Questions and answers designated by tag: Data Science

What basic differences exist between supervised and unsupervised learning in machine learning and how is each one identified from the first examples of a course?

Thursday, 09 October 2025 by JOSE ALFONSIN PENA

Supervised and unsupervised learning constitute two fundamental approaches in machine learning, each characterized by the nature of the data they operate on and the objectives they pursue. An accurate understanding of their basic differences is vital when embarking on any study or practical implementation of machine learning systems, particularly within educational courses that introduce foundational

What and where is the intelligence in machine learning?

Friday, 19 September 2025 by Youshan YU

The concept of intelligence in machine learning (ML) is frequently discussed yet often misunderstood. To provide a thorough answer, it is critical to clarify what "intelligence" signifies in the context of machine learning, trace where it resides within ML systems, and illustrate its manifestations with practical examples, particularly within the context of modern cloud-based platforms

What’s state-of-the-art machine learning capable of doing now?

Tuesday, 02 September 2025 by joelprata@gmail.com

Machine learning, as implemented in contemporary cloud platforms such as Google Cloud, operates as an advanced computational methodology that enables systems to identify patterns, make predictions, and adapt to new data without explicit reprogramming. At this very moment, machine learning is actively transforming vast volumes of raw data into actionable insights across multiple industries and

What is the difference between machine learning and data science?

Tuesday, 22 July 2025 by Jérôme Vincq

The distinction between "machine learning" and "data science" is foundational yet frequently misunderstood in the fields related to artificial intelligence and analytics, especially when considering applications within platforms such as Google Cloud Machine Learning. Understanding the boundaries and intersections between these two concepts is important for professionals and students seeking clarity on their respective roles,

Why should one use a KNN instead of an SVM algorithm and vice versa?

Saturday, 12 July 2025 by George Tsolakis

When evaluating whether to employ the k-Nearest Neighbors (KNN) algorithm or the Support Vector Machine (SVM) algorithm for a machine learning task, several critical aspects must be considered, including the theoretical underpinnings of each algorithm, their practical behavior under varying data conditions, computational complexity, interpretability, and the specific requirements of the application domain. Each algorithm

Why is regression frequently used as a predictor?

Wednesday, 21 May 2025 by kenlpascual

Regression is commonly employed as a predictor within machine learning due to its foundational capacity to model and forecast continuous outcomes based on input features. This predictive capability is rooted in the mathematical and statistical formulation of regression analysis, which estimates the relationships among variables. In the context of machine learning, and particularly in Google

Can more than one model be applied during the machine learning process?

Tuesday, 13 May 2025 by Mark Macedo

The question of whether more than one model can be applied during the machine learning process is highly pertinent, especially within the practical context of real-world data analysis and predictive modeling. The application of multiple models is not only feasible but is also a widely endorsed practice in both research and industry. This approach arises
