Invalid Responses
-----------------

Sometimes, the similarity algorithms may give a completely incorrect
answer that may lead to false response by the bot to the user. This is
because tensors have no resultant displacement and has multiple
direction. To compute zero vectors, SpaCy uses an approximation
algorithm called Word Mover Distance. This might lead to unknown
predictions. Such predictions should be raised as an issue on the
Sugaroid repository to create a tackler adapter that would override the
answer with a suitable confidence value.

The other complex and efficient algorithms have been neglected. This is
to reduce the size of the distribution as well as reduce the time of
installation on an end-user’s PC. Complex and accurate Natural Language
Processing systems like ``pytorch`` and ``tensorflow`` exists, but this
may result in the net user installation size to be approximately 2 GB +,
which is probably not what the end-user requires.
