Oct 01, 2006 Conventional approaches to combining classifiers improve accuracy at the cost of increased processing. We propose a novel search based approach to automatically combine multiple classifiers in a cascade to obtain the desired tradeoff between classification speed and classification accuracy. The search procedure only updates the rejection thresholds (one for each constituent …
CASCARO : Cascade of classifiers with reject option3.1. Formulation of the cascade. We consider a classification problem with two classes (positive ″ 1 ″ and negative ″ 0 ″) and D variables {v 1, …, v D}. Let a training set of N examples {(x 1, y 1), …, (x N, y N)} where x i …
Feb 09, 2021 Although the lower layers of a deep neural network learn features which are transferable across datasets, these layers are not transferable within the same dataset. That is, in general, freezing the trained feature extractor (the lower layers) and retraining the classifier (the upper layers) on the same dataset leads to worse performance. In this paper, for the first time, we show that the ...

Nov 28, 2019 Hi I want to do hard negative mining for my trained cascade classifier. In other words, I want to add false positives to the list of negative images and re-train my cascade to improve accuracy. The question is: If the cascade detects a large region where a small portion of it is the desired object, then what should I do? The documentation says that negative images must not contain objects.
We propose a method to train a cascade of classifiers by simultaneously optimizing all its stages. The approach relies on the idea of optimizing soft cascades. In particular, instead of optimizing a deterministic hard cascade, we optimize a stochastic soft cascade where each stage accepts or rejects samples according to a probability ...

Jun 03, 2018 Cascade classifiers are, as th e name suggests, a concatenation of many classifiers. Each classifier forms a stage of the cascading pipeline and serves as a filter to weed out negatives. The classifiers get more and more complex as we move up the pipeline. Each complex classifier is made up of the basic classifiers below it in the pipeline.
