Autonomous Driving Software

November 2023 - Present | CPP AIoT Research Lab


alex alex alex alex alex

Working with the Cal Poly Pomona AI research lab as a project lead, I oversaw the development of autonomous driving software, built for lane detection purposes. My team and I constructed a convolutional neural network yielding results with a 93% overall accuracy in test cases. Our model was capable of avoiding obstacles and keeping our remote test car within designated lane markers consistently for 300+ laps, completely free of user input.

Scratch Built Search Engine

Spring 2024 | CS4250 Web Search & Recommender Systems


alex alex alex alex alex

Hand built Recommendation System built utilizing beautifulSoup library, pymongo database functionality and NLTK tokenization & stemming functions. The final product is a search engine capable of locating, crawling, and parsing the CPP college of Civil Engineering Faculty page, storing found information in a MONGODB database, querying said database and performing TF-IDF / Cosine Similarity Calculations to produce a ranked list for results.

Mini Social Media App

Winter 2023 | CS3560 Object Oriented Programming


alex alex alex alex alex

This is an implementation of a very rudimentary social media platform supporting "following", "posting", "liking", and auto updating feed. The User Interface has an admin view, as well as a user view. The User View allows for multiple user's to have views open at once, and if any action is taken, all user view's update automatically. This project implements Object Oriented Programming techniques such as Polymorphism, inheritance and abstraction.

Emotion Detection Neural Network

Fall 2023 | CS4210 Machine Learning and its Applications


alex alex alex alex alex

Utilizing a convolutional neural network, this program is capable of receiving a picture of a human, and predicting with 75% accuracy what emotion is being portrayed in said image. The machine learning model is trained with a set of 20,000 images for 100 epoch's at a learning rate of .01. By the end of training, the test accuracy peaks at a 76%. This model came in third place in a university organized online machine learning competition.

Numerical Method Implementations

Summer 2023 | CS3010 Numerical Methods


alex alex alex alex alex

Terminal based application designed to provide basic functionality for numerical methods such as Bisection, False Position, Newton-Raphson and Secant. The main program runs off of a driver that provides terminal user input to solve equations using the methods mentioned above. If no solution is found, the program has an upper limit, preventing any infinite loops from causing issues. This program is also capable of storing error values as it traverses to find a solution.
