Let’s get started!
What is Machine Learning?
Machine learning is a branch of artificial intelligence where machines are trained to make decisions and act intelligently without the intervention of humans.
Arthur Samuel, the father of machine learning defines it as “The field of study that gives computers the ability to learn without being explicitly programmed.” These machines can analyse tasks, figure out the decision and use the information for a better outcome.
Are you aware that you engage with machine learning daily?
Consider this: Have you ever wondered how Google Maps can predict the traffic accurately? How does it inform you about traffic on 12th Street due to ongoing metro construction? Google Maps uses real-time data to analyse the traffic, road conditions and patterns. Machine learning extracts information from geo-located imagery using a vast collection of images to make this possible!
Machine learning automates the process of learning from data. You give the data, it breaks the number, makes predictions or even takes actions without the need for constant reprogramming. It learns from new information and improves predictions over time.
Here is an interesting stat on Machine Learning. The market size of machine learning is projected to reach US $204.30 billion in 2024 and is expected to grow to US $528.10 billion in 2030 at a CAGR of 17.15%.
How Does Machine Learning Work?
Machine learning, a subset of AI, enables machines to improve their performance over time by learning from data. The process begins with feeding training data into the system, which helps the program learn and enhance its capabilities. The quality of this training data significantly influences the effectiveness of the machine learning process.
To evaluate performance, new input data is tested against the machine’s predictions. The program then compares these predictions with actual results to refine its accuracy. If there are discrepancies, the algorithm is adjusted and retrained until it achieves the desired outcomes. This iterative process allows the program to continuously learn and improve its predictions.
Types of Machine Learning
Machine learning can be broadly classified into three types based on the nature of the learning system and the available data: supervised learning, unsupervised learning and Semi-supervised learning. Let's explore each in detail:
1. Supervised Learning
In supervised learning, labelled data is used to train the program to recognise patterns and make predictions independently. The labelled dataset clearly defines the information the program should focus on and the type of result it should produce. This process involves mapping input to output data, allowing the algorithm to learn the relationship between them and improve prediction accuray.
Here the model is trained on the labelled dataset each having input and output parameters. The input data serve as clues or details whereas the output data represent the final targets.
Here are some of the top algorithms used in supervised learning:
- Random Forest
- Logistic Regression
- Naive Bayes
- Decision Trees
2. Unsupervised Learning
Unsupervised machine learning allows the model to learn from data without human intervention. It uses unlabelled data to find patterns and connections independently, without explicit instructions. The goal of unsupervised learning is to discover hidden patterns in the data. Unsupervised learning works by interpreting the hidden patterns and groups, then using those patterns to categorize new data. These algorithms find and extract useful information that results in better decision-making. These algorithms learn from the data and use the knowledge to create categories to group data.
The common use cases of unsupervised learning are:
- Fraud Detection
- Anomaly Detection
- Genetic Research
- Customer Segmentation
3. Semi-supervised Learning
Semi-supervised learning blends elements of both supervised and unsupervised learning. It leverages a small amount of labeled data to guide the learning process while using a larger set of unlabeled data to improve the model's effectiveness. This approach allows the program to analyze data, discover hidden patterns, and learn more efficiently.
The goal of semi-supervised learning is to combine the strengths of both methods, uncovering hidden patterns and generating valuable insights across various fields.
The real-life use cases include:
- Speech Analysis
- Image and Text Classification
- Internet Content Classification
