Supervised Cross-Subject Adaptation and Low-Latency Confidence-Aware Trie Decoding for EEG-Based Imagined Handwriting Recognition
This paper presents a framework for EEG-based imagined handwriting recognition that combines a frozen cross-subject neural encoder with a lightweight target-specific classifier and a confidence-aware trie decoder to achieve rapid personalization, high word-reconstruction accuracy, and low-latency energy-efficient performance on edge devices.
