Meta learning of hyperparameters for parallel and distributed Gradient Boosted Decision Trees on big data

When Kinaxis trains its machine learning models, it does so on two time scales. Every week or so, it looks at around 10 billion sales records and tries to learn the rapidly-changing “parameters” that best describe this data. Every 3-6 months, it updates 10 thousand collections of “hyperparameters” that govern the parameter-learning process. Kinaxis would […]

Towards Reliable Vibration Design of Mass-Timber and Timber-Concrete Floors: Data, Models, and Practical Guidance

The proposed project studies the vibration behaviour of innovative mass timber floor systems, focusing on cross-laminated timber (CLT) floors supported by CLT beams and timber-concrete composite (TCC) floors with notched connections. Using laboratory testing and numerical modelling, the research aims to enhance the understanding of how these floors respond to dynamic loads, including the effects […]

Map Data Analysis for Lawn Service Optimization

This research investigates the fusion of multi-source geospatial data to overcome key scaling limitations in automated property assessment. The primary research problem addresses object occlusion in satellite imagery, where features can obscure ground-level surfaces and prevent accurate area measurement. We propose and evaluate a novel machine learning approach that geometrically fuses satellite imagery with ground-level […]

A Scalable Nitrous Oxide (N2O) Emissions Predictor Utilizing Fuzzy Logic and Impulse Response Measurements

Nitrous oxide (N2O) is a powerful greenhouse gas with a global warming potential 298 times that of CO2, significantly contributing to climate change through agricultural activities, particularly the application of fertilizers. Accurate and scalable prediction of N2O emissions is essential for sustainable agriculture and climate mitigation. Current methods, such as LSTM-DLM neural networks proposed in […]

Novel Vector Potentiators for AAV-mediated Surfactant B Deficiency correction

Surfactant Protein B (SPB) deficiency is a rare genetic disease where surfactant B is not produced in the lung, proper breathing fails and lungs collapse. The disease usually presents early in life, and unless lung transplantation is performed, no other approaches have provided long-term cure. Yet, lung transplantation is not an ideal approach either, as […]

Fast approximate solutions to large and sparse systems of equations via convex optimization

Many effective Convex Optimization techniques face a common bottleneck: the resolution of large, sparse systems of equations. Despite the important advances in the state-of-art at theoretical and algorithm development, a significant challenge persists in the tendency to overlook the commercial viability of these algorithms. Recent strides in computer hardware, driven by advancements in AI and […]
