AlphaIntellect at SemEval-2024 Task 6: Detection of Hallucinations in Generated Text

One major issue in natural language generation (NLG) models is detecting hallucinations (semantically inaccurate outputs). This study investigates a hallucination detection system designed for three distinct NLG tasks: definition modeling, paraphrase generation, and machine translation. The system uses feedforward neural networks for classification and SentenceTransformer models for similarity scores and sentence embeddings. Even though the SemEval-2024 benchmark is showing good results, there is still room for improvement. Promising paths towards improving performance include considering multi-task learning methods, including strategies for handling out-of-domain data and minimizing bias, and investigating sophisticated architectures.
