Available MSc, BSc and PhD Semester Projects

  • Distributed Machine Learning using PyTorch, TensorFlow and other frameworks
    (Practical project)
    The goal in this project is to build and evaluate robust, open-source, system-adaptive and correct implementations of distributed optimization schemes for machine learning, as part of our MLbench open source project. Required skills are basic experience with open source / python, and either knowledge on writing efficient numerical code, or theoretical interest in optimization methods for DL. Contact: Martin Jaggi
  • Learning Multilingual Text Representations
    (Algorithm design and experiments), building on top of sent2vec and other models (PyTorch code available also), we investigate the quality and efficiency of multilingual representations of words, sentences and documents. Contact: Prakhar Gupta
  • Efficient Deep Learning Training with non-iid data
    In current distributed SGD algorithms (centralized/decentralized), when data are non-iid distributed between workers (e.g. every worker has training examples only from one class), the generalization of final solutions is often very poor. The project is aimed to experimentally understand the reasons and possible solutions of this problem. Contact: Tao Lin and Anastasia Koloskova
  • Adaptive Importance Sampling to Speed Up SGD and Related ML Algorithms
    (Theory and/or practical project)
    Using more important training examples more often during training is a promising direction for speeding up SGD. As the importances of the samples are changing, finding good adaptive distributions is the main challenge here. Importance sampling can be explored for coordinate descent (CD) and stochastic gradient descent (SGD) type of algorithms. (Related papers: Safe Bounds, Adaptive Sampling, DL applicationContact: Sebastian Stich
  • Text Steganography using Neural Networks
    (Practical project)
    See paper here. As a next step, we want to explore extensions to a joint adversarial training setting for steganography. Contact: Andreas Hug
  • Computational Aspects of Learning Text Sequence Representations
    (Algorithm design and analysis), building on top of sent2vec (PyTorch code available also). Contact: Prakhar Gupta
  • Distributed Methods in Machine Learning
    (Theory and implementation)
    Study the convergence of optimization algorithms (like CD, SGD, SVRG) in a distributed or decentralized setting. Contact: Sebastian Stich

    • Distributed SVRG: design of a new algorithm & convergence analysis. (Related paper: k-SVRG).
    • Decentralized Local SGD: convergence theory (Related paper: local SGD)
    • Decentralized SGD with Communication Compression: can we extend the scheme to asynchronous communication? (Related paper: Choco SGD)
    • Decentralized SGD on many nodes: how do decentralized methods scale on many (> 10k) nodes? (Related paper: Choco SGD)
    • Adaptive schemes for communication compression (Related papers: sparsified SGD, Normalized Gradients)
    • Basis Pursuit, explore new ideas for communication efficient SGD
  • Acceleration and Momentum for Deep Learning
    “Momentum” is indispensable for fast convergence of SGD. In this project, we try to have a new look at different momentum-schemes. Contact: Sebastian Stich
  • Robust Training Methods [Taken for autumn 2019]
    (Implementation and Theory)
    As adversarial examples and robust training methods become more and more understood (Robust training, Aversarial examples are features) efficient training methods become increasingly important. The first part of the project consists of setting up a well-documented training and testing environment, the second part could have a theory focus or could consist of an experimental study. Contact: Sebastian Stich
  • Model-Parallel Training of Deep Learning
    • (Practical project), please contact Tao Lin for more details.
    • (Theory project) efficient training methods, such as e.g. Pipe Dream rely on ‘asynchronous back-propagations’. Can we understand the effect this asynchronity from a theoretical point of view? Contact: Sebastian Stich
  • Low Precision Arithmetic
    (mostly theory)
    Most hardware DL accelerators rely on limited precision arithmetic. We start by compiling a survey of existing techniques (with corresponding error bounds) and will explore the possibilities of error feedback sparsified SGD). Contact: Sebastian Stich

Interdisciplinary Projects

  • ML for Advanced Manufacturing

In the context of manufacturing nano-scale sensors consisting of individual carbon nanotubes, we use a machine learning approach to classify Raman spectroscopy data. Based on a large labelled dataset of 1-dimensional Raman Spectroscopy measurements, we detect for each measurement position the presence of a healthy nanotube as well as its orientation. In addition to standard ML techniques, we also employ unsupervised signal representation learning based on CNNs in a semi-supervised setting.

  • A Machine-Learning Platform for Emerging Viral Diseases in Africa

Background: In the wake of the recent Ebola and Zika epidemics, it is becoming clear that infectious disease surveillance in Africa should include highly sensitive screening tools with the capacity to identify unrecognized viral species, unexpected variants or emerging pathogens with epidemic potential. However, population-level, high-resolution, virome-wide genetic sequencing is financially and practically impossible in countries with limited resources.

Aims: This project aims to develop an intelligent diagnostic model able to short-list the most probable viral causes of a patient’s’ fever based on simple and inexpensive clinical and laboratory tests.

1) Based on our detailed clinical dataset of 2500 pediatric and adult febrile patients in Africa, implement and evaluate different machine-learning models for predicting the diagnosis and possible causal viruses of fevers in Africa.

2) Create a model based on simple diagnostic source data and check if it is competitive with the virus results from existing high-resolution genetic sequencing results. We will also study the evolution over time using data from new cohorts of patients.

3) Integrate the resulting system into an easy-to-use mobile app (existing template) with a centralised database for real-world use in developing countries.

  • Dream Prediction from EEG data

The goal of this project is to apply machine learning to predict when (and what!) a sleeper is dreaming based on electroencephalogram (EEG) time series. We have access to a large dataset consisting of 500 Hz signals from 256 electrodes over the 2 minutes before awakening, labeled by whether the sleeper remembered a dream or not. We will propose to use a convolutional neural network (CNN) to classify these EEG time series.
