Spark MLlib Data Types Apache Spark Machine Learning
A local vector has integer-typed and 0-based indices and double-typed values, stored on a singlemachine. MLlib supports two types of local vectors: dense and sparse. A dense vector is backed bya double array representing its entry values, while a sparse vector is backed by two parallelarrays: indices and values. For … See more A labeled point is a local vector, either dense or sparse, associated with a label/response.In MLlib, labeled points are used in supervised learning algorithms.We use … See more A local matrix has integer-typed row and column indices and double-typed values, stored on a singlemachine. MLlib supports dense matrices, whose entry values … See more A distributed matrix has long-typed row and column indices and double-typed values, storeddistributively in one or more RDDs. It is very important to choose … See more WebSpark MLlib Data Types – RDD-based API Basically, Machine learning library supports many Data Types. Such as local vectors and matrices stored on a single machine. Similarly, … small glass containers for plants
