18 September 2017
09:00 am

The volume of data is rapidly increasing due to the development of the technology of information and communication. This data comes mostly in the form of streams. Learning from this ever-growing amount of data requires flexible learning models that self-adapt over time. In addition, these models must take into account many constraints: (pseudo) real-time processing, high-velocity, and dynamic multi-form change such as concept drift and novelty. This workshop welcomes novel research about learning from data streams in evolving environments. It will provide the researchers and participants with a forum for exchanging ideas, presenting recent advances and discussing challenges related to data streams processing. It solicits original work, already completed or in progress. Position papers are also considered. This workshop is combined with a tutorial treating the same topic and will be presented in the same day.

The Workshop

ECML/PKDD 2019 Workshop on
IoT Stream for Data Driven Predictive Maintenance

Workshop + Tutorial
16 September 2019
09:00 am

Maintenance is a critical issue in the industrial context for the prevention of high costs or injures.
The emerging technologies of Industry 4.0 empowered data production and exchange which
lead to new concepts and methodologies exploitation for maintenance. Intensive research effort
in data driven Predictive Maintenance (PdM) has been producing encouraged outcomes.
Therefore, the main objective of this workshop is to raise awareness of research trends and
promote interdisciplinary discussion in this field.

Motivation and focus

Maintenance is a crucial topic for industrial machines, medical equipment, energy systems,
passengers transport vehicles and home appliances among others. Cost reduction, machine
reliability, operation, safety and time reduction have been the main concerns of companies and
organizations. Meanwhile, Industry 4.0 brought new opportunities of meaningful data collection
and storage. Promising data-driven methodologies shrive for predictive maintenance becoming
a strong alternative.
This workshop will be centered on questions such as when to perform a maintenance action?
How to estimate components current and future status? How accurate are the existing
methods? Which data should be used? What decisions tools should be developed for
prognostic. How can Data Mining and Machine Learning (Artificial Intelligence in general)
contribute to answer these questions?
Therefore, this event is an opportunity to bridge researchers and engineers to discuss the
emerging topics and the key trends.

The Tutorial

Tutorial: IoT Data Stream Mining in Practice

The challenge of deriving insights from the Internet of Things (IoT) has
been recognized as one of the most exciting and key opportunities for both academia
and industry. The advent of IoT applications is here: industry 4.0, connected indus-
try, industry automation, smart cities, smart grids, energy efficiency, etc. All this IoT
applications require advanced analysis of big data streams from sensors and small
devices, while addressing security and privacy concerns. This tutorial is a gentle
introduction to mining IoT big data streams. The first part introduces data stream
learners for several learning tasks including distributed algorithms. The second and third part
present some applications for predictive maintenance, prediction for renewable ener-
gies, and social network analysis for telecommunications data streams.  The last part presents how to use Apache Spark Streaming for applying scalable machine learning on Big Data streams.

The Tutorial

Tutorial: Predictive maintenance for industrial complex systems: A case-study on predictive
maintenance of solar power plants within the context of energy transition
Slides: Part I, Part II and Part III

Predictive maintenance is a central cornerstone in today’s industrial applications and systems
ranging from on-line manufacturing rails and production lines through (cyber) security problems
to energy fabrication and exploitation facilities. This is because it addresses and develops not
only strategies for the early detection and prediction of machine failures, degraded performance,
undesired situations and occurrences or downtrends in product quality, but also for taking
appropriate actions upon the recognition and prediction of such occasions. Such actions are
indispensable for reducing waste, production costs, customer complaints and thus, in the long
run, also for increasing the income of companies, for guaranteeing higher quality of production
items, software and user frontends and finally for reducing the pollution of the environment. In
the extreme case of severe system failures, any risks of operators working with the system can
be avoided by predictive maintenance. High-qualitative methodologies and functioning
procedures for fully- or at least semi-automated tasks are required to assure efficiency and
economy of predictive maintenance systems. Self-adaptivity of the methods and models is
necessary to handle significant dynamics and non-stationary environments adequately. Recent
developments of proper methodologies to tackle these issues and their application in real-world
predictive maintenance installations will be the content of this tutorial concluded by a discussion
about future challenges and open issues. This subject has many applications with increasing
size such as production systems, energy production, energy distribution, energy management,
renewable energy production (utilities/distributed, offshore/onshore wind farms, solar centers),
cyber security, internet of things etc. A case-study related to the predictive maintenance of
renewable energy resources will be used through the tutorial in order to illustrate the different
notions, concepts, and presented methods.
