Introduction to Unsupervised Learning

Unsupervised learning is a branch of machine learning that trains an algorithm to find patterns in a dataset without guidance or predefined labels. The objective is to model the underlying structure or distribution in the data to gain useful insights or patterns. The most common unsupervised learning tasks are clustering, association rule learning, and dimension reduction. Learn more about Artificial Intelligence, Machine learning, and Neural Networks.

Types of Unsupervised Learning

Primarily, unsupervised learning techniques can be divided into two categories: clustering and association rule learning. Clustering is the grouping of data points or objects that are similar to each other. This method is predominantly used to find hidden patterns or groups in data. Association Rule learning is a rule-based method for discovering interesting relations between variables in large databases.

Unsupervised Learning Algorithms

K-means Clustering: This algorithm partitions a data set into clusters or groups so that the data points in the same group are similar to each other than to those in other groups. Hierarchical Clustering: This method builds a hierarchy of clusters by either a bottom-up approach (agglomerative approach) or a top-down method (divisive method). DBSCAN: Density-Based Spatial Clustering of Applications with Noise (DBSCAN) is a density-based clustering algorithm, where groups of data points in the dataset are identified as high-density regions separated by regions of low density.

Applications of Unsupervised Learning

Unsupervised Learning has numerous applications, including social network analysis, market segmentation, astronomical data analysis, image recognition, and gene sequence analysis. E-commerce websites like Amazon use unsupervised learning for product recommendations.

Challenges in Unsupervised Learning

Unsupervised learning is a powerful tool for data analysis. However, it is more unpredictable than supervised learning as it lacks the guidance of labelled data. Interpreting the output is often difficult and uncertain. The quality of the output can be difficult to assess without subject matter experts.

Unsupervised Learning in Neural Networks

Unsupervised learning in neural networks is used to train machines to perform tasks by feeding them a huge amount of data. It aims to develop AI systems that can execute complex processing tasks similar to a human brain.

A Look at the Future of Unsupervised Learning

Earlier unsupervised learning was limited due to lack of computational power. The advent of Big Data and advanced hardware has allowed the application of unsupervised learning to vast and complex datasets. The future improvements in unsupervised learning algorithms will yield more powerful AI systems.


As Andrew Ng, a pioneer in the field of AI, once said, "AI is the new electricity".


What is Unsupervised Learning?

Unsupervised Learning is a type of machine learning that learns from test data that has not been labeled, classified or categorized.

What is the difference between Supervised and Unsupervised Learning?

In Supervised Learning, the model is trained on a labeled dataset, but in case of Unsupervised Learning, the model is trained on an unlabeled dataset.

Neural Computation: Bridging the Gap between Biology and Machine

Pivoting at the intersection of biology and computing lies the fascinating field of neural computation. Neural computation or neuro-computation refers to the computational systems and methodologies that are inspired by the functioning of the biological brain. The neural computation structure and functions are parallel to computational algorithms, demanding an in-depth understanding of biological information processing systems and artificial intelligence algorithms. We can understand the basis of neural computation through the complexity of the human brain. The human brain is an intricate web of approximately 86 billion neurons. These neurons interconnect through trillions of synapses, which are the pathways for signaling activities. This network, known as the neural network, is the powerhouse of functions such as cognition, learning, memory, and decision-making in humans. The biological neural networks serve as the inspiration behind the intricate structure of artificial neural networks Deep Learning: A Comprehensive Overview on ....

Era of Artificial Neural Networks

Computing revolution over the years led to the implementation of the neural computation concept in machines. The result was the birth of artificial neural networks (ANN). An artificial neural network is a computational model that mimics the functioning of neurons in the human brain. In an ANN, artificial neurons or nodes are interconnected via links. These links carry the numerical weights that manipulate the data as it passes through the network, like in a human neural network. Programmers teach ANNs through machine learning algorithms to solve complex computational problems in parallel. The more the network learns, the more sophisticated the problem it can solve. This has led to a rising trend of intelligent systems and technologies, including self-driving cars, automated chatbots, and artificial intelligence-driven software AI vs. Machine Learning vs. Deep Learning vs. Neural ....

From Neural Computation to Artificial Intelligence

Artificial Intelligence (AI) and Machine Learning (ML) rose from the principles of neural computation. AI is the broader concept of machines being able to carry out tasks intelligently. Machine Learning is its subset, which is the capability of machines to learn from data and improve themselves. Simultaneously, Deep Learning (DL) is a technique for implementing machine learning, drawing inspiration from how our brain functions. In essence, Neural computation is the brain behind AI, as the latter uses the principles of the former to learn and improve. Today deep learning, a part of AI, employs artificial neural networks with multiple abstraction layers. It results in the creation of patterns and structures for learning and decision-making by the machines What is AI? Everything to know about artificial intelligence.

Brain-based AI

The advancements in AI, riding on the carrier of neural computations, have transcended beyond computer-based neural networks. Scientists are trying to use biological neurons to power AI systems – the concept known as neuromorphic computing. As the name suggests, neuromorphic computing aims at morphing the human brain's computational abilities onto silicon chips. Brain-based AI's potential is transformative as it aims to overcome the limitations of artificial neural networks and traditional AI.


Neural computation is indeed an exciting cross-disciplinary field. From the complex computing of the human brain, to fueling the rise and development of artificial intelligence, its influence is far-reaching. With advancements in AI and the emergence of neuromorphic computing, we are inching closer to imitate the intricacies and efficiency of the human brain. Undoubtedly, the journey of neural computation, from the powerhouses of cognition in our brains to the technological marvels of AI, has been nothing short of fascinating.

Neural Computation FAQs

What is the role of Neural Computation in Artificial Intelligence?

Neural computation serves as the bedrock to develop artificial intelligence. By mimicking the human brain's computational techniques, AI can gain brains-like abilities to perceive, learn and make decisions. Different AI forms like machine learning and deep learning have emerged from neural computation principles.
