What is W&B Experiments?
W&B Experiments lets you quickly and easily implement experiment logging by adding just a few lines to your script and start logging results. Our lightweight integration works with any Python script.
Problem
Data scientists and ML engineers currently rely on manual tracking methods like spreadsheets or local logs to record machine learning experiments, leading to inefficient collaboration and difficulty reproducing results.
Solution
A developer tool (Python library + dashboard) that lets users automate experiment tracking with minimal code, enabling real-time logging of metrics, hyperparameters, and outputs for machine learning workflows (e.g., logging training loss with 2 lines of code).
Customers
Data scientists and machine learning engineers working on iterative model training, particularly in teams requiring reproducibility and centralized experiment analysis.
Unique Features
Lightweight, framework-agnostic integration requiring only a few lines of Python code; centralized dashboard for comparing runs across datasets, models, and parameters; automatic versioning of code and artifacts.
