Published Project aims to expand language technologies
(via sciencedaily.com) Only a fraction of the 7,000 to 8,000 languages spoken around the world benefit from modern language technologies like voice-to-text transcription, automatic captioning, instantaneous translation and voice recognition. Researchers want to expand the number of languages with automatic speech recognition tools available to them from around 200 to potentially 2,000.
Published Tracking radiation treatment in real time promises safer, more effective cancer therapy
(via sciencedaily.com) Radiation, used to treat half of all cancer patients, can be measured during treatment for the first time with precise 3D imaging. By capturing and amplifying tiny sound waves created when X-rays heat tissues in the body, medical professionals can map the radiation dose within the body, giving them new data to guide treatments in real time. It's a first-of-its-kind view of an interaction doctors have previously been unable to 'see.'
Published Team writes letters with ultrasonic beam, develops deep learning based real-time ultrasonic hologram generation technology
(via sciencedaily.com) A team has developed a 'deep learning-based ultrasound hologram generation framework' technology that can freely configure the form of focused ultrasound in real time based on holograms. It is expected to be used as a basic technology in the field of brain stimulation and treatment that requires precision in the future.
Published A type of simple, DIY air filter can be an effective way to filter out indoor air pollutants
(via sciencedaily.com) A study found that inexpensive, easy-to-assemble Corsi-Rosenthal boxes can help reduce exposure to indoor air pollutants. The air filters have already been shown to reduce particles carrying the SARS-CoV-2 virus.
Published Can the AI driving ChatGPT help to detect early signs of Alzheimer's disease?
(via sciencedaily.com) The artificial intelligence algorithms behind the chatbot program ChatGPT -- which has drawn attention for its ability to generate humanlike written responses to some of the most creative queries -- might one day be able to help doctors detect Alzheimer's Disease in its early stages. Research recently demonstrated that OpenAI's GPT-3 program can identify clues from spontaneous speech that are 80% accurate in predicting the early stages of dementia.
Published Words prove their worth as teaching tools for robots
(via sciencedaily.com) What is the best way to teach a robot? Sometimes it may simply be to speak to it clearly. Researchers found that human-language descriptions of tools can accelerate the learning of a simulated robotic arm lifting and using a variety of tools.
Published Cheerful chatbots don't necessarily improve customer service
(via sciencedaily.com) Humans displaying positive emotions in customer service interactions have long been known to improve customer experience, but researchers wanted to see if this also applied to AI. They conducted experimental studies to determine if positive emotional displays improved customer service and found that emotive AI is only appreciated if the customer expects it, and it may not be the best avenue for companies to invest in.
Published Brain flexibility may hasten hearing improvements from cochlear implants
(via sciencedaily.com) Kickstarting the brain's natural ability to adjust to new circumstances, or neuroplasticity, improves how effectively a cochlear implant can restore hearing loss, a new study in deaf rats shows. The investigation, researchers say, may help explain the extreme variation in hearing improvements experienced by implant recipients.
Published Should we tax robots?
(via sciencedaily.com) A small tax on robots, as well as on trade generally, will help reduce income inequality in the U.S., according to economists.
Published New winged robot can land like a bird
(via sciencedaily.com) Researchers have developed a method that allows a flapping-wing robot to land autonomously on a horizontal perch using a claw-like mechanism. The innovation could significantly expand the scope of robot-assisted tasks.
Published New robot does 'the worm' when temperature changes
(via sciencedaily.com) A new gelatinous robot that crawls, powered by nothing more than temperature change and clever design, brings 'a kind of intelligence' to the field of soft robotics.
Published Model shows how intelligent-like behavior can emerge from non-living agents
(via sciencedaily.com) A new model describes how biological or technical systems form complex structures equipped with signal-processing capabilities that allow the systems to respond to stimulus and perform functional tasks without external guidance.
Published Bolstering the safety of self-driving cars with a deep learning-based object detection system
(via sciencedaily.com) Self-driving cars need to implement efficient, effective, and accurate detection systems to provide a safe and reliable experience to its users. To this end, an international research team has now developed an end-to-end neural network that, in conjunction with the Internet-of-Things technology, detects object with high accuracy (> 96%) in both 2D and 3D. The new method outperforms the current state-of-the-art methods and the way to new 2D and 3D detection systems for autonomous vehicles.
Published Computer vision technology effective at determining proper mask wearing in a hospital setting, pilot study finds
(via sciencedaily.com) In a survey and study of hospital employee volunteers, researchers found that a low-cost computer vision system was feasible and well received.
Published Soft robot detects damage, heals itself
(via sciencedaily.com) Engineers have created a soft robot capable of detecting when and where it was damaged -- and then healing itself on the spot.
Published An exotic interplay of electrons
(via sciencedaily.com) Water that simply will not freeze, no matter how cold it gets -- a research group has discovered a quantum state that could be described in this way. Experts have managed to cool a special material to near absolute zero temperature. They found that a central property of atoms -- their alignment -- did not 'freeze', as usual, but remained in a 'liquid' state. The new quantum material could serve as a model system to develop novel, highly sensitive quantum sensors.
Published Pulses driven by artificial intelligence tame quantum systems
(via sciencedaily.com) Original source Machine learning drives self-discovery of pulses that stabilize quantum systems in the face of environmental noise.
Published Making 'transport' robots smarter
(via sciencedaily.com) Imagine a team of humans and robots working together to process online orders -- real-life workers strategically positioned among their automated coworkers who are moving intelligently back and forth in a warehouse space, picking items for shipping to the customer. This could become a reality sooner than later, thanks to researchers who are working to speed up the online delivery process by developing a software model designed to make 'transport' robots smarter.
Published A simpler path to better computer vision
(via sciencedaily.com) Research finds using a large collection of simple, un-curated synthetic image generation programs to pretrain a computer vision model for image classification yields greater accuracy than employing other pretraining methods that are more costly and time consuming, and less scalable.
Published A far-sighted approach to machine learning
(via sciencedaily.com) A new technique enables artificial intelligence agents to think much farther into the future when considering how their behaviors can influence the behaviors of other AI agents, toward the completion of a task. This approach improves long-term performance of cooperative or competitive AI agents.
