SINGPRO project – Combining Data Analytics with Process Optimization

Date: December 02, 2019

Abstract: The aim of the SINGPRO project is to merge the Big Data platforms, machine learning and data analytics methodologies with process planning and scheduling optimization technologies. It applies these technologies to provide online, reactive and anticipative tools for more sustainable and efficient operations. The currently employed classical mathematical optimization models are limited by fixed parameter sets, which are commonly updated off-line and represent only statistical averages. Such parameters could be estimated much more precisely in an on-line fashion using Big Data technologies. By creating such collaboration interfaces between scheduling optimization, big data analytics and machine learning, the process related decision-making will become much more agile, self-aware and flexible. With the sophisticated data analytics methods, one can embed to the overall key performance indicators (KPI) also all information about the process, e.g., tracking abnormal situations (anomaly detection), individual process equipment performance degradations (predictive maintenance), anticipated process timings (prediction of process behavior) and scenario simulation (e.g., artificial intelligence AI planning). This is joint work with Iiro Harjunkoski from Aalto/CHEM.

Machine learning in drone remote sensing

Date: November 18, 2019

Abstract: Utilization of unmanned aerial vehicles, drones, has increased explosively during the past couple of years. Integrating analytics and actuation either utilizing individual drones, drone teams or drone swarms will enable robotization of various environmental operations in the future. This presentation focuses on drone based remote sensing in agricultural and forestry applications. Drones become intelligent when coupled with sensors and analytics. Imaging sensors (color, hyperspectral and multispectral cameras) enable exploration of objects’ 3D structure, and reflection and absorption characteristics. Essential data preprocessing steps are georeferencing, 3D object reconstruction and radiometric calibration. Machine learning plays a fundamental role in building the analytics process. The physical observations measured in field or in laboratory are related to the remote sensing observations and models are built to extract information. Then in analytics applications remote sensing data are fed to the analyzer and the information are extracted utilizing the models. This presentation deals with remote sensing sensor, data calibration and machine learning and presents selected case studies in forest inventory, tree health analysis and grass quality and quantity assessment.

Bio: Dr. Eija Honkavaara is Research Manager at the Finnish Geospatial Research Institute in the National Land Survey (FGI) and Docent at the Aalto University in the field of Automatic Systems in Photogrammetry.

The DroneFinland-team led by Dr Honkavaara has developed several generations of high-performance drone remote sensing systems with cameras, hyperspectral sensors, analytics applications as well as inhouse data processing chains. She has a wide international research network, is a leader of working group “Hyperspectral Imaging Applications” in the International Society for Photogrammetry and Remote Sensing (ISPRS) and has led several national and international projects on UAV remote sensing.

FCAI Simulator-based inference: AI-assisted vaccine development

Date: November 04, 2019

Abstract: Several recent studies suggest that negative frequency-dependent selection (NFDS) acting through accessory genome loci is a strong force influencing the population evolution of major human bacterial pathogens. Such models can be fitted using likelihood- free inference for simulator-based statistical models, for example using the ELFI software (elfi.ai). Here we review some of these results and combine them with machine learning to introduce a practical method for optimizing vaccines by jointly using data from genomic population surveys and epidemiological studies. The results may lead to largely improved workflows to design new vaccines.

Engineering and testing of AI systems

Date: September 30, 2019

Abstract: There is no AI without software. To build and deploy AI systems for real use far more is needed than machine learning models. In this talk, I will briefly describe the software engineering challenges in the development of AI systems. Surprisingly, the intersection of AI and SW engineering has only recently started to attract wider interest. I will, in particular, discuss the testing of AI systems, how it differs from classical SW testing, and what kind of new interesting problems arise. I will conclude with an example of our own work of fault injection to datasets for the testing of ML systems.

Can AI be responsible?

Date: September 23, 2019

Abstract: The question whether AI can be responsible can be understood in two ways: Either as “Can AI agents be responsible?” or “Can AI research be responsible?”. I will argue that only the latter is possible, because AI agents including robots are not autonomous in the sense required by fitness to be held morally responsible. The argument employs Alfred Mele’s history-sensitive account of autonomy and responsibility to the effect that even if robots were to have all the capacities required of moral agency, their history would deprive them from autonomy in a responsibility-undermining way.

The talk is based on joint work with Pekka Mäkelä, in particular the article: Raul Hakli & Pekka Mäkelä: Moral Responsibility of Robots and Hybrid Agents. The Monist, Volume 102, Issue 2, April 2019, Pages 259–275, https://doi.org/10.1093/monist/onz009
