Title: Principles of Learning from Multiple Tasks Abstract: Deep networks are increasingly trained on data from multiple tasks with the goal of sharing synergistic information across related tasks. A language model, for example, is trained on 10 trillion tokens on tasks ranging from programming, finance, trivia to translation and a vision model is trained on over a billion… |

Speaker: Christopher A. Baldassano Title: Remembering events using schematic knowledge Abstract: Our everyday experiences consist of familiar sequences of events in familiar contexts, and we use our knowledge of the past to understand and remember the present. Research in my lab combines behavioral, eye-tracking, and neuroimaging methods to investigate how prior knowledge of temporal and spatial structure impacts…

Title: How the human brain thinks about itself Abstract: The human brain has a remarkable ability to monitor and evaluate its own mental states, known as metacognition. Metacognition is crucial to success, enabling us to recognise gaps in our knowledge and collaborate effectively. Problems with metacognition are linked to maladaptive behaviours, such as endorsing false… |

Title: Quantifying individuality in neural circuit representations Abstract: Signatures of neural computation are thought to be reflected in the coordinated activity of large neural populations. Neuroscience is now flush with measurements of these activity patterns in humans, animal subjects, and large-scale artificial network models. In this talk, I will address an extensively studied, yet unresolved, question: How should we quantify the extent to which… |

Title: Reimagining the biology of memory Abstract: Over the last half century, there has been a remarkable convergence on the idea that memories are stored at synapses. I will argue that this is only part of the story. A more complete story compels us to recognize the radical ubiquity of memory in living systems,… |

Bio: Itzel is a Ph.D. student at Rice University working with Prof. Xaq Pitkow. She studies perception and control mechanisms that give biological organisms an advantage over machines. She believes understanding how the brain works using mathematical principles is essential to build the next generation of AI systems which are more robust, more general-purpose, less… |

Title: Uncovering latent low-dimensional structure in network connectivity Abstract: Network connectivity constrains the patterns of neural activity in the brain. These constraints are often observed as low-dimensional manifolds in neural activity space. Continuous Attractor Networks (CANs) are a prime example of this type of network phenomenon. Interestingly, there are examples of CANs where the structure or topology…

Title: The structure of individuality in micro-behavioral features of task performance Abstract: Individuality is an intrinsic and essential aspect of mammalian behavior that emerges even in genetically identical organisms experiencing the same environmental conditions. In the International Brain Laboratory (IBL), mice were trained on a visual decision-making task with the explicit goal of establishing a…

Description: Advances in neurotechnology and behavioral tracking have enabled the collection of large-scale neural and behavioral datasets, offering new opportunities to study brain function in complex settings. However, researchers face significant challenges in integrating and analyzing data across different brain regions, individuals, and behavioral contexts. Inspired by recent successes in large-scale “foundation” models in natural language… |

Title: Multidimensional structure of activity in transcriptomically identified cortical cell types Abstract: The cerebral cortex is comprised of hundreds of distinct cell types, connected into a network that underpins cognition. To characterize the geometry of population activity in these cells, we recorded from thousands of neurons simultaneously in mouse visual cortex, and used post-hoc in… |
