In my August 2020 article, “How to decide on a cloud machine studying platform,” my first guideline for selecting a platform was, “Be near your information.” Protecting the code close to the information is important to maintain the latency low, for the reason that pace of sunshine limits transmission speeds. In spite of everything, machine studying — particularly deep studying — tends to undergo all of your information a number of occasions (every time via is known as an epoch).
I stated on the time that the perfect case for very giant information units is to construct the mannequin the place the information already resides, in order that no mass information transmission is required. A number of databases help that to a restricted extent. The pure subsequent query is, which databases help inner machine studying, and the way do they do it? I’ll talk about these databases in alphabetical order.
