Summary

A developer has implemented a Support Vector Machine (SVM) classifier from scratch in Rust, incorporating Sequential Minimal Optimization (SMO) for training. The implementation supports both linear and Radial Basis Function (RBF) kernels and utilizes grid search for hyperparameter tuning. Performance was evaluated on two datasets: the Banknote Authentication dataset, achieving 96% accuracy, 94% recall, and 95% F1 with a linear kernel; and the Breast Cancer dataset, yielding 93% accuracy, 100% recall, and 92% F1 with an RBF kernel. The project includes visualizations like PCA projections, highlighted support vectors, learning curves, and heatmaps, with the plotting utility "plot.rs" being AI-assisted.

Key takeaway

For AI Engineers or Machine Learning Engineers seeking to deepen their understanding of core algorithms, building an SVM from scratch in Rust offers significant learning. Your project should include robust optimization (like SMO), kernel support, hyperparameter tuning (grid search), and crucial visualizations to truly grasp the model's internal workings and debug effectively.
