FANTF: Fuzzy attention network based transformers for time series analysis

Read the original on arXiv Machine Learning →

The paper presents FANTF, a Fuzzy Attention Network-Based Transformer that integrates fuzzy logic into transformer architectures via a novel fuzzy attention mechanism inspired by Type‑2 fuzzy set theory. This mechanism employs a learnable Gaussian uncertainty perturbation to model uncertainty in attention relevance scores, producing softer, more diverse attention distributions and uncertainty‑aware interpretations. Experiments across five transformer backbones on real‑life datasets show statistically significant improvements in forecasting, classification, and anomaly detection, especially under noisy and non‑stationary conditions.

Fewer yet critical: Reducing Redundant Token Dependencies for Transformer-based Time Series Forecasting

The paper introduces a token dependency selection strategy for Transformer-based time series forecasting. By jointly applying an attention entropy constraint and a prediction error constraint, the method identifies fewer but more critical inter-token dependencies, reducing the influence of redundant dependencies that can hurt generalization. Experiments on multiple datasets show that this approach improves forecasting performance across various Transformer models.

SETTer: Sparse-Encoder Transformer for Long-term Multivariate Time Series Forecasting

SETTer is a transformer-based model designed for long‑term multivariate time‑series forecasting. It introduces decoupled self‑attention and hybrid masking to better handle high dimensionality and complex relationships, while adding explainable structures to highlight discriminative patterns. Experiments on real‑world benchmarks show that SETTer outperforms state‑of‑the‑art models in 88% of scenarios.

A Lightweight Plug-in Gate for Transformer-Based Time-Series Forecasters

The paper introduces a lightweight pre‑encoder gate for Transformer‑based time‑series forecasters, which assigns sigmoid scores to covariate representations before they enter the encoder. The gate is evaluated as a plug‑in for models such as TimeXer, iTransformer, and PatchTST on datasets including ETTm1, ETTm2, Traffic, Energy, and ILI, showing competitive performance and the ability to regulate covariate admission via a usage penalty. Experiments also explore gate placement, initialization, and feature importance using VIF‑informed permutation diagnostics.

SETTer: Sparse-Encoder Transformer for Long-term Multivariate Time Series Forecasting

SETTer is a transformer-based model designed for long‑term multivariate time‑series forecasting. It introduces decoupled self‑attention and hybrid masking to better capture short‑ and long‑term patterns across time and channel dimensions, while adding simple explainable structures to highlight discriminative patterns. Experiments on real‑world benchmarks show that a single‑layer SETTer outperforms state‑of‑the‑art models in 88% of scenarios.
