In the course of learning and using Scikit-learn, two Ides (Canopy and Anaconda) were recommended in the official documentation, and I found Canopy was available after I installed it under Win7 and Mac respectively. Anaconda didn't understand how to use it. Win7 under the use of canopy also have some small twists and turns, but eventually can use, I think it is v

first, the conceptUnlike traditional clustering algorithms (such as K-means), the greatest feature of canopy clustering is that it is not necessary to specify the K value beforehand (that is, the number of clustering), so it has great practical application value. Compared with other clustering algorithms, canopy clustering, although the accuracy is low, but it has a great advantage in speed, so you can use
and find the center of the cluster, which can be greatly optimized?The efficiency of the K-means clustering algorithm. Next we will introduce another clustering method: canopy clustering algorithm.
The canopy clustering algorithm is a simple, fast, and accurate method for grouping objects into classes. Each object is represented by a point in a multi-dimensional feature space. This algorithm uses a fast
Canopy is an implementation of clustering algorithmIt is a fast, simple, but less accurate clustering algorithmCanopy calculates data by two artificially defined threshold t1,t2, which can be used to classify a bunch of chaotic data into N data heaps with a certain number of rules.Because the purpose of the canopy algorithm itself is to divide chaotic data into roughly several categories, it is less accurat

Kmeans is a classical algorithm in clustering, and the process is as follows:Select K points as the initial centroidRepeatAssigns each point to the nearest centroid, forming a K-clusterRecalculate the center of mass of each clusterUntil clusters do not change or reach the maximum number of iterations
The k in the algorithm needs to be artificially specified. There are a number of ways to determine k, such as multiple trials, calculation errors, the best K. This will take a long time. We can roug

(1) Set the sample set to S, determine two thresholds T1 and T2, and t1>t2.
(2) To take a sample point P belongs to S, as a canopy, recorded as C, remove p from S.
(3) Calculate the distance of all points to P in s Dist
