Hi,
I noticed that in label_encoder.txt file, the labels are encoded in a specific way:

'neu' => 0
'ang' => 1
'hap' => 2
'sad' => 3

'starting_index' => 0

I'm curious to understand the rationale behind this particular encoding scheme. Is there a specific reason why 'neu' is encoded as 0, 'ang' as 1, 'hap' as 2, and 'sad' as 3?

If anyone has insights on this encoding, I'd appreciate it.
