Open Thesis Topics

Static Typing for Snap!

Snap! is an educational visual programming language in the tradition of Scratch, but extended with features for abstraction, such as higher-order functions and user-defined data types. The purpose of this thesis is to add a static type system with type inference to Snap, in the style of Hindley-Milner type systems – the backbone of static typing in functional programming. The main challenge of this thesis, beyond implementing the type system, is to design visual metaphors for static typing that fit to the pedagogy of Snap and adapt the type Hindley-Milner system to the particular features offered by Snap!.

Web-basierte Visualisierung mittelalterlicher Musiknotation

MEI (Music Encoding Initiative) hat sich inzwischen als Format zur Musik-Codierung in der musikwissenschaftlichen Forschung etabliert. Es deckt neben der gebräuchlichen Musiknotation (Common Western Music Notation) auch Notationsformen älterer Musik (z.B. die sogenannten Neumen des Gregorianischen Chorals) ab. Das MEI Neumes Module wurde in Zusammenarbeit zwischen dem WSI und dem Musikwissenschaftlichen Institut Tübingen im Projekt Tübingen entwickelt. Eine Diplomarbeit am WSI (Gregor Schräder) entwickelte als web-basiertes Visualiertungstool den MEI Neumes Viewer. In der Arbeit soll die bisherige im MEI Neumes-Viewer verwendete “Eierkohlen”-Notation um weitere mittelalterliche Notationen (Neumennotation, Quadratnotation) erweitert werden. Als Vorbild könnte der Open-Source TeX-Dialekt Gregorio dienen.

Probabilistic Programming for Algorithmic Trading

Probabilistic programming is often advertized as “democratizing machine learning”, because it provides a very simple but expressive model of statistical inference. The purpose of this thesis is to validate that claim by applying it to algorithmic trading of securities. More specifically, we want to apply it for “auto-tuning” of parameters for trading strategies. In the thesis, no actual trading will take place, but we will evaluate the approach with historical ticker data.

Contract inference for relationally parametric polymorphic contracts

Guha et al have developed a way to specify relationally parametric polymorphism in contracts and check conformance at runtime. These ideas were realized in the Racket programming language. Currently, the utility of parametric contracts is limited due to the fact that parametric contracts must be instantiated explicitly in many circumstances; implicit instantiation only works for primitive types.

Embedded Probabilistic Programming with Continuous Variable Distributions

Probabilistic programming languages are programming languages which have special support to describe probabilistic models, and then perform inference in these models. They are attractive because they unify the expressive power of a general-purpose programming language with probabilistic modeling and reasoning.

DSLs for Machine Learning

We are collaborating with Christopher Ré from Stanford University to improve the interface to the DeepDive machine learning system. More specifically, we aim to phrase the interface to DeepDive as an embedded domain-specific language with the eventual goal to integrate machine learning so closely and seamlessly into ordinary programs that it is as simple to define a function or data structure via machine learning than to define a function via ordinary programming. The goal of this thesis is to to make the first steps towards that goal. Concretely, the first step would consist in embedding DeepDive into a statically typed programming language such as Scala.

Finished Thesis Topics

Software-supported piano practice

Pianists perform a variety of exercises to improve the evenness and precision of their playing, including scales, arpeggios, and octaves. The purpose of this thesis is to develop an application that supports pianists in two ways: 1) Training the ear to identify uneven scales, arpeggios etc., and 2) Analyze the exercises of the pianist to identify flaws in the execution of the exercises.

Recording student progress in DrRacket

The purpose of this thesis is to develop a plug-in for the DrRacket development environment that will monitor and log the activity of students. The (appropriately anonymized) collected data will then be used for the scientific evaluation of how beginning programmers work. The main focus of this work is on collecting and representing the developer activity in such a way that interesting analyses can be defined on top of it.

Entwicklung eines Systems zur Suche von DIY-Projektbeschreibungen mit Bildern und Fotos

Das im Rahmen des “Tübinger Softwareprojekts” entwickelte System für Schritt für Schritt Anleitungen soll in dieser Bachelor-Arbeit um eine neuartige Such-Funktionalität erweitert werden. Wir gehen in Zukunft davon aus, dass Nutzer Projektbeschreibungen nicht mehr durch Texteingabe suchen, sondern eher nach Fotos oder Bildern im Internet. Ein Ansatz zur Implementierung der Funktionalität besteht darin, zuerst das Bild zu Verschlagworten und die so erhaltenen Schlagwörter dann als Eingabe einer „klassischen“ Suchmaschine zu verwenden. Hierzu gibt es bereits verschiedene Technologien. Die Aufgabe der Bachelor-Arbeit ist es nun, die vorhandenen Technologien zu identifizieren, zu analysieren und geeignete Technologien auszuwählen. Auf Basis von zu entwickelnden System- und Interaktionskonzepten soll die Implementierung bzw. Systemintegration erfolgen. Ziel ist die prototypische Darstellung einer Suche nach einer DIY-Projektbeschreibung mithilfe eines gemachten Fotos.

Zusätzlich muss der Assistent per API in das System eingebunden werden.

Automatic locality-friendly array interface extension of numerical functions through C++ template metaprogramming

Numerical functions often need be invoked on views of vectors or matrixes, derived by selecting some elements or by pre-transforming them. For instance, one might want to prescale matrix elements before applying an existing FFT algorithm on them. Often this must be done by copying the elements to a separate array, and then invoking the original FFT algorithm, but this procedure is not efficient because it uses additional space and therefore has higher impact on data caches.
