3-Year PhD position at IRSTEA:

3-Year PhD position in Saint-Etienne:

Probabilistic study of instantiated gaussian processes and application to spatio-temporal data.

Starting date: September or October 2017 Application deadline date: April 14th 2017

Decision announcement date: June 1st 2015

Context

The thesis will take place in the Saint-Etienne part of Camille Jordan Institute. The research will be undertaken in the context of an interdisciplinary project involving also Hubert Curien Laboratory from the University Jean Monnet of St Etienne.

The consortium has scientific expertise on probability and statistics, information and image processing, and machine learning, providing a stimulating scientific environment for this thesis. Last but not least, St Etienne is a very pleasant place to study and work. St Etienne is rated each year as one of the best place in France for studying.

PhD thesis subject

Gaussian processes are non-linear models of continuous random processes which are widely used to describe numerical data as sounds, images, videos, etc. (see for e.g. [W08,Z16]).

A Gaussian process is defined mainly by its expectation function and its covariance function (the kernel).

The description of the kernel using parametric functions and the estimation of these parameters form the focus of many recent works [L05,D16].

In the context of image sequences (knowing that our study is intended to address other types of data), the main objective is no longer to describe a Gaussian process but a set of Gaussian processes that can possess instances (Different temporal or spatial supports), with the aim to analyse videos with dynamic textures (lights, waves, clouds, fields of wheat …) taken from different angles for example.

The main objective of the thesis is to provide a precise mathematical framework for these instanciated Gaussian processes in order to be able to estimate the different parameters (instances, mathematical expectations and kernels' parameters).

First, the PhD student will be intended to make a state-of-the-art about the different kernels and their properties, mainly their stationarity in time and space in order to propose new kernels. The next step is to develop robust parameter estimation methods and to work on the automatic selection of the kernels. Then, the formalism of non-stationary and instanciated Gaussian processes will be developed, together with their numerical simulations. The last step concerns the mixture of instanciated Gaussian processes and their application to real data like videos.

Candidate

We are looking for a motivated student holding a Master degree (on the 1st of September 2015) in the field of applied mathematics (probability, data analysis, estimation and optimization, …) or “computer science” (or “computer vision”) with strong skills in applied mathematics. A good background in software development (algorithmic, Matlab/Octave/Scilab or Python, …) is expected. Knowledges in image processing and machine learning would also be appreciated.

Salary

Net salary: around 1400 euros without teaching activities and around 1650 euros with teaching activities (64 hours per year).

Application process

Your application should include the following documents: - Letter of intent - Grades and ranking during Master 1 and Master 2 - Scientific CV - List of publications (if it exists of course) - Names of Referees (at least 2)

We aim to develop the next generation of statistical inference methods to analyze Earth Observation (EO) data. Machine learning models have helped to monitor land, oceans, and atmosphere through the analysis and estimation of climate and biophysical parameters. Current approaches, however, cannot deal efficiently with the particular characteristics of remote sensing data. We will develop advanced regression (retrieval, model inversion) methods to improve efficiency, prediction accuracy and uncertainties, encode physical knowledge about the problem, attain self-explanatory models, learn graphical causal models to explain the complex interactions between essential climate variables and observations, and discover hidden essential drivers and confounding factors in Climate/Geo Sciences.

Highly motivated researchers with a degree in computer science, statistics, machine learning, electrical engineering, physics, or mathematics are encouraged to apply. All candidates should have a solid understanding and knowledge of machine learning and statistics, and being particularly interested in remote sensing and geoscience problems. The thesis will address problems in regression, graphical models and causal inference. Good programming skills (Matlab/Python/R/C++), a critical and organized sense for data analysis, as well as maturity and commitment, strong communication, presentation and writing skills are a big plus.

It is estimated that by 2050 70% of more food needs to be produced worldwide. It is therefore not only essential to use our resources as efficiently as possible, but also to assess and mitigate the risk to crops. Farming is increasingly driven by machines and with less staff it is difficult for farmers to monitor their crop. There is the drive to use airborne technologies as well as satellite imagery to do this remotely and automate this. The project aims to build up an extensible, probabilistic framework to do this resulting in a database and data model.

The ultimate aim is to not just have a database of the spectral signatures of different plant species, but also to incorporate phenology and health status of the plants. With regards to crops this will help mitigate the risks of droughts and diseases. Irrigation can be directed where needed and fertilizer used more effectively. Early intervention can stop diseases spreading and there will be less use of pesticides and fungicides. Being able to choose an optimal time to harvest will lead to less food wastage.

Using sophisticated machine learning techniques, sparse models of the land cover can be created. These models will help where there is limited up and downlink bandwidth as there are with airborne technologies as well as with satellites. The device gathering the data can carry a sparse model and only where new data is significantly different to the model action is necessary. In the first instance this action will be an alert to an anomaly. Further analysis is then necessary whether the anomaly is expected due to e.g. change of the season, or the anomaly needs intervention or the model needs updating (e.g. a change of crop).

