Orthogonal Representation Editing: Decoupling Semantic Entanglement in Batch Knowledge Editing of LLMs

Wenhao Yu, Zhicong Lu, Bo Lv +4

Knowledge editing aims to efficiently update factual information in Large Language Models (LLMs) without full retraining. However, existing methods still suffer from performance de…

Beyond Similarity: Temporal Operator Attention for Time Series Analysis

Jevon Twitty, Vinh Pham, Nitiwith Rotchanarak +4

A persistent paradox in time-series forecasting is that structurally simple MLP and linear models often outperform high-capacity Transformers. We argue that this gap arises from a…

HyperMLP: An Integrated Perspective for Sequence Modeling

Jiecheng Lu, Shihao Yang

Self-attention is often viewed as probabilistic query-key lookup, motivating designs that preserve normalized attention scores and fixed positional semantics. We advocate a simpler…

StretchTime: Adaptive Time Series Forecasting via Symplectic Attention

Yubin Kim, Viresh Pati, Jevon Twitty +3

Transformer architectures have established strong baselines in time series forecasting, yet they typically rely on positional encodings that assume uniform, index-based temporal pr…

Free Energy Mixer

Jiecheng Lu, Shihao Yang

Standard attention stores keys/values losslessly but reads them via a per-head convex average, blocking channel-wise selection. We propose the Free Energy Mixer (FEM): a free-energ…

WAVE: Weighted Autoregressive Varying Gate for Time Series Forecasting

Jiecheng Lu, Xu Han, Yan Sun +1

We propose a Weighted Autoregressive Varying gatE (WAVE) attention mechanism equipped with both Autoregressive (AR) and Moving-average (MA) components. It can adapt to various atte…
