Questions and answers designated by tag: Model Selection

Can more than 1 model be applied?

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

What are the rules of thumb for adopting a specific machine learning strategy and model?

Friday, 17 January 2025 by Alberto Della Libera

When considering adoption of a specific strategy in the field of machine learning, particularly when utilizing deep neural networks and estimators within the Google Cloud Machine Learning environment, several foundational rules of thumb and parameters should be considered. These guidelines help determine the appropriateness and potential success of a chosen model or strategy, ensuring that

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

Machine learning algorithms can learn to predict or classify new, unseen data. What does the design of predictive models of unlabeled data involve?

Thursday, 24 August 2023 by Wojciech Cieslisnki

The design of predictive models for unlabeled data in machine learning involves several key steps and considerations. Unlabeled data refers to data that does not have predefined target labels or categories. The goal is to develop models that can accurately predict or classify new, unseen data based on patterns and relationships learned from the available

What is the definition of a model in machine learning?

Thursday, 10 August 2023 by Brian Buckley

A model in machine learning refers to a mathematical representation or algorithm that is trained on a dataset to make predictions or decisions without being explicitly programmed. It is a fundamental concept in the field of artificial intelligence and plays a important role in various applications, ranging from image recognition to natural language processing. In

How does the choice of K affect the classification result in K nearest neighbors?

Monday, 07 August 2023 by EITCA Academy

The choice of K in K nearest neighbors (KNN) algorithm plays a important role in determining the classification result. K represents the number of nearest neighbors considered for classifying a new data point. It directly impacts the bias-variance trade-off, decision boundary, and the overall performance of the KNN algorithm. When selecting the value of K,
