This paper describes different E-Senses systems, such as Electronic Nose, Electronic Tongue, and Electronic Eyes, which were used to build several machine learning models and assess their performance in classifying a variety of Colombian herbal tea brands such as Albahaca, Frutos Verdes, Jaibel, Toronjil, and Toute. To do this, a set of Colombian herbal tea samples were previously acquired from the instruments and processed through multivariate data analysis techniques (principal component analysis and linear discriminant analysis) to feed the support vector machine, K-nearest neighbors, decision trees, naive Bayes, and random forests algorithms. The results of the E-Senses were validated using …

[Summary] There have been a number of advancements in the detection of personal identifiable information (PII) and scrubbing libraries to aid developers and researchers in their detection and anonymization efforts. With the recent shift in data handling procedures and global policy implementations regarding identifying information, it is becoming more important for data consumers to be aware of what data needs to be scrubbed, why it’s being scrubbed, and to have the means to perform said scrubbing. PII-Codex is a collection of extended theoretical, conceptual, and policy works in PII categorization and severity assessment (Milne et al., 2016; Schwartz & Solove, …

Adversarial Training Of Deep Neural Networks, Anabetsy Termini
CCE Theses and Dissertations
Deep neural networks used for image classification are highly susceptible to adversarial attacks. The de facto method to increase adversarial robustness is to train neural networks with a mixture of adversarial images and unperturbed images. However, this method leads to robust overfitting, where the network primarily learns to recognize one specific type of attack used to generate the images while remaining vulnerable to others after training. In this dissertation, we performed a rigorous study to understand whether combinations of state of the art data augmentation methods with Stochastic Weight Averaging improve adversarial robustness and diminish adversarial overfitting across a wide …
