Despite being almost a year old, this blog by Chip Huyen is still a great read for getting into fine-tuning LLMs.
This article covers everything you need to know about Reinforcement Learning from Human Feedback (RLHF).

Earlier this month, a sudden atmospheric warming event caused the Arctic’s polar vortex to reverse its trajectory. The swirling ring of cold air is now spinning in the wrong direction, which has triggered a record-breaking “ozone spike” and could impact global weather patterns.
New research suggests that there is no ‘typical’ form of Alzheimer’s disease, as the condition can manifest in at least four different ways.
Andreas Mogensen was impressed by how smooth a landing it was.
The first European Space Agency (ESA) astronaut (and first non-American) to serve as a pilot on a U.S. commercial crew spacecraft, Mogensen and his SpaceX Crew-7 crewmates returned to Earth after a 197-day stay aboard the International Space Station (ISS) on March 12.
The AI firm will preview the tool with early testers but won’t release it widely because of the potential for misuse ahead of the election.
New research from scientists at the Wu Tsai Neurosciences Institute at Stanford University has identified a key driver of myelination, the formation of protective fatty sheaths around nerve fibers.
In a Leicester study that looked at whether artificial intelligence (AI) can be used to predict whether a person was at risk of a lethal heart rhythm, an AI tool correctly identified the condition 80 per cent of the time.
The findings of the study, led by Dr Joseph Barker working with Professor Andre Ng, Professor of Cardiac Electrophysiology and Head of Department of Cardiovascular Sciences at the University of Leicester and Consultant Cardiologist at the University Hospitals of Leicester NHS Trust, have been published in the European Heart Journal-Digital Health.
Ventricular arrhythmia (VA) is a heart rhythm disturbance originating from the bottom chambers (ventricles) where the heart beats so fast that blood pressure drops which can rapidly lead to loss of consciousness and sudden death if not treated immediately.
Portable AI-powered devices that connect directly to a chatbot without the need for apps or a touchscreen are set to hit the market. Are they the emperor’s new clothes or a gamechanger?
Autoimmune diseases pose significant challenges in healthcare, affecting millions worldwide. Recent research has suggested a potential link between gut microbiota and autoimmune conditions, paving the way for innovative therapeutic approaches. A study published in BMC Medicine aimed to systematically review the efficacy of probiotic therapy in managing various autoimmune diseases. The study was conducted by Zeng L. and colleagues.
Autoimmune diseases, including fibromyalgia, psoriasis, juvenile idiopathic arthritis (JIA), lupus nephritis, systemic lupus erythematosus, ulcerative colitis, and Crohn’s disease, result from dysregulation of the immune system. Genetic, environmental, and microbial factors, particularly gut microbiota, are implicated in their pathogenesis. Probiotics, defined as beneficial microorganisms that colonize the gut and modulate host immunity and metabolism, offer a promising avenue for treatment.
The study conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) evaluating the efficacy of probiotic therapy in autoimmune diseases. Researchers searched multiple databases for eligible trials up to June 2022 and assessed outcomes such as Disease Activity Score at 28 joints (DAS28), Psoriasis Area and Severity Index (PASI), and Systemic Lupus Erythematosus Disease Activity Measure (SLEDAI).
The problem with just leaving poop on the highest peak in the world is that the environ’s extremely cold temperatures are not at all conducive to degrading biological matter. In addition, poop runoff is a problem at lower elevations — to the degree that they’ve contaminated the local watershed.
Basically, Mount Everest is covered in human feces. It’s a problem that hikers, sherpas and local officials have been complaining about for years.
But now, according to CNN, new poop rules are in place. If you want to climb Mount Everest from Nepal, the most common entryway, you gotta take your crap back with you instead of leaving it on the mountain.
