hela Sverige Currently in Siemens Energy, almost all the machine learning use cases are based on time-series data from various sensors on turbines across the world. There are hundreds of models running for sales operation planning, forecasting power demand, unit performance, efficiency and so on to increase the business value of our customers. Multiple models are maintained for different horizon forecasts. One of the major steps forward in this offering is the reduction in number of models and hence the cost of maintaining these models. Further improvement in forecast accuracy of the existing time series estimators by embedding more information (temporal/non-temporal hierarchies) from the sensors into the models is also in the focus.
Your role in this project is to conduct an empirical research to build and benchmark hierarchical time series forecasting models that can predict multi step ahead. Your job will also focus on investigating about the business impact of your new proposed solution, and how it is useful for the company in comparison with the current forecasting models.
LET'S TALK ABOUT YOU
Your profile
* Academic background in energy systems, engineering, computer science, statistics, machine learning, mathematics, or another relevant field.
* Curiosity about data analytics (especially in time series analysis) and you must have programming skills (preferable: Python, R).
* Knowledge of machine learning/deep learning/time series-oriented libraries (scikit-learn, caret, theif, hts, mlr, keras, tensorflow, pytorch etc...), data handling libraries (Pandas or tidyverse) is meritorious.
* We consider meritorious a GitHub record with univariate, multivariate time series forecasting projects and deep learning.
Your responsibilities
* Literature Review of existing methodologies used for embedding hierarchical information in the time series forecasts and time series/deep learning models for multiple horizon predictions.
* Perform a comparative study on the most used time series forecasting models and investigate their relative performance using real sensor data from gas turbines.
* Compare hierarchical forecasting approaches for different base forecasting models and reconciliation methods.
* Benchmark the accuracy of Hierarchical Time Series (HTS) models and deep learning models for multi forecast horizons against existing traditional baselines (prophet)
* Understand and present the business impact of your solution in comparison to company's current forecasting models- in terms of performance, resources, cost, etc.
Your opportunities for personal growth:
* A chance to put your specialist knowledge to practical use and take an application-oriented approach to work.
* A conducive workplace and supervision to learn and understand the practical challenges of large-scale machine learning, time-series forecasting and come up with innovative ways to tackle them.
* A chance to create an impact in current processes in Siemens Energy by means of actively contributing to research on improvement of existing forecasting models.
