Dictionary Learning is an important problem in multiple areas, ranging from computational neuroscience, machine learning, to computer vision and image processing. The general goal is to find a good basis for given data. More formally, in the Dictionary Learning problem, also known as sparse coding, we are given samples of a random vector y∈ℝⁿ, of the form y=Ax where A is some unknown matrix in ℝ^(n×m), called dictionary, and x is sampled from an unknown distribution over sparse vectors. The goal is to approximately recover the dictionary A.
