Artificial intelligence may well save us time by finding information faster, but it is not always a reliable researcher. It frequently makes unsupported claims that are not backed up by reliable sources. A study by Pranav Narayanan Venkit at Salesforce AI Research and colleagues found that about one-third of the statements made by AI tools like Perplexity, You.com and Microsoft’s Bing Chat were not supported by the sources they provided. For OpenAI’s GPT 4.5, the figure was 47%.Artificial intelligence may well save us time by finding information faster, but it is not always a reliable researcher.

What happens when we get out of the driver’s seat and our vehicles become autonomous? Mathematician Viktor Larsson is developing methods to enable cars and drones to see their surroundings. This is his insight into the self-driving present and future.What happens when we get out of the driver’s seat and our vehicles become autonomous?

When researchers are building large language models (LLMs), they aim to maximize performance under a particular computational and financial budget. Since training a model can amount to millions of dollars, developers need to be judicious with cost-impacting decisions about, for instance, the model architecture, optimizers, and training datasets before committing to a model.When researchers are building large language models (LLMs), they aim to maximize performance under a particular computational and financial budget.

Training humanoid robots to hike could accelerate development of embodied AI for tasks like autonomous search and rescue, ecological monitoring in unexplored places and more, say University of Michigan researchers who developed an AI model that equips humanoids to hit the trails.Training humanoid robots to hike could accelerate development of embodied AI for tasks like autonomous search and rescue, ecological monitoring in unexplored places and more, say University of Michigan researchers who developed an AI model that equips humanoids to hit the trails.Robotics[#item_full_content]

To train artificial intelligence (AI) models, researchers need good data and lots of it. However, most real-world data has already been used, leading scientists to generate synthetic data. While the generated data helps solve the issue of quantity, it may not always have good quality, and assessing its quality has been overlooked.To train artificial intelligence (AI) models, researchers need good data and lots of it.
