Social media researchers are creating a machine learning program that can detect unwanted sexual advances on Instagram. The program was trained on data from over 5 million direct messages, annotated by a group of young users who experienced conversations that felt unsafe or uncomfortable. The data is helping to increase protection for young users by identifying and cutting off risky interactions sooner.

MIT researchers have developed a new AI technique to figure out what's inside a material simply by observing its surface. The technique can analyze surfaces of uniform, composite and even complex materials, and apply for biological tissues as well. It can identify any damages, cracks, stresses and details of internal microstructures, in a completely noninvasive way.

A team of four research universities have proposed a way to use machine learning technology to flag risky conversations on Instagram without having to eavesdrop on them. This new system is 1,000 times more effective at detecting conversations that contained cyberbullying and other risk factors than existing software, as it takes context and intent into consideration.

David Smith, a retired print technician from Yorkshire, England, and a team of mathematicians, programmers and tiling enthusiasts, have solved a nearly 60-year-old mathematical problem by discovering a single shape that tiles the infinite plane without repeating and overlapping. This discovery, known as the aperiodic monotile, has delighted mathematicians since its discovery by Robert Berger in the mid-1960s.

Stanford University researchers have developed an AI-enabled model called Editable Dance GEneration (EDGE) that can choreograph human dance animation to match any piece of music and be edited by the user. It will be formally introduced at the Computer Vision and Pattern Recognition conference in June, where anyone can pick the tune and watch as EDGE creates a new dance sequence on the 'EDGE Playground' website.

Researchers from ETH Zurich have developed a new programming language called LMQL that increases user control and interaction with large language models like ChatGPT. This programming language combines natural and programming language to guide the language models in a more precise way. LMQL enables a novel way of programming and provides safety constraints to prevent unexpected or controversial outputs.

VCU's Security and Forensics Engineering Lab, under the direction of Irfan Ahmed, focuses on protecting and investigating industrial control systems from malicious cyberattacks. Ahmed's team creates tools and simulations to investigate, detect, and secure an ever-evolving type of cybercrime. Their newly invented solutions are applied in the industrial sector and to assist law enforcement in preventing and responding to both digital and non-digital crimes.

A research team from East China Normal University, led by Li Zhang, has proposed a new method, Max-Difference Maximization Criterion (MDMC), for estimating the importance of terms in text categorization. The method introduces a new weight based off of class information occupancy, which is then combined with Accuracy2 to yield better discrimination of terms. MDMC has been proven to outperform other methods such as ISCA, PCA, and NMF.

Analyzing feces has become a useful tool towards understanding nutrition and health. Fecal samples can indicate whether people have eaten individial foods, and studies to improve nutrition research that try to figure out how certain foods affect our health usually rely on volunteers to keep food diary which is inaccurate and incomplete. This study showed that microbes found in feces can indicate food consumption with 80-87% accuracy.

Ravi Yekkanti is an employee of WebPurify, a content moderation services provider to internet companies such as Microsoft and Play Lab. His job is to make sure everyone in the metaverse is safe and having a good time, as reports of sexual assaults, bullying, and child grooming in the metaverse arise. His job is complex, murky and in-demand, as the burden of safety in the metaverse is left to private security agents such as Yekkanti to intervene.

A new study from MIT and Columbia University has found that providing AI chatbot users with questions as opposed to ready-made answers can help improve their critical thinking skills. This could be beneficial in ensuring that AI-generated information is accurate and not overdependent. These new methods also offer users insight into an AI system’s decision-making process.

The heyday of generative AI has been ushering in a debate over what constitutes art, with AI-generated images and text winning awards and prizes. This raises serious questions about privacy, creativity, and the validity of AI-generated content as an art form. As technology advances, chances of AI-generated content becoming an impediment to creativity or a tool unwittingly used for nefarious purposes continue to increase.

Researchers at University of Florence, University of Modena and Reggio Emilia and University of Pisa recently introduced a new computer vision framework that could help fashion designers to visualize their designs, using AI models in fashion design. This new framework could help fashion designers find new inspiration and identify potential issues. The models used in this area were based on latent diffusion models, which could produce higher quality images, rather than generative adversarial networks (GANs). The researchers also created new datasets for training the model and showed good performance in initial evaluations.

The demand for electric vehicles has been booming over the past decade, with more than 10 million sold in 2022 and a 35 percent growth predicted for this year. EV market share more than tripled from 2020 to 2022, with China leading the global charge due to small, cheap models of EVs. Europe is the second-largest EV market, followed by the US with a 55 percent growth. Reducing reliance on combustion engine vehicles is an important part of the transition to renewable energy, though EVs also come with their own set of challenges and drawbacks.
