We present a novel framework for hallucinating faces of unconstrained poses and with very low resolution (face size as small as 5pxIOD). In contrast to existing studies that mostly ignore or assume pre-aligned face spatial configuration (e.g. facial landmarks localization or dense correspondence field), we alternatingly optimize two complementary tasks, namely face hallucination and dense corre...

Abstract The goal of information-seeking dialogue is to respond seeker queries with natural language utterances that are grounded on knowledge sources. However, systems often produce unsupported utterances, a phenomenon known as hallucination. To mitigate this behavior, we adopt data-centric solution and create FaithDial, new benchmark for hallucination-free dialogues, by editing hallucinated r...

We are reporting a case of zolpidem induced multimodal hallucinations in a 22 year old female without any history of psychiatric disorders. Zolpidem, by acting on gamma-amino butyric acid type A receptor has a potential to cause a paradoxical reaction and there also exists a possibility of an induced delirium with its use. This case reports evaluates its potential to cause multimodal hallucinat...

Topiramate (TPM) is an antiepileptic drug also used in migraine prophylaxis (Silberstein et al. 2007). Neuropsychiatric symptoms may emerge during the use of TPM (Fröscher et al. 2005). There are few reports showing a link between psychotic adverse events and use of TPM (Khan et al. 1999). Only one patient with schizoaffective disorder has been reported in the litera ture, who complained of dos...

We study stochastic control problems in the presence of hard wall constraints. Walls are incorporated in the dynamics of the agent by restricting its domain and hence perturbing the noise process close to the walls. A novel penalty term is introduced for bouncing off a wall. To efficiently search for a good policy we propose the “hallucination expectation maximization” algorithm which iterative...

The concept of conversion hallucination is a relatively new one, however there have been several articles written on this phenomena, some attesting to it being a special form of hallucination while others dismissing it altogether. But currently this concept is slowly being accepted among psychiatrists and as such it is important for us to understand some of the concepts. In this case report, th...

OBJECTIVES Between 8% and 40% of patients with Parkinson's disease undergoing long term treatment will have visual hallucinations during the course of their illness. There were two main objectives: firstly, to review the literature on Parkinson's disease and summarise those factors most often associated with hallucinations; secondly, to carry out a clinical comparison of ambulant patients with ...
