Top-tier conferences in machine learning or computer vision generally require state-of-the-art results as baseline to assess novelty and significance of the paper. Unfortunately, getting state-of-the-art results on many benchmarks can be tricky and extremely time-consuming — even for rather simple benchmarks such as CIFAR-10. In this article, I want to share PyTorch code for obtaining 2.56% test error on CIFAR-10 using a Wide ResNet (WRN-28-10) and AutoAugment as well as Cutout for data augmentation.
PyTorch is a great tool to do deep learning research. However, when running large-scale experiments using various architectures, I always come across this one problem: How can I run the same experiments, evaluations or visualizations on models without knowing their architecture in advance? In this article, I want to present a simple approach allowing to load models without having to initialize the right architecture beforehand. The code of this article is available on GitHub.
Tensorboard is a great tool to monitor and debugg deep neural network training. Originally developed for TensorFlow, Tensorboard is now also supported by other libraries such as PyTorch. While the integration in PyTorch was shaky in the beginning, it got better and better with more recent releases. In this article, I want to discuss how to use Tensorboard for monitoring training with PyTorch. The article’s code is available on GitHub.
Since I worked on confidence-calibrated training (CCAT) some years ago, CCAT has been evaluated using novel attacks. In this article, I want to share some updated results and numbers and contrast the reported numbers with newer experiments that I ran.
I always used aspell to spell check papers. I did not care about setting up a dictionary of words that aspell does not recognize due to time pressure. As papers usually involve few LaTeX files, this was an OK process. For my PhD thesis, however, I needed a more automatic and thorough process. This is because more files are involved and I had to spell check multiple times, several weeks or months apart, throughout the process. In this article, I want to share a semi-automatic but thorough process based on aspell and TeXtidote that worked well for me.
Generally, papers are written to be published at conferences or journals. While some journals care about the LaTeX source used to compile the submitted papers, most venues just expect compiled PDFs to be submitted. However, ArXiv always requires the full LaTeX source to be compiled on the ArXiv servers. As the LaTeX source of every ArXiv paper can be downloaded, this usually involves removing all comments, unused figures/files and “flattening” the directoy structure as ArXiv does not handle subdirectories well. In this article, I want to share two simple scripts that take care of the latter two problems: removing unused files and flattening.
Conducting PhD research can be a long endeavor, involving much more than the publications listed on Google Scholar. As I recently submitted my thesis, in this article, I look back on my time as PhD researcher in terms of numbers. This way, I hope to shed some light on what a PhD can look like in terms of everyday work.
In 2018, I was half a year into my PhD and wrote an article about choosing the right PhD program, which I personally found to be incredibly difficult even though I only had few options to decide between. This article is an updated version, preserving most of my original opinions and advice and adding some perspectives having finished my PhD in the meantime.
In March this year I finally submitted my PhD thesis and successfully defended in July. Now, more than 6 months later, my thesis is finally available in the university’s library. During my PhD, I worked on various topics surrounding robustness and uncertainty in deep learning, including adversarial robustness, robustness to bit errors, out-of-distribution detection and conformal prediction. In this article, I want to share my thesis and give an overview of its contents.
In July this year I finally defended my PhD which mainly focused on (adversarial) robustness and uncertainty estimation in deep learning. In my case, the defense consisted of a (public) 30 minute talk about my work, followed by questions from the thesis committee and audience. In this article, I want to share the slides and some lessons learned in preparing for my defense.
