Making a good machine learning model involves more than just good data and well-selected features. Each model also has its own set of hyperparameters, variables which are set before training begins to influence how a given model learns. In this article, we go over grid search, a technique used to select the best hyperparameters for a model quickly and efficiently!

While two different malware samples might appear completely different to a human's evaluation, those same samples, stripped of their identities and reduced down to a vectorized representation of their most important qualities, might be found by a machine to have been twins all along. Insights like this are the goal of "clustering," a machine learning technique based on finding the similarities and differences across and between a massive amount of data points. What follows is an overview of one of those techniques, K-means.

Machine learning is one of the most versatile fields in all of computer science, with applications ranging from physics to art history, so, of course, it has a myriad of uses with regards to the detection and diagnosis of malicious programs; uses that we at InQuest would be remiss to not start utilizing ourselves. Here we go over some of the many ways ML algorithms are being leveraged for our purposes.
