Artificial intelligence (AI) is one of the most fascinating and impactful fields of science and technology. Every week, we witness new breakthroughs and innovations that demonstrate the power and potential of AI. In this blog post, we will share with you some of the most interesting news items about AI from Week 21. You will learn about how AI is enabling new forms of creativity, restoring mobility to people with disabilities, shaping the future of regulation, enhancing remote communication and creating agile robots. We hope you enjoy reading this blog post and discovering more about the amazing world of AI.
Nvidia, the US chipmaker, has created the H100 processor that is powering the generative AI boom. The H100 is a specialized chip that can perform complex mathematical operations at high speed and low power consumption. The chip is in high demand for applications such as ChatGPT, a conversational AI system that can generate realistic text and speech; deepfakes, synthetic media that can manipulate faces and voices; and NFTs, digital tokens that can represent unique artworks and collectibles. These applications rely on generative adversarial networks (GANs), a type of AI algorithm that can create new data from existing data. The H100 chip can accelerate the training and inference of GANs, making them faster and more efficient. As a result, Nvidia’s market value has skyrocketed towards $1tn, surpassing its rivals Intel and AMD in the semiconductor sector. However, Nvidia faces competition from other chipmakers such as Graphcore and Cerebras, who are also developing specialized chips for AI. Nvidia’s CEO Jensen Huang said that the company is constantly innovating and investing in new technologies to stay ahead of the curve. He also said that generative AI is a new form of creativity that can benefit humanity in many ways. Source
A paraplegic patient has been able to walk again thanks to a novel AI-based device that connects his brain and his legs. The device, called a ‘digital bridge’, decodes the brain signals that indicate the intention to move and sends them to a robotic exoskeleton that supports the lower limbs. The device also provides sensory feedback to the brain, creating a closed-loop system that restores natural gait and balance. The device was tested on a 30-year-old man who was paralyzed from the waist down due to a spinal cord injury. He was able to walk for more than 300 meters with the device, as well as climb stairs and sit down. The device was developed by a team of researchers from France, Switzerland and Italy, who published their results in the journal Nature. They said that the device is a breakthrough in neurotechnology that could improve the quality of life and autonomy of people with spinal cord injuries. They also said that the device could be adapted to other types of paralysis, such as stroke or cerebral palsy. Source
OpenAI, the maker of ChatGPT, has warned over a potential split with Europe as the bloc advances its regulation on AI. The EU has proposed a legislation that aims to ban or restrict high-risk AI applications, such as facial recognition, social scoring and biometric surveillance. The legislation also imposes fines and obligations on providers and users of AI systems that could harm human rights, safety or privacy. OpenAI’s chief Sam Altman said that he has “many concerns” over the regulation, which he thinks could stifle innovation and create a rift with the US and China. He said that the regulation could limit the development and deployment of beneficial AI applications, such as healthcare, education and climate change. He also said that the regulation could create a “splinternet” of AI, where different regions have different rules and standards for AI. He urged the EU to collaborate with other countries and stakeholders to find a global solution for AI governance. Source
Researchers have developed a robot that can bring remote users to life in real time. The robot, called ReMotion, occupies physical space on behalf of the user and automatically mirrors the user’s movements in real time. The robot also conveys key body language cues, such as head orientation, eye gaze and hand gestures. The robot could be used for telepresence, social interaction and entertainment. The robot was developed by a team of researchers from Stanford University and the University of California, Berkeley. They used a combination of motion capture, computer vision and robotics to create ReMotion. They tested the robot with 20 pairs of participants who engaged in various tasks, such as storytelling, trivia and charades. They found that the robot improved the sense of presence, engagement and enjoyment of the remote users. They also found that the robot was able to express emotions and intentions through its movements. The researchers said that ReMotion is a novel way to enhance remote communication and collaboration. They also said that ReMotion could be extended to support multiple users and different types of robots. Source
Engineers have designed a robot that can move like a centipede with 12 legs. The robot can traverse uneven terrain, climb obstacles and squeeze through narrow gaps. The robot could be used for exploration, rescue and inspection tasks. The robot was designed by a team of engineers from the University of California, Santa Barbara. They were inspired by the locomotion and morphology of centipedes, which are agile and adaptable animals. They used a modular design approach, where each leg is composed of two identical segments that can be connected in different ways. They also used a distributed control system, where each leg has its own controller that communicates with its neighbors. They tested the robot on various scenarios, such as walking on sand, grass and rocks; climbing over a pipe and a ramp; and passing through a narrow gap. They found that the robot was able to adapt its gait and posture to different situations. They also found that the robot was robust to damage and failure of some legs. The engineers said that the robot is a proof-of-concept of a new class of many-legged robots. They also said that the robot could be scaled up or down, and equipped with different sensors and actuators for different applications. Source
