LEXICAL REPRESENTATION OF DENSE NUMERICAL VECTORS: INTRODUCING LANGVEC
High-dimensional numerical vectors are widely used in machine learning for searching and indexing data. However, it is often difficult for users to interpret their meaning. To address this, we introduce a novel approach that transforms dense vectors into human...

DOUBLE COUNTING AND FIBONACCI NUMBERS
The article proposes a double counting method for proving combinatorial identities involving Fibonacci numbers. The method is easily remembered by the students. It allows them to apply it creatively in many situations, by (re)discovering the results by themsel...
