Do algebraic operations on neural networks. We seek here to implement
in R, operations on neural networks and their resulting approximations. Our operations derive
their descriptions mainly from
Rafi S., Padgett, J.L., and Nakarmi, U. (2024), "Towards an Algebraic Framework For Approximating Functions Using Neural Network Polynomials", <doi:10.48550/arXiv.2402.01058>,
Grohs P., Hornung, F., Jentzen, A. et al. (2023), "Space-time error estimates for deep neural network approximations for differential equations", <doi:10.1007/s10444-022-09970-2>,
Jentzen A., Kuckuck B., von Wurstemberger, P. (2023), "Mathematical Introduction to Deep Learning Methods, Implementations, and Theory" <doi:10.48550/arXiv.2310.20360>.
Our implementation is meant mainly as a pedagogical tool, and proof of concept. Faster implementations with
deeper vectorizations may be made in future versions.

Tay function

<dl><dt>f</dt>
<dd>the function to be Taylor approximated, for now "exp", "sin"
and "cos". NOTE use the quotation marks when using this argument.</dd>
<dt>n</dt>
<dd>The number of Taylor iterations. Accuracy as well as computation
time increases as \(n\) increases</dd>
<dt>q</dt>
<dd>a real number in \((2,\infty)\). Accuracy as well as computation
time increases as \(q\) gets closer to \(2\) increases</dd>
