  • You find administrative information at UnivIS.
  • To get up-to-date information you should sign up for the course in the virtual campus.
  • At the first meeting (normally, first week of the start of lectures) we will give an introduction in suggested project topics. There is no official subscription beforehand.
  • A topic is usually worked on jointly by two to four students. Groups can be and mostly are formed in the first week of the course (for example related to topics of interests, etc.). Groups are established typically in the second week via posting in the vc (names and topic).
  • We strongly recommend students interested in writing a thesis in our group to participate in a project before!
  • Project topics presuppose knowledge and skills as introduced in the lecture/practive modules of the KogSys group.

Proposed Topics

15 ECTS project: Learning to Discriminate Categorial Feature Values -- An Intelligent Biology App for Tree Classification based on Leaf Forms

Bological classifications often rely on categorial -- often binary -- decisions about feature values. For example, trees can be classified by various charcateristics of their leafs such as round vs. oval form or smooth v. ripped edge, Most classification apps rely on a correct recognition of feature values by the user. That is, they ask for the value of one fature after the other to traverse a path in a decision tree. However, in many domains, it is difficult for a novice to recognize feature values correctly. For example, the edge might be wavey but the novice classifies it as rippled. Our goal is to develop a training app which can give hints to the user if she or he does not give the correctr feature value. Thus, the app will be a trainer for excat obersvation. As a first step, in the project, it is explored whether a deep learning classifier will be sufficiently accurate to rfecognize trees/leafs.

15 ECTS project: Deep Learning for Instance Segmentation

Supervisor: Johannes Rabold

Description: Comparison of two deep learning approaches for instance segmentation of plants.

Student: Louisa Pabst

Topic: Deep Learning for Semantic Segmentation

Supervisor: Johannes Rabold

Description:

In the project we will research applications of various deep learning architectures on the segmentation of instances in images. Identification of instances of a certain type (e.g. leaf, blossom) is prerequisite for phenotyping of plants. This research problem is in the context of a joint project with Fraunhofer.

Requirements:

  • Background in machine learning, e.g. from KogSys-ML-M

Admission policy:

  • Maximum of 20 participants with 5 groups
  • If more participants, priority is given to people that:
    • Passed the exam of KogSys-ML-M
    • are enrolled in a higher semester
    • intend to write their master's thesis at our chair (reason: we strongly recommend, taking a project in order prepare for the master's thesis)

We will meet in the first class, where you can state, that you want to attend the project. In the second week, we fix the participants.

15 ECTS project: Pain Recognition with Cartesian Genetic Programming

Description:Pain recognition has recently received significant attention. Over the past years a lot of work is done in this field, trying to find the one equation which defines the pain expression of all humans. Hence it is not a trivial challenge and it depends on a lot of factors. Different methods has been tried in automating pain recognition and some of them achieved good results. We chose Cartesian Genetic Algorithm(CGP) to identify pain by generating a Regular Expression(RegEx) that combines Action Units(AUs). We systematically review the mutation, fitness function and the evolutionary algorithm to achieve good results. The implementation steps are summarized and the statistical result are shown. There are two underlying motivations for us to write this paper. First, wheather it is possible to achieve a simple RegEx which correctly identifies pain expressions of all humans and second to find out how CGP fits with our problem and what results it achieves.

Topic: Relational Learning [Unvis: KogSys-Proj-B, vc-course]

Description: In the project, we want to compare classical feature-based learning (SVM) with relational learning (ILP). We will focus on domains which are more naturally modelled relationally (social networks, chemical structures, Michalski trains) and domains which can be modelled feature-based or relational (leaves of trees, lamps). For feature-based learning we will introduce methods for extracting features from relational representations. Approaches will be evaluated with respect to efficiency of learning, classification performance and comprehensibility of the learned hypotheses to humans. (Supervisor: Christina Zeller/Ute Schmid)

Description: Das Ziel dieses Projekts ist es ein System zu schaffen, welches anstrebt einen
Spielenden möglichst lange dazu zu bewegen mit diesem System zu interagieren
aus reiner Interesse und Spielspaß. Dazu wird der humanoide Roboter Pepper
als Hardware genutzt auf welchem ein Programm läuft, welches mit einer Per-
son das Gesellschaftsspiel Geistesblitz spielt und dabei auf diverse Ereignisse
während dem Spielen anhand eines internen Modells reagiert. (Supervisor: Christina Zeller/Ute Schmid)

Topic: AI Birds [Univis: KogSys-Proj-M, vc-course]

Joint Bachelor/Master-Project with SmartEnvironments.

