Page's configurations
Revision: Tracking the Evolution
In the realm of machine learning, iteration is key to refinement. With OtasML, each iteration of your machine learning model is termed a “revision.” These revisions capture the nuanced variations in model performance, reflecting the iterative nature of model training and evaluation.
Note: Embracing Iteration
In the ever-evolving landscape of machine learning, iteration is key to progress. With OtasML, each training session spawns a new revision, capturing the iterative journey of model development and evolution. This iterative approach ensures that users have a comprehensive view of their model's performance trajectory over time.
Chart Selection: Tailored Visualizations
The Chart section of the OtasML Results Page empowers users with the flexibility to choose from a diverse range of visual representations. Whether it's multiclass or binary classification, OtasML offers an array of charts tailored to your analytical needs. From Class-specific One-vs-Rest (OVR) Curves to Precision-Recall Curves, users can select the charts that best illuminate their model's performance landscape.
Multiclass Charts:
- Class-specific One-vs-Rest (OVR) Curve: Visualizes the performance of each class against all other classes.
- Micro-Average ROC Curve: Provides a combined ROC curve for all classes, weighted by the number of true positives for each class.
- Macro-Average ROC Curve: Illustrates the average performance across all classes, without considering class imbalance.
- Feature Importance: Displays the importance of different features in the classification process.
- Heatmap for Confusion Matrix (All Classes): Offers a visual representation of the confusion matrix for all classes.
- Main Diagonal of Confusion Matrix: Focuses on the diagonal elements of the confusion matrix, indicating correct classifications.
- Heatmap Confusion Matrix for a Specific Class: Zooms into the confusion matrix to highlight performance for a specific class.
