Speech Title: Adaptive Compression of Deep Neural Networks
Abstract:Model compression is crucial for accelerating deep neural networks while maintaining high prediction accuracy. In this talk, I will present a lightweight compression method termed Adaptive SensiTivity-basEd pRuning (ASTER) which dynamically adjusts the filter pruning threshold
concurrently with the training process. This is accomplished by computing the sensitivity of the loss to the threshold on the fly (without re-training),
as carried with minimal overhead on the Batch Normalization (BN) layers. ASTER then proceeds to adapt the threshold so as to maintain a fine
balance between pruning ratio and model accuracy. Extensive experiments on numerous neural networks and benchmark datasets illustrate a state-of-the art trade-off between FLOPs reduction and accuracy, along with formidable computational savings.

Speech Title: Advances and challenges for the automatic discovery of interesting patterns in data
Abstract:Intelligent systems and tools can play an important role in various domains such as for factory automation, e-business, and
manufacturing. To build intelligent systems and tools, high-quality data is generally required. Moreover, these systems need to process complex
data and can yield large amounts of data such usage logs, images, videos, and data collected from industrial sensors. Managing the data to gain insights and improve these systems is thus a key challenge. It is also desirable to be able to extract information or models from data that are easily
understandable by humans. Based on these objectives, this talk will discuss the use of data mining algorithms for discovering interesting and useful patterns in data generated from intelligent systems and other applications.
The talk will first briefly review early study on designing algorithms for
identifying frequent patterns. Then, an overview of recent challenges and advances will be presented to identify other types of interesting patterns in more complex data. Topics that will be discussed include high utility patterns, locally interesting patterns, and periodic patterns. Lastly, the SPMF
open-source software will be mentioned and opportunities related to the combination of pattern mining algorithms with traditional artificial
intelligence techniques for intelligent systems will be discussed.
Biography:Philippe Fournier-Viger (Ph.D) is a Canadian researcher, distinguished professor at Shenzhen University (China). Five years after
completing his Ph.D., he came to China in 2015 and became full professor after receiving a talent title from the National Science Foundation of
China. He has published more than 375 research papers related to data mining algorithms for complex data (sequences, graphs), intelligent
systems and applications, which have received more than 11,000 citations. He is the founder of the popular SPMF data mining library, offering more than 250 algorithms to find patterns in data, cited in more than 1,000 research papers. He is former associate edito-in-chief of the Applied
Intelligence journal and has been keynote speaker for over 15 international conferences and co-edited four books for Springer. He is a co-founder of the UDML, PMDB and MLiSE series of workshops held at the ICDM, PKDD, DASFAA and KDD conferences. <Personal Webpage>
