El rendimiento es un signo innegable de aprendizaje en una máquina. Cuando comienza a profundizar en este tema, solo un par de estos cambios se pueden clasificar como aprendizaje automático. En este audiolibro, aprenderá sobre el aprendizaje automático utilizando Python.

En las últimas décadas, se han desarrollado muchos lenguajes de programación, y solo algunos se han mantenido. Algunos ejemplos son C, que es un sistema operativo y de desarrollo de servidores popular para sistemas integrados. Cuando se trata de bases de datos, el lenguaje de consulta estructurado (SQL) ha existido desde la década de 1970.

Before going into the field of machine learning, we begin to answer the most important question. Why Python? The answer is simple: it is a powerful and accessible language. Python has become the most widely used programming language for data processing, since it allows you to neglect all the boring aspects of programming, offering an environment in which it is possible to put ideas into practice and see concepts in action.

SQL, pronounced ess-que-el, is a domain-specific language; this means that it is made for a certain purpose. Unlike general purpose languages like C++ or Ruby, SQL was made for a singular purpose, and to be excellent at that one purpose. It’s similar to the way HTML is designed to make web pages, and it falls into the same niche as much soft code. While alternatives to SQL like ISAM or VSAM exist, they have largely faded out of use due to SQL’s superiority. SQL is the pioneer of accessing N records with a singular command, and generally works without indexing.

If you look at it superficially, in respect to machines, it is safe to say that any change in the structure of the machine, the data stored in the memory or its data composition, in order to improve the efficiency and the effectiveness of the machine’s performance is an undeniable sign of learning in a machine. When you start to delve deeper into this subject, only a couple of these changes can be categorized as machine learning. 

In this audiobook, you will gather information about what SQL is and why it is important to learn SQL. This audiobook also covers some of the basic commands that are used in SQL and explains how you can use those commands to manipulate information in tables and datasets.
