A palestra “Designing New Interfaces for Musical Expression: Opportunities and Challenges” será apresentada no dia 4 de junho, às 16:00, na sala B018, e será moderada pelo docente do DEI, Gilberto Bernardes de Almeida.

Resumo:

“Computer music has a compelling history, with initial attempts to perform computer-generated music live dating back several decades. Performing sounds generated by computers presents numerous opportunities and challenges for musical expression. Though virtually any sound can be synthesized and performed arbitrarily without the inherent physical constraints of strings, membranes, and columns of air, this freedom poses unprecedented challenges to instrument designers, composers, musicians, and concertgoers.
In this talk, I will discuss the design and use of several new interfaces developed at the Input Devices and Music Interaction Laboratory at McGill University, ranging from self-contained digital musical instruments and prosthetic interfaces for dance performances to fMRI-compatible electronic instruments used in neuroscience studies. I will highlight the unique context and challenges of each development, showcasing the critical importance of interdisciplinary research in this field. Finally, I will present an overview of the Centre for Interdisciplinary Research in Music Media and Technology (www.cirmmt.org), a leading research centre established 25 years ago, focusing on sound and music, based in Montreal, QC, Canada. CIRMMT’s mandate is to eliminate the barriers between disciplines and research domains by supporting researchers and artists from various backgrounds to interact in ways not possible in traditional academic environments.”

A palestra intitulada “Governança de Inteligência Artificial: Erros, Desinformação e Desafios Contemporâneos” será apresentada no dia 16 de maio, às 10:30, na sala I-105.

Resumo:

Nesta sessão dupla, os investigadores André Lemos e Haline Maia exploram, a partir de perspectivas críticas e interdisciplinares, alguns dos principais dilemas que emergem da crescente presença da inteligência artificial na vida social, educacional e informacional.

André Lemos foca a sua apresentação nas falhas e perturbações que atravessam os sistemas algorítmicos, discutindo como a IA pode ser não apenas eficiente, mas também precária, incerta e opaca. Através de uma abordagem sociotécnica, analisa os erros da IA como elementos estruturantes da cultura digital contemporânea.

Haline Maia traz à discussão as implicações da IA nos ecossistemas informativos, com ênfase no jornalismo e na desinformação. Partindo de um estudo que combina metodologias participativas e avaliação ética de impacto tecnológico, apresenta reflexões sobre como alinhar tecnologias como deepfakes e fact-checking automatizado com valores humanos fundamentais.

Cada uma das intervenções terá uma duração de 30 minutos, terminando com um espaço de debate com o público. A palestra integra a pesquisa Governança de Inteligência Artificial no Brasil e em Portugal: Cruzamento e Tendências. Apoio CNPQ/MCTI/FNDCT 22/2024.

A palestra intitulada “Safe Evolution of Smart Contracts Supported by LLMs and SMT Solvers” será apresentada dia 24 de abril, às 14:00, na sala B006, com a moderação de Nuno Macedo (DEI).

Resumo:

“The focus of this talk is a framework that supports the safe deployment and upgrade of smart contracts based on the design-by-contract (dbc) paradigm. The input is (i) an interface specification with invariants and pre- and postconditions for each function, and (ii) an implementation to be verified. The deployed version of a smart contract must conform to this specification. Specification evolution might involve both changing the data representation as well as extending the interface with new functions, provided the evolved specification is a refinement of the original one. A distinguishing feature of the overall approach is the automation of the verification process in a hidden formal methods style. Since developers tend to be reluctant to provide formal specifications for software components, we are investigating state-of-the-art NL processing technologies, using Large Language Models (LLMs), particularly, ChatGPT, to automatically infer formal (dbc) interface specifications from textual requirements. Also, when an upgrade involves change of data representation, we use the Alloy Analyser to automatically infer the relation between the two data representations. The applicability of the framework is evaluated in the context of Solidity smart contracts that implement some Ethereum standards. This project is a collaboration between Universidade Federal de Pernambuco (Brazil), The University College Oxford Blockchain Research Centre (UK), and The Blockhouse Technology Limited (UK).”

A palestra intitulada “Cyber Security Threat Landscape in the Context of Industry 4.0” será apresentada dia 14 de abril, às 14:30 (1h), na sala I-105, com a moderação de Pedro Diniz (DEI).

Resumo:

Industry 4.0 is revolutionizing the ways in which industries function. Big data, industrial control systems, supervisory control, and data acquisition systems, smart machines, robotics, internet of things (IoT) etc., all fall under the umbrella of Industry 4.0. With the fourth industrial revolution comes new operational risks for smart manufacturers, connected devices, and digital supply networks. With increasing digital transformation and interconnected nature of industry 4.0, cyberattacks can have significantly greater effects than ever before while the manufacturers may not be prepared for the potential risks. Without the strong cybersecurity practices in place, industries can be subject to industrial property theft, production sabotage, industrial espionage etc. To address the cyber risks adequately in the era of industry 4.0, it is crucial to make the cyber security strategies secure and resilient and integrate them fully in the organizational strategies from the beginning. This talk will discuss different types of attacks smart industries can be targeted for. The talk will also recommend some techniques and cyber security practices that the manufacturing industries must adopt to protect themselves against such attacks.

A palestra intitulada “Towards AI-Assisted Synthesis of Verified Dafny Methods”, será apresentada no dia 24 de março, às 11:00, na sala I-105, moderada por Rui Maranhão (DEI).

Resumo:

“LLMs show “great promise” in code synthesis. Can they keep the promise and ensure that the synthesized code is provably correct?
In this talk I will present our work on synthesizing formally verified Dafny methods. LLMs don’t know much about Dafny, but they learn fast with proper RAG-CoT prompts. We spent 6 weeks hand-coding 50 verified algorithms in Dafny, and then GPT4 was able to generate 103 new ones with the right postconditions and the necessary verification hints.
Md Rakib Hossain (Misu) co-led the work, with assistance from Iris Ma. Joint work with James Noble.”
