Researchers have proposed a new method called Random Slices Mixing Data Augmentation (RSMDA) for deep learning. RSMDA blends sections of images to create diverse training samples, overcoming the limitations of single-image-based methods. The strategy RSMDA(R), focusing on row-wise mixing, consistently outperformed existing techniques in reducing error rates and showcased robustness against adversarial attacks. RSMDA shows…
A recent study by researchers from the Harbin Institute of Technology and Huawei explores the issue of hallucinations in large language models (LLMs). LLMs have revolutionized natural language processing but have a tendency to generate information that seems credible but lacks factual basis. The study reclassifies hallucination types and proposes detection techniques to minimize their…
The RPRS model addresses the limitations of current search methods for long documents. It computes relevance between a query document and candidate documents based on proportional matches across their sentences. The approach consists of three stages: sentence encoding, finding the most relevant sentence sets, and proportion-based relevance scoring. The RPRS method significantly outperforms previous techniques…
Nvidia will delay the release of its H20 AI chip designed for the Chinese market until early 2024. The delay is a result of strategic challenges and compliance requirements, including integrating the chip into server infrastructure. The H20 chip aims to help Nvidia maintain its market share in China amid tighter export rules, as competitors…
Researchers have discovered new techniques for coaxing AI models into performing actions they are programmed to avoid. The study introduces “persona modulation,” a method where one AI model designs prompts to manipulate another model. By assuming a harmful persona and bypassing safety protocols, the target model’s rate of harmful outputs increased significantly. The research highlights…

NVIDIA has introduced the HELPSTEER dataset, a collection of annotated responses that influence helpfulness in language models. The dataset covers qualities such as accuracy, coherence, complexity, verbosity, and overall helpfulness. Researchers used the dataset to train the Llama 2 70B model, which outperformed other models on the MT Bench with a score of 7.54. The…
OpenAI, initially a non-profit, shifted to a for-profit structure in 2019, straying from its effective altruism mission. Effective altruism seeks to maximize positive impacts while long-termism focuses on reducing existential risks. OpenAI’s commercial expansion created a conflict between altruistic goals and practical business needs, leading to a clash of ideologies within the company. The recent…
