python workflow engine

This article is a series of tutorials in the first part of the tutorial on using the machine learning capability workflow from scratch in Python, covering algorithmic programming and other related tools from the start of the group. Will eventually become a set of hand-crafted machine language work packages. This time the content will begin with data preparation first.--from Matthew Mayo, KdnuggetsIt seems t

Before we talked about the Elasticsearch (search engine) operation, such as: Add, delete, change, check and other operations are used Elasticsearch language commands, like SQL command, of course Elasticsearch Official also provides a python operation Elasticsearch (search engine) interface package, just like the SQLAlchemy Operation database ORM box, so that we o

Inverted indexThe inverted index stems from the fact that a record needs to be found based on the value of the property. Each entry in this index table includes an attribute value and the address of each record that has that property value. Because the property value is not determined by the record, it is determined by the property value to determine the position of the record, and is therefore called an inverted index (inverted). A file with an inverted index is called an inverted index file (i
