How Far You Can Get Using Machine Learning Black-Boxes [?]
Abstract:
Supervised Learning (SL) is a machine learning research area which aims at developing techniques able to take advantage from labeled training samples to make decisions over unseen examples. Recently, a lot of tools have been presented in order to perform machine learning in a more straightforward and transparent manner. However, one problem that is increasingly present in most of the SL problems being solved is that, sometimes, researchers do not completely understand what supervised learning is and, more often than not, publish results using machine learning black-boxes. In this paper, we shed light over the use of machine learning black-boxes and show researchers how far they can get using these out-of-the-box solutions instead of going deeper into the machinery of the classifiers. Here, we focus on one aspect of classifiers namely the way they compare examples in the feature space and show how a simple knowledge about the classifier’s machinery can lift the results way beyond out-of-the-box machine learning solutions.
Not surprising that understanding how to use a tool leads to better results. A reminder, particularly one that illustrates how to better use a tool, is always welcome.
