Supervised versus unsupervised learning: Which is best for you? Choosing the right approach for your situation depends on how your data scientists assess the structure and volume of your data, as well as the use case. To make your decision, be sure to do the following: Evaluate your input...

Supervised Learning (监督学习) 对具有概念标记(分类)的训练样本进行学习,以尽可能对训练样本集外的数据进行标记(分类)预测。这里,所有的标记(分类)是已知的。因此,训练样本的岐义性低。 监督学习是训练神经网络和决策树的最常见技术。这两种技术(神经网络和决策... ...
And here's another supervised learning example, in a breast cancer model, for each size of tumor in this data set, we told it which is malignant (恶性的) and which is benign (良性的), and the task of the algorithm was to try to predict of a new breast cancer as malignant or benign...

In contrast to supervised learning where data is tagged by an expert, e.g. tagged as a "ball" or "fish", unsupervised methods exhibit self-organization that captures patterns as probability densities or a combination of neural feature preferences encoded in the machine's weights and activations....
work behind the scenes earlier in the AI development lifecycle: It is often used to set the stage for the supervised learning's magic to unfold, much like the grunt work that enables a manager to shine. Both modes ofmachine learningare usefully applied to business problems, as explained ...
Unsupervised learning One way to distinguish between supervised/unsupervised learning is to find out the labels of your training set. For example, in the classic email spam case, "spam" or "ham" can be thought of as a label of your training set (emails). When a new email comes in, you...
