Exploring and Evaluating Hallucinations in LLM-Powered Code Generation

arXiv.org
The rise of Large Language Models (LLMs) has significantly advanced many applications on software engineering tasks, particularly in code generation. Despite the promising performance, LLMs are prone to generate hallucinations, which means LLMs might ...

Mitigating Hallucinations in Large Vision-Language Models with Instruction Contrastive Decoding

Annual Meeting of the Association for Computational Linguistics
Large Vision-Language Models (LVLMs) are increasingly adept at generating contextually detailed and coherent responses from visual inputs. However, their application in multimodal decision-making and open-ended generation is hindered by a notable rate of

Hallucinations in LLMs: Understanding and Addressing Challenges

International Convention on Information and Communication Technology, Electronics and Microelectronics
Large language models (LLM) are trained to understand and generate human-like language. While LLMs present a cutting-edge concept and their use is becoming widespread, hallucinations sometimes occur during their operation.

Hallucinations

Perceptual and Motor Skills, 1998
Hallucinations, sensory perceptions without environmental stimuli, occur as simple experiences of auditory, gustatory, olfactory, tactile, or visual phenomena as well as mixed or complex experiences of more than one simple phenomenon. The nature of the hallucination assists localization, differential diagnosis, and treatment planning.

Lookback Lens: Detecting and Mitigating Contextual Hallucinations in Large Language Models Using Only Attention Maps

Conference on Empirical Methods in Natural Language Processing
When asked to summarize articles or answer questions given a passage, large language models (LLMs) can hallucinate details and respond with unsubstantiated answers that are inaccurate with respect to the input context.

Musical Hallucinations

Current Psychiatry Reports, 2006
Musical hallucinations have been described in numerous neurologic and psychiatric patients, but their pathophysiologic background is not understood. Analyzing the published cases, five subgroups can be separated according to their etiology: hypacusis, psychiatric disorders, focal brain lesions, epilepsy, and intoxication.

Minor hallucinations reflect early gray matter loss and predict subjective cognitive decline in Parkinson's disease

European Journal of Neurology, 2020
Well‐structured hallucinations in Parkinson’s disease (PD) are associated with poor prognosis and dementia. However, the predictive value of minor psychotic phenomena in cognitive deterioration is not well known.

The predisposition to hallucinate

Psychological Medicine, 1980
SYNOPSISIt is argued that people who are predisposed to mistake a vivid imagination image for a genuine percept (i.e. hallucinators) should show an impaired ability to make clear perceptual–conceptual distinctions (i.e. boundary confusion) and should lack familiarity with internal sources of information.

Hallucinations in schizophrenia

Acta Psychiatrica Scandinavica, 1990
ABSTRACTThe prevalence of different types of hallucinations and their clinical correlates were examined in 117 DSM‐III‐R schizophrenic or schizoaffective disorder patients. Auditory hallucinations were by far the most common, followed by visual hallucinations, and then by tactile and olfactory or gustatory hallucinations.
