Overfitting a dataset - Study guides, Class notes & Summaries

Data science - Correct Answers involves principles, processes, and techniques for understanding phenomena via the (automated) analysis of data Data-driven decision-making (DDD) - Correct Answers refers to the practice of basing decisions on the analysis of data, rather than purely on intuition. Big data - Correct Answers means datasets that are too large for traditional data processing systems, and therefore require new processing technologies. big data technologies - Correct Answers ar...

eal-life problems it is convenient to reduce the number of involved features (variables) in order to reduce the complexity, especially when the number of features is large compared to the number of observations. There are several criteria to tackle this variable reduction problem. Three of the most common are: maximization of the mutual information (MI) between the inputs and the outputs, minimization of the k-nearest neighbors (k-NN) leave-one-out generalization error estimate and minimiz...

What is deep learning? - an area of machine learning, focuses on deep artificial neural networks which are loosely inspired by brains. - Application: computer vision, speech recognition, natural language processing. Deep learning is a class of machine learning algorithms that:[10](pp199-200) - use a cascade of multiple layers of nonlinear processing units for feature extraction and transformation. Each successive layer uses the output from the previous layer as input. learn in supervised ...

Knowledge Base Question Answering for Space Debris QueriesSpace agencies execute complex satellite operations that need to be supported by the technical knowledge contained in their extensive information systems. Knowledge bases (KB) are an effective way of storing and accessing such information at scale. In this work we present a system, developed for the European Space Agency (ESA), that can answer complex natural language queries, to support engineers in accessing the information contain...
