Recent advancements in machine learning methods have allowed companies to develop advanced computer vision aided production lines that take advantage of the raw and labeled data captured by high-definition cameras mounted at vantage points in their factory floor. We experiment with two different methods of developing one such system to automatically track key components on a production line. By tracking the state of these key components using object detection we can accurately determine and report production line metrics like part arrival and start/stop times for key factory processes. We began by collecting and labeling raw image data from the cameras overlooking the factory floor. Using that data we trained two dedicated object detection models. Our training utilized transfer learning to start from a Faster R-CNN ResNet model trained on Microsoft’s COCO dataset. The first model we developed is a binary classifier that detects the state of a single object while the second model is a multiclass classifier that detects the state of two distinct objects on the factory floor. Both models achieved over 95% classification and localization accuracy on our test datasets. Having two additional classes did not affect the classification or localization accuracy of the multiclass model compared to the binary model.
Partnering with a local Great Hearts Academy, we decided to look into why kids tend to not enjoy learning math. Prior to this project, we reflected on our individual experiences with math. One of us found it to be easy and thoroughly enjoyed it throughout school, while the other struggled to understand math and never enjoyed learning the subject. We wanted to look into why that could be. Was it just our teacher? Was it our curriculum? Or was it something deeper? In this project, we explore existing research behind teaching math, as well as interview teachers and students to get their perspective. Our findings showed us that self efficacy and math abilities go hand in hand. We also learned that a growth mindset is essential as students develop problem solving skills. Finally, using our findings, we suggested ways in which teachers and students can make learning math more enjoyable.
In this thesis, I discuss the development of a novel physical design flow introducing standard-cell neurons for ASIC design. Standard-cell neurons are implemented on silicon as a circuit that realizes a threshold function. Each cell contains flash transistors, the threshold voltages of which correspond to the weights of the threshold function. Since the threshold voltages are programmed after fabrication, any sequential logic containing a standard-cell neuron is a logical black box upon delivery to the foundry. Additionally, previous research has shown significant reductions in delay, power, and area with the utilization of these flash transistor (FTL) cells. This paper aims to reinforce this prior research by demonstrating the first automatically synthesized, placed, and routed secure RISC-V core.
The focus of my honors thesis is to find ways to use deep learning in tandem with tools in statistical mechanics to derive new ways to solve problems in biophysics. More specifically, I’ve been interested in finding transition pathways between two known states of a biomolecule. This is because understanding the mechanisms in which proteins fold and ligands bind is crucial to creating new medicines and understanding biological processes. In this thesis, I work with individuals in the Singharoy lab to develop a formulation to utilize reinforcement learning and sampling-based robotics planning to derive low free energy transition pathways between two known states. Our formulation uses Jarzynski’s equality and the stiff-spring approximation to obtain point estimates of energy, and construct an informed path search with atomistic resolution. At the core of this framework, is our first ever attempt we use a policy driven adaptive steered molecular dynamics (SMD) to control our molecular dynamics simulations. We show that both the reinforcement learning (RL) and robotics planning realization of the RL-guided framework can solve for pathways on toy analytical surfaces and alanine dipeptide.
For my Honors Thesis, I decided to create an Artificial Intelligence Project to predict Fantasy NFL Football Points of players and team's defense. I created a Tensorflow Keras AI Regression model and created a Flask API that holds the AI model, and a Django Try-It Page for the user to use the model. These services are hosted on ASU's AWS service. In my Flask API, it actively gathers data from Pro-Football-Reference, then calculates the fantasy points. Let’s say the current year is 2022, then the model analyzes each player and trains on all data from available from 2000 to 2020 data, tests the data on 2021 data, and predicts for 2022 year. The Django Website asks the user to input the current year, then the user clicks the submit button runs the AI model, and the process explained earlier. Next, the user enters the player's name for the point prediction and the website predicts the last 5 rows with 4 being the previous fantasy points and the 5th row being the prediction.
