Designing a great video game is a balancing act, especially in strategy games where the thrill often comes from tackling the unexpected. Whether it’s an enemy ambush or a rare loot drop, the element of surprise keeps players on their toes. But too much randomness can feel unfair, while too little can make a game predictable and boring. Enter the world of probability-driven game design, a method that introduces structured uncertainty into gameplay. A new framework introduced by Katz Schoo researchers uses mathematical tools to strike this balance, creating levels that are not only engaging but varied and challenging.

Researchers have developed a method using a powerful technology to remove unwanted noise from the audio recordings of bird sounds. 

The method, called ViTVS, uses an image processing technology to divide audio signals into distinct parts, or segments, for isolating clean bird sounds from a noisy background. The approach, explained in the paper, “Vision Transformer Segmentation for Visual Bird Sound Denoising,” has been accepted for presentation at a conference on the science and technology of spoken language processing—InterSpeech 2024—by researchers from the Katz School’s Department of Computer Science and Engineering and Cornell University’s School of Public Policy.

Two Katz School AI students took first prize at the 2023 UC Berkeley AI Summit Generative AI Hackathon for solving a complex business problem using the latest in generative AI in under two hours. Niranjan Kumar Kishore and Tharun Prabhakar won in the category of “College Student, Data Scientists or Comp Sci,” with Prabhakar completing his generative AI application just two minutes behind Kishore in the contest. Both were awarded $1,000. 

Their winning submissions were an end-to-end automated generative AI application implemented in a secure Google Cloud that used large language models to answer a set of questions on the impact, opportunity and challenges of generative AI, what every CEO should know about generative AI, and generative AI in healthcare.

Katz School mathematics researchers have developed a model that anticipates market crashes and financial bubbles in the Bitcoin industry. 

In the paper, “Why Topological Data Analysis Detects Financial Bubbles?,” Dr. Marian Gidea, associate dean for STEM education and research, and Samuel Akingbade, a Ph.D. student in mathematics, discuss how Topological Data Analysis (TDA), which identifies patterns and features in data not apparent through traditional statistical methods, can be used to detect early-warning signals of financial bubbles.

With the help of AI, scientists can better model climate patterns, identify trends and make predictions, leading to a clearer understanding of climate change and its environmental impact. Katz School students in Artificial Intelligence and Data Analytics did their part for S&P Global Market Intelligence by sifting through large amounts of data, like satellite images that researchers use to monitor climate change, to create a set of geography-specific, super-resolution climate forecasts that will be valuable for climate research, policy planning and risk assessment.
