Abstract: |
With the
current advances in the Internet of Things (IoT), smart sensors and
Artificial Intelligence (AI), a new generation of condition monitoring
solutions for smart manufacturing is starting to emerge. Computer Numerical
Control (CNC) machines can now be sensorised and the vast amount of data
generated can be processed using Machine Learning (ML) techniques. These can
provide insights about the condition of the machine or tool in real-time,
which can then be used by decision makers. This is fundamental in order to
reach a new level of manufacturing capabilities in the context of Industry
4.0 (Lasi et al, 2014). Most current monitoring solutions rely on the
off-line generation of models before they can be used online. This is not
ideal when the data holds complex evolving features. There is a lack of
approaches that are capable of determining what to learn and when to learn.
This paper presents preliminary results on a new deep learning approach based
on Bayesian Convolutional Neural Networks (BCNN) for online tool condition
classification. Based on the uncertainty of the model, the proposed approach
can determine using an entropy acquisition function if the incoming data
cannot be classified, and therefore needs to be labelled and used for
re-training. This constitutes the first step towards an online active
learning tool condition monitoring approach. We demonstrate using a machine
tool data set that the active learning approach can achieve similar accuracy
of a deterministic Convolutional Neutral Network (CNN) with a smaller
training data set. |
