Log loss. Log loss is one of the most commonly used classification metrics. It is also known as the cross-entropy loss. Classification algorithms usually output probability values for an observation belonging to a particular class.
Web09. apr 2024. · The main motivation for metric learning is that comparing two data points in input space is often meaningless and ambiguous (e.g. images of airplanes can be found to be similar due to blue sky and not to the plane itself), because you can't capture high-level (or semantic) features of the data. Web02. maj 2024. · Stated simply, the task of metric learning deals with optimization of a metric given a dataset and more often than not, the task is retrieval based i.e. given a datapoint, tell me which datapoints are the closest or farthest from the given datapoint. The notion of closest or farthest or proximity is essentially what the metric in metric ...
