Beyond the Benchmark: Rethinking Deep Learning for Time Series

30.12.2025 by qfx

Forecasting models-excluding spatial processing-demonstrate performance, quantified by mean squared error (MSE) and mean absolute error (MAE), over a 96-step horizon, with the most effective configurations distinguished by bolded values and the second most effective underlined.

A critical look at how we evaluate deep learning models reveals that inconsistent practices are obscuring real progress in time series forecasting.

Pricing for Platforms: From Confusion to Optimal Fees

30.12.2025 by qfx

The comparative analysis of ride-hailing transaction records from February and March 2024 within the same urban environment demonstrates a temporal shift in service utilization, evidenced by a singular receipt from the earlier month contrasted with a pair from the latter, suggesting an increased demand-or potentially, increased ride frequency-during March.

New research reveals how third-party platforms can dynamically adjust service fees to maximize learning and minimize regret in the face of uncertain demand.

Forging Quality Control: Synthetic Images Sharpen Anomaly Detection

30.12.2025 by qfx

A novel training strategy sequentially leverages rule-based and generative image synthesis-beginning with large-scale rule-based pre-training and culminating in fine-tuning with a targeted anomaly synthesis framework-to enhance data quality, where the framework employs a text-guided image-to-image translation model and an image retrieval model to generate and filter synthetic anomalies based on textual defect descriptions and visual similarity to normal images.

A new approach uses the power of generative AI to create realistic defect images, significantly improving the accuracy and efficiency of industrial inspection systems.
