Should you get the new NVIDIA DGX-1 for your startup/lab?

NVIDIA announced DGX-1, their new “GPU supercomputer”. The spec is impressive. Performance, even more so (training AlexNet in 2 hours with 1 node). Costs $129K. Running this would take around 3KW. That’s like keeping an oven going. The cheapest (per hour) best config you can currently get from AWS is g2.8xlarge: So for $129K you […]

Universal Function Approximation using TensorFlow

A multilayered neural network with even a single hidden layer can learn any function. This universal function approximation property of multilayer perceptrons was first noted by Cybenko (1989) and Hornik (1991). In this post, I will use TensorFlow to implement a multilayer neural network (also known as a multilayer perceptron) to learn arbitrary Python lambda expressions. (more…)
