I am a very beginner in the field of AI. I am basically a Pharma Professional without much coding experience. I use GUI based tools for the neural network.
I am trying to develop an ANN that receives as input a protein sequence and produces as output a drug molecule. Drug molecules can be represented as fixed-length binary (0-1). This length is 881 bit.
However, I do not know how to transform protein sequences of variable length into a fixed-length binary representation.
So, how should I deal with variable-length inputs for a neural network? What is the best way?