The aim of this PhD project is a probabilistic model of spectral signatures of plants incorporating phenology and diseases. To this end various machine learning techniques will be employed and benchmarked against each other. Data from the CropScape database (https://nassgeodata.gmu.edu/CropScape/) will be combined with data from Avaris (http://aviris.jpl.nasa.gov/alt_locator/) for initial analysis. This can then be enriched with data from the Sentinel satellites for temporal analysis, since the revisit times are shorter. Different resolutions and number of spectral bands need to be given consideration. The techniques will also be assessed on their ability to generate knowledge automatically, for example in which way the spectral signature of a plant changes under increasing drought conditions and whether there are underlying general principles. Another aspect is the development of a confidence measure identifying and quantifying classification error.

The successful candidate will be working closely with David Coomes (Cambridge), Anita Faul (Cambridge), Alistair Forbes (NPL), and Carola-Bibiane Schönlieb (Cambridge).

Applicants should have a masters degree in mathematics or a closely related subject, e.g. an engineering degree with a strong mathematical foundation, and should be UK or EU nationals.

The funds for this studentship are available for 3 years in the first instance.

In order to be considered for this studentship please submit a formal application to the PhD in Applied Mathematics and Theoretical Physics, University of Cambridge via the University's Graduate Admissions website (for more information on this please visit http://www.graduate.study.cam.ac.uk/how-do-i-apply); and send an expression of interest email to grad-administrator@maths.cam.ac.uk which explains why you are interested in this studentship.

PHD Proposal

Title: Accelerating kinetic model construction and better process control by extracting information from transient data

Place: IFPEN, Rond point de l’échangeur, BP 3 - 69360 Solaize - France

PhD position at IFP Energies nouvelles (IFPEN)

The production of ultra-low sulfur diesel is a major challenge for economic and societal perspective. The hydrocracking process is dedicated to maximize the production of such pools. The use of kinetic models is mandatory in order to design and control such processes. These models must be recalibrated for each catalyst generation. This requires the use of long pilot plant tests (several months) and expensive (several hundred k€). The relatively long duration of the tests (1.5 to 2 months) is partly due to the catalyst stabilization at each operating conditions modification (several days) and secondly to the supervision of the test in order to reach targets (conversion efficiency). The objective of this thesis is multiple:

1. Optimize the operating conditions to maximize the information (design of experiments) and use the points in transient mode (points currently acquired to check the stability but not used) for kinetic models fitting

2. Optimize the supervision of pilot plants to reach quickly some targets (conversion, yields)

This will be carried out with following program:

1. Study experimental data in order to provide a catalyst stabilization mechanism

2. Numerical study in order to build the model, test and develop methods for on line identification and develop methods for design of experiments

3. Validation with experimental data

Desired Skills and Experience:

  • Degree in Process System Engineering, Data Mining/Data Science or Computer Science
  • Experience with one or more of the following: Programming skills, Process Engineering, Process Control
  • English skills
  • Motivation to work in a transdisciplinary team

Supervisors: Dr. Benoit Celse, Benoit.celse@ifpen.fr ; Dr. D. Guillaume, denis.guillaume@ifp.fr; Pr. J. Thybaut, Joris.Thybaut@UGent.be

Interested candidates are requested to send a detailed CV, one recommendation letter and university/master transcripts to Benoit Celse at benoit.celse@ifpen.fr.

Self-Organized Representations of Dynamical Environments for a Welcoming Task by an Autonomous Robot



Post-doc position in machine learning in Grenoble, France

Title: Learning welding prediction and classification models from various, heterogeneous sources Duration: 2 years Partners: LIG UGA, LJK UGA, Total Starting date: January 2017 (if possible)

Description: Machine learning methods are meeting an increasing success in various domains, such as marketing with customer behavior prediction, health with patient diagnosis and industry with the optimization of industrial processes. The present project fits within a general problem addressed by Total on trying to predict, from various characteristics (or parameters/variables), different properties (as mechanical properties under stress) of welding in pipelines. The parameters can take various forms (quantitative or qualitative, ordinal or non-ordinal, real or Boolean) and are highly heterogeneous. They however need to be combined in order to obtain good prediction and one of the main challenges of this project is precisely to find the best way to combine different parameters for enhanced prediction and classification. In parallel, it is of course important to determine whether the different parameters are correlated or not, and to make use of possible correlations in the prediction/classification tasks. The developed method will have to be well adapted to large scale, heterogeneous datasets that are common to many different domains; it will furthermore be applied to the prediction of weld properties from paramters of the welding process.

