Handwritten Letters to 3D-Printed Braille Letters
This is a team project for my CS370 class that involved the use of a Raspberry Pi to communicate and coordinate two external devices. I acted as the team leader and inititated the project, managed the repository for the project, and coordinated the tasks of each member. The goal of the project was to use a camera to take a picture of some handwritten text, which is then uploaded to the Raspberry Pi. Using Python, we would preprocess the image, and use OpenCV to find and extract contours, leading to individual letters of specific size. The letters would then be sequentially classified by a convolutional neural network trained using the EMNIST dataset on handwriting. After this, the letters are combined using stl models into a single 3D model along the y-direction. We used slic3r to slice the stl file into gcode using the shell and sent that to the Raspberry Pi using ssh and sftp. The pi would then serially send each line of gcode to the printer to be printed.
Data Augmentation Using Generative Adversarial Networks
This was a team project for my CS345 class, where I worked with a teammate to research and use GANs as a way to improve the accuracy of classifiers. We first researched neural networks and the workings of GANs to understand how the model functions. Then, we used TensorFlow as the framework to implement the GAN model to generate data that could be augmented to the test set. We trained the generator on various splits of the original training data and noted how effective the augmentation was. This was compared to the baseline accuracy of just the original data on a SVC classifier to train and test. The use case for this was to improve the data on which to test as a mean of improving the accuracy of the classifier with better data produced by the GAN.
CS345: Machine Learning Foundations and Practice
Introduced machine learning algorithms and tools for predictive modeling presented using case studies that inform their use in real-world applications. Utilized python, numpy, pandas, matplotlib, R, etc. for data analysis and predictions.
