RefineBridge: Generative Bridge Models Improve Financial Forecasting by Foundation Models
Anthony Bolton, Wuyang Zhou, Zehua Chen +2
Financial time series forecasting is particularly challenging for transformer-based time series foundation models (TSFMs) due to non-stationarity, heavy-tailed distributions, and h…
Exploiting the Prior of Generative Time Series Imputation
YuYang Miao, Chang Li, Zehua Chen
Time series imputation, i.e., filling the missing values of a time recording, finds various applications in electricity, finance, and weather modelling. Previous methods have intro…
RespDiff: An End-to-End Multi-scale RNN Diffusion Model for Respiratory Waveform Estimation from PPG Signals
Yuyang Miao, Zehua Chen, Chang Li +1
Respiratory rate (RR) is a critical health indicator often monitored under inconvenient scenarios, limiting its practicality for continuous monitoring. Photoplethysmography (PPG) s…
Improving Diffusion Models for ECG Imputation with an Augmented Template Prior
Alexander Jenkins, Zehua Chen, Fu Siong Ng +1
Pulsative signals such as the electrocardiogram (ECG) are extensively collected as part of routine clinical care. However, noisy and poor-quality recordings are a major issue for s…
