I always look back at these monthly reviews and I am always in awe on how much has been explored, discovered. This month is no exception (last month's review is at Nuit Blanche in Review (February 2014)). Among the many good surprises like the meetup speakers we hosted in Paris, here is another instance: Citing Nuit Blanche. A comment also led to this entry on thinking of the SKA as an Atmosphere Monitoring Station (more on that later). From the focused entries and implementations and meetups, the theme of the month was mostly about matrix decompositions and factorizations and their extensions in the tensor area and at the hardware level. As a result I updated the Advanced Matrix Factorization Jungle Page. But here are the implementations made available by their respective authors, enjoy!
