Transaction connect analyze payment data to get a unified vision of customer behavior.Missions : - Enrich payment data algorithm (associate a transaction to a store, a city etc.) (algorithm in Python/R) - Analytics creation (Customer behavior, mall "showrooming" effect measure, Covid-19 impact on customer etc.) (Tableau) - Recommendation algorithm for shopping center retail space (Association rule learning)

Voltalis is a French company installing smart electrical enclosures in homes for free that - provide information to consumers about their energy consumption - will cut off electricity in order to curb peak needs on the grid, generating demand response capacity. it avoids opening expensive and polluting thermal power plantMissions : - forcasting electric consumption - modeling the cuts off - restructuring the electric consumption curve : frequency regulation, loads desynchronization (a patent has been filed) - developing operational tools (in R, excel), databases (mySQL) - realtime data stream cost reduction using survey sampling - other various studies (create France meteo database filled from the internet, estimate missing values in statistical data...)One patent filed : LISSAGE D'UNE COURBE DE CHARGE COMPRENANT UNE AGREGATION DE COURBES DE CHARGES ELEMENTAIRES (cf link)IT skills : R software (with package data.table for large data sets), shiny, mysql, git, jenkins, excel, VBA, some linuxStatistical and mathematical skills : lasso, mixtures, svm, signal processing, operations research

Mobilitas (3000 collaborators in 76 countries) is a group specialised in national and international mobility.Missions : - Analysis of consumer buying behavior - Price strategy implementation - Quantitative and qualitative analysis in collaboration with operational department - Implementation and administration of a CRM, user training - implementation of automation tools in Excel and VBA

RTE is the electricity transmission system operator of France. It is responsible for the operation, maintenance and development of the French high-voltage transmission system.Missions : - forecast french electric consumption at local scale in the medium and long term (about 4000 time series to study and forecast). Because of the variety of designs, we used an "adaptive model" : the LASSO regression.

Time series tutorials and practical work

Subject : local forecast of french electric consumption - Classification of electric consumption curves - Modelisation and simultaneous short term forecast

Subject : Exploratory study of the typology of various ranks of mature skinsWe had to identify the most relevant variables to differentiate three ranks of mature skins. We used two methodes : - Supervised classification - PLS regression

Subject : management of missing values in cancer quality of life questionnariesI had to create a methode of replacement of missing values in quality of life questionnaries. - Construction of a statistical model for the answers - Use of this model to replace the missing values - Creation of an operational macro on SAS
