Beyond Immediate Activation: Temporally Decoupled Backdoor Attacks on Time Series Forecasting

AAAI 2026technical

Existing backdoor attacks on multivariate time series (MTS) forecasting enforce strict temporal and dimensional coupling between triggers and target patterns, requiring synchronous activation at fixed positions across variables. However, realistic scenarios often demand delayed and variable-specific

Convergence of Online Learning Algorithm for a Mixture of Multiple Linear Regressions

ICML 2024poster

This paper considers the parameter learning and data clustering problem for MLR with multiple sub-models and arbitrary mixing weights. To deal with the data streaming case, we propose an online learning algorithm to estimate the unknown parameters. By utilizing Ljung's ODE method, we establish the a…
