Is machine learning a loose collection of disciplines and tools?

Indeed, machine learning can be reasonably characterized a loose collection of disciplines and tools. where the lines begin that separate machine learning from statistics or mathematics or probability theory or any other handful of fields that it draws on are not clear.

What are the practical objectives of machine learning?

The main practical objectives of machine learning consist of generating accurate predictions for unseen items and of designing efficient and robust algorithms to produce these predictions, even for large-scale problems. to do so, a number of algorithmic and theoretical questions arise.

What is the concept of machine learning?

The goal of machine learning is to train machines to get better at tasks without explicit programming.
to achieve this goal, several steps have to take place.
first, data needs to be collected and prepared.
then, a training model, or algorithm, needs to be selected.

What is ML and its application?

Machine learning is an application of artificial intelligence that uses statistical techniques to enable computers to learn and make decisions without being explicitly programmed.
it is predicated on the notion that computers can learn from data, spot patterns, and make judgments with little assistance from humans.

these models are used for a wide range of purposes, including identifying specific plants, landmarks, and even individuals from photographs.
some common applications that use machine learning for image recognition purposes include instagram, facebook, and tiktok.

How machine learning can improve the intelligence of an application?

Besides, the deep learning, which is part of a broader family of machine learning methods, can intelligently analyze the data on a large scale. in this paper, we present a comprehensive view on these machine learning algorithms that can be applied to enhance the intelligence and the capabilities of an application.

What are the basics of machine learning?

But before doing so, let's look into some basics in machine learning you must know to understand any sorts of machine learning model. there are three main ways models can learn: reinforcement learning: algorithms learn via action feedback. in machine learning, whenever you are training a model you always must evaluate it.

What are the applications of machine learning?

To collect the data in the relevant domain, such as cybersecurity, iot, healthcare and agriculture discussed in sect. “ applications of machine learning ” is not straightforward, although the current cyberspace enables the production of a huge amount of data with very high frequency.

Top 10 Applications of Machine Learning  Machine Learning Applications & Examples  Simplilearn

Classification analysis

Classification is regarded as a supervised learning method in machine learning, referring to a problem of predictive modeling as well, where a class label is predicted for a given example . Mathematically, it maps a function (f) from input variables (X) to output variables (Y) as target, label or categories

Regression analysis

Regression analysis includes several methods of machine learning that allow to predict a continuous (y) result variable based on the value of one or more (x) predictor variables

Cluster analysis

Cluster analysis, also known as clustering, is an unsupervised machine learning technique for identifying and grouping related data points in large datasets without concern for the specific outcome

Dimensionality reduction and feature learning

In machine learning and data science, high-dimensional data processing is a challenging task for both researchers and application developers

Association rule learning

Association rule learning is a rule-based machine learning approach to discover interesting relationships, “IF-THEN” statements, in large datasets between variables . One example is that “if a customer buys a computer or laptop (an item), s/he is likely to also buy anti-virus software (another item) at the same time”

Reinforcement learning

Reinforcement learning (RL) is a machine learning technique that allows an agent to learn by trial and error in an interactive environment using input from its actions and experiences. Unlike supervised learning, which is based on given sample data or examples, the RL method is based on interacting with the environment

Artificial neural network and deep learning

Deep learning is part of a wider family of artificial neural networks (ANN)-based machine learning approaches with representation learning. Deep learning provides a computational architecture by combining several processing layers, such as input, hidden, and output layers, to learn from data
