“Generative AI Intelligent Process Automation Platform” project on Leonardo HPC

Uhura Solutions is developing AI platform for document-driven process automation in financial services. The “Generative AI Intelligent Process Automation Platform – GAIPAP” project is a transformative initiative aimed at revolutionizing the financial industry through the integration of advanced AI-driven automation solutions that combine capabilities of Large Language Model (LLM), low-code development, and process automation workflows. This unique fusion of technologies holds the potential to significantly enhance operational efficiency, cost reduction, and customer experience within the financial sector.

An exceptional aspect of the platform is the incorporation of fine-tuned Large language models (LLMs), which sets it apart from generic AI solutions. These LLMs, refined for the financial industry’s unique language, context, and patterns, promise to deliver more precise and relevant insights. The platform’s value proposition is further strengthened by its ability to streamline workflows, offer scalability, real-time data insights, and elevate customer experiences. The integration of a low-code development framework and process automation workflows enables swift prototyping and deployment of AI-driven models, thereby accelerating time-to-market and capitalizing on market opportunities effectively.

The project involves the use of open-source Python libraries and pre-trained Large language models which are fine-tuned on a custom-made private dataset created by the team, allowing for specialized tasks within the financial sector. Leonardo supercomputer enabled us to make a leap with GPU training experiments from 1B to 7B and higher Large language models. We are focusing on various LLM research and optimization methods in this phase of the project, which include hyperparameter tuning, model quantization and pruning, and parameter efficient fine-tuning (PEFT). Special attention is put on dataset preprocessing including quality filtering, deduplication and privacy redacting.

This project, developed and managed by Uhura Solutions, was awarded with 4,500 node hours of GPU resources (8x64GB) on the Leonardo Buster HPC for a duration of 12 months.

Master thesis: HPC/AI for breast cancer detection

Ms. Tamara Pavlovic defended her MSc thesis on the use of HPC/AI for creating prediction models for breast cancer detection on 23.10.2024. With the support from NCC Montenegro, Ms Pavlovic did her research in the context of the HPC4S3ME project and the focus was on AI and computer vision applications in medicine. From the motivational point of view, we congratulate Tamara for finalizing and defending her thesis during the Breast Cancer Awareness Month (‘Pink October’) as people around the world adopt the pink colour and display a pink ribbon to raise awareness about breast health.

ABSTRACT – Artificial Intelligence (AI) is revolutionizing numerous sectors, including medicine, by offering innovative methods for diagnosing, treating, and researching diseases. This master’s thesis focuses on the application of AI in the diagnosis of breast cancer, using computer vision algorithms to analyze mammographic images. Through a combination of convolutional neural networks (CNNs) and deep learning, models have been developed that identify malignant changes, potentially contributing to earlier and more precise disease detection. The thesis examines in detail how AI can improve the efficiency of screening processes, reduce the time required for diagnosis, and enable a more personalized approach to treatment. In addition to technological progress, ethical issues such as patient safety and the transparency of AI systems are also considered. The results of this study confirm that the application of AI in breast cancer diagnostics can significantly enhance medical procedures. The models tested, ResNet152 and DenseNet121, demonstrated quite good performance in classifying breast cancer. Their AUC scores, which exceed the threshold of 0.9, indicate their potential for use in clinical practice. These findings not only contribute to the improvement of diagnostic processes but also open up opportunities for further research and development of AI technologies in medicine.

Master thesis: HPC/AI in precision agriculture

Mr Mato Martinovic defended his MSc thesis on 23 octiber 2024. His research focused on detecting plant deseases for applications in vineyards. He was experimenting with HPC/AI and computer vision. He is one of the latest graduates from the AI master program created under EUROCC project and his mentoring was done with the support of EUROCC NCC Montenegro.

ABSTRACT – This research analyzes the use of computer vision in the field of viticulture. The thesis describes problems in viticulture, computer vision and its use in this field. The paper analyzed the performance of ResNet50, VGG16 and MobileNet models in the classification of diseases and grapevine species. The models achieved accuracy of 98.67%, 97.28%, and 98.72% on the original test data set, while on the extended one, they achieved 87.47%, 72.07%, and 86.64%, respectively, when classifying diseases. In species classification, the models achieved accuracies of 70%, 78% and 88% on the original test data set, and 66%, 51% and 72% on the extended one, respectively. The VGG-16 model had the largest difference in accuracy over extended data, while ResNet had the smallest decrease in accuracy in both cases, which implies that ResNet generalizes the data better. The paper presents the process of creating a platform that allows users to post an image and receive a prediction value through a mobile application.
