FAME: Forecastability-Aware Mixture of Experts for Heterogeneous Time Series Forecasting

arXiv:2606.08896v1 Announce Type: new Abstract: Large-scale retail and industrial forecasting systems contain many heterogeneous time series whose lifecycle, sparsity, volatility, seasonality, spectral patterns, and contextual sensitivity differ substantially. A single forecasting model rarely performs well across all regimes, while dense ensembles increase inference cost and provide limited insight into expert suitability. This paper studies forecastability-aware expert routing: learning how data characteristics determine the suitability of forecasting experts. We propose \method{}, a sparse

Why this matters
Why now

The increasing complexity and scale of real-world AI applications, especially in areas like retail and industry, demand more sophisticated and efficient forecasting models capable of handling heterogeneous data.

Why it’s important

This research addresses a critical challenge in AI: improving the accuracy and efficiency of forecasting systems across diverse and complex datasets, which is fundamental for optimizing operations in various sectors.

What changes

Traditional monolithic forecasting models or dense ensembles will be increasingly replaced by more intelligent, 'forecastability-aware' systems that dynamically select or combine expert models, leading to better decision-making and resource allocation.

Winners
  • · Retail and e-commerce companies
  • · Industrial manufacturers
  • · Logistics and supply chain management
  • · Machine learning researchers and developers
Losers
  • · Companies relying on single, static forecasting models
  • · Inefficient AI systems with high inference costs
Second-order effects
Direct

Forecasting systems become more accurate and computationally efficient in heterogeneous environments.

Second

Improved forecasting leads to optimized inventory management, reduced waste, and more agile operational planning for large enterprises.

Third

The enhanced capability for AI to handle diverse real-world data patterns could accelerate automation in new sectors, impacting labor markets and operational structures.
