> Instead of giving the system whole words, they give the system the word in parts. For example, the word “hello” might be given as 4 word parts “he” “l” “l” “o”. This means we could learn a translation for the word “he” without the system ever having seen the word “he”.
Can anyone add context to this? Can't seem to wrap my head around this part. Doesn't "he" as a part of a word translate differently in different words?
