How do ML algorithms learn to optimize themselves so that they are reliable and accurate when used on new/unseen data?
Machine learning algorithms achieve reliability and accuracy on new or unseen data by a combination of mathematical optimization, statistical principles, and systematic evaluation procedures. The learning process is fundamentally about finding suitable patterns in data that capture genuine relationships rather than noise or coincidental associations. This is accomplished through a structured workflow that involves data
At which point in the learning step can one achieve 100%?
In the context of machine learning, particularly within the framework provided by Google Cloud Machine Learning and its introductory concepts, the question of "At which point in the learning step can one achieve 100%?" brings forth important considerations regarding the nature of model training, validation, and the conceptual understanding of what 100% refers to in
What is the biggest bias in Machine Learning?
In machine learning, the concept of "bias" encompasses several nuanced meanings, but when addressing the largest or most significant bias in machine learning, particularly in the context of practical applications and system deployment, data bias—or more specifically, training data bias—stands out as the most profound and impactful form. This type of bias is intricately connected
How does an ML model learn from its reply? I know we sometimes use a database to store replies. Is that how it works, or are there other methods?
Machine learning (ML) is a subset of artificial intelligence that enables systems to learn from data, identify patterns, and make decisions or predictions with minimal human intervention. The process by which an ML model learns does not involve simply storing its replies in a database and referencing them later. Rather, ML models utilize statistical methods
Is in-sample accuracy compared to out-of-sample accuracy one of the most important features of model performance?
In-sample accuracy compared to out-of-sample accuracy is a fundamental concept in deep learning, and understanding the distinction between these two metrics is of central importance for building, evaluating, and deploying neural network models using Python and PyTorch. This topic directly relates to the core objective of machine learning and deep learning: to develop models that
