Location: Clamart, France

Come and Join SLB’s AI Lab in Paris. We are currently offering internship to bright minds specialized in Data Science and Artificial Intelligence. Discover a multinational company. We have brought a little bit of the Silicon Valley in Paris. Experience working within a team of young and fun passionate Data Scientists, tackling real business challenges, in tandem with business experts who are sitting at your desk.

The Artificial Intelligence & Machine Learning Data Scientist helps develop software and processes that can be used for robotics, artificial intelligence programs and application. In close collaboration with the business and métiers, the data scientist offers mathematical and statistical models from the collected data to augment, improve or speed up human decisions within the Energy sector. With SLB you will be given the opportunity to apply your expertise and deploy deep learning solutions at scale on real-world problems, supporting many areas of SLB’s business. SLB is the first Energy service company to move its processes and workflows in the cloud. This gives the Embedded AI Lab the perfect opportunities to leverage these innovative technologies and resources. As part of the Embedded AI Lab you will be able to test, experiment and research with the bleeding edge environment with Petabits and Petabits of data. You will be in charge of applying research and delivery of Proof of Concepts solutions, responding to a clear and specific business needs.

Description:

Two of the biggest issues preventing the widespread use of machine learning in the Energy industry is the need for expert labelled data, and the lack of confidence in the trained models. The issue with expert labelled data is that the experts generally only have a very limited amount of time available for such labelling. This means that any project must limit itself to the very minimum number of labels necessary. The issue with confidence in the trained models on the other hand, is the lack of knowledge of when the model can be trusted or not. Given data similar to the training data the model might indeed perform very well, while it can fail catastrophically when the data becomes sufficiently different from the training data. Is there a way for the model itself to predict such failures, and tell us when and when not it should be trusted?

These two seemingly disjointed topics are brought together in the field of “Active Learning”. Its goal is to reduce the number of labels necessary by selecting data points to be labelled, by predicting how much a label on a given datapoint would improve the model’s performance on all unseen data. This way it aims to minimize the cost of obtaining labeled data, in order to get a model to a given performance level. To do this a key piece of information is how certain the model is of the label of any unseen data point. If the model already knows the answer, having it labeled will add nothing to its performance.

This internship aims at investigating the topic of active learning in SLB, and help us develop recommendations and best practices. We are interested in analyzing uncertainty sampling query strategies, based on selecting instances for which the model is the least certain how to label. In order to do this, a trustworthy representation of uncertainty is necessary and should be considered as a key feature of any machine learning method. A particular focus during this internship will be devoted to analyzing the types of uncertainty in prediction models, their sources, and an accurate estimation of overall prediction uncertainty.

The objective of this internship is to analyze state-of-the-art methods for uncertainty estimation and active learning, and then apply it in real Energy applications. The intern will have the opportunity to do high-level theoretical and applied research in this field, contribute to new product developments as well as working with project experts and data scientists from the AI Lab located on Clamart Campus.

The intern will be in charge of defining the best strategy and methodology to provide a new answer product based on data science technologies (statistics and machine learning algorithms). The intern will have the opportunity to use available experimental equipment and numerical tools (large possibilities within SLB with research and engineering centers.
