A sociologist highlights the ethical implications of machine learning in healthcare, criticizing United Healthcare’s use of AI to prematurely discharge patients, focused on cost savings rather than patient care. The AI model, influenced by economic incentives, risks life and quality of life, leading to unethical healthcare decisions and potential malpractice by ignoring doctors’ expertise.
Instead of fully retraining large language models (LLMs) for different tasks, LoRA adapters can be fine-tuned, allowing cost-effective task-specific adaptations. A novel approach described in the article enables combining multiple LoRA adapters to create a versatile adapter for multitasking, such as both chatting and translating, using a single LLM with a simple process of weighted…

Collaborations, customer engagement, and new tools like Guardrails and Model Evaluation on Amazon Bedrock enable safe scaling of AI, embedding safeguards against disinformation and…
The {dplyr} package in R is designed for data manipulation, offering functions to filter, sort, and summarize data. One can group data, count distinct values, and strategically create or modify variables with “if else” or “case when” conditions. The package’s ease of use and code readability are highlighted, and chaining operations is efficient with the…
A data scientist’s guide to combating category size bias: size doesn’t necessarily correlate with quality or performance. Small models can be effective, accuracy can mask class imbalance, larger datasets don’t always improve predictions, and longer algorithms aren’t inherently better. Awareness and questioning assumptions can mitigate bias.
Stability AI, the company behind Stable Diffusion, is considering a sale amidst investor unrest and financial woes. CEO Emad Mostaque’s leadership has been questioned by investors, including Coatue Management, leading to tensions. Despite releasing impressive tech and achieving unicorn status in 2022, the firm’s high expenses over revenue raise sustainability concerns.
DeepMind’s AI GNoME predicts over 2 million new materials, revolutionizing discovery with deep-learning models and autonomous laboratory A-Lab, enhancing synthesis efficiency and potential applications in various high-tech fields, outlined in a Nature-published study.
The AWS Generative AI Innovation Center, launched in June 2023, has assisted numerous clients in creating custom AI solutions.
