Accelerate your machine learning experimentation with FiftyOne

Better Data, Better Models

Good machine learning models require rapid iteration, and ML engineers need the right tooling to accelerate their projects. Backed by years of computer vision and machine learning research, our powerful tool FiftyOne helps you visualize and explore datasets, identify key scenarios, and evaluate model performance. Spend less time wrangling and more time on the science of building better ML models.

Train better models with
measurably better data

FiftyOne + ActivityNet

We've partnered with the team behind the ActivityNet dataset and challenge to make it easy to download, visualize, and evaluate this leading video understanding dataset directly in FiftyOne.

Training video understanding models is no simple task, so having access to the massive amounts of data that ActivityNet provides directly in FiftyOne will make it easier than ever for the computer vision community to build higher-quality video models. It's time to add a new dimension to your machine learning workflows with the ActivityNet dataset and temporal detection evaluation in FiftyOne!

FiftyOne + COCO

With support from the COCO team, FiftyOne is now a recommended tool for downloading, visualizing, and evaluating on the COCO dataset. COCO is one of the most popular large-scale object detection, segmentation, and captioning datasets in the world, and engineers and researchers can now easily work with it natively within FiftyOne.

Publicly available benchmark datasets are a key catalyst for machine learning advances. Boost the productivity of your workflows and insights into your experiments with COCO and FiftyOne today!

FiftyOne, meet Google

We're collaborating with Google to support Open Images, one of the largest publicly available annotated image datasets in the world. Engineers and researchers can easily download, visualize, and evaluate models using Open Images, all natively within FiftyOne.

Large, manually labeled datasets like Open Images drive the field of machine learning. Now with FiftyOne, future advances are more accessible than ever!
