Question 1

How do I train a classification model with node-svm?

Accepted Answer

Initialize a classifier like CSVC with your dataset, use the train method with options for automatic parameter tuning. The README provides examples with XOR and other datasets to get started quickly.

Question 2

node-svm vs TensorFlow.js for support vector machines?

Accepted Answer

node-svm is specialized for SVMs with direct LIBSVM bindings, offering robust, optimized SVM features. TensorFlow.js has broader ML capabilities but may not have as fine-tuned SVM implementation. Choose based on your project's focus and stack.

Question 3

What causes segmentation faults in node-svm and how to fix them?

Accepted Answer

Segmentation faults often occur with empty, incorrectly formatted, or very large datasets. Ensure data is properly structured as arrays, and consider reducing dataset size or using sampling techniques to avoid memory issues.

Question 4

Can I use node-svm for real-time predictions in a Node.js server?

Accepted Answer

Yes, but be mindful of performance overhead from C++ bindings. For high-frequency requests, optimize by caching trained models and minimizing data preprocessing steps to reduce latency.

Question 5

How to perform cross-validation with node-svm?

Accepted Answer

Set the kFold parameter in the options to enable k-fold cross-validation during training. This helps evaluate model accuracy and prevent overfitting, as described in the parameters section with kFold defaults.

Question 6

node-svm or scikit-learn for a machine learning project?

Accepted Answer

If you're committed to Node.js, node-svm is ideal for SVMs. For Python, scikit-learn offers a more comprehensive ML suite. The decision hinges on your tech stack and need for ecosystem integrations.
