Recently, the research for Antimicrobial Peptides (AMP) has become a critical component of developing new and novel agents necessary for fighting against new strain of drug-resistant microbes like bacteria and fungi. However, for researchers to be able to experiment with various strains of these AMPs require lots of time and expensive costs to test the validity of each variant - and thus not a scalable in practice.

To reduce the overall search space for the possible AMPs to experiment on, researchers have turned to machine learning and computational model-based approaches for determining if a given sequence of protiens are in fact AMPs or Non-AMPs. Currently, there are various online web-services which allow for researchers to classify whether the given sequences are AMPs. Using these services, they can immensely accelerate their work.

However, one critical concern for these models is the validity of their robustness and integrity with regard to their prediction accuracy. Thus, a careful review of each of these services would need to be evaluated to ensure that the reported results from these papers are in fact correct. Furthermore, upon an observation of a very small samples which were randomly shuffled, we have found that the models have incorrectly misclassified these samples as valid AMPs.

From the basis of this observation, we have curated a synthesized dataset comprised of both real AMP sequences, as well as a collection of randomly shuffled AMP sequences of various k-groups - establishing a dataset to expose non-robust models. Through establishing a proper baseline on this dataset, we will systematically experiment on various online services listed by Gabere et. al to formulate a proper baseline and devise new models which will attempt to out-perform the state-of-the-art models.
