An information theoretic approach to veridical hallucination
David Lewis, in "Veridical Hallucination and Prosthetic Vision", outlines his views on seeing. He discusses, by way of several examples, unusual visual conditions and gives explanations of why one does or does not see in those conditions. However, it is not always clear exactly how Lewis' views …

Mitigating LLM Hallucination in the Banking Domain
… examines existing strategies for mitigating LLM hallucinations and proposes a novel approach to reduce hallucinations in the context of predicting customer churn using LLMs.

The role of Attentional Binding in Hallucination Proneness
… evidence in healthy individuals with high hallucination proneness, particularly under tightly controlled visual tasks, remains limited. Aim: This thesis investigates how hallucination proneness affects early visual processing, attentional binding, and object categorisation as a function of …

Hallucination machine : a body centric model of space perception
… provide a body-centric computational model, The Hallucination Machine, that integrates bodily knowledge with senses in a common modality which I call "the sphere of embodiment". Understanding the human experience of space is an important inquiry not only in the context of design and architecture, …

"A journey is an hallucination" : Flann O'Brien's The Third Policeman
Flann O�Brien�s novel, The Third Policeman, consists of many unrealistic events, thus sharing similarities with the fantastic piece, Alice�s Adventures in Wonderland. The events and characters within the O�Brien�s storyline obtain no source of reason, and their actions and comments hold no sense of …

Eliminating Hallucination-Induced Errors in Code Generation with Functional Clustering
… a black-box wrapper that eliminates nearly all hallucination-induced errors while providing a tunable confidence score. The wrapper samples many candidate programs, executes each on a self-generated test suite, and clusters candidates whose I/O behavior is identical; the empirical mass of the …

EFFORTS TOWARD TRUSTWORTHY MACHINE LEARNING: MITIGATING OVERCONFIDENCE, HALLUCINATION, AND MODALITY BIAS
… to reliability issues such as overconfidence, hallucinations, and modality bias. This thesis addresses these challenges through post-hoc methods and targeted fine-tuning strategies. First, we mitigate overconfidence in discriminative models by introducing a neighborhood agreement metric that …

Utopic Déjà Vu: The Power of the Public Hallucination in the UAE
Every year, the United Arab Emirates processes millions of resident visas for those who chase the Dubai dream. In fact, the country has the largest migrant population per capita in the world. Much like Disney, Dubai brokers in feeding the imagination, chiefly of immigrant-workers who make up 90% of …

Spectral Geometry for Deep Learning: Compression and Hallucination Detection via Random Matrix Theory
… the other, their reliability is compromised by hallucinations and out-of-distribution errors, while their scale imposes severe efficiency and deployment barriers. This thesis develops a unifying spectral framework, grounded in Random Matrix Theory (RMT), to address both reliability and …

The interaction between auditory imagery vividness and auditory perception, and its application to hallucination proneness
… between auditory imagery vividness and hallucination proneness, and the influence of hallucination proneness on the interaction between imagery and perception (Chapters 4, 5 and 6). Imagery vividness differs according to sound category and familiarity and is affected by cues to imagine …

The nature of hallucinatory experience
… theories do not offer a satisfactory account of hallucination. Finally, I propose and defend a schematic version of a Kaplanian theory for perceptual experience that can arguably give a satisfactory account of the distinctive nature of hallucination. I compare my proposal with similar candidates …

Risk Factors for Visual Hallucinations in Parkinson's Disease: Investigating the Continuum
… neuropsychological aspects of visual hallucinations (VHs) in Parkinson's Disease (PD) and high proneness to VHs in the normal population. The aim of the thesis is to investigate whether the same risk factors are implicated in both hallucinating PD patients and in high-prone individuals …

Casting Protein Structure Predictors as Energy-Based Models for Binder Design and Scoring
Protein binder design has been transformed by hallucination-based methods that optimize structure prediction confidence metrics, such as the interface predicted TM-score (ipTM), via backpropagation. However, these metrics are imperfect proxies for binding affinity and do not reflect the statistical …

SMALL AND LARGE PERCEPTION MODELS FOR ROBOTIC NAVIGATION
… with transformers. To understand hallucinations and further improve model generalization and adaptability for navigation applications, we propose HallusionBench and AutoHallusion, the first few benchmarks designed to diagnose different types of hallucinations and systematically …

Beyond pre-training: continual learning and hallucinations in transformer-based language models.
… of recent approaches to detecting and mitigating hallucinations in large language models (LLMs) is conducted, identifying (1) a gap in how different LLM layers are used during detection and (2) the need for fine-grained detection between hallucinated and non-hallucinated responses to the same …
