Questions and answers designated by tag: Unsupervised Learning

What are some common AI/ML algorithms to be used on the processed data?

Tuesday, 01 July 2025 by Teemu Koivula

In the context of Artificial Intelligence (AI) and Google Cloud Machine Learning, the processed data—meaning data that has undergone cleaning, normalization, feature extraction, and transformation—is ready for machine learning algorithms to learn patterns, make predictions, or classify information. The selection of a suitable algorithm is driven by the underlying problem, the structure and type of

How does the choice of a machine learning algorithm depend on the type of a problem and the nature of data?

Saturday, 26 April 2025 by Mohammed Khaled

The selection of a machine learning algorithm is a critical decision in the development and deployment of machine learning models. This decision is influenced by the type of problem being addressed and the nature of the data available. Understanding these factors is important prior to model training because it directly impacts the effectiveness, efficiency, and

How does one know which ML model to use, prior to training it?

Tuesday, 15 April 2025 by Mafalda Paes de Carvalho

Selecting the appropriate machine learning model before training is an essential step in the development of a successful AI system. The choice of model can significantly affect the performance, accuracy, and efficiency of the solution. To make an informed decision, one must consider several factors, including the nature of the data, the problem type, computational

How do you decide which machine learning algorithm to use and how do you find it?

Sunday, 19 January 2025 by Jenni Hopeela

When embarking on a machine learning project, one of the major decisions involves selecting the appropriate algorithm. This choice can significantly influence the performance, efficiency, and interpretability of your model. In the context of Google Cloud Machine Learning and plain and simple estimators, this decision-making process can be guided by several key considerations rooted in

How long does it usually take to learn the basics of machine learning?

Friday, 10 January 2025 by Karol Siegmuller

Learning the basics of machine learning is a multifaceted endeavor that varies significantly depending on several factors, including the learner's prior experience with programming, mathematics, and statistics, as well as the intensity and depth of the study program. Typically, individuals can expect to spend anywhere from a few weeks to several months acquiring a foundational

Is there a type of training an AI model in which both the supervised and unsupervised learning approaches are implemented at the same time?

Thursday, 07 November 2024 by Preethi Parayil Mana Damodaran

The field of machine learning encompasses a variety of methodologies and paradigms, each suited to different types of data and problems. Among these paradigms, supervised and unsupervised learning are two of the most fundamental. Supervised learning involves training a model on a labeled dataset, where the input data is paired with the correct output. The

How is learning occurring in unsupervised machine learning systems?

Thursday, 07 November 2024 by Preethi Parayil Mana Damodaran

Unsupervised machine learning is a critical subfield of machine learning that involves training algorithms on data without labeled responses. Unlike supervised learning, where the model learns from a dataset containing input-output pairs, unsupervised learning works with data that lacks explicit instructions on the desired outcome. The primary goal in unsupervised learning is to identify hidden

What types of algorithms for machine learning are there and how does one select them?

Saturday, 12 October 2024 by Patrizia Bertini

Machine learning is a subset of artificial intelligence that focuses on building systems capable of learning from data and making decisions or predictions based on that data. The choice of algorithm is important in machine learning, as it determines how the model will learn from the data and how effectively it will perform on unseen

What are the different types of machine learning?

Monday, 22 July 2024 by Norman Carr

Machine learning (ML) is a subset of artificial intelligence (AI) that involves the development of algorithms that enable computers to learn from and make predictions or decisions based on data. Understanding the different types of machine learning is important for implementing appropriate models and techniques for various applications. The primary types of machine learning are

What are the key differences between reinforcement learning and other types of machine learning, such as supervised and unsupervised learning?

Tuesday, 11 June 2024 by EITCA Academy

Reinforcement learning (RL) is a subfield of machine learning that focuses on how agents should take actions in an environment to maximize cumulative reward. This approach is fundamentally different from supervised and unsupervised learning, which are the other primary paradigms in machine learning. To understand the key differences between these types of learning, it is
