The malware detection arms race involves constant change: mal-ware changes to evade detection and labels change as detection mechanisms react. Recognizing that malware changes over time, prior work has enforced temporally consistent samples by requiring that training binaries predate evaluation binaries. We present temporally consistent labels, requiring(More)
We present and evaluate a large-scale malware detection system integrating machine learning with expert reviewers, treating reviewers as a limited labeling resource. We demonstrate that even in small numbers, reviewers can vastly improve the system's ability to keep pace with evolving threats. We conduct our evaluation on a sample of VirusTotal submissions(More)
Cloud computing has become increasingly popular. Many options of cloud deployments are available. Testing cloud performance would enable us to choose a cloud deployment based on the requirements. In this paper, we present an innovative process, implemented in software, to allow us to assess the quality of the cloud performance data. The process combines(More)

Abstract—Explosive growth in the number of passwords for web based applications and encryption keys for outsourced data storage well exceeds the management limit of users. Therefore outsourcing keys(More)

Our project examines the implicit interactions of the corporate ecosystem constructed with data gathered from stock prices across the last decade. The correlation of stock price residuals is used to construct a corporate information network. We found that residual of stock price among each company's tradable security in the S&P 500 followed a roughly normal(More)
NIRS is a non-invasive spectroscopic method for measuring oxygenated and deoxygenated hemoglobin concentrations in cortical regions of the brain. In this report we investigate the use of machine learning techniques to train a model for online classification of a specific motor activ ity-finger tapping-using NIRS data. Thus, NIRS measurements of blood flow(More)