During the project, the successful candidate will have to address the following points:

     1.	Study correlations between variables of many different types and extend existing models/methods to integrate all data types as well as their dependencies. The dataset collected by Total for studying welding in pipelines is unique by the diversity of the variables it relies on (product names, physical measures, manual annotations, …). This diversity constitutes a major challenge for all existing data analysis and machine learning methods. We will also try, whenever possible, to quantify the uncertainty associated with the representation of each data type;
     2.	In addition to the above-mentioned datasets, physical phenomena (as welding) are often described via equations that display relations between variables; they are also subject to simulations aimed at assessing their future evolution. One of the goals of the project will be to study how one can couple machine learning and physical equations and simulations to improve the accuracy of the prediction. This is a promising line of research that can bring together communities that do not usually work together;
     3.	Provide tools to help experts understand the results obtained by the models developed.

This will include:

   ●	Working with a team of computer scientists and mathematicians
   ●	Developing new machine learning/data analysis models
   ●	Implementing and testing the models developed

Required skills: Ph.D. or equivalent experience in computing, modeling, machine learning, statistics and applied mathematics

Application: The application should include a CV mentioning the publications, and any relevant documents. Candidates are encouraged to provide contact information to reference persons. Please send your application in one single pdf to Marianne.Clausel@imag.fr and Eric.Gaussier@imag.fr

Un poste d'ingénieur est ouvert dans le cadre du déploiement d'un système de prévision et d'analyse des pollutions environnementales. Le déploiement s'appuie à la fois sur les masses de données et sur la simulation numérique, de l'échelle mondiale à l'échelle urbaine. Le système est exigeant en terme de calculs et doit être optimisé. En particulier, l'étape de fusion des masses de données et des simulations numériques peut être très coûteuse et requiert une parallélisation adaptée. Les résultats des calculs sont notamment mis à disposition du grand public dans une application mobile sous Google Play et App Store, ce qui contraint à pouvoir répondre à des dizaines de milliers de requêtes par minute.

Le travail sera mené en collaboration étroite avec la start-up Ambiciti et dans le cadre d'un projet EIT Digital impliquant la PME Numtech (qualité de l'air, météorologie), Forum Virium (Helsinki), Inria@SiliconValley, The Civic Engine (San Francisco) et Cap Digital.

Le poste s'adresse à des ingénieurs, avec ou sans expérience, capables d'être productifs et de s'adapter dans un contexte dynamique et évolutif.

Industrial PhD position (CIFRE fundings) with TecKnowMetrix company located at Voiron.

Presentation of the company and the context:

TecKnowMetrix (TKM) is an innovative company created by the University Pierre Mendes France and INRA, based at Voiron. The company designs and develops methods and tools for the analysis of scientific and technological information. The application of these methods to large corpora enables it to deliver an overall view of a complex technological environment.

TecKnowMetrix has developed a software platform that can convert into a common format heterogeneous data sources. Indeed, the scientific and technical information is helpful in steering research public laboratories or innovative industrial groups. But its use is complicated by the diversity of sources, the heterogeneity of extremely important information formats and volumes that must be handled. This point refers to what is commonly called the “big data” topic on which the French actors must absolutely take strategic positions in the global competitive environment.

The TKM platform provides the ability to store and organize in a unique knowledge base that information from various sources. Once the database is created knowledge, TKM platform offers many ways to access relevant information: semantic analysis, data mining, statistical analysis or mapping information. TecKnowMetrix develops and uses this analysis and visualization methods to restore customers a synthetic vision and can be used directly in a given technological field.

Thesis project:

Introduction:

Automatic classification is a key issue in a “big data” environment (large and heterogeneous data), then it is vital to have powerful and efficient tools for automatic classification.

The consultants of the company, before starting a study, appraise records selected for their study and classified so as to analyze them. This classification step is time consuming but allows to provide relevant analysis to the client.

There are different ways for document classification, the longest but certainly the most reliable is that of reading each document to assign it to one or more classes. Methods of automatic or semi-automatic classification was introduced in TKM. They are based on document metadata or search queries. The results of these automated rankings can then be changed manually.

These methods pose increasingly problems for TKM. Given the amount constantly growing information to be processed, manual methods are no longer sufficient and semi-automatic classification can be manually corrected effectively. Added to this is the fact that each new mission, we must build a new classification. Finally, automatic methods currently used in TKM only consider the metadata but never textual content, gold, thanks to this ranking is more accurate and more relevant.

Goal :

The aim of the thesis is therefore to design an automatic classification method allowing:

- The extraction of keywords / concepts / phrases in a multi-source documentary corpus.

- Automatic creation of thesaurus based on the identified concepts (Aeronautics, Information Technology, Health, etc.)

- The document grouping in these thematic ontologies

It all making unsupervised manner.

issues:

One of the challenges of this project will provide a self-learning module based on the latest machine learning technologies can not only classify documents but also to create new thematic ontologies based on the identified concepts.

Other issues related to the profession of TKM will determine under what ontologies document to be classified. Indeed, the same document can be classified different technology classes (example: software for handling DNA sequences must logically be classified Health and Informatics)

Finally, the last challenge will be designing a module capable of handling multi-source documents whose language is very specific to each source.
