Computer science professors James Pustejovsky and Nikhil Krishnaswamy of Colorado State University have spent the past few years developing the Diana prototype in their multimultimodal simulation work, which exists today as an interactive avatar on a computer, iPad or iPhone. Diana is a teaching assistant designed to respond to students’ nonverbal and visual cues in an effort to help middle-school teachers run their classrooms more smoothly. As students interact in the classroom, the goal is for Diana to notice students’ facial expressions, conversations, gazes and gestures to infer whether they could use help or are getting distracted. Diana then responds by engaging them in conversation or prompting the teacher. The tool could be especially useful when a teacher divides students into small groups and can only focus on one at a time, Dr. Pustejovksy says. Next, the researchers want to teach Diana to reliably recognize faces and voices, particularly diverse skin colors, accents and local dialects—a common oversight in data collection that can lead to gaps in AI’s effectiveness. They plan to strengthen Diana’s capabilities by collecting more visual and audio recognition data from student interactions in five middle schools in Colorado this fall.  Read the full article in the WSJ on Brandeis Now (subscription needed) as well as the Fox5 New York television coverage.

Professor James Pustejovsky was awared a $400,000 NSF Grant for his project entitled, "Elements: Towards a Robust Cyberinfrastructure for NLP-based Search and Discoverability over Scientific Literature". This project creates an open platform for accessing and mining information from scientific texts that provides access to an array of software, computing resources, and publication data. Current search technologies typically find many relevant documents, but do not extract and organize the information content of these documents or suggest new scientific hypotheses based on this organized content. Natural Language Processing (NLP) strategies are a recognized means to approach this problem, and this project develops the cyberinfrastructure to support sophisticated search and retrieval from scientific publications, use and augmentation of facilities for advanced and well-established natural language processing and machine learning tools, and extraction and aggregation of data from scientific publications. See further information on the NSF Grant:
A paper recently published in Cell Press, Patterns, a prestigious journal in the field of data science in interdisciplinary research, was the work of two Brandeis faculty members and two Brandeis undergraduates. The paper entitled, "Network-based Virus-host Interaction Prediction with Application to SARS-CoV-2," was co-authored by undergradates, Feng Chen and Hangyu Du, and Computer Science Professors Hongfu Liu and Pengyu Hong, as corresponding authors. The machine learning-based model proposed by the authors in the paper provides the science community with crucial and novel insights to combat SARS-CoV-2. A link to the publication can be found here:

Researchers at the Materials Research Science and Engineering Center (MRSEC) are harnessing the power of swirling cellular proteins to create self-propelling fluids and have taken significant steps toward understanding the swirl and controlling its flow.  In a November paper in the journal Soft Matter ("Machine Learning Forecasting of Active Nematics"), professor of computer science Pengyu Hong, Fraden and Hagan demonstrated how computers could learn purely from experimental data to predict the emergence and behavior of swirl defects using deep learning techniques.

One day, self-propelling liquids could be used to create a class of liquid drugs that are injected into the bloodstream and then autonomously flow toward a specific group of cells or organs. Because the swirl is made from components already in our cells, it wouldn’t be rejected by our bodies.This is another important step towards understanding the swirl’s overall motion.

With support from the Robust Intelligence program in the Division of Intelligent and Information Systems (IIS) and the NSF 2026 Fund Program in the Office of Integrated Activities, investigators at Boston College and Professor James Pustejovsky's team at Brandeis University are addressing the challenge of creating Artificial General Intelligence by synthesizing symbolic or logical reasoning, learning through interaction with the environment, as well as state-of-the-art neural networks. Inspired by the structure of natural (e.g., human) intelligence, the resulting mental architecture deploys each of these strategies for the problems they excel at (the "Best of All Worlds?, or BAW, approach). Successful completion of this project will facilitate a range of research projects in AI and psychology/neuroscience. Long-term, the development of AGI is expected to have significant benefits to society, by enabling computers to develop abstract concepts grounded in experience with the world, and to generate novel ideas and inventions. This project will also help broaden student training and participation of women and underrepresented minorities. Read Professor Pustejvosky's interview with BrandeisNow!

This project aims to prototype a new architecture and test it against an open-ended task that is difficult for artificial intelligence but mastered by human toddlers everywhere: uncovering the affordances of blocks, containers, and other small objects. The primary aims are to build a virtual world that a simulated infant can explore, manipulate, and learn from; build a working prototype of a simulated infant incorporating key aspects of the BAW mental architecture; and evaluate the performance of the agent on several difficult, open-ended tasks. This architecture facilitates incorporation of key concepts from the study of natural intelligence that are infrequently used in artificial intelligence: mental models, exploratory play, and chunking.

Cracking the Genetic Code: Two Brandeis computer scientists are using machine learning and artificial intelligence to analyze the genomes of COVID-19, other relevant corona- and avian-influenza viruses and Ebola. Professor of computer science Pengyu Hong and assistant professor of computer science Hongfu Liu want to identify the small and crucial bit of COVID-19's genetic code that may give rise to two of its most lethal and unique attributes. The advanced machine learning and artificial intelligence techniques the scientists are using can help sift through massive amounts of data to learn which nucleotide patterns are shared and which might be specific to COVID-19. According to Hong and Liu, artificial intelligence may also be able to predict emerging variations in the genomes of future viruses. Read the full article on BrandeisNow.
