| <p>Also, I should mention, SVM is a great way to not only build functions,<br />
but also visualise higher dimensions in 2D space:<br />

<p>Yes, overfitting is a concern. But that will happen with 2 or 8 or 80 features if you have only a limited qty of triggers (events). Decreasing features does does not decrease overfitting. Only increasing the qty of events improves this condition.<br />
You can use cross-validation to compensate. This shuffles small dataset into larger, safer datasets:<br />
