Paris Machine Learning Meetup #1 Season 7: Neuroscience & AI, Time series, Deep Transfert learning in NLP, Media Campaign, Energy Forecasting

** Nuit Blanche is now on Twitter: @NuitBlog **


A big thank-you to Publicis Sapient for welcoming us to their inspiring office. Presentation slides will be available here. The streaming of the event can also be found here:






Publicis Sapient is a digital transformation partner helping companies and established organizations get to their future, digitally-enabled state, both in the way they work and the way they serve their customers. Within Publicis Sapient, the Data Science Team builds machine learning products in order to support clients in their transformation.

Margot Fournier, Publicis Sapient. Classification of first time visitors
A significant share of visitors on a site do not return, making it crucial to identify levers that can decrease bouncing rate. For a client in the retail sector, we developed several models that are able to predict both the gender and the segment in which unlogged and unknown visitors fit in. This allows to personalize the experience from the first visit and prevent users from bouncing.

Maxence Brochard, Publicis Sapient. Media campaign optimization
Internet users leave multiple traces of micro-conversions (searches, clicks, whishlist...) during their visit on an ecommerce site: these micro-conversions can be weak signals of an act of purchase in the near future. To analyze those signals, we built a solution to detect visitors that are likely to convert and target them in while optimizing media campaigns budgets.




The fields of neuroscience and artificial intelligence (AI) have a long and intertwined history. In more recent times, however, communication and collaboration between the two fields has become less commonplace.In https://bit.ly/2WLsMaQ, the authors argue that better understanding biological brains could play a vital role in building intelligent machines. They survey historical interactions between the AI and neuroscience fields and emphasize current advances in AI that have been inspired by the study of neural computation in humans and other animals. Finally they conclude by highlighting shared themes that may be key for advancing future research in both fields.




The recent M4 forecasting competition (https://www.mcompetitions.unic.ac.cy) has demonstrated that the use of one forecasting method alone is not the most efficient approach in terms of forecasting accuracy. In this talk, I will focus on an energy consumption forecasting use case integrating exogenous data such as weather conditions and open data. In particular, I will present a forecasting time series challenge and the best practices observed on the best submissions and showcase an interesting approach based on a combination of classical statistical forecasting methods and machine learning algorithms, such as gradient boosting, for increased performance. Generalizing the use of these methods can be a major help to address the challenge of electricity demand and production adjustment.

Videos: IMA Computational Imaging Workshop, October 14 - 18, 2019

** Nuit Blanche is now on Twitter: @NuitBlog ** 



Stanley ChanJeff FesslerJustin HaldarUlugbek KamilovSaiprasad RavishankarRebecca WillettBrendt Wohlberg just organized a workshop at IMA on computational imaging. Short story as this blog just passed the 8 million page views. Understanding of Compressed sensing was in large part, at least by looking at the stats:hits on this blog, due to an IMA meeting on the subject and the fact that people could watch the videos afterward. Hoping for this workshop to follow the same path. Given the amount of ML in it, I wonder if it shouldn't have been called TheGreatConvergence meeting:-)


This workshop will serve as a venue for presenting and discussing recent advances and trends in the growing field of computational imaging, where computation is a major component of the imaging system. Research on all aspects of the computational imaging pipeline from data acquisition (including non-traditional sensing methods) to system modeling and optimization to image reconstruction, processing, and analytics will be discussed, with talks addressing theory, algorithms and mathematical techniques, and computational hardware approaches for imaging problems and applications including MRI, tomography, ultrasound, microscopy, optics, computational photography, radar, lidar, astronomical imaging, hybrid imaging modalities, and novel and extreme imaging systems. The expanding role of computational imaging in industrial imaging applications will also be explored.
Given the rapidly growing interest in data-driven, machine learning, and large-scale optimization based methods in computational imaging, the workshop will partly focus on some of the key recent and new theoretical, algorithmic, or hardware (for efficient/optimized computation) developments and challenges in these areas. Several talks will focus on analyzing, incorporating, or learning various models including sparse and low-rank models, kernel and nonlinear models, plug-and-play models, graphical, manifold, tensor, and deep convolutional or filterbank models in computational imaging problems. Research and discussion of methods and theory for new sensing techniques including data-driven sensing, task-driven imaging optimization, and online/real-time imaging optimization will be encouraged. Discussion sessions during the workshop will explore the theoretical and practical impact of various presented methods and brainstorm the main challenges and open problems.
The workshop aims to encourage close interactions between mathematical and applied computational imaging researchers and practitioners, and bring together experts in academia and industry working in computational imaging theory and applications, with focus on data and system modeling, signal processing, machine learning, inverse problems, compressed sensing, data acquisition, image analysis, optimization, neuroscience, computation-driven hardware design, and related areas, and facilitate substantive and cross-disciplinary interactions on cutting-edge computational imaging methods and systems.
