  • “Information and randomization in exploration and exploitation,” featuring:

    Robert Wilson, Ph.D.

    Assistant Professor

    University of Arizona

    Abstract: The explore-exploit dilemma is a fundamental behavioral dilemma faced
    by any organism that can learn. Should we explore new options in the
    hopes of learning something new or exploit options we already know to
    be good. In this talk I will present evidence that people use two
    distinct strategies for solving the explore-exploit dilemma: directed
    exploration, in which information seeking drives exploration by
    choice, and random exploration, in which behavioral variability drives
    exploration by chance. In addition I will present initial evidence
    showing that these two types of exploration rely on dissociable neural
    systems.

    Abstract: The remarkable success of neural network models in machine learning has relied on the use of distributed representations — activity patterns that overlap across related inputs. Under what conditions does the brain also rely on distributed representations for learning? There are benefits and costs to this form of representation: it allows rapid, efficient learning and generalization, but is highly susceptible to interference. We recently developed a neural network model of the hippocampus that proposes that one subregion (CA1) may employ this form of representation, complementing known pattern-separated representations in other subregions. This provides an exciting domain to test ideas about learning with distributed representations, as the hippocampus learns much more quickly than the neocortical areas that have often been proposed to contain these representations. I will present modeling and empirical work that provide support for the idea that parts of the hippocampus do indeed learn using distributed representations. I will also present ideas about how hippocampal and neocortical areas may interact during sleep to further transform these representations over time.

  • Nowadays the technology to create videogames and impressive photorealistic scenes is for everyone to reach. Frameworks such as Unity 3D Engine are easy to understand and work with or without any coding experience. So Why not using it to visualize data? You will learn basics on game objects components, UI design and concepts of volume rendering. Just bring your laptop with Unity Engine installed.

    This workshop will provide a high-level overview of the main areas in machine learning with emphasis on supervised and unsupervised ML. We will review the strengths and limitations of ML, describe the bias-variance tradeoff which is one of the most important concepts in ML. Finally, we will review the main steps in a typical ML workflow and the most common problems to avoid.

    GitHub Actions is a relatively new service by GitHub that allows you to run tests, deploy code, and more all from within your repo. This workshop will cover some of the basic use cases of GitHub Actions as well as show some of the more creative ways it can be used to automate your workflows. Attendees should be familiar with Git and GitHub.

    DSCoV Workshop: Intro to PyTorch

    164 Angell Street

    Intro to PyTorch, by Minju Jung

     

    Nowadays, PyTorch is one of the most popular deep learning libraries. In this tutorial, I will cover the basic operations of PyTorch and building a neural network model for image classification. The basic knowledge of deep learning and coding experience with python are required.

  • Data Science Computation and Visualization Workshop

     

    EXPLORATORY DATA ANALYSIS WITH PANDAS IN PYTHON, PART TWO with Andras Zsom

    Exploratory data analysis (EDA) is the first step of any data science project. In the second part of this pandas tutorial, I’ll walk through various visualization types you can use to better understand the properties of your data at a glance using pandas. Coding experience with python is required but no experience with the pandas package is necessary to follow the tutorial.

    EXPLORATORY DATA ANALYSIS WITH PANDAS IN PYTHON, PART ONE with Andras Zsom

     Exploratory data analysis (EDA) is the first step of any data science project. In the first part of this pandas tutorial, I’ll walk through how to read in csv, excel, and sql data into a pandas data frame, how to select specific rows and columns based on index or condition, and how to merge and append various data frames. Coding experience with python is required but no experience with the pandas package is necessary to follow the tutorial.
