Questions and answers designated by tag: Online Learning

Can we use streaming data to train and use a model continuously and improve it at the same time?

Sunday, 15 March 2026 by razvansavin88

The ability to use streaming data for both continuous model training and real-time inference is a significant topic in machine learning, particularly within modern data-driven applications. The traditional approach to building machine learning models typically involves collecting a batch of data, cleaning and preparing it, training a model, evaluating it, deploying it, and then periodically

Why is machine learning still weak with streamed data (for example, trading)? Is it because of data (not enough diversity to get the patterns) or too much noise?

Wednesday, 25 February 2026 by razvansavin88

Machine learning's comparatively limited effectiveness with streamed data, particularly in high-frequency and financial trading contexts, derives from a combination of inherent data characteristics and structural limitations of current machine learning paradigms. Two central challenges are the nature of the data itself—specifically its high noise content and non-stationarity—and the technical demands of real-time adaptation and generalization

What are the key components of the editing interface when adding a new topic in LearnDash?

Monday, 19 August 2024 by EITCA Academy

The LearnDash WordPress LMS (Learning Management System) is a powerful tool designed to facilitate the creation and management of online courses. One of its key functionalities is the ability to add topics to lessons, which are essential for structuring course content in a pedagogically sound manner. When adding a new topic in LearnDash, the editing

What is ML?

Saturday, 02 September 2023 by Dawid Pytliński

Machine Learning (ML) is a subfield of Artificial Intelligence (AI) that focuses on the development of algorithms and models that enable computers to learn and make predictions or decisions without being explicitly programmed. ML algorithms are designed to analyze and interpret complex patterns and relationships in data, and then use this knowledge to make informed

What is the main advantage of using recurrent neural networks (RNNs) for processing sequential data?

Sunday, 13 August 2023 by EITCA Academy

Recurrent Neural Networks (RNNs) have gained significant attention in the field of Artificial Intelligence, particularly in the domain of processing sequential data. These networks possess a unique advantage over other types of neural networks when it comes to handling sequential data due to their ability to capture temporal dependencies and retain information from previous inputs.
