My doctoral research summary:
Large language models often exhibit hallucinations and misinformation through the generated texts. Typically, most LLM-based chat agents cannot grasp changing contexts and topics to deliver expected responses with natural semantics. The knowledge represented by the language models is often non-dynamic or backdated, too. Also, there are very few LLMs as of now, optimized for the low-resource Indo-Aryan languages, especially Bengali, to represent local social thematic representations, conversational contexts, and exploring applications in various domains. My doctoral research exists in these broad areas to counter these issues and unify them to aim toward efficient language generation.
