Beyond Model Ranking: Predictability-Aligned Evaluation for Time Series Forecasting

ICML 2026poster

In the era of increasingly complex AI models for time series forecasting, progress is often measured by marginal improvements on benchmark leaderboards. However, standard evaluations rely on aggregate metrics (e.g., MSE) that conflate model capability with the intrinsic difficulty of the evaluated i…

Efficient Parallel Training Methods for Spiking Neural Networks with Constant Time Complexity

ICML 2025poster

Spiking Neural Networks (SNNs) often suffer from high time complexity $O(T)$ due to the sequential processing of $T$ spikes, making training computationally expensive. In this paper, we propose a novel Fixed-point Parallel Training (FPT) method to accelerate SNN training without modifying the netwo…

TS-LIF: A Temporal Segment Spiking Neuron Network for Time Series Forecasting

ICLR 2025poster

Spiking Neural Networks (SNNs) offer a promising, biologically inspired approach for processing spatiotemporal data, particularly for time series forecasting. However, conventional neuron models like the Leaky Integrate-and-Fire (LIF) struggle to capture long-term dependencies and effectively proces…
