Artificial Intelligence – The importance of contextual knowledge

Luís M.P. Correia – Department of Informatics of Faculdade de Ciências of Universidade de Lisboa

Abstract:

The debate on whether Artificial Intelligence (AI) is capable of producing intelligent machines is at least as old as AI itself. It is evident that AI has obtained striking results in specific areas (games, data mining, etc.). However, each of these systems is limited to solve the specific problem for which it was created. A central aspect in AI limitations is its limited coupling between symbolic knowledge and reasoning on the one hand, and data based knowledge and uncertainty on the other. Currently this is perhaps the focus of most expected significant advances in AI. Notwithstanding, AI has always offered a variety of cases where these two types of knowledge coexist, from search in state space problems to recent machine learning techniques, such as reinforcement learning and natural language models. We will approach some of these examples showing tha this coupling exists even if in a primary stage when compared to natural intelligence.

Music Creation with Deep Learning Techniques: Achievements and challenges

Jean–Pierre Briot – LIP6, Sorbonne Université, Paris, France

Abstract:

A growing application area for the current wave of deep learning (the return of artificial neural networks on steroids) is the generation of creative content, notably the case of music (and also images and text). The motivation is in using machine learning techniques to automatically learn musical styles from arbitrary musical corpora and then to generate musical samples from the estimated distribution, with some degree of control over the generation. In this talk, we will survey some recent achievements in deep-learning-based music generation, using recent and dedicated generative architectures such as VAE, GAN and Transformer, analyze principles, successes as well as challenges, including the limits of automated generation versus providing assistance to human musicians.

Ethics in AI: A Challenging Task

Ricardo Baeza-Yates, Institute for Experiential AI @ Northeastern University

Abstract:
In the first part we cover five current specific challenges through examples: (1) discrimination (e.g., facial recognition, justice, sharing economy, language models); (2) phrenology (e.g., biometric based predictions); (3) unfair digital commerce (e.g., exposure and popularity bias); (4) stupid models (e.g., Signal, minimal adversarial AI) and (5) indiscriminated use of computing resources (e.g., large language models). These examples do have a personal bias but set the context for the second part where we address four generic challenges: (1) too many principles (e.g., principles vs. techniques), (2) cultural differences (e.g., Christian vs. Muslim); (3) regulation (e.g., privacy, antitrust) and (4) our cognitive biases. We finish discussing what we can do to address these challenges in the near future.

Abstract:

There is strong scientific evidence about the effects of climate change on the global ocean. These changes will have a drastic impact on almost all forms of life in the ocean with further consequences on food security, ecosystem services in coastal and inland communities. Despite these impacts, scientific data and infrastructures are still lacking to better understand and quantify the consequence of these perturbations on the marine ecosystem.

The OcéanIA project has the goal of developing new AI and mathematical modelling tools to contribute to the understanding of the structure, functioning, and underlying mechanisms and dynamics of the global ocean symbiome. These actions are essential to gain a better understanding of the oceans and their role in regulating and sustaining the biosphere. This is also an opportunity to dive into the connections of AI and biodiversity, which can be a major achievement for the sustainability of human societies on the blue part of the planet.
