Automatic Geo-alignment of Artwork in Children's Story Books

A study was conducted to prove AI software could be used to translate and generate illustrations without any human intervention. This was done with the purpose of showing and distributing it to the external customer, Pratham Books. The project aligns with the company's vision by leveraging the generalisation and scalability of Machine Learning algorithms, offering significant cost efficiency increases to a wide range of literary audiences in varied geographical locations. A comparative study methodology was utilised to determine the best performant method out of the 3 devised, Prompt Augmentation using Keywords, CLIP Embedding Mask, and Cross Attention Control with Editorial Prompts. A thorough evaluation process was completed using both quantitative and qualitative measures. Each method had its own strengths and weaknesses, but through the evaluation, method 1 was found to have the best yielding results. Promising future advancements may be made to further increase image quality by incorporating Large Language Models and personalised stylistic models. The presented approach can also be adapted to Video and 3D sculpture generation for novel illustrations in digital webbooks.

Machine Learning based prediction of Glucose Levels in Type 1 Diabetes Patients with the use of Continuous Glucose Monitoring Data

A task of vital clinical importance, within Diabetes management, is the prevention of hypo/hyperglycemic events. Increasingly adopted Continuous Glucose Monitoring (CGM) devices offer detailed, non-intrusive and real time insights into a patient's blood glucose concentrations. Leveraging advanced Machine Learning (ML) Models as methods of prediction of future glucose levels, gives rise to substantial quality of life improvements, as well as providing a vital tool for monitoring diabetes. A regression based prediction approach is implemented recursively, with a series of Machine Learning Models: Linear Regression, Hidden Markov Model, Long-Short Term Memory Network. By exploiting a patient's past 11 hours of blood glucose (BG) concentration measurements, a prediction of the 60 minutes is made. Results will be assessed using performance metrics including: Root Mean Squared Error (RMSE), normalised energy of the second-order differences (ESOD) and F1 score. Research of past and current approaches, as well as available dataset, led to the establishment of an optimal training methodology for the CITY dataset, which may be leveraged by future model development. Performance was aligned with similar state-of-art ML models, with LSTM having RMSE of 28.55, however no significant advantage was observed over classical Auto-regressive AR models. Compelling insights into LSTM prediction behaviour could increase public and legislative trust and understanding, progressing the certification of ML models in Artificial Pancreas Systems (APS).
