Bayesian Random Semantic Data Augmentation for Medical Image Classification

1 code implementation10 Mar 2024 Yaoyao Zhu, Xiuding Cai, Xueyao Wang, Yu Yao

However, these approaches encounter notable limitations: image transformation-based and automated data augmentation techniques cannot implement semantic transformations, leading to a constrained variety of augmented samples, and generative data augmentation methods are computationally expensive.

HyperLips: Hyper Control Lips with High Resolution Decoder for Talking Face Generation

1 code implementation9 Oct 2023 Yaosen Chen, Yu Yao, Zhiqiang Li, Wei Wang, Yanru Zhang, Han Yang, Xuming Wen

First, FaceEncoder is used to obtain latent code by extracting features from the visual face information taken from the video source containing the face frame. Then, HyperConv, which weighting parameters are updated by HyperNet with the audio features as input, will modify the latent code to synchronize the lip movement with the audio.

Emulating Quantum Dynamics with Neural Networks via Knowledge Distillation

1 code implementation19 Mar 2022 Yu Yao, Chao Cao, Stephan Haas, Mahak Agarwal, Divyam Khanna, Marcin Abram

We focus on the question of how the emulator learns the rules of quantum dynamics from the curriculum of simple training examples and to which extent it can generalize the acquired knowledge to solve more challenging cases.

Can Label-Noise Transition Matrix Help to Improve Sample Selection and Label Correction?

no code implementations29 Sep 2021 Yu Yao, Xuefeng Li, Tongliang Liu, Alan Blair, Mingming Gong, Bo Han, Gang Niu, Masashi Sugiyama

Existing methods for learning with noisy labels can be generally divided into two categories: (1) sample selection and label correction based on the memorization effect of neural networks; (2) loss correction with the transition matrix.

Instance-dependent Label-noise Learning under a Structural Causal Model

2 code implementations NeurIPS 2021 Yu Yao, Tongliang Liu, Mingming Gong, Bo Han, Gang Niu, Kun Zhang

In particular, we show that properly modeling the instances will contribute to the identifiability of the label noise transition matrix and thus lead to a better classifier.

Coupling Intent and Action for Pedestrian Crossing Behavior Prediction

1 code implementation10 May 2021 Yu Yao, Ella Atkins, Matthew Johnson Roberson, Ram Vasudevan, Xiaoxiao Du

In this work, we follow the neuroscience and psychological literature to define pedestrian crossing behavior as a combination of an unobserved inner will (a probabilistic representation of binary intent of crossing vs. not crossing) and a set of multi-class actions (e. g., walking, standing, etc.).

Markov chain Monte Carlo methods for hierarchical clustering of dynamic causal models

no code implementations10 Dec 2020 Yu Yao, Klaas E. Stephan

Specifically, we introduce a class of proposal distributions which aims to capture the interdependencies between the parameters of the clustering and subject-wise generative models and helps to reduce random walk behaviour of the MCMC scheme.
