Classee demo

Easy Visualization of Classification Errors

Classification errors are usually evaluated with complex expert-oriented visualizations. The classee online tool offers simplified user-friendly visualizations, together with the traditional expert-oriented visualizations. It makes it easy to explore your classifier's performance, and communicate your results to end-users:
1. Upload your evaluation data
2. Explore and compare classifiers, datasets and parameters
3. Select the best visualization
4. Download your visualization
