Machine Learning

What is Machine Learning ?

It is a term of Artificial Intelligence (AI) and Computer Science. Its main focal point is to use the data and algorithm
to emulate the way which learns humans and improving its accuracy gradually.

Machine Learning is an important component of data science. Algorithms are trained to generate classifications or predictions using statistical approaches, revealing crucial insights in data mining initiatives. Following that, these insights drive decision-making within applications and enterprises, with the goal of influencing important growth Key Performance Indicator (KPIs). 

As big data expands and grows, the demand for data scientists will rise, requiring their assistance in identifying the most relevant business questions and, as a result, the data needed to answer them.


Methods Of Machine Learning

Supervised machine learning

It describes the use of the labeled data to train the algorithms that accurately classify data or predict outcomes.
Its use of labeled data to train algorithms that accurately classify data or predict outcomes defines it. As more data is input into the model, the weights are adjusted until the model is properly fit. This happens during the cross-validation process to verify that the model does not overfit or underfit.

Unsupervised machine learning

The Unlabeled data are analyzed and clustered using machine learning algorithms. Without the need for human intervention, these algorithms uncover hidden patterns or data groupings. Because of its capacity to find similarities and
differences in data, it’s perfect for exploratory data analysis, cross-selling techniques, consumer segmentation, picture, and pattern recognition.
Principal component analysis (PCA) and singular value decomposition (SVD) are two common methodologies for reducing the number of features in a model through the dimensionality reduction process.
Neural networks, k-means clustering, probabilistic clustering approaches, and other algorithms are utilized in unsupervised learning.

Semi-supervised learning

Between supervised and unsupervised learning, semi-supervised learning is a good compromise. It facilitates classification and feature extraction from a larger, unlabeled data set using a smaller labeled data set during training. Semi-supervised learning can solve the problem of either not having enough labeled data to train a supervised learning method (or not being able to afford to label enough data).
