Face detection is a computer vision problem that involves finding faces in photos. It is a trivial problem for humans to solve and has been solved reasonably well by classical feature- based techniques, such as the cascade classifier. More recently deep learning methods have achieved state- of- the- art. In machine learning, we often use precision and recall instead of false positives and false negatives. Precision cascade classifier machine learning book pdf attempts to reduce false positives whereas recall attempts to reduce false negatives. They are both a decimal number, or fraction, between 0 and 1 where higher is better. Tuning the classifier.

Cascade of cascade classifier machine learning book pdf simple to complex classifiers that reject most non cascade classifier machine learning book pdf - faces with a few machine operations, 2) learning with a combination of boosting and haar features of extremely low complexity, and 3) use of bootstrapping to efficiently deal cascade classifier machine learning book pdf with the extremely l arge class of non- face examples. Cse 4404/ 5327 introduction to machine learning and pattern recognition j. Elder 5 discriminative classifiers!

If the conditional distributions are normal, the best thing to do is to estimate the parameters of these distributions and use bayesian decision theory to classify input vectors. Decision boundaries are generally quadratic. A classifier can also refer to the field in the dataset which is the dependent variable of a statistical model. For example, in cascade classifier machine learning book pdf a churn model cascade classifier machine learning book pdf which predicts if a customer is at- risk of cancelling his/ her subscription, the classifier may be a binary 0/ 1 cascade classifier machine learning book pdf flag variable in the historical analytical dataset, off of which the model was developed, which signals if the record has churned ( 1) or cascade classifier machine learning book pdf not. Cascade training¶ the next step is the training of classifier. As mentioned above opencv_ traincascade or opencv_ haartraining may be used to train a cascade classifier, but only the newer opencv_ traincascade will be described cascade classifier machine learning book pdf further. Command line arguments of opencv_ traincascade application grouped by purposes: common arguments: - data < cascade. The obtained tree- structure with groups of classifiers assigned to each of its nodes is called a cascade classifier. Given an incomplete information system with a hierarchical decision attribute d, we consider the problem of training classifiers describing values of d at its lowest granularity level. Object detection using haar feature- based cascade classifiers is an effective object detection method cascade classifier machine learning book pdf proposed by paul viola and michael jones in their paper cascade classifier machine learning book pdf rapid object detection using a cascade classifier machine learning book pdf boosted cascade of simple features in.
