Bodo DataFrames: HPC-based Drop-in Pandas Replacement
2025-11-20 12:00 - 13:00 UTC | https://openteams.com/event/bodo-dataframes-hpc-based-drop-in-pandas-replacement/
Pandas is a popular library for data scientists but it struggles with large datasets; programs either become too slow or run out of memory. In this talk, Ehsan Totoni (Bodo.ai) will introduce Bodo DataFrames as a drop-in replacement for the pandas library that uses high performance computing (HPC) based techniques such as Message Passing Interface (MPI) and JIT compilation for acceleration and scaling. Ehsan will give an overview of its architecture and explain how it avoids the problems of pandas (while keeping user code the same), go over concrete examples, and finally discuss current limitations. This talk is for pandas users who would like to run their code on larger data while avoiding frustrating code rewrites to other APIs.

Envisioning Stories with Generative AI
2025-09-18 12:00 - 13:00 | https://openteams.com/event/envisioning-stories-with-generative-ai/
What if your e-reader had an “illustrate” option to quickly depict any passage in a book as a visual scene? Generative AI can now readily transform content from one modality to another. This enables a story written in text form to be instantly transferred to visual form, potentially enhancing readers’ engagement with the story. In this talk, Dr. Roemmele discusses the research endeavor of automatically generating scene illustrations for text-based stories, outlining current AI techniques for this task and the challenges that persist. She will also demonstrate an example implementation of this proposed e-reader “illustrate” feature using accessible tools and model APIs.

Data Doesn't Lie, But it Can Mislead: How to Ensure Integrity of AI/ML Applications
2025-07-17 12:00 - 13:00 | https://openteams.com/event/data-doesnt-lie-but-it-can-mislead-how-to-ensure-integrity-of-ai-ml-applications/
A meaningful evaluation framework is crucial to the success of any Machine Learning (ML) application, yet structural biases often creep in unknowingly. When this happens, the results may not be as reliable as they initially appear…
This talk will identify common pitfalls and illustrate them with real-world examples from nearly two decades of experience in the data science field. We will explore the hidden story behind the performance metrics, moving beyond a single F-measure or accuracy score to delve into the intricacies of the data set and its domain. We’ll discuss how to identify artificial biases in your data and offer strategies for preventing them through rigorous design of your data collection and annotation processes.
Ultimately, this talk will provide a list of practical recommendations for building ML projects on solid foundations. Because amid the current AI boom and hype, we urgently need high-quality datasets, meaningful evaluations, and robust algorithms to ensure we are not just building elaborate sandcastles with GPUs.

Node.js: More Threads Than You Think
2025-02-20 12:00 - 13:00 | https://openteams.com/event/node-js-more-threads-than-you-think/
Node.js was announced in 2009 as a single-threaded JavaScript runtime. In 2018, it became multi-threaded, and no one noticed. What can worker_threads do? What are they useful for? What’s the best way of communicating between two threads? Scaling Node.js applications efficiently has long been a challenge for teams. Traditionally, Node.js runs on a single thread per service, meaning each instance operates as a single process within its container. This forces teams to overprovision infrastructure to handle unpredictable traffic spikes, leading to wasted resources and increased costs. The single-threaded nature of Node.js can pose performance risks; if a thread blocks its event loop due to a computationally heavy operation or a sudden traffic spike, it can cause downtime or degrade user experience. This raises a crucial question: How can teams optimize Node.js resource utilization to reduce costs without compromising performance or risking downtime? In this talk, we will explore multi-threaded Node, showing devs what they need to know to properly leverage multithreading.

JuliaSim: Building a Product Which Improves Open Source Sustainability
2025-01-16 12:00 - 13:00 | https://openteams.com/event/juliasim-building-a-product-which-improves-open-source-sustainability/
How do you prevent a “tragedy of the commons” and develop an ecosystem where maintainers of an open source project can thrive while continuing to support the community? In this talk, we will discuss JuliaSim, a product built by the developers from the Julia SciML open source organization in close collaboration with the Julia core compiler developers.
We will discuss how this product’s scope is defined to include the open source elements, how certain extensions to the open source are productized, but also how the release of much of the code as open has influenced and improved its business model.This discussion will highlight the complementary aspects of open source with startups
and serve as a discussion point as to the pros and cons of how open source can be anchored by non-academic communities.
