Quick Benchmark Colab CPU GPU TPU (XLA-CPU)


If you ever wonder about the performance differences between CPU, GPU, and TPU for your machine learning project, this article shows a simple benchmark for these three. Memory Subsystem Architecture Central Processing Unit (CPU), Graphics Processing Unit (GPU) and Tensor Processing Unit (TPU) are processors with a specialized purpose and architecture. CPU: A processor designed to solve every...

A really Cool data visualization: 3d globe in 2d space


While generating data in 3d space for manifold learning, I went across a problem of distributing points evenly on a sphere. It is a non-trivial problem but found a good enough solution for such placement. Interestingly, it ends up with a really cool animation effect when I decided to implement it on a mobile app. Figure 1: First animation effect: Rotation The algorithm There are two qualitatively...

TF2.0 Warm-up exercises (forked from @chipHuyen Repo)

Petamind A.I

Heard of Ms @huyen chip for her notable yet controversial travelling books back in the day. I enjoy reading but I am not really into travel┬ámemoirs. Nevertheless, she did surprise everyone by her achievements by getting in Stanford, teaching TensorFlow, and then became a computer/data scientist. Her story is definitely very inspiring. For ones who don’t know about Ms Huyen, I added an...

Game Frame rate and character animations (part 2)

In part 1, we covered the principle of game frame rate and a useful game programming pattern for performance. This part shows the detailed implementation of a game scene with hundreds of moving characters using Android Studio and Kotlin. Image asset This game uses a free image from wild-refuge.net. Xmas girl 3 (URL) You can download any similar image (4 x 4 frames) and place it in the...
