Overview of Sparse Modeling | Chan`s Jupyter
In this post, it will be explained about what the sparse modeling is and why this algorithm is used. This post is the summary of “Mathematical principles in Machine Learning” offered from UNIST
Overview of Sparse Modeling Sparse modeling Problem of Sparse Modeling Summary Overview of Sparse Modeling Sparse modeling The definition of sparse is come from the distribution. Sparse means something that is small number or amount and spread out over an area(or distribution). For example, sparse vectors and matrix have most of zeros and only a few number of non-zero valued elements. So why do we bring the concept of sparse to Machine Learning? Sparse modeling has advantages from training model. For example, consider about simple linear regression. y = θ 0 + θ 1 t + θ 2 t 2 + ⋯ + θ n t n y =
