<h1>Notation</h1>
<ul style="list-style: inside; padding-left: 0;">
<li>Any multiplication signs '*' mean elementwise multiplication (per NumPy, PyTorch, TensorFlow).</li>
<li>Any matrix style compound dot product will explicitly use MatMul() rather than '*' to avoid unacceptable notation ambiguity.</li>
<li>Any addition signs '+' mean elementwise addition, never the horrible notation abuse of concatenation.</li>
<li>All exp() and log() use the natural logarithm 2.718281828 (not base 10 or 2).</li>
<li>The pseudocode below uses a few undefined functions, but their trivial behavior should be obvious to implement. e.g. min, max, ones, zeroes, iif, assert</li>
<li>Data type field components are listed in logical bit order (not backwards right-to-left order).</li>
</ul>
