The California Department of Corrections and Rehabilitation is reviewing hundreds of state parole hearings to see if any inmates who were denied parole were rejected because of faulty drug tests. Nearly 6,000 drug tests in California prisons are believed to have yielded false positives between April and July last year, and attorneys for the Board of Parole are now conducting a review of inmate files to determine if any of them need to appear before the parole board again to be reconsidered, according to officials with CDCR. If any inmates were denied parole because of the faulty tests, they could be owed a new hearing before the parole board, said attorneys representing inmates affected by the defective drug tests. The review is already underway and will determine if "without the positive drug screening, there is sufficient evidence to support an incarcerated person's denial of parole," said CDCR spokesperson Emily Humpal in a statement. If there isn't enough evidence to support incarceration other than the drug test, a new hearing will be scheduled.

Purpose: To assess the alignment of GPT-4-based evaluation to human clinician experts, for the evaluation of responses to ophthalmology-related patient queries generated by fine-tuned LLM chatbots. Methods: 400 ophthalmology questions and paired answers were created by ophthalmologists to represent commonly asked patient questions, divided into fine-tuning (368; 92%), and testing (40; 8%). We find-tuned 5 different LLMs, including LLAMA2-7b, LLAMA2-7b-Chat, LLAMA2-13b, and LLAMA2-13b-Chat. For the testing dataset, additional 8 glaucoma QnA pairs were included. 200 responses to the testing dataset were generated by 5 fine-tuned LLMs for evaluation. A customized clinical evaluation rubric was used to guide GPT-4 evaluation, grounded on clinical accuracy, relevance, patient safety, and ease of understanding. GPT-4 evaluation was then compared against ranking by 5 clinicians for clinical alignment. Results: Among all fine-tuned LLMs, GPT-3.5 scored the highest (87.1%), followed by LLAMA2-13b (80.9%), LLAMA2-13b-chat (75.5%), LLAMA2-7b-Chat (70%) and LLAMA2-7b (68.8%) based on the GPT-4 evaluation. GPT-4 evaluation demonstrated significant agreement with human clinician rankings, with Spearman and Kendall Tau correlation coefficients of 0.90 and 0.80 respectively; while correlation based on Cohen Kappa was more modest at 0.50. Notably, qualitative analysis and the glaucoma sub-analysis revealed clinical inaccuracies in the LLM-generated responses, which were appropriately identified by the GPT-4 evaluation. Conclusion: The notable clinical alignment of GPT-4 evaluation highlighted its potential to streamline the clinical evaluation of LLM chatbot responses to healthcare-related queries. By complementing the existing clinician-dependent manual grading, this efficient and automated evaluation could assist the validation of future developments in LLM applications for healthcare.

Biologists inspired by digital art generators like DALL-E decide to build artificial intelligence human proteins that can fight cancer, flu, and Covid. DALL-E works by processing the text descriptions through several layers of neural networks, which are sets of algorithms that are designed to mimic the way the human brain works. These neural networks analyze the text and extract a representation of the image that is described. This representation is then used to generate the new image, which is done by passing it through a decoder network. The decoder network then generates a new image that corresponds to the text description. One of the key features of DALL-E is its ability to generate images that are not present in the training dataset.

AI is transforming the practice of medicine. It's helping doctors diagnose patients more accurately, make predictions about patients' future health, and recommend better treatments. This Specialization will give you practical experience in applying machine learning to concrete problems in medicine. Medical treatment may impact patients differently based on their existing health conditions. In this third course, you'll recommend treatments more suited to individual patients using data from randomized control trials.

By Nilesh Jahagirdar Artificial Intelligence (AI) has been prevalent in almost every business sector. However, in recent years, technology has burst into the healthcare landscape, propelling innovations and showcasing the potential to support medical practitioners and patients. From early disease diagnosis, drug discovery and trials, and precision in patient monitoring to self-care, AI algorithms have augmented the expertise of healthcare providers. According to the stats – AI expenditure in India is estimated to reach $11.78 bn by 2025, expected to add $1 trillion to the Indian economy by 2035. The new-age technology is dominating the healthcare industry so much that it's being referred to as the new nervous system.

The death of a 33-year-old Sri Lankan migrant, trapped in the bowels of Japan's immigration system, triggered national calls to reform the bureaucracy that allowed her to waste away in a detention center without proper medical treatment. A government report Tuesday detailed the missteps that contributed to the tragedy, including insufficient medical resources, communication failures and a lack of proper oversight. But activists and politicians said the proposed changes did not go far enough to address the fundamental failures in an immigration system they describe as opaque and capricious. The nearly 280-page document describes the series of events that led to the death in March of Ratnayake Liyanage Wishma Sandamali, who had been detained for overstaying her visa. While the report said her death was the "result of illness," it noted the possibility that her health was affected by several factors, "making it difficult to concretely determine the cause."

Many large healthcare organizations are adopting RPA leading to digitalization which can lead to healthy competition between medical services. The use of disruptive science and technology can make the healthcare industry more efficient. In different industries, RPA is considered to be an exploratory step for enterprises and organizations to move into the world of artificial intelligence. According to the recent RPA report, increasing productivity and improving customer experience are the top priorities for organizations to adopt RPA. Currently, healthcare providers and professionals are looking for different ways to promote patient interaction, reduce costs, increase productivity, and increase operational efficiency.

As a long-time proponent of AI regulation that is designed to protect public health and safety while also promoting innovation, I believe Congress must not delay in enacting, on a bipartisan basis, Section 102(b) of The Artificial Intelligence Data Protection Act -- my proposed legislation and now a House of Representatives Discussion Draft Bill. Guardrails in the form of Section 102(b)'s ethical AI legislation are necessary to maintain the dignity of the individual. What does Section 102(b) of The AI Data Protection Act provide and why the urgent need for the federal government to enact it now? To answer these questions, it is first necessary to understand how artificial intelligence (AI) is being used during this historic moment when our democratic society is confronting two simultaneous existential threats. Only then can the risks that AI poses to our individual dignity be recognized, and Section 102(b) be understood as one of the most important remedies to protect the liberties that Americans hold dear and that serve as the bedrock of our society.

When Elon Musk and DARPA both hop aboard the cyborg hypetrain, you know brain-machine interfaces (BMIs) are about to achieve the impossible. BMIs, already the stuff of science fiction, facilitate crosstalk between biological wetware with external computers, turning human users into literal cyborgs. Yet mind-controlled robotic arms, microelectrode "nerve patches", or "memory Band-Aids" are still purely experimental medical treatments for those with nervous system impairments. With the Next-Generation Nonsurgical Neurotechnology (N3) program, DARPA is looking to expand BMIs to the military. This month, the project tapped six academic teams to engineer radically different BMIs to hook up machines to the brains of able-bodied soldiers.

The story that a Norwegian company has developed a scanner capable of recognising salmon by their faces (more specifically, "the distinct pattern of spots around their eyes, mouth and gills") and of identifying those with infections requiring medical treatment, is a perfect example of the potential AI has to change the modern workplace. AI evangelists (or prophets of doom, depending on your perspective) often predict that the technology will render human workers obsolete. In my view, the result of the growing adoption of AI will be a little less drastic, but no less significant. AI's great strength lies in analysing huge amounts of data and identifying patterns. It is a phenomenal tool for creating productivity gains, not simply by automating human work, but rather by giving humans the tools to apply far greater precision to their work.
