While apprehensions about employment and schools dominate headlines, the truth is that the effects of large-scale language models such as ChatGPT will touch virtually every corner of our lives. These new tools raise society-wide concerns about artificial intelligence’s role in reinforcing social biases, committing fraud and identity theft, generating fake news, spreading misinformation and more. A team of researchers is seeking to empower tech users to mitigate these risks. The authors demonstrate that people can learn to spot the...

A new system represents the first time that the capabilities of conventional beam-scanning lidar systems have been combined with those of a newer 3D approach known as flash lidar. The nonmechanical 3D lidar system is compact enough to fit in the palm of the hand and solves issues of detecting and tracking poorly reflective objects.

FRIDA, a robotic arm with a paintbrush taped to it, uses artificial intelligence to collaborate with humans on works of art. Ask FRIDA to paint a picture, and it gets to work putting brush to canvas. The robot uses AI models similar to those powering tools like OpenAI’s ChatGPT and DALL-E 2, which generate text or an image, respectively, in response to a prompt. FRIDA simulates how it would paint an image with brush strokes and uses machine learning...

Researchers have explained how large language models like GPT-3 are able to learn new tasks without updating their parameters, despite not being trained to perform those tasks. They found that these large language models write smaller linear models inside their hidden layers, which the large models can train to complete a new task using simple learning algorithms.

Interactive cyber-physical human: Generating contact-rich whole-body motions
February 6, 2023
| No Comments
| Artificial Intelligence
Performing human-like motions that involve multiple contacts is challenging for robots. In this regard, a researcher has envisioned an interactive cyber-physical human (iCPH) platform with complementary humanoid (physical twin) and simulation (digital twin) elements. iCPH combines human measurement data, musculoskeletal analysis, and machine learning for data collection and augmentation. As a result, iCPH can understand, predict, and synthesize whole-body contact motions.

SUVs don’t often get called beautiful. Rugged, cool, maybe even stylish on occasion. Marketing departments like to pepper SUV launches with adjectives that tap into our primordial instincts to haul stuff or ram through forest roads, but the typical Range Rover, Toyota RAV4, or Volvo has long since left its utilitarian roots behind. Looks, as opposed to actual ability, are increasingly important with SUVs. Looks are also entirely subjective, but we’ll go ahead and say it: Inside and out,...
