Abstract
U ovom radu korištene su generativne suparničke mreže kako bi se generirale nove sekvence peptida s antimikrobijskim svojstvima. Predstavljena je priprema podataka u kojoj su se postojeći antimikrobni peptidi morali pretvoriti u one-hot vektorski zapis. Klasičan model generatora izmijenjen je tako što mu je zadnji sloj bio podijeljen u 50 skupina po 21 neuron, te je za svaku skupinu korištena omekšana softmax aktivacijska funkcija. Za model diskriminatora je korišten obični klasifikacijski... More model. Model je uspješno istreniran, vidljiv je porast udjela generiranih antimikrobnih peptida kroz epohe, 56% nakon 5000 epoha, te čak 86% nakon 10 000 epoha. Analiza sekvenci pokazala je da su generirani peptidi kraći od peptida korištenih za trening, te je također vidljivo da se aminokiseline alanin (A), glicin (G), lizin (K), leucin (L) pojavljuje češće, iznad 10%. Dok se aminokiseline glutaminska kiselina (E), histidin (H), metionin (M), triptofan (W), tirozin (Y) pojavljuju rjeđe, ispod 1%. Less
Abstract (english)
In this thesis, generative adversarial networks were used to generate new peptide sequences with antimicrobial activity. Data preparation was presented in which existing antimicrobial peptides had to be converted to a one-hot vector record. The classic model of the generator was modified, the last network layer was divided into 50 groups of 21 neurons, and a softened softmax activation function was used for each group. An ordinary classification model was used for the discriminator... More model. The model has been successfully trained, the increase in the share of generated antimicrobial peptides through epochs is visible, 56% after 5000 epochs, and even 86% after 10 000 epochs. Sequence analysis showed that the generated peptides were shorter than the peptides used for training, and it was also seen that the amino acids alanine (A), glycine (G), lysine (K), leucine (L) occur more frequently, above 10 %. While the amino acids glutamic acid (E), histidine (H), methionine (M), tryptophan (W), tyrosine (Y) occur less frequently, below 1%. Less
