Machine learning

Machine learning is computer programming that uses a set of training data or experience to reach certain criteria or performance. Basically, machine learning focuses on the use of algorithms and data to imitate the way humans learn and eventually improving its accuracy. Machine learning is also part of artificial intelligence (AI) that involves a set of disciplines such as statistics, mathematics, computer science, and neurology. Basically, machine learning has few categories, such as supervised learning, unsupervised learning, and semi-supervised learning.

Supervised learning

Supervised learning or known as supervised machine learning is a practice that utilizes labeled datasets to train algorithms to be able to classify or predict things accurately. In general, supervised learning is studying the mapping function between input and output. This can be analogous to students learning something by studying a set of questions and the corresponding answer. After being able to map the questions and its answer, students can provide answers to new questions with the same topic.

Unsupervised learning

Unsupervised learning or known as unsupervised machine learning is a practice that utilizes unlabeled datasets to train algorithms to identify hidden patterns or create cluster data into groups with similar identifications. This means that the data can be identified based on the differences or the similarities for exploratory purposes. For example, unsupervised machine learning can cluster various books into groups based on the content within the book.

Semi-supervised learning

Semi-supervised learning or known as semi-supervised machine learning is a practice that utilizes the combination of supervised and unsupervised learning. This can be used when there is a combination of labeled and unlabeled datasets.

Neural network

The neural network is an algorithm model from machine learning that is inspired by how human brains work. It contains simple connected units or neurons that are followed by nonlinearities.

While the syntax of the closing tag starts with an opening angle bracket “<”, followed by a slash “/”, the element name, and closing angle bracket “>”.

HTML Element <html>

This element is the root of an HTML document. This <html> element should be added after the “!DOCTYPE”. And then, all the content or structure of an HTML document should be added between the opening and closing.
