As LLMs integrate into our daily lives, understanding their behavior becomes essential. In our ongoing efforts to study model behavior and alignment, we present this work as an early step in that direction. We focus on behavioral dispositions — the underlying tendencies that shape responses in social contexts — and introduce a framework to study how closely the dispositions expressed by LLMs align with those of humans.Behavioral dispositions are typically quantified via self-report questionnaires under different traits (e.g., empathy, assertiveness), where individuals rate their agreement with preference-statements, such as, “I am quick to express an opinion.” The questionnaires used in…

A loss function is what guides a model during training, translating predictions into a signal it can improve on. But not all losses behave the same—some amplify large errors, others stay stable in noisy settings, and each choice subtly shapes how learning unfolds. Modern libraries add another layer with reduction modes and scaling effects that influence optimization. In this article, we break down the major loss families and how to choose the right one for your task.  Mathematical Foundations of Loss Functions In supervised learning, the objective is typically to minimize the empirical risk,  (often with optional sample weights and…

March was an incredible month for the Cisco Meraki developer community. Every Thursday, we released a new video dedicated to showcasing how you can leverage the Meraki platform to build smarter, more automated, and highly observable networks. If you missed any of the sessions, here is a recap of our five-part series on the tools and protocols that are shaping the future of cloud-managed IT. Episode 1: Meraki OAuth We kicked off the month with Oren Brigg, who demystified OAuth and explained how to implement this open standard authorization protocol within the Meraki dashboard. As we transition away from traditional…

A Nigerian man who posed as a woman online to swindle men out of their savings has been sentenced to 15 years in a US prison. And in a surprising twist, it turns out that he was caught out after accidentally trying to swindle a fellow fraudster.35-year-old Saheed Sunday Owolabi was sentenced after a jury trial in Wilmington, North Carolina, which saw him convicted of conspiracy to commit wire fraud and money laundering.According to evidence presented at the trial, Owolabi would pretend to be a woman online to build relationships with men across the United States. He and his fellow…

Support CleanTechnica’s work through a Substack subscription or on Stripe. In response to rising petrol and diesel costs and the uncertainty of where they will peak, March has seen a surge in Electric Vehicle sales across Australia and New Zealand. Reports of rapidly increasing search numbers — doubling each week — according to reports in the main stream media led me to investigate further. Now I am hearing of car sale yards being emptied of any sort of electrified vehicle and waiting lists growing longer. Prices for second hand EVs have also increased. Dealers have been warned not to sell…

Hadlee Simons / Android AuthorityWearables have come a long way from just counting steps. These days, they’re feature-packed wellness companions, tracking us through everything from sweaty workouts to abbreviated REM cycles. For a lot of shoppers, the idea of a daily health hub is the whole point. It’s also exactly why Samsung’s approach feels increasingly self-defeating. It’s now 2026, and some of the brand’s headline smartwatch features still depend on what phone you’re using. Is your Galaxy Watch paired with a Samsung smartphone?3177 votesYes, I use a Galaxy Watch paired with a Samsung smartphone.89%No, I use a Galaxy Watch, but…

Alzheimer’s disease (AD) is one of the most prevalent and clinically challenging neurodegenerative disorders worldwide [1]. In 2024, it affects nearly 7 million Americans aged 65 and older, and as populations continue to age, U.S. care costs are expected to exceed $1 trillion annually by 2050 [2]. Globally, AD cases are projected to rise to 78 million by 2030 and 153 million by 2050, placing an immense socioeconomic and healthcare burden on societies [3]. Although the precise etiology of AD remains elusive, extensive evidence implicates amyloid-β (Aβ) misfolding, tau hyperphosphorylation, and their abnormal aggregation as key drivers of neuronal injury…

SED News is a monthly podcast from Software Engineering Daily where hosts Gregor Vand and Sean Falconer unpack the biggest stories shaping software engineering, Silicon Valley, and the broader tech industry. In this episode, they cover the resurgence of ARM and CPUs as serious compute infrastructure for running local AI agents, a supply chain attack on LiteLLM that exposed API credentials across thousands of developer environments, and the arrival of OpenCode as a fully open source alternative to Claude Code and Codex. They also discuss the diverging strategies of Anthropic and OpenAI following the Pentagon contract controversy, and what it…

Students who use AI tools extensively may struggle with knowledge retention, according to new research. Brazilian social scientist Andre Barcaui looked at two groups of students, one using ChatGPT as a study aid and the other using more traditional methods, before giving them a surprise test after 45 days. He found that those who had depended on AI scored an average of 57.5 percent on a knowledge retention test, compared to an average of 68.5 percent for those who had studied traditionally. This randomized controlled trial showed that unrestricted use of ChatGPT as a study aid can impair long-term knowledge…
