# Encoder:
If you want to encode your sentence, use this command: encode(<your_sentence>)
Example:
Your Sentence: "ar ma"
Return: [[0.0, 0.6538461538461539], [0.46153846153846156, 0.0]]

# Decoder:
If you want to decode your encoded sentence, use this command: decode(<encoded_sentence>)
Example:
Your Encoded Sentence: [[0.0, 0.6538461538461539], [0.46153846153846156, 0.0]]
Return: "ar ma"
