The "Discover the secrets of the recommendation Engine" series will lead readers from shallow to deep learning to explore the mechanisms of the recommendation engine, which also involves some basic optimization methods, such as clustering and classification applications. At the same time, on the basis of theoretical ex

, including the mathematical model, various clustering algorithms and the implementation on different infrastructures. Through the code example, the reader can know the specific data problem for him, how to quantify the data, how to choose a variety of different clustering algorithms. The next article in this series will continue to delve into the relevant algorithms for the recommendation engine-classifica

advance, generally need to find an optimal K value through many experiments, and then, The algorithm is less tolerant to noise and outliers, since the algorithm initially adopts the method of randomly selecting the initial clustering center. Noise is the wrong data in a clustered object, and outliers are data that is far away from other data and less similar. For the K-means algorithm, once the outlier and noise are selected as the cluster center at the very beginning, the whole clustering proc

Zhang shaozhi said, "after you went back from the previous paragraph, we changed the system on your side and used it directly to the shangcong network.

Recommendation engine and learning 1. We can obtain suitable learning materials, and, importantly, we have the right to choose. We can respect the engine recommendation, or we can treat it as a breeze. 2. The premise of receng is to have enough information for learners. This means that computers can do better than hu

In my opinion, the voting mechanism is more in order to provide a better user experience, so that users can feel that they are "taking the lead" (in fact, they do not use voting, it is also possible to rank news by clicking rate ).The current Digg has added a recommend
