This article is an introductory guide on implementing machine learning with CARET in R. It includes Data splitting, Pre-processing, Feature selection etc.
Random Forest algorithm for genomic selection. Random Forest Therandom forest algorithmis a classifier consisting in many random decision trees. It is based on choosing random subsets of variables for each tree and using the most frequent, or the averaged tree output as the overall classification. ...
Classification accuracy will be used to evaluate each model. These behaviors are provided in the cross_validation_split(), accuracy_metric() and evaluate_algorithm() helper functions. We will use the predict() and train_weights() functions created above to train the model and a new perceptron(...
aA commonly used classification algorithm, the center vector method is simple and fast. A Bayesian method of training process and classification process is based on the probability model, with easy to implement, the advantages of faster classification. But it needs the assumption of independence in ...
The property of H.264/AVC CAVLC(context-adaptive variable-length coding) and the characteristic of Huffman Coding are analyzed, and a high efficiency implement algorithm of CAVLC decoding based on codeword classification mapping is proposed in this paper. According to the characteristic of Huffman Co...
If we use the same algorithm to predict the click through rate of the 3rd season of iPinYou, the overall AUC will be 0.77 which is comparable to the overall AUC of the 3rd season 0.76 reported in (Zhang, Yuan, Wang, et al., 2014). ...
Implementing a machine learning algorithm in code can teach you a lot about the algorithm and how it works. In this post you will learn how to be effective at implementing machine learning algorithms and how to maximize your learning from these projects. ...