Description: This project is a continuation of the successful AI Birds project from summer 2016. Goal is to program an intelligent agent who can play Angry Birds. Last year, the BamBirds team became world champion! The realised approach was mainly knowledge based with a reasoning system written in Prolog at the core. This year we want to extend the BamBird agent by an online learning component. (Supervisor: Ute Schmid)

Joint Project with SmartEnvironments: [VC-Course]

Topic: AI Birds – Qualitative Physics Knowledge and Strategy Learning to Master a Strategy Game

Description: Das Computerspiel Angry Birds wurde in der Künstlichen Intelligenz Forschung als ein Maßstab ausgewählt für intelligent mit Alltagswissen agierende Software. Um nämlich im Spiel erfolgreich sein zu können, muss ein grobes Verständnis physikalischer Zusammenhänge auf ein Spiel übertragen werden und strategische Entscheidungen unter Unsicherheit getroffen werden. Das macht Angry Birds schwieriger als frühe Arcade-Spiele oder rein strategische Spiele ohne Unsicherheit, also totales Wissen über Spielzustand und Spielmechanik wie Go. (Supervisor: Ute Schmid)

Topic: Lernen von Klassifikatoren zur Unterscheidung von Ekel und Schmerz aus der Mimik

Description: In diesem Projekt soll untersucht werden, wie sich Schmerz- und Ekelgesichtsausdrücke voneinander unterscheiden. Zur Verfügung stehen Daten eines Versuches der Physiologischen Psychologie, in dem Probanden Schmerz- und Ekelmimik zeigen. Die Daten liegen bereits in symbolischer Form vor (keine Bilder/Videos). Aus diesen Daten sollen abstrakte Beschreibungen (Klassifikatoren) für Schmerz- und Ekelgesichter gelernt werden. (Supervisor: Michael Siebers)

Joint Project with Mobi: Mining Vistior-Traces of Bamberg Zaubert

Es wird untersucht, wie durch die Analyse anonymer und anonymisierter Sensordaten Besucherbewegungen erfasst und vorhergesagt werden können. Hierzu sollen Verfahren des Machine Learnings eingesetzt werden, um typische Wege, Verweildauern und Geschwindigkeiten zu ermitteln; mit Hilfe dieser Information könnte dann beispielsweise vorhergesagt werden, dass in einer halben Stunde an einer gegebenen Stelle (z.B. Verpflegungstand) ein deutlicher Anstieg der Besucherzahlen zu erwarten wird. Diese Verfahren sollen mit einem Datenstrommanagementsystem kombiniert werden, um online relevante Ereignisse zu erkennen und an mögliche Adressaten (z.B. Betreiber des Verpflegungsstands) zu übermitteln.Die zentrale Frage, die mit Hilfe des Projekts beantwortet werden soll, lautet somit:Zu welchem Zeitpunkt hätte man welche Situationen bereits vorhersagen können? (Supervisors: Ute Schmid und Michael Siebers)

Topic: Enduser Programming with Igor: Learning Flashfill-Style String Transformations

Description: Enduser programming offers inductive learning systems which generalize programs from observed regularities in user behavior. For example, Flashfill offers support for complex string transformations in Excell. Flashfill is based on a domain-specific language and has an induction algorithm specifically designed for typical user tasks in Excell. Igor is a general, domain-independent inductive programming algorithm which allows to generalize recursive functional programs from input/output examples. In the project, we want to explore how to realize string transformations with Igor and compare its performance with Flashfill. (Supervisor: Ute Schmid)
