Lemma 3. Consider the ReLU activation The proof of Theorem 1 is given below. The inequality 3 uses strictly monotone property of p () . Code is available at this link. The neural networks are updated using Adam with learning rate initializes at 0.035 and All of them have no communication constraints. The training time is shown in Table 1.

This intervention significantly improves the performance of LLaMA models on the TruthfulQA benchmark.

Recent advances in constrained reinforcement learning (RL) have endowed reinforcement learning with certain safety guarantees.

Plus: social media firms have agreed to be assessed on how effectively they protect teens' mental health A "QuitGPT" campaign is urging people to cancel their ChatGPT subscriptions In September, Alfred Stephen, a freelance software developer in Singapore, purchased a ChatGPT Plus subscription, which costs $20 a month and offers more access to advanced models, to speed up his work. But he grew frustrated with the chatbot's coding abilities and its gushing, meandering replies. Then he came across a post on Reddit about a campaign called QuitGPT. QuitGPT is one of the latest salvos in a growing movement by activists and disaffected users to cancel their subscriptions. In just the past few weeks, users have flooded Reddit with stories about quitting the chatbot. And while it's unclear how many users have joined the boycott, there's no denying QuitGPT is getting attention.

But not in the way Fukushima's geneticists thought. Breakthroughs, discoveries, and DIY tips sent six days a week. In the regions surrounding the Fukushima nuclear plant disaster in northeast Japan, radioactive domestic pigs and wild boar are rapidly interbreeding. While far from the only recent incident of animal hybridization, the situation is presenting wildlife biologists with an unprecedented opportunity to examine the issue in real-time, as well as provide a template for studying the growing problem worldwide. In 2011, a 9.0 magnitude undersea earthquake in the Pacific Ocean rocked Japan.

AI Is Here to Replace Nuclear Treaties. The last major nuclear arms treaty between the US and Russia just expired. Some experts believe a combination of satellite surveillance, AI, and human reviewers can take its place. For half a century, the world's nuclear powers relied on an intricate and complex series of treaties that slowly and steadily reduced the number of nuclear weapons on the planet. Those treaties are gone now, and it doesn't appear that they'll be coming back anytime soon.

Plus: Anthropic's new tools are freaking out the markets Every time OpenAI, Google, or Anthropic drops a new frontier large language model, the AI community holds its breath. It doesn't exhale until METR, an AI research nonprofit whose name stands for "Model Evaluation & Threat Research," updates a now-iconic graph that has played a major role in the AI discourse since it was first released in March of last year. The graph suggests that certain AI capabilities are developing at an exponential rate, and more recent model releases have outperformed that already impressive trend. That was certainly the case for Claude Opus 4.5, the latest version of Anthropic's most powerful model, which was released in late November. In December, METR announced that Opus 4.5 appeared to be capable of independently completing a task that would have taken a human about five hours--a vast improvement over what even the exponential trend would have predicted. But the truth is more complicated than those dramatic responses would suggest.
