu Han, De-Chuan Zhan

Meta-learning has become a practical approach towards few-shot image classification, where "a strategy to learn a classifier" is meta-learned on labeled base classes and can be applied to tasks with novel classes.
