“Units” has been used in different context throughout the course?
Is this a personal thing or the tradition in the field?
Sometimes, neurons or nodes in a hidden layer are called “units”.
Then, in the current assignment “Using language as an example, a language with a 5000-word vocabulary could be one-hot encoded into a vector that has 5000 units”.
It is called “units” again! A vector does NOT have units!
Could the course make those terminology more consistent rather than confusing?
