Chaotic Variational Auto encoder-based Adversarial Machine Learning

no code implementations25 Feb 2023 Pavan Venkata Sainadh Reddy, Yelleti Vivek, Gopi Pranay, Vadlamani Ravi

In this paper, we performed VAE-based adversary sample generation and applied it to various problems related to finance and cybersecurity domain-related problems such as loan default, credit card fraud, and churn modelling, etc., We performed both Evasion and Data-Poison attacks on Logistic Regression (LR) and Decision Tree (DT) models.

Parallel and Streaming Wavelet Neural Networks for Classification and Regression under Apache Spark

no code implementations7 Sep 2022 Eduru Harindra Venkatesh, Yelleti Vivek, Vadlamani Ravi, Orsu Shiva Shankar

After the advent of big data, as data gets generated at a brisk pace, it is imperative to analyze it as soon as it is generated owing to the fact that the nature of the data may change dramatically in short time intervals.

Feature subset selection for Big Data via Chaotic Binary Differential Evolution under Apache Spark

no code implementations8 Feb 2022 Yelleti Vivek, Vadlamani Ravi, P. Radhakrishna

Hence, we embed Logistic and Tent chaotic maps into the BDE and named it as Chaotic Binary Differential Evolution (CBDE).
