Solar Forecasting

https://github.com/openclimatefix/nowcasting
A short-term PV energy output forecasting project for the UK's National Grid. I was one of the research engineers who built the satellite data processing application that takes live EUMETSAT RSS imagery every five minutes and transforms it into a Zarr store.

Worked on creating the first public implementations of state-of-the-art Google MetNet, MetNet-2, and DeepMind DGMR models, as well as graph weather models for forecasting the weather and solar power output directly. Additionally, I built our data transformation pipeline, released our training data, and trained models on HuggingFace to enable easier access and research by the community. I worked with open source contributors to ensure the code I wrote was as widely functional as possible and that the performance of the data pipelines and models was as efficient as possible.

FACTNN

https://github.com/jacobbieker/factnn
A Tensorflow-based application for analyzing, classifying, and estimating the original energy of events detected at the First G-APD Cherenkov Telescope (FACT).

This was my dissertation for my bachelor's degree. I built the data pipeline from the original compressed data format into an easier-to-work-with format, created the neural networks, and succeeded in outperforming the current state-of-the-art model for classifying the type of event and determining its original energy using 3D convolutional neural networks (CNNs).

I ended up presenting the research at the American Astronomical Society meeting.

Project Reslience

https://www.itu.int/en/ITU-T/extcoop/ai-data-commons/Pages/project-resilience.aspx
A project run by the UN agency, the International Telecommunication Union (ITU), to help local and regional governments choose the most cost- or CO2-effective actions to reduce their carbon emissions.

I am on the MVP working groups for data and machine learning, where I have been pulling together public datasets and converting them to a standard format for use in later machine learning models.

Diabetic Retinopathy Image Analysis and Stitching

A PyTorch-based project for enabling iPhone videos of eyes to be stitched together and filtered to find diagnosable quality images to send to an ophthalmologist for diagnosis.

I built the training pipeline and took new research models to stitch the video frames into high-quality images. I also productionized the models to fit on more constrained hardware and helped deploy the models to AWS.

Machine Learning for On-board Hyperspectral Image Segmentation for NASA

I designed and built models to segment out clouds for onboard future hyperspectral Earth observation satellites at NASA.

I used TensorFlow to build U-Net-derived models that worked well to segment out clouds in the raw and uncalibrated hyperspectral images, allowing for no preprocessing to be done and a faster processing time.

LOFARNN

https://github.com/jacobbieker/lofarnn
A PyTorch-based master's dissertation to use machine learning to find supermassive black holes and outbursts in a radio map of the northern hemisphere and associate them with optical counterparts.

I built the data ingestion pipeline, analyzed the crowdsourced data to find labeling errors, and developed and trained models that could successfully associate black holes with optical counterparts for cases where other methods failed.
