TEACHING

STATISTICS AND MACHINE LEARNING IN CIVIL ENGINEERING

Course objectives:

In the first parts of the course, the purpose is to provide the student with knowledge of probability and statistics, including the nature of random variables, fitting probability distributions to data sets (e.g., loads, material properties, temperature, etc.), and selecting statistical models for engineering analysis. The final parts of the course aim at providing insight into the use of statistical methods for the evaluation of safety and introducing the concepts of machine learning for classification and regression. Thus, the course focuses on statistical methods and the basics of machine learning applied for modelling in civil and architectural engineering. 

Learning Outcomes:

At the end of the course, the student is expected to be able to: 

  • Describe the concepts of uncertainty and probability 

  • Estimate and interpret simple summary statistics, such as mean, standard deviation, variance, median and quartiles as well as correlation 

  • Apply simple graphical techniques, including histograms, qq-normal plots, and box plots 

  • Identify and describe probability distributions 

  • Apply statistical concepts, such as the formulation of models, parameter estimation, construction of confidence intervals, hypothesis testing and model selection 

  • Apply and interpret simple statistical methods and machine learning within regression and analysis of variance 

  • Describe and apply the frequency analysis of extreme events 

  • Apply and interpret techniques of simulation for design 

  • Apply statistical tools for basic reliability analysis  

  • Assess statistics and machine learning in civil and architectural Engineering. 

RISK AND RELIABILITY IN CIVIL ENGINEERING

Course Objective:

This course aims to introduce the basic principles and fundamental techniques of risk and reliability analysis in engineering. After the course, the students will have a refreshed knowledge of probability theory and statistics to model uncertainties in engineering problems. The students will be able to do reliability analysis of engineering problems and to use risk assessment methods for decision making under uncertain conditions.

Learning Outcomes:

At the end of the course the student is expected to be able to:

- explain the concepts uncertainty, reliability, safety, and risk

- explain the various methods of component and system reliability and risk analysis

- explain the basic concepts of machine learning and information theory for uncertainty quantification and risk analysis

- model physical, statistical, model, and measurement uncertainties

- model the reliability by FORM/SORM methods surrogate models and simulation

- model system behavior and estimate the reliability of systems

- exemplify Bayesian statistical methods

- exemplify risk and reliability methods for probabilistic design of engineering problems

- evaluate reliability analysis of engineering problems and use risk assessment methods for decision making under uncertain conditions

- evaluate modeling of uncertainties and assessment of reliabilities and risk for engineering problems.
