DEI Talks | “The Cognitive and Human Factors of Formal Methods” by Prof. Shriram Krishnamurthi (Brown University)

The talk entitled “The Cognitive and Human Factors of Formal Methods” will be given on 23 July at 11:00 am in room B025, moderated by Prof. Alexandra Mendes (DEI).

About the Talk:

“As formal methods improve in expressiveness and power, they create new opportunities for non-expert adoption. In principle, formal tools are now powerful enough to enable developers to scalably validate realistic systems artifacts without extensive formal training. However, realizing this potential for adoption requires attention to not only the technical but also the human side—which has received extraordinarily little attention from formal-methods research.
This talk presents some of our efforts to address this paucity. We apply ideas from cognitive science, human-factors research, and education theory to improve the usability of formal methods. Along the way, we find misconceptions suffered by users, how technically appealing designs that experts may value may fail to help, and how our tools may even mislead users.”

DEI Talks | “On the State of Client-Side Web Vulnerabilities: DOM-XSS and JavaScript Libraries” by Prof. Limin Jia

The talk entitled “On the State of Client-Side Web Vulnerabilities: DOM-XSS and JavaScript Libraries” will be given on 24 July at 2:30 pm in room B025, moderated by Prof. Alexandra Mendes (DEI).

About the Talk:

“Client-side web vulnerabilities continue to pose significant security risks. In this talk, I will present two research efforts that provide a broader view of the modern web attack surface. First, I will introduce SWIPE, a system for large-scale detection of DOM-based cross-site scripting (DOM-XSS). SWIPE combines interaction-based fuzzing with dynamic symbolic execution (DSE) to systematically explore event-driven behaviors and automatically synthesize URL parameters and fragments. This enables the discovery of vulnerabilities that traditional static or non-interactive techniques miss, significantly improving detection coverage. Second, I will present LIBINSPECTORJS, an end-to-end pipeline for identifying vulnerable JavaScript libraries and assessing their exploitability in practice. Our initial results show that vulnerable libraries are widespread, but not all instances lead to exploitable conditions.”

About the Speaker:

DEI Talks | “Trustworthy AI Under Constraints: From Small Language Models to Adaptive Antibiotic Treatment” by Vi Ngoc-Nha Tran (UiT The Arctic University of Norway)

The talk entitled “Trustworthy AI Under Constraints: From Small Language Models to Adaptive Antibiotic Treatment” will be given on 14 July at 4:00 pm in room B001, moderated by Prof. Gil Gonçalves (DEI).

About the Talk:

“This talk presents two current research directions in trustworthy and efficient AI systems for sensitive domains. The first part focuses on small language models as a practical alternative to large language models in settings where cost, energy use, privacy, local deployment, and governance are important. I will present our recent work on privacy risks in chatbots built on small language models, showing that standard template-based evaluations can underestimate personally identifiable information leakage. Our results motivate a broader view of reliability, where prompts, role formatting, decoding choices, and deployment settings are treated as part of the AI system itself.
The second part introduces OptiRegi, a project that uses reinforcement learning to study optimized dynamic antibiotic dosing regimens. The goal is to explore how treatment decisions can adapt over time while balancing bacterial killing, toxicity, resistance development, and changing infection dynamics. Together, these two projects highlight a common theme: building AI systems that remain trustworthy under real-world constraints, from privacy and deployment challenges in small language models to safe and adaptive treatment optimization.”

DEI Talks | “Natural and artificial trust for decision-making in human-machine teamwork” by Carolina Centeio Jorge

The talk entitled “Natural and artificial trust for decision-making in human-machine teamwork” will be given on 25 June at 11:00, in room B011.

About the Talk:

“Human-machine teams count on both humans and artificial agents to work together collaboratively. In human-human teams, we use trust to make decisions, such as which teammate should do which task, based on what we believe might be successful. Our prediction of task success is based on our beliefs of others’ trustworthiness, which can be divided into several dimensions, e.g., competence, willingness, external factors, etc.

As artificial teammates’ autonomy increases, the variation of interdependences in human-machine teams increases too. As such, team members need to consider the different possibilities to achieve task success as a team, making the best use of human-machine collaboration. It is then important that all members involved, both humans and machines, have the necessary beliefs of trust and trustworthiness to make decisions that ensure the team’s goal and mitigate possible risks. By formalising trust and trustworthiness beliefs, we can increase the transparency of decisions, either made by humans or machines.

