Point processes are finding growing applications in numerous fields, such as neuroscience, high frequency finance and social media. So classic problems of classification and …
Predictability is an emerging metric that quantifies the highest possible prediction accuracy for a given time series, being widely utilized in assessing known prediction algorithms and …
Bounding the best achievable error probability for binary classification problems is relevant to many applications including machine learning, signal processing, and information theory …
In the standard pipeline for machine learning model development, several design decisions are made largely based on trial and error. Take the classification problem as an example …
We propose a new splitting criterion for a meta-learning approach to multiclass classifier design that adaptively merges the classes into a tree-structured hierarchy of increasingly …
