**Introduction**

Unsupervised machine learning algorithms can be used to find hidden patterns in data. This article will explain how to implement an unsupervised machine learning algorithm using basic Python libraries.

**Unsupervised Machine Learning**

Unsupervised machine learning is a type of machine learning that focuses on identifying patterns in data without being told what to look for. It is the opposite of supervised machine learning, which requires a human to provide labels for the data.

Unsupervised algorithms are used to discover hidden relationships between variables, and they’re more likely than their supervised counterparts to find patterns that aren’t immediately apparent or intuitively obvious–like identifying your friend’s face in an image even though it may not have been labeled as such when you took the picture (and thus wasn’t considered by your system).

**Data Mining**

In this article, we will look at what data mining is and how it can be used to find hidden relationships between variables.

Data mining is a process of analyzing data to identify patterns, trends, and other useful information. Data mining is the process of discovering meaningful patterns in large data sets by looking for relationships and regularities among the variables.[1] This can be done by machine learning algorithms that learn from existing examples; these algorithms are known as “unsupervised” because no labeling of training data points by humans is required.[2]

**Theoretical Framework**

Theoretical Framework

Unsupervised machine learning is a type of data mining that seeks to identify hidden patterns in large datasets. Data mining involves using algorithms to uncover previously unknown relationships between variables, often times by analyzing large quantities of unstructured or semi-structured information such as text documents, images and social media posts. Unsupervised machine learning has many applications in business, medicine and science but it can also be used to discover hidden relationships between data points within your own personal life!

**Hidden Relationships**

Hidden relationships are the ones that aren’t obvious, but can still be discovered by a machine learning model. For example, you might be able to predict someone’s income from their age and gender. However if you are trying to predict whether or not someone will get married in the next year based on their age and gender alone, your model won’t be very good at this task because there’s no direct connection between marriage status and either of these variables (you’d need other information).

However if we were able to obtain additional data such as whether they were married before and how long they’ve been together in order for our model to make better predictions about future marriages!

**Identifying hidden patterns using k-means algorithm.**

In this section, we will be using the k-means algorithm to identify hidden patterns in data. The k-means algorithm is an unsupervised machine learning technique that clusters data points by grouping them into sets or clusters based on their similarity.

In this case, each cluster represents a different relationship between two variables (X and Y). It works by starting out with k random points (called initial centroids), then moving those points closer together until they form a tight group of similar values for X and Y. After doing this over and over again with different values for k (the number of desired clusters), it should converge on some optimal point where no more movement can occur within any given pair of values at any given time step during convergence – this is called “stationarity”.

**Identifying Hidden Patterns Using K-Means Algorithm**

K-Means is a popular clustering algorithm that allows you to define the number of clusters in your data and then finds them.

The k-means algorithm defines the number of clusters by specifying an initial centroid for each one, then iteratively updates these centroids until they converge on their final locations. The process can be visualized as follows:

**Data Preprocessing and Feature Selection**

Data preprocessing and feature selection are two important steps of data science. They help you to make the data ready for analysis, so that you can get better results from your model.

In this section, we will go through each of these steps in detail:

- Data cleaning – This step involves removing any unwanted characters from your dataset. For example, if there is any missing value in a column then it should be removed as well as converting all numbers into strings (for example “1” instead of 1). Also sometimes there might be some extra spaces at the end or beginning of a string which needs to be removed as well* Data formatting – You need to ensure that all numerical values should be formatted correctly before feeding them into machine learning algorithms.* Reduction – Reducing number of columns helps improve performance because fewer columns mean less computations required during training

**Unsupervised machine learning algorithms can be used to find hidden relationships in data.**

Unsupervised machine learning algorithms are used to find hidden patterns in data. Unsupervised learning is a type of machine learning where the algorithm learns from data without any labels or feedback.

These algorithms can be used to identify hidden relationships in your dataset, which may not be obvious at first glance but could still be useful for your business. There are many unsupervised machine learning algorithms available on the market today, including k-means clustering and principal component analysis (PCA).

**Conclusion**

The algorithm we used was k-means, which is a clustering algorithm that can identify hidden patterns in data. This algorithm works by grouping similar items together and then identifying clusters of items based on their similarities. The k-means algorithm uses Euclidean distance as its distance metric and randomly selects points (called centroids) within each cluster so that they’re all equidistant from each other (making them easy to find).
