Machine Learning (ML) is a part of Artificial Intelligence (AI) that gives the ability to computers or machines to read data even without any specific program. ML helps computers boost their performance on a particular task automatically through experience. It focuses on the way of using algorithms and data for imitating human beings in terms of how they learn while maintaining accuracy.
Machine Learning nowadays witnessed its growing use in multiple industries be it finance, healthcare, entertainment, and transportation. Some popular uses of this technology in these industries are fraud detection speech, image recognition, autonomous vehicles, recommender systems, and more.
The algorithm of ML heavily relies on statistics and mathematical optimization. Some of the popular ML libraries and frameworks are PyTorch, TensorFlow, and Scikit-learn.
How Machine Learning Works?
Machine Learning enables the machine to learn directly from data even without explicitly programming. In other words, ML involves creating an algorithm that can learn automatically and improve the overall experience.
The major purpose of ML is to develop an algorithm or mathematical model that learns directly from examples, identify relationships and patterns in the data, and use this kind of information for making decisions or prediction related to new data. To do this, the ML algorithm should be trained on a larger dataset, for example, popular as training data.
Let’s discuss here several steps of the process of training an ML algorithm. Take a look.
1. Data Collection
Data collection is the first and the most crucial step in an ML project. It involves the collection of relevant data to use for training and algorithms. Data comes from multiple sources including databases, sensors, online sources, etc.
2. Data Preparation
After the completion of data collection, you need to clean. Preprocessing is the best way for eliminating any kind of error from data. It also makes data free from any missing values and inconsistency. It also involves various other tasks including data normalization, dimensionality reduction, and feature selection.
3. Selecting Model
It’s another crucial step that involves the selection of the right ML algorithm that helps analyze the data. It also depends on the nature of the issue and also the type of data and desired results.
4. Training
After the selection of the right algorithm, the training process takes place. During the training phase, the algorithm makes certain adjustments in its internal parameters for reducing the actual differences between the actual and predicted output in the training data.
5. Evaluation
Once the training process is over, the overall performance of the algorithm is then determined on a separate dataset, which is popular as test data. It helps you assess the way the algorithm generalizes to new data.
6. Deployment
It’s the final step that involves deployment of the trained model for making decisions or predictions on new data.
Top 4 Types of Machine Learning
There are various types of Machine Learning algorithms. Each of the algorithms is available with its own set of strengths and weaknesses. Some of these algorithms are Supervised Learning, Unsupervised Learning, Semi-Supervised Machine Learning, and Reinforcement Learning. Let’s discuss each in detail.
1. Supervised Machine Learning
Supervised Machine Learning advocates the use of ‘labelled’ dataset to train the machine. In this, ‘labelled’ data indicates that some inputs are already influencing the output. In other words, Supervised Machine Learning involves training machines with the specific input corresponding to outcomes and then we use the machine for predicting output with the use of a test dataset.
We will take some examples here to understand Supervised Machine Learning. For instance, if you have some images of elephants as an input dataset, you should first train a machine to get a better understanding of images in terms of the shape and size of animals featured in images. The machine should understand the eyes’ shape, height, color, and tail of elephants.
After the completion of training, you can provide input as the image of an elephant. Now, the machine will check and analyze every important feature of the object, including color, shape, eyes, height, tail, etc., and then identify the animal as an elephant. In this process, ML identifies any items in supervised learning.
2. Unsupervised Machine Learning
Unsupervised Machine Learning is the opposite of Supervised Machine Learning. It doesn’t need supervision. In this, the unlabeled dataset is used to train the machine. It enables the machine to predict any kind of output even without any supervision.
The major purpose of unsupervised machine learning is to analyze the representation of the data that is meant to be for further visualization or analysis. Dimensionality reduction and clustering are the two important categories of Unsupervised Learning.
Let’s understand Unsupervised Machine Learning with an example. For instance, we use images of baskets full of fruit as input into an ML model. Since the input is new to the machine. So, the machine analyzes patterns and differences including shape, and color difference, and predicts the final output after testing it with the test dataset.
3. Reinforcement Machine Learning
In Reinforcement Machine Learning, agents generally interact with an environment for making a decision. And they receive either awards or penalties for their actions. This kind of machine learning involves learning the policy that can improve the cumulative reward over time.
Reinforcement Machine Learning is apt for robotics, game playing, and also for autonomous driving.
4. Semi-Supervised Learning
It’s another important type of machine learning that is in between Supervised ML and Unsupervised ML. It reflects the use of both unlabelled and labelled datasets when the training period takes place. Meanwhile, it mainly includes unlabeled data. The main goal of this type of ML is to use all the available data effectively.
