This paper explores the dual role of Large Language Models (LLMs) in context online misinformation and disinformation. In today's digital landscape, where internet social media facilitate rapid dissemination information, discerning between accurate content falsified information presents a formidable challenge. Misinformation, often arising unintentionally, disinformation, crafted deliberately, are at forefront this LLMs such as OpenAI's GPT-4, equipped with advanced language generation...

Alzheimer's disease (AD) is a neurodegenerative disorder resulting in memory loss and cognitive decline caused due to the death of brain cells. It most common form dementia accounts for 60-80% all cases. There no single test diagnosis AD, doctors rely on medical history, neuropsychological assessments, computed tomography (CT) or magnetic resonance imaging (MRI) scan brain, etc. confirm diagnosis. In terms treatment, currently, there neither cure nor any way slow progression AD. However,...

With growing number of ageing population, Parkinson's disease has become a serious problem to huge fraction people above 60. The severely affects the motor system and can lead death patients. There is no cure available for disease. symptoms on seen very late which leads into difficulty in management makes it more difficult when diagnosed later. For early stages disease, there are some medications improve symptoms. certain like slurred speech, problems utterances, etc. earlier. These be...

Text-embedded images are frequently used on social media to convey opinions and emotions, but they can also be a medium for disseminating hate speech, propaganda, extremist ideologies. During the Russia-Ukraine war, both sides text-embedded extensively spread propaganda speech. To aid in moderating such content, this paper introduces CrisisHateMM, novel multimodal dataset of over 4,700 from conflict, annotated non-hate The speech is directed undirected with further individual, community,...

The digitization of healthcare systems has led to the proliferation electronic health records (EHRs), serving as comprehensive repositories patient information. However, vast volume and complexity EHR data present challenges in extracting meaningful insights. This paper addresses need for automated analysis EHRs by proposing a novel graph learning model with label attention (GLLA) temporal event prediction. GLLA utilizes neural networks capture intricate relationships between medical codes...

In the ever-evolving landscape of online discourse and political dialogue, rise hate speech poses a significant challenge to maintaining respectful inclusive digital environment. The context becomes particularly complex when considering Hindi language—a low-resource language with limited available data. To address this pressing concern, we introduce CHUNAV dataset—a collection 11,457 tweets gathered during assembly elections in various states. is purpose-built for categorization...

Fine-tuning large pre-trained models for downstream tasks can be really expensive.In the past, researchers have proposed various alternatives like adapter and prompt-based methods tuning these language using minimal parameters.However, applying prompt-tuning smaller has not been effective so far much work is done in pushing forward soft prompting models.To improve training efficiency of reduce size tuned parameters, we propose a novel Adapter-based Efficient Prompt Tuning approach (ADEPT).In...

Study of the ionosphere is important for research in various domains. Especially communication systems, this study holds a great importance. In ionospheric research, there need to delineate useful and non-useful radar returns from ionosphere. The can be used further analysis discarded. When usefulness analyzed by humans, it simply time-consuming prone more human errors. Thus, some machine learning methods are needed returns. algorithms (classical ensemble learners) as well deep models tested...

Alzheimer's Disease (AD) is one of the most common forms neuropsychological disorder in elderly people. It a slow progressive disease affecting brain cells. This affects cognitive abilities people and their daily activities. During course disease, memory gets brutally affected too. Working as well long-term declarative deteriorates AD patients. Due to this deterioration memory, patients tend show decline communicative skills well. reflected speech. usually have poor grammar along with very...
