. After all, although set theory is the foundation of the entire mathematics, logical reasoning can be considered as the foundation of mathematics. First, streamline the logic and use logical symbols later to make other theories more concise.Finally, it is very effective to check whether your understanding of the knowledge is in place: General difficult questions. If you do, you will basically understand this knowledge point, if you don't know the answer, but you can understand it, it means you

Earlier, we mentioned supervised learning, which corresponds to non-supervised learning in machine learning. The problem with unsupervised learning is that in untagged data, you try to find a hidden structure. Because the examples provided to learners arenot marked, so there

Customer Churn "Loss rate" is a business term that describes the customer's departure or stop payment of a product or service rate. This is a key figure in many organizations, as it is usually more expensive to get new customers than to retain the existing costs (in some cases, 5 to 20 times times the cost). Therefore, it is invaluable to understand that it is valuable to maintain customer engagement because it is a reasonable basis for developing retention policies and implementing operational

see the geometrical meaning of the perceptual machine. A linear equation is the hyperplane of a separate space. where w is a normal vector of the plane (geometrically), B is its intercept. Training loss function In short, minimize the loss function. First, define (experience) loss functions (see the original book 2.2.2 P27 for detailed procedures):Loss function, which can be understood as an evaluation fun
