41 label encoder python example

One hot encoding in Python - A Practical Approach - AskPython Here, the label 'apple' which is encoded as '0' would be having a binary vector as [1,0]. This is because the value 1 would be placed at the encoded index which is zero for apple (as seen in the label encoding of it). So, [apple, berry, berry] would be encoded as : [1, 0] [0, 1] [0, 1] Let us now implement the concept through examples.
