Academy of Finland funded projects

This project aims at developing theoretical foundations for in-network data management to exploit different types of network resources, enhance the performance of the distributed machine learning models and corresponding applications. Distributed machine learning leverages resources at the network edge, near the data sources, for model training and inference, thereby offloading from these tasks the centralized cloud platforms and satisfying demands of applications for low latency, scalability and privacy. Training ML models at realistic 5GIoT network scales requires processing enormous volumes of data generated by the end-user devices, thus leading to huge amount of data communications between network users and the central cloud platform. As a consequence, the data uploading and training procedure in real-time applications (e.g., ARVR) causes significant performance degradation. Finally, since the training data are collected by network users, preserving the privacy of network users with affordable accuracy loss is an important issue in distributed ML. Developing data aware resource allocation algorithms in distributed ML systems is a complex and open problem. Existing works on distributed ML can be classified into two categories: (i) one focusing on how to run the ML tasks (model training and inference) at the edge devices in a collaborative and resource-optimized manner, and (ii) another focusing on how to exploit ML to find a better solution to the optimization problems in the edge network. It has been illustrated that data quality is a critical factor in machine learning algorithms, and data importance-aware network resource allocation and training algorithms can improve ML systems performance. Therefore, a unified treatment of data selection, communication and computing is required to improve the performance of distributed ML systems. More importantly, protecting against data leakage in the distributed resource-sharing process is an unresolved practical issue in protocol realization.

The Industrial Distributed Edge Architecture over Machine Intelligence for Local Learning (IDEA-MILL) research project addresses the key challenges in future hyper-connected industrial systems to deliver innovative solutions, which are prepared to handle the extremely large data volumes collected from multiple heterogeneous sources, make adequate inference, and provide timely response. Our proposed distributed edge architecture diffuses machine intelligence across the network by bringing more critical and demanding applications closer to smart machines while moving lightweight data and local learning outcomes to the cloud for enterprise-level analytics. Our expected key scientific results are in developing efficient, flexible, and scalable methods that automate model training processes as well as control storage, computing, networking, and radio resources to minimize the associated costs and latencies.

Business Finland funded projects

The ubiquitous presence of Information Technology is making everyday life safer and navigation more convenient. Big corporations are seeing opportunities using data driven people flow analytics to forecast demand and grow their business. KONE identifies people flow as the way people move in and between buildings. Advanced People Flow Solutions combine access and destination control, communication and equipment monitoring to deliver a seamless user experience. HITACHI is producing technologies for people flow analysis to facilitate pedestrian flow and optimize use of public spaces, to add value in the form of more vibrant and more attractive cities.  

People flow business concerns a cost evaluation of overall space capacity and usage patterns using real-time people counting data and calculating the flow rates. People counting is applied to specific areas such as university meeting rooms, government offices, airport lounges, etc., which allow for understanding the workplaces to better allocate resources, avoid unnecessary energy waste and optimize space utilization. People counting can be scaled to city level and provide information on how buildings and services affect people flow volumes and number if they want to charge tourists. For the business sector, occupancy rates and people flow analytics allow for data-driven decisions, optimized operations, elimination of choke points, and improved profitability. For the public sector, transparent people flow data is valuable for policy making and brings about innovation opportunities for officials, businesses, and the people living in the city.

People flow monitorization is attained by selling IT technologies including ELISA’s computer vision4, connected cameras, geolocation WIFI analytics, LoRaWAN, and AGM FLOW LiDAR. These IT devices and cloud services create a new range of business logic (people flow management, asset management, people counting, and traffic flow analysis, and footfall data) making people flow monitoring a realistic investment proposition.  However, higher monetary profit will be accrued by improving machine learning algorithms that gather people flow data without breaching personal privacy. Providing algorithms that configure IoT systems to measure and track specific zones at specific times to get the most appropriate information for the business model. Introducing algorithms that integrate people flow data with digital twins and other systems to optimize the general living environment for humans and robots. Enhancing user recommendation algorithms for way-finding mobile applications and forecasting occupancy, queues, and safety issues in real time.  

The market demand for Untangling people flow products and solutions are driven by every day factors:  rapid urban population growth (8 billion people) leading to constant construction and revitalization of the built environment; large-scale people movement between cities (six million people flying per day); increase of smart cities  (140 cities and growing);  uptake of remote working (at least 22% of the work force),  and increase active aging population calling for safer navigation (1.5 billion people by 2050).  

The purpose of the KONE Untangling People Flow consortium is to create a competence base enabling Finnish companies to grow their business base by increasing their international exports. To develop new technical skills turning IoT technologies and AI informatics into a compelling business logic measured by KPIs. During the project, the consortium partners will meet 9 times and jointly converge their people flow solutions into a single technology two busy test beds: University of Helsinki Kumpula campus (7000 visitors); and Finavia Helsinki-Vantaa airport (11 million passengers a year). The resultant technology will be showcased at FONTYs University, Netherlands (51,000 visitors) and Istanbul airport (64 million passengers per year).  

One of the key use cases of 6G networks will be massive twinning, which is an extension of the digital twin concept of industrial processes introduced in 5G to different type of physical objects. In this perspective, a system based on the use of a digital twin for optimized sensing and communication in Personal Area Networks (PANs) is currently an under researched and not commercialized area. This project aims to start filling the gap in this respect.

The idea of Personal Area Network (PAN) has largely evolved in recent years as result of the increasing number of smart devices that can be interconnected within an individual person’s space, as well as from the multiple type of connectivity technologies that can be used to connect the devices (i.e., short range and long range). Wearable devices such as smartwatches, smart-bands (activity trackers), smart-glasses, and smart portable sensors (e.g., air quality sensors) represent only a limited subset of new devices that can operate within a PANs, along with more conventional computing platforms such as personal computers, smartphones, and tablets. Typically, the set of these devices simultaneously execute multiple applications, which are in turn developed by separate providers, operating according to custom-made APIs and recommended set-up (e.g., type of connectivity to be used, frequency of the sensor data readings, etc.). The entire PAN generates a large amount of data that is typically processed through dedicated services hosted in cloud environments in a multi-tenancy fashion.

Challenges. The data generated by each application running in the cluster of PAN devices is uploaded to the different back-end applications hosted in cloud facilities in a non-orchestrated way. The lack of such orchestration mechanisms, together with the software heterogeneity and the inconsistent setup of the applications executed in each device, can generate various inefficiencies from the perspective of: (Challenge I) overall energy efficiency of the PAN, (Challenge II) poorer sensing data quality due to data redundancy and data inconsistency, and (Challenge III) inefficient offloading and data upload scheduling policies.

Project Goal. Considering the set of challenges and requirements described above, we have identified two key areas that will be driving the R&D activities of our project. The first relates to the development of a smart application "SmartSense Mesh", which can be interoperably installed and executed in a wide set of smart devices belonging to a PAN, for performing actionable data-driven insights aimed to ensure optimized sensing and communication. The second is linked to the development of an innovative digital twin framework "SmartSense Mesh-DT", which can assess—using AI-powered analytics—the adequacy and efficiency of a corresponding physical PAN system.
