Talk on Thursday Jun 08, 2023 at 11:00 Place: IFISC Seminar Room Title: Understanding the structure and functioning of oceans’ microbiomes: toward a holistic view Speaker: Daniele Iudicone , Stazione Zoologica Anton Dohrn Abstract: Plankton is the main actor in the largest terrestrial biome and the modulator of processes related to key ecosystem services, such as climate and food supply through the carbon cycle. Current gaps in the knowledge of its biology and ecology are a serious limitation to the assessment of its status and dynamics; the latter are a major source of uncertainty in current predictive models of ocean ecosystem services in the presence of anthropogenic stressors. Many of the current limitations come from a terrestrial bias in theoretical frameworks. Indeed, pelagic plankton communities are in highly dynamic equilibrium under physical and chemical constraints and feedbacks, an equilibrium that also takes into account the stochasticity inherent in many processes (from gene expression to nutrient availability and encounter rates). To understand their structure and functioning, therefore, we must adopt multidisciplinary approaches that allow us to make simultaneous sense of three complex coupled systems, consisting of the turbulent fluids that make up the atmosphere and oceans, the internal biology of organisms and the network of their interactions. We thus propose to combine remote sensing with extensive in situ observations, state-of-the-art meta-omics approaches with systems biology, and theoretical ecology with artificial intelligence to advance theories, models and ecological paradigms to promote the seascape as a new conceptual framework.

IFISC Seminar on Thursday Jun 01, 2023 at 15:00 Place: IFISC Seminar Room Title: Implementing engrams from a machine learning perspective: matching for prediction Speaker: Jesús Marco, Instiituto de Física de Cantabria Abstract: We will discuss how we might design a computer system to implement memory representations (engrams) using neural networks, with the main aim of exploring new ideas using machine learning techniques, guided by challenges in neuroscience.&nbsp; We will analyze the use of latent neural spaces as indexes for storing and retrieving information in a compressed format based in autoencoders, an unsupervised method supporting predictive learning. We then consider how different states in latent neural spaces corresponding to different types of sensory input could be linked by synchronous activation, providing the basis for a sparse implementation of memory using concept neurons. Finally, we will comment on some of the challenges and questions that link neuroscience and data science and that could have implications for both fields.
