(Clustering)上,按照前面的说法,在 k-medoids 聚类中,只需要定义好两个东西之间的距离(或者 dissimilarity )就可以了,对于两个Profile ,它们之间的dissimilarity 可以很自然地定义为对应的N-gram 的序号之差的绝对值,在 Python 中用下面这样一个类来表示:class Profile(object): def __init__(self, path, N=...

K-median clusteringDropoutMachine learning era began to rule almost all the technologies, which influences the improvement of the performance due to its intelligent computing methodologies. Especially the Deep Learning algorithm plays a vital role in computing a human-like decision, which is considered ...
k-median clusteringData streamsThe focus of our work is introducing and constructing probabilistic coresets. A probabilistic coreset can contain probabilistic points, and the number of these points should be polylogarithmic in the input size. However, the overall storage size is also influenced by ...

In 2015, Driemel, Krivoija and Sohler introduced the ( k , )-median problem for clustering polygonal curves under the Fréchet distance. Given a set of input curves, the problem asks to find k median curves of at most vertices each that minimize the sum of Fréchet distances over all inpu...
