"a" and "an" when using the forward slash punctuation mark

I was recently writing about a concept in computer science called a ‘perceptron’, otherwise known as an ‘artificial neuron’. I asked the following question:

Where does the so-called ‘loss’ / ‘loss function’ fit into the idea of a perceptron / artificial neuron (as presented in the figure)?

The part of interest is

a perceptron / artificial neuron

"a perceptron" is valid grammar, but "a artificial neuron" would be invalid (it should be an artificial neuron). Is it still correct/valid English to write "a perceptron / artificial neuron" when using the forward slash punctuation mark? If not, then how should it be worded?
