Predicting the Impact of Batch Refactoring Code Smells on Application Resource Consumption

no code implementations27 Jun 2023 Asif Imran, Tevfik Kosar, Jaroslaw Zola, Muhammed Fatih Bulut

Although automated batch refactoring techniques are known to significantly improve overall software quality and maintainability, their impact on resource utilization is not well studied.

Entropy-Isomap: Manifold Learning for High-dimensional Dynamic Processes

no code implementations19 Feb 2018 Frank Schoeneman, Varun Chandola, Nils Napp, Olga Wodo, Jaroslaw Zola

Scientific and engineering processes deliver massive high-dimensional data sets that are generated as non-linear transformations of an initial state and few process parameters.

Scalable Exact Parent Sets Identification in Bayesian Networks Learning with Apache Spark

1 code implementation18 May 2017 Subhadeep Karan, Jaroslaw Zola

In Machine Learning, the parent set identification problem is to find a set of random variables that best explain selected variable given the data and some predefined scoring function.

Error Metrics for Learning Reliable Manifolds from Streaming Data

no code implementations13 Nov 2016 Frank Schoeneman, Suchismit Mahapatra, Varun Chandola, Nils Napp, Jaroslaw Zola

In this paper, we argue that a stable manifold can be learned using only a fraction of the stream, and the remaining stream can be mapped to the manifold in a significantly less costly manner.
