unsupervised machine learning造句

• To detect a novel type of fraud may require the use of an unsupervised machine learning algorithm.
• "' Unsupervised machine learning "'is the machine learning task of inferring a function to describe hidden structure from unlabeled data.
• Newer systems combining unsupervised machine learning with full network traffic analysis can detect active network attackers from malicious insiders or targeted external attackers that have compromised a user machine or account.
• A support vector machine can be used for supervised machine learning, in which training set of already classified data is available, or unsupervised machine learning, in which all data given to the system is unclassified.
• A subset of unsupervised machine learning, the Expectation maximization algorithm is utilized to iteratively estimate the a posterior probabilities and distributions of labeling when no training data is available and no estimate of segmentation model can be formed.
