Questions and answers designated by tag: Model Selection

How can I know which type of learning is the best for my situation?

Friday, 30 January 2026 by Javier Orduña

Selecting the most suitable type of machine learning for a particular application requires a methodical assessment of the problem characteristics, the nature and availability of data, the desired outcomes, and the constraints imposed by the operational context. Machine learning, as a discipline, comprises several paradigms—principally, supervised learning, unsupervised learning, semi-supervised learning, and reinforcement learning. Each

I have a question regarding hyperparameter tuning. I don't understand when one should calibrate those hyperparameters?

Monday, 17 November 2025 by Giacomo Rosso

Hyperparameter tuning is a critical phase in the machine learning workflow, directly impacting the performance and generalization ability of models. Understanding when to calibrate hyperparameters requires a solid grasp of both the machine learning process and the function of hyperparameters within it. Hyperparameters are configuration variables that are set prior to the commencement of the

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

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

When the reading materials speak about "choosing the right algorithm", does it mean that basically all possible algorithms already exist? How do we know that an algorithm is the "right" one for a specific problem?

Tuesday, 11 February 2025 by M.L. SAVI

When discussing "choosing the right algorithm" in the context of machine learning, particularly within the framework of Artificial Intelligence as provided by platforms like Google Cloud Machine Learning, it is important to understand that this choice is both a strategic and technical decision. It is not merely about selecting from a pre-existing list of algorithms

Which parameters indicate that it's time to switch from a linear model to deep learning?

Friday, 17 January 2025 by Alberto Della Libera

Determining when to transition from a linear model to a deep learning model is an important decision in the field of machine learning and artificial intelligence. This decision hinges on a multitude of factors that include the complexity of the task, the availability of data, computational resources, and the performance of the existing model. Linear
