Special Topics in Geometric Data Analysis
Guy Wolf (email@example.com)
Modern data analysis methods are expected to handle massive amounts of high dimensional data that are being collected in a variety of domains.
The high dimensionality of such data introduces numerous challenges, typically referred to as the “curse of dimensionality”,
which render traditional statistical learning approaches impractical or ineffective for their analysis. To cope with these challenges,
significant effort has been focused on developing geometric data analysis approaches that model and capture the inrinsic geometry of processed data,
rather than directly modeling their distribution. In this course we will explore such approaches and provide an analytical study of the models and algorithms they use.
We will start by considering supervised learning and distinguish classifiers that are based on geometric principles from statistical learning approaches, such as Bayesian classification.
Next, we will consider the unsupervised learning task of clustering data and contrast density based clustering from partitional and hierarchical clustering
methods that rely on metric spaces or graph constructions. Finally, we will consider more fundamental tasks in intrinsic representation learning,
with particular focus on dimensionality reduction and manifold learning methods, such as Isomap, Diffusion Maps, LLE, and tSNE.
Time permitting, the course will also include guest talks discussing recent development in related research areas.
The course will be suitable for CS, statistics, and applied math students interested in data science and machine learning.

Final grade composition:
The final grade in this class will be based on three components:
- 30% -- homework
- 45% -- final project report
- 25% -- final project presentation
- For the final project, students can work individually or form in small groups (at most 3 team members).
- If formed in a group, students should designate a person of contact for the group.
- Group members are expected to equally contribute to the project.
- Each group member will be expected to present their individual contribution after the final report is submitted.
- By Friday, Oct. 11, 23h59, each group should submit a project proposal (instructions will be announced/posted on StudiUM).
- Proposals are expected to span 2-3 pages and include at least the following sections:
- Project description & goals;
- Planned contributions of each team member;
- Used data / data sources.
- Projects should involve multiple methods applied to data analysis tasks chosen by each team (subject to approval of the submitted proposal), demonstrating understanding of underlying principles learned in class.
While discussion between students is not discouraged, homework is meant to be done & submitted individually.
