What we're about

This virtual group is for data scientists, machine learning engineers, and open source enthusiasts.

Every month we’ll bring you two diverse speakers working at the cutting edge of data science, machine learning, AI and computer vision.

  • Are you interested in speaking at a future Meetup?
  • Is your company interested in sponsoring a Meetup?

Contact the Meetup organizers!

This Meetup is sponsored by Voxel51, the lead maintainers of the open source FiftyOne computer vision toolset. To learn more about FiftyOne, visit the project page on GitHub.

About the Workshop
Want greater visibility into the quality of your computer vision datasets and models? Then join Jacob Marks, PhD, of Voxel51 for this free 90 minute, hands-on workshop to learn how to leverage the open source FiftyOne computer vision toolset.

In the first part of the workshop we’ll cover:

  • FiftyOne Basics (terms, architecture, installation, and general usage)
  • An overview of useful workflows to explore, understand, and curate your data
  • How FiftyOne represents and semantically slices unstructured computer vision data

The second half will be a hands-on introduction to FiftyOne, where you will learn how to:

  • Load datasets from the FiftyOne Dataset Zoo
  • Navigate the FiftyOne App
  • Programmatically inspect attributes of a dataset
  • Add new sample and custom attributes to a dataset
  • Generate and evaluate model predictions
  • Save insightful views into the data

A working knowledge of python and basic computer vision. All attendees will get access to the tutorials, videos, and code examples used in the workshop.

Unleashing the Potential of Visual Data: Vector Databases in Computer Vision

Discover the game-changing role of vector databases in computer vision applications. These specialized databases excel at handling unstructured visual data, thanks to their robust support for embeddings and lightning-fast similarity search. Join us as we explore advanced indexing algorithms and showcase real-world examples in healthcare, retail, finance, and more using the FiftyOne engine combined with the Milvus vector database. See how vector databases unlock the full potential of your visual data.


Filip Haltmayer is a Software Engineer at Zilliz working in both software and community development.

Computer Vision Applications at Scale with Vector Databases

Vector Databases enable semantic search at scale over hundreds of millions of unstructured data objects. In this talk I will introduce how you can use multi-modal encoders with the Weaviate vector database to semantically search over images and text. This will include demos across multiple domains including e-commerce and healthcare.


Zain Hasan is a senior developer advocate at Weaviate, an open source vector database.

Reverse Image Search for Ecommerce Without Going Crazy

Traditional full-text-based search engines have been on the market for a while and we are all currently trying to extend them with semantic search. Still, it might be more beneficial for some ecommerce businesses to introduce reverse image search capabilities instead of relying on text only. However, both semantic search and reverse image may and should coexist! You may encounter common pitfalls while implementing both, so why don't we discuss the best practices? Let's learn how to extend your existing search system with reverse image search, without getting lost in the process!

Fast and Flexible Data Discovery & Mining for Computer Vision at Petabyte Scale

Improving model performance requires methods to discover computer vision data, sometimes from large repositories, whether its similar examples to errors previously seen, new examples/scenarios or more advanced techniques such as active learning and RLHF. LanceDB makes this fast and flexible for multi-modal data, with support for vector search, SQL, Pandas, Polars, Arrow and a growing ecosystem of tools that you're familiar with. We'll walk through some common search examples and show how you can find needles in a haystack to improve your metrics!


Jai Chopra is Head of Product at LanceDB

How-To Build Scalable Image and Text Search for Computer Vision Data using Pinecone and Qdrant

Have you ever wanted to find the images most similar to an image in your dataset? What if you haven’t picked out an illustrative image yet, but you can describe what you are looking for using natural language? And what if your dataset contains millions, or tens of millions of images? In this talk Jacob will show you step-by-step how to integrate all the technology required to enable search for similar images, search with natural language, plus scaling the searches with Pinecone and Qdrant. He’ll dive-deep into the tech and show you a variety of practical examples that can help transform the way you manage your image data.
