Install GPU driver + CUDA + cuDNN + Tensorflow on Ubuntu 18.04
Installing Nvidia driver, CUDA, cuDNN, Tensorflow-gpu/Keras is not an easy task. We need to figure out how to match driver with hardware, match cuda/cudnn libraries versions(pretty complicated as known), and also need to make sure ML/DL frameworks(e.g., tensorflow) version can be compatible with the installed cuda version, etc. In this article w...

Understanding Principal Component Analysis (PCA)
During machine learning practice or data analysis, when we get a new dataset, what we can do first is to visualize the data to observe how the data distribute and what the relationship between datapoints. We can easily visualize dataset with 2 or 3 variables by plotting 2-demension(2D) or 3-dimension(3D) figure. However, most of the datasets hav...
