The field of natural language processing is witnessing significant developments in domain adaptation and continual learning for large language models. Researchers are exploring innovative approaches to adapt these models to specialized domains and tasks, while preserving their robust semantic discrimination properties. One notable direction is the use of multi-stage frameworks that incorporate joint domain-specific masked supervision and contrastive objectives. Another area of focus is the development of novel mechanisms for dynamic modulation of representations, enabling more effective and efficient adaptation to multiple tasks. Furthermore, there is a growing interest in collaborative frameworks that leverage small models to assist large models, reducing computational resource consumption while maintaining comparable accuracy. Noteworthy papers in this regard include MOSAIC, which introduces a multi-stage framework for domain adaptation of sentence embedding models, and Localist LLMs with Recruitment Learning, which presents a novel framework for training large language models with continuously adjustable internal representations. Additionally, Contextual Attention Modulation and KORE are also making significant contributions to the field by proposing novel mechanisms for efficient multi-task adaptation and knowledge injection in large language models.
