}A machine is a device assembled from various metal and non-metal parts. It consumes energy and can operate and perform work. It is used to replace human labor, perform energy conversion, information processing, and produce useful work. Machines have been present throughout human history. But the real "machine" in modern times was gradually invented after the Western Industrial Revolution.

Build machine learning models with PySpark ML09Apr2023
Spark is an open source framework designed for interactive querying, machine learning, and real-time workloads, and PySpark is a library for Python using Spark. PySpark is an excellent language for performing exploratory data analysis at scale, building machine learning pipelines, and creating ETL for data platforms. If you're already familiar with libraries like Python and Pandas, PySpark is a great language to learn and create more scalable analyzes and pipelines. The purpose of this article is to show how to build a machine learning model using PySpark. Conda creates a python virtual environment conda will almost all
Summary of machine learning hyperparameter tuning (PySpark ML)08Apr2023
An important task in ML is model selection, or using data to find the best model or parameters for a given task. This is also called tuning. You can tune a single estimator, such as LogisticRegression, or an entire pipeline that includes multiple algorithms, characterizations, and other steps. Users can tune the entire Pipeline at once, rather than tuning each element in the Pipeline individually. An important task in ML is model selection, or using data to find the best model or parameters for a given task. This is also called tuning. A single Estimator (such as LogisticRegression) can be tuned, or
