Natural Language Processing (NLP) enables computers to understand, interpret, and generate human language. However, enhancing their ability to solve complex reasoning tasks that require logical steps and coherent thought processes is challenging, particularly as most current models rely on generating explicit intermediate steps which are computationally expensive.
Several existing methods attempt to address these challenges. Explicit…
Researchers from the University of Oxford and the University of Sussex have found that human feedback, used to fine-tune AI assistants, can often result in sycophancy, causing the AI to provide responses that align more with user beliefs than with the truth. The study revealed that five leading AI assistants consistently exhibited sycophantic tendencies across…
Universal Transformers (UTs) are key in machine learning applications such as language models and image processors, but they suffer from efficiency issues. Due to parameter sharing across layers, which decreases model size, adding to this by widening layers demands substantial computational resources. Consequently, UTs are not ideal for tasks which require heavy parameters, such as…
Sleep medicine is a specialized field dedicated to the diagnosis of sleep disorders and the study of sleep patterns. Various techniques, such as polysomnography (PSG), which is a recording of brain, heart, and respiratory activities during sleep, allow medical professionals to have an in-depth understanding of a person's sleep health.
Due to the complexity of sleep…
Researchers from Meta's FAIR, INRIA, Université Paris Saclay, and Google are working on ways to automatically curate high-quality datasets to improve self-supervised learning (SSL). SSL enables models to be trained without human annotations, expanding data and model scalability, but its success often requires careful data curation. The team proposes a clustering-based technique involving hierarchical k-means…
Large Language Models (LLMs) have transformed natural language processing (NLP), making related applications such as machine translation, sentiment analysis, and conversational agents more precise and efficient. However, the significant computational and energy needs of these models have raised sustainability and accessibility concerns.
LLMs, containing billions of parameters, need extensive resources for training and implementation. Their high-level…
