Abstract
Generative adversarial network (GAN) has been regarded as a promising solution to many machine learning problems, and it comprises of a generator and discriminator, determining patterns and anomalies in the input data. However, GANs have several common failure modes. Typically, a mode collapse occurs when a GAN fails to fit the set optimizations and leads to several instabilities in the generative model, diminishing the capability to generate new content regardless of the dataset. In this paper, we study conditional limiter solutions for mode collapse for the Intrusion Detection System (IDS) Control Flow GAN (ICF-GAN) model. Specifically, the ICF-GAN’s mode collapse instances are limited by a mini-batch method that significantly improves the model accuracy. Performance evaluation is conducted using numerical results obtained from experiments.
Highlights
Generative adversarial networks (GAN) are unsupervised learning models, which comprise of a generator and discriminator, determining patterns and anomalies in the input data [1]
The problem of mode collapse can be explained in terms of gradient exploding where there is imbalance or inconsistency exists between generator and discriminator
We proposed to enhance the GAN-enabled ingestion process for PCAPbased malware detection (i.e., Intrusion Detection System) similar to the proactive analysis Causal Analysis based on System Theory (CAST) model [4,5]
Summary
Generative adversarial networks (GAN) are unsupervised learning models, which comprise of a generator and discriminator, determining patterns and anomalies in the input data [1]. Alternative methods address mode collapse issues with varieties of proposed GAN architectures, including Wasserstein GAN (WGAN) [11], unrolled GAN [12,13], AdaGAN [14], VEEGAN [15], zero-entered gradient penalty on training examples (GAN0GP) [16], zero-entered gradient penalty on interpolated samples (GAN-0GP) [17] and nudged-Adam (NuGAN) [18]. These architectures have been computed on different distributions of data as well as both synthetic and real datasets.
