What Is Machine Learning? Machine Learning Algorithms and Implementation


In this post, you will learn what machine learning is and how it works. You will also learn about the different types of machine learning algorithms used to build intelligent systems.

What is machine learning?

Machine learning is a type of artificial intelligence that uses algorithms to build intelligent systems. It’s a subfield of computer science, which means it can be used to solve problems that are too complex for humans to solve.

Machine learning has been around since the 1950s and became popular after IBM created Deep Blue–the first chess-playing computer–in 1996. Today, machine learning is used in many industries including finance and healthcare to improve decision making processes by analyzing large amounts of data (i.e., big data).

Machine Learning Algorithms

Machine learning algorithms are used to make predictions based on data. There are many different types of machine learning algorithms, but the most popular ones are supervised and unsupervised learning.

Supervised Learning: With this type of algorithm, you have a training set (also known as a labeled dataset) that contains examples of what your model should be able to recognize in order for it to be useful in real-world situations. For example, let’s say you want your model to learn how to recognize images of cats and dogs rather than just any animal or object. You’ll provide an example image along with its corresponding label (e.g., “cat”) so that when other images come along later on during testing time, they can be quickly sorted into categories based on their similarity with previous examples — this will allow systems like Amazon’s Alexa voice assistant service or Google Assistant smartphone app accessibly recognize what users ask them without needing any additional information beyond what was provided during training time


Classification is a supervised learning technique used to predict the class of new data. It learns from existing examples to classify future instances into one of several predefined categories.

Classification algorithms are typically used for regression problems, where you want to predict continuous values such as stock prices or house prices based on historical data. However, they can also be applied to binary classification tasks (e.g., spam vs non-spam emails).


Regression is a supervised learning algorithm that attempts to find a relationship between two variables. Regression can be used to predict future values of a variable, or it can be used to fit the data points within an existing relationship.

The most common regression algorithms are linear regression and logistic regression (or “logit”). Linear regression attempts to find an equation that best fits your data points, while logistic regression predicts categorical outcomes instead of numerical values.

Supervised Learning

Supervised learning is the most common form of machine learning, and it’s used to predict a continuous output.

In supervised learning, you have labeled training data that you can use to train your model. This means that you have both the inputs and their corresponding outputs for all of your examples in this dataset (i.e., there are no missing values). The goal is then for our model to learn from these examples so that it can make accurate predictions on new data where we don’t know what exactly happened in advance–this is called unsupervised or semi-supervised learning instead!

Unsupervised Learning

Unsupervised learning is a type of machine learning where the algorithm is not given any target output. Unsupervised algorithms are used to find hidden patterns in data, and are useful for data exploration and feature selection. The following are some examples of unsupervised learning:

  • clustering algorithms–these group similar items together based on their similarities
  • dimensionality reduction–this reduces the number of variables used to describe data points

Machine learning is a powerful tool that can be used to build intelligent systems. It is a subfield of artificial intelligence (AI), which is a subfield of computer science. Machine learning is about building computer programs that can learn from data without being explicitly programmed.

The goal of machine learning is to develop algorithms that allow computers to improve their performance on a specific task by themselves, with little human intervention or supervision.

No It Doesn't! Seriously, What Is "Crypto"?

Wed Oct 19 , 2022
Introduction Cryptography is the art and science of encoding and decoding information in order to send it securely. The word “crypto” means hidden, so cryptography is the practice of hiding information in such a way that only authorized parties can access it. Cryptography has been around for thousands of years; […]
