  • [ONLINE] Causal Inference in the language of machine learning with Robert Ness

    For July, we are featuring a joint meetup run by Statistical Seminars DC. Register here or at their event. https://www.meetup.com/Statistical-Seminars-DC/events/271973731/ Blurb: Causal inference is having a moment in the machine learning community. The next generation of AI will require algorithms that enable agents to reason causally about the world. But what is causal inference and how does it connect to machine learning? How are the big tech companies and data science organizations applying causal inference? How can we build causal models with deep learning tools like PyTorch? This talk introduces causal inference in the language of machine learning, and illustrates how to build causal models and perform causal reasoning using deep probabilistic models. Code examples are included. Bio: Robert didn't start in machine learning. He started his career by becoming fluent in Mandarin Chinese and moving to Tibet to do developmental economics fieldwork. He later obtained a graduate degree from Johns Hopkins School of Advanced International Studies. After switching to the tech industry, Robert's interests shifted to modeling data. He attained his Ph.D. in mathematical statistics from Purdue University, and then he worked as a research engineer in various AI startups. He has published in journals and venues across these spaces, including RECOMB and NeurIPS, on topics including causal inference, probabilistic modeling, sequential decision processes, and dynamic models of complex systems. In addition to startup work, he is a machine learning professor at Northeastern University.

  • [REMOTE] Shiny Deep Dive

    Online event

    This month, we are co-hosting with Statistical Programming DC. Sign up here or there. Description and Zoom link below. Join the next SPDC online meetup with two members of the Shiny team at RStudio. Barret Schloerke and Carson Sievert work full time on improving the experience of creating visualizations in R and building Shiny apps. Join them for two talks on new packages that can improve your experience building Shiny apps and data visualizations. Schedule: 7 - 7:20pm Reactlog 2.0: Debugging the State of Shiny (Barret) The revamped reactlog provides an updated visual display to traverse through the reactive behavior within your shiny application. Using live shiny applications, we will use reactlog’s directed dependency graph to find missing reactive dependencies in “working” applications and address suboptimal reactive coding patterns. Correcting these coding patterns will reduce the amount of calculations done by shiny and keep reactive objects from being created unnecessarily. 7:20-7:30 Q+A 7:30-7:50 Plot theming made easieR (Carson) The new thematic package provides a simplified and uniform approach to theming ggplot2, lattice, and base R graphics based on a few colors and font(s). This package provides the foundation for shiny’s new plot auto-theming feature, which automatically styles plots based on the application’s styling. 7:50-8 Q+A Zoom Link: https://zoom.us/j/92586102485?pwd=MFlvTThJMzNLWkgrR2xLcHo1dmVPUT09 Zoom Password: spdc-shiny

  • Data Science 2x: Temporal Graphs Models & Machine Translation Quality Estimates

    We've got two data science talks for you! Come out for pizza at 6:30 and we'll get the program started at 7. All are welcome! ------------------------ Talk 1: A system for machine translation quality estimation: a BERT-based model, novel data-set, and user interface. Machine translation is pretty accurate, so it’s critical to find the increasingly few instances of mistranslation. Quality estimation is an automatic method for estimating the quality of machine translation output at run-time, without relying on reference translations. In this presentation, we will introduce a new data-set for quality estimation, which has recently been released for the upcoming World Machine Translation Quality Estimation shared task at ACL in July. We will also share a BERT-based model for predicting translation quality, and a novel user interface for displaying results. Nina Lopatina is a research data scientist at IQT Labs, currently working on machine translation quality estimation. Prior to this project, Nina researched machine learning privacy attacks on speaker identification models. Before joining IQT Labs, Nina researched neural processes and computations underlying decision-making at Berkeley & the National Institute on Drug Abuse. --------------------------- Talk 2: Towards Modeling Temporal Graphs and Embeddings Many real-world graph applications operate on temporal streaming data. Most of the current graph analytics platforms do not natively support such temporal datasets. In this talk we present a way to model temporal graphs and we apply a sliding-window techniques to build temporal node embeddings. Such embeddings can explicitly characterize how nodes and communities change over time. We will use an adaptive authentication use-case to introduce these concepts. Srdjan Marinovic is co-founder and CTO of SignalFrame, a DC-based graph-analytics startup. He leads the development of the company’s temporal graph platform and streaming services. Prior to co-founding SignalFrame, Srdjan was in academia, at Imperial College London and ETH Zurich, focused on building secure systems founded in non-monotonic AI and formal methods.

  • Data Science Double Header: DevOps Lessons & Deploying ML in the Enterprise

    GWU, Funger Hall, Room 103

    Talk 1: Reflections on a Year Spent Talking to Data Scientists about DevOps As a Solutions Engineer at RStudio, I spend a good deal of time helping data scientists advocate for R within their organizations. These people are fully committed to ushering in better data practices and adopting the best tools and infrastructure for their team. Unfortunately, even highly motivated individuals can run into roadblocks when trying to get R recognized as an analytic standard. Commonly issues stem from a lack of management and governance around open source software; especially when IT is unfamiliar with requisite core competencies. In this talk, I present DevOps as a framework for understanding and navigating these kinds of organizational challenges. Kelly O’Briant is a solutions engineer at RStudio interested in configuration and workflow management with a passion for R administration. --------------------------- Talk 2: Deploying and Managing Machine Learning in Enterprise Environments You've Built and Trained a Model. Now What? An Overview of the ML lifecycle–what your company needs at every stage, from data collection to resource management, and how that impacts your deployment choices. We’ll then discuss custom deployment solutions from different industries and what you can learn from their success (and failures). Brendan Collins is the lead Solutions Engineer for Algorithmia’s east coast enterprise customers. He has worked in financial enterprise infrastructure for more than a decade, with groups ranging in size from the largest financial institutions in the world to community banks. Brendan has a true passion for helping enterprises use machine learning and data science to solve cutting edge problems, as well as a personal interest in serverless technologies of all shapes and sizes. Agenda ---------------------------- 6:30pm – 7:00pm Networking and Refreshments 7:00pm – 7:10pm Introduction, Announcements 7:15pm – 8:15pm Presentations and Q&A Join us for discussion and Data Drinks @ Tonic (2036 G St NW) following the event.

  • What We Know about the Quality of Data Used in Data Science

    GWU, Funger Hall, Room 103

    What We Know about the Quality of Data Used in Data Science Dr. Stephanie Eckman Abstract ----------------------------- The insights we get from data science models are only as good as the data that go into the models. Data can suffer from errors of representation (some cases are missing) and errors of measurement (the values in the data set are wrong). Both can cause problems for data scientists training models. I will discuss common data sources and the errors that we find in them. I will provide ideas on how we can address these errors to improve data science models. About the Speaker ----------------------------- Dr. Stephanie Eckman is a Fellow in the Survey Research Division at RTI International. She has a Ph.D. in Survey Statistics & Methodology from the Joint Program in Survey Methodology at the University of Maryland. She specializes in understanding data quality and the social construction of data. Agenda ---------------------------- 6:30pm – 7:00pm Networking and Refreshments 7:00pm – 7:10pm Introduction, Announcements 7:10pm – 7:40pm Presentation 7:40pm – 7:55pm Q&A 8:00pm – 8:30pm Data Drinks @Tonic (2036 G St NW)
