Spatial Data Science

The module Spatial Data Science introduces the basics of stochastics and descriptive statistics, and advancing through inferential statistics, machine learning, and neural networks. With practical applications in mind, we explore how probability, hypothesis testing, and statistical analysis form the backbone of data science, especially in the spatial context. The focus is on practical application, as well as understanding the principle of methods and their limitations. As we progress into machine learning, we examine different types of problems such as classification, regression, and clustering, in which we gain practical experience in handling tabular data. The challenge of overfitting and underfitting will be explored, along with methods to evaluate and prevent it. Moving into neural networks, we cover basic principles and apply various architectures, from simple feed-forward networks to convolutional and residual networks, which are especially valuable for analyzing spatial data like satellite imagery. Advanced concepts, such as hyperparameter optimization and fine-tuning models help to increase the performance of deep learning models.

Information

Ing. Christoph Schranz, MSc. BEd.

Lecturer
Salzburg Research

Christoph Schranz is a Data Scientist at Salzburg Research, working in the Human Motion Analytics group on wearable sensor data, biomechanics, and digital twin technologies.

Data Science has gained significant attention over the past few decades due to its successes in various areas, ranging from analyzing satellite images to predicting economic trends. This module aims to provide a clear and practical overview of Data Science, focusing on its applications in the spatial context. We will cut through the hype and offer concrete examples of how these concepts are used in practice. To start, we’ll define some of the most important terminology in the field.

The module Spatial Data Science requires more existing expertise than other elective modules. The level of the module is above average, as mastering mathematics skills at A-level and some experience with the Python programming language are ultimately expected. As Spatial Data Science encompasses a wide range of topics, from data visualization and inferential statistics to databases, algorithms, and advanced concepts in artificial intelligence, some chapters might be challenging. Additional resources for further study will be provided for certain topics.

This is an exclusively english language module, hence any kind of communication with the module lecturer should be in English. A discussion forum is maintained in Moodle in order to support efficient module instruction. You are requested to submit all your questions related to this module to this forum only. The lecturer will check all incoming comments on a regular basis. Theoretical concepts are complemented with practice oriented examples demonstrated with help of multimedia elements. Upon completion of the module students are requested to evaluate the module, which is a part of our quality assurance policy and practice.

Python, sklearn, PyTorch, Google Colab / Jupyter

Lecturer assessment reflects student’s achievements in this module and is conducted through assessing module assignments. Assignments (English language!) must be submitted in written format (.PDF) within the required time period. Each coding example (optionally also the others for consistency) must be written in a Jupyter notebook, the ipynb file can be exported as html or pdf. Exercises are designed to enforce students’ knowledge and skills. These should be completed to allow students to assess their own progress and are not included in the module assessment.
