“The Martian” is a science fiction novel written by Andy Weir and published in 2011. The story follows the journey of astronaut Mark Watney, who is left stranded on Mars after a violent storm forces his team to evacuate the planet. One of the key strengths of “The Martian” is the way it combines elements…

Stochastic gradient descent – We study the problem of stochastic gradient descent (SGD). SGD is a family of stochastic variational algorithms based on an alternating minimization problem that has a fixed solution and a known nonnegative cost. SGD can be expressed as a stochastic gradient descent algorithm using only a small number of points. In…

Learning Sparse Bayesian Networks with Hierarchical Matching Pursuit – We present a novel deep neural network architecture for predicting and ranking items by means of hierarchical matching pursuit. We propose a novel approach for ranking items by means of Hierarchical Matching Pursuit, which aims to approximate item ranking. Moreover, we extend our technique to the…
