Annual Nonlinear Analysis Workshop
2018 NONLINEAR ANALYSIS WORKSHOP- JULY 30-AUGUST 3
Participants will learn how to use nonlinear methods to analyze real biological data by first learning about the underlying mathematics of each nonlinear method in a simple and friendly fashion. Instructors will use class discussions and hands-on practice to facilitate understanding of the material covered in the lectures. Participants with varied backgrounds are welcome.
- At the completion of the course, participants should be able to:
- 1. Understand the basic concepts in nonlinear dynamics and chaos.
- 2. Describe what each nonlinear method measures.
- 3. Understand the basic mathematical algorithm behind each nonlinear method.
- 4. Understand parameter selection for each nonlinear analysis method.
- 5. Understand how to apply different nonlinear methods to biological time series data.
- 6. Know which nonlinear methods are used to analyze biological time series data.
- 7. Understand the uses and applications of nonlinear analysis.
- 8. Understand limitations of nonlinear methods.
- 9. Apply nonlinear analysis in professional settings.
PREREQUISITES FOR THE COURSE
Knowledge of college algebra, basic trigonometry, basic statistics and basic computer skills are needed to be successful in this workshop. This course is designed to be a comprehensive introduction to nonlinear analysis tools. Researchers, clinicians, and graduate students of all levels are encouraged to attend.

PREVIOUS COURSE SCHEDULE
CONTENT AND ORGANIZATION
Day 1: Introduction to Dynamical Systems
This day is a basic introduction to many important concepts that will be referenced during the remainder of the week.
Day 2: Fractal Analysis
This day is a discussion of the basis of fractals, what they are and how they may be analyzed. Several techniques are introduced, including the advantages or shortcomings of the different algorithms.
Day 3: State Space Reconstruction and Lyapunov Exponent
You will be introduced to the concept of state space reconstruction based on Taken's theorem. In addition, the mathematical basis of Lyapunov exponent will be introduced as well as two algorithms for its calculation for biological time series, Wolf's and Rosenstein's.
Day 4: Entropy and Surrogation
On Day 4, there is a full discussion about entropy, the mathematical basis of entropy and why it has been "approximated" for use in biology. Different algorithms are discussed including: approximate, sample, and symbolic. In addition, this day includes a discussion of several algorithms of surrogation analysis.
Day 5: Examples and Applications
The last day of the week will cover recurrence quantification analysis as well as cross-recurrence quantification analysis.
Topics covered throughout the week:
|Introduction to time series||Reconstruction of the state
|Different Nonlinear Methods|
|Lyapunov Exponent Correlation
|Capacity Dimension||Fractal Analysis Topics|
|Hurst Exponent||Detrended Fluctuation Analysis
|Shannon’s Entropy||Approximate Entropy||Sample Entropy|
|Symbolic Entropy||Surrogate methods||Theiler’s Algorithms|
|Small Shuffle Surrogate
- Lecture notes: lecture notes will be distributed during the course. Participants are encouraged to use data from their own laboratory during the hands on sessions, however sample data from the Biomechanics Research Building will also be provided to practice using the nonlinear tools.
- Laptops with necessary software are provided during the course of the workshop.
- Breakfast and snacks each day.
- $10/day for lunch to use on UNO's campus.
- Participants will be given a copy of all software and slides.
