ChatGPT as a combined OCR and key-value extractor – Nemi Pelgrom, Industry PhD student at Fortnox

This study presents the results of an experiment of using the AI chatbot chatGPT as a combined OCR and key-value extractor. The dataset used consisted of 1000 real invoices and 500 images of real receipts from a wide variety of Swedish market sectors. This tool demonstrated an accuracy rate of 99.8% in extracting key financial data from invoices, and 100% accuracy from images of receipts, showcasing its potential as a one-stop solution for financial document processing.

Data-Driven Approach Towards Objective Evaluation of the Gravel Road Condition – Keegan Mbiyana, PhD-student in Mechanical Engineering

Visual windshield surveys are the primary method for assessing the condition of gravel roads, but they can be prone to human judgment errors and can be time-consuming. There is a need to shift to an objective assessment of the condition of gravel roads by leveraging advances in sensor technology and data processing techniques for efficiency and effectiveness. This seminar will present work conducted in the Department of Mechanical Engineering in objectively assessing the gravel road condition to improve maintenance planning and decision-making. The results from the field experiments on three gravel roads with different condition classes and the vehicle vibration response collected using Integrated Electronics Piezo-Electric (IEPE) and smartphone accelerometers to verify a proposed rule-based approach will be presented. The challenge of regular monitoring is discussed, considering the remote location of gravel roads. Regular condition monitoring and data collection would require collecting and storing huge amounts of data. Therefore, as part of future work, the seminar will briefly introduce an adaptive sampling technique to reduce redundant or unnecessary data before storage.

Invitation to a new PhD course in Innovation and entrepreneurship at BTH

2024-03-20

Our friends at BTH invites our PhD-student to join their new course offered by the innovation office in Innovation and entrepreneurship during 2024. The course aims to support researchers in the process of taking research results to Innovation, impact and commercialization.

Research impact is no longer solely evaluated on academic publications and teaching programmes. The research funding landscape today expects a clear strategy regarding impact on society included in project proposals. Non-academic research dissemination, either through a start-up company or collaborations with established companies is therefore increasingly important.

The course is divided into three optional modules, i.e., you can register to one or several modules according to your interest (one credit per module). See attached course description for further information.

  • The course starts at 2/4 with an introductory lecture
  • The course is provided by Innovation office at BTH in cooperation with external expert representatives who will give lectures and seminars.
  • Course registration is done by sending email to marie.netz@bth.se at the latest 28th of March.

Abstract

Bridging temporal gaps in vegetation indices satellite data and forecasting the futureTibo Bruneel, PhD student at Softwerk AB
In this research seminar I will present the machine learning work I have done so far in my PhD studies with some intermediate results. The research addresses the challenge of inconsistent temporal data gaps in Sentinel-2 vegetation indices time series and the forecasting of the vegetation index future.

Temporal data gaps occur in sentinel-2 optical data, mostly arising from factors such as cloud cover and adverse weather conditions. Having very inconsistent time series prevents further analysis such as detection, quality control and forecasting. Therefore we first address the data continuity challenge to obtain a consistent daily estimation of the vegetation index.

Given a consistent timeline of daily estimates, we further attempt to predict the near future of the vegetation index. Here we attempt to achieve both a high forecasting accuracy, and a strong generalisability over different locations in the world, as models trained on a single location often are hard to generalise on different environments.
