Before building our neural network, we needed to get a better understanding of which input signal to use. Several approaches could have suited our goal here:
<ul>
<li>full-words from a user's posts caption and/or their bio and full-name</li>
<li>n-grams from a user's posts caption and/or their bio and full-name</li>
</ul>
The main problem here is that the input signal space is vast (set of all n-grams, or set of all words), and it is hard to design coherent fixed-sized input vectors (expected b
