Understanding Base58 encoding in Python
Converting binary to string can be useful when you need to represent a number in a recognizable, short package. For this task, Base64 is often used. Base64 contains characters that can be confused with each other. This can lead to transcription mistakes. It is also harder to copy & paste due to special characters. Base58…
How to Generate Text in Python
Text is my personal favorite medium for machine learning. Here is why: In computing, a picture is worth a (few hundred) thousand words. As a result, modeling text is more space and compute efficient than visual models. Text arrived first to the internet. This lead time has resulted in better algorithms, and bottomless data. Interpretability…
