Alignment Supervision

Alignment supervision in machine learning aims to improve model training by incorporating information about the correspondence between input data and target labels, often leveraging weaker forms of supervision than fully annotated data. Current research focuses on using pre-trained models or auxiliary tasks to generate these alignments, employing techniques like label smoothing and cross-entropy losses applied at various model layers, sometimes within transformer or graph-based architectures. This approach shows promise in enhancing the performance of various tasks, including automatic speech recognition and semantic parsing, by improving generalization and reducing the need for extensive manual annotation. The resulting improvements in accuracy and efficiency have significant implications for data-intensive applications across multiple domains.
