Hadoop streaming is a multi-language programming tool provided by Hadoop that allows users to write mapper and reducer processing text data using their own programming languages such as Python, PHP, or C #. Hadoop streaming has some configuration parameters that can be used to support the processing of multiple-field text data and participate in the introduction and programming of Hadoop streaming, which can be referenced in my article: "Hadoop streaming programming instance". However, with the H ...

Sally is a tool that maps a set of strings to a set of vectors. The mapping is referred to as embedding, and allows machine learning and data mining techniques to be applied to string data analysis. It can be used for data such as text files, DNA sequences, or log files. It uses a vector space model or a bag-of-words model, and the string is through a set of attributes, each of which is associated with one aspect of the vector space. In addition, binary or TF values can be computed, vectors can be exported as plain text, LIBSVM or MATLAB format. Sal ...