In this talk, I will go over notions of trust, trustworthiness, interdependence and coactive design, all in the context of decision-making in human-machine teams. I will present some of our multidisciplinary research which allow us to increase our (and the machine’s) understandability of the human teammate when collaborating with a machine and, consequently, make the machine teammate more understandable to the human.”

DEI Talks | “Hybrid neural systems: neuromorphic computing for real-time control of brain activity” by Paulo Aguiar (i3S-U.Porto)

The talk, entitled “Hybrid neural systems: neuromorphic computing for real-time control of brain activity“, will be given on 15 June at 2:00 pm in room I-105. Henrique Lopes Cardoso (DEI) will chair the session.

Abstract:

The brain is a powerful model for fast, adaptive and energy-efficient information processing. Translating these principles into computing systems is a major challenge with direct relevance for the next generation of intelligent neural interfaces. In this talk I will present work from my research group where we developed a hybrid neural system combining biological neurons with neuromorphic hardware, where artificial spiking neurons process ongoing brain activity in real time. By converting biological signals into spike-based representations, we trained spiking neural networks (SNNs) to identify short-lived electrophysiological patterns and deployed them on neuromorphic hardware. This system was integrated with open-source electrophysiology tools to create a closed-loop pipeline capable of detecting ongoing brain states and triggering targeted stimulation with low latency. Using this approach, we show that hybrid systems linking artificial and biological neurons can support real-time interaction with living neural circuits. These results provide a proof-of-concept for accessible neuromorphic neural interfaces and open new possibilities for adaptive, low-power and biologically inspired computing technologies.

DEI Talks | “nanoML: Pushing the Limits of Edge AI with Weightless Neural Networks” by Prof. Lizy John (UT Austin)

The talk entitled “nanoML: Pushing the Limits of Edge AI with Weightless Neural Networks”, will be given by Prof. Lizy Kurian John (University of Texas at Austin) on 6 May at 2.30 pm in room I-105. The session will be moderated by Prof. Pedro Diniz (DEI).

About the Talk:

“Mainstream artificial neural network models, such as Deep Neural Networks (DNNs) are computation-heavy and energy-hungry. Weightless Neural Networks (WNNs) are natively built with RAM-based neurons and represent an entirely distinct type of neural network computing compared to DNNs. WNNs are extremely low-latency, low-energy, and suitable for efficient, accurate, edge inference. The WNN approach derives an implicit inspiration from the decoding process observed in the dendritic trees of biological neurons, making neurons based on Random Access Memories (RAMs) and/or Lookup Tables (LUTs) ready-to-deploy neuromorphic digital circuits. WNNs are a natural fit for edge AI due to the low area, energy and latency properties offered by them. This talk will describe the state of the art of Weightless Neural Networks, and their applications for edge inferencing.”

DEI Talks | “When AI meets Performance Engineering: Challenges and Opportunities” by Prof. Lizy John (UT Austin)

The talk entitled “When AI meets Performance Engineering: Challenges and Opportunities”, will be given by Prof. Lizy Kurian John (University of Texas at Austin) on 29 April, at 2.30 pm, in room L119 (DEMec). The session will be moderated by Prof. Pedro Diniz (DEI).

About the Talk:

“Artificial Intelligence/Machine Learning (AI/ML) has transformed hardware design, software systems, and system architectures. Emerging hardware for AI accelerators have become heterogeneous and complex, that traditional modeling methodologies, benchmarks, and metrics for prior systems may not work for assessing AI models and AI hardware. The single-most commonly used operation in AI is matrix multiplication. Hardware accelerators like GPUs have created Tensor Cores to support matrix multiplication. Google TPUs support matrix multiplication by the hardware systolic arrays. However, matrix multiplication cannot be a reliable benchmark for benchmarking, due to its high sensitivity to optimizations. The MLPerf consortium creates ML benchmarks, however those benchmarks are prohibitively difficult to manage for many small companies and academic researchers. What are good benchmarks for AI/ML? How can you evaluate AI hardware in pre-silicon and post-silicon stages? Complete system simulation was a popular mode of pre-silicon evaluation but prohibitively expensive. This talk will describe some of the opportunities and challenges when AI meets Performance Engineering.”
