3D Deep Learning with TensorFlow 2

2020-03-09T17:36:48+00:00

In this blog post, we will first have a look at 3D deep learning with PointNet. Its creators provide a TensorFlow 1.x implementation of PointNet on Github, but since TensorFlow 2.0 was released in the meantime, we will transform it into an idiomatic TensorFlow 2 implementation in the second part of this post.

The world that we interact with each and every day is three-dimensional, but the majority of deep learning models process visual data as 2D images. However, there are

Transfer Learning for Text Classification with Siamese Networks

2020-03-19T10:02:10+00:00

In this blogpost, I want to present my master's thesis, which focused on transfer learning for text classification using Siamese Networks.

Text classification is a field in natural language processing (NLP), which assigns text to given classes. With applications in sentiment analysis, spam detection or i

Teach your Deep Neural Network to be aware of its epistemic and aleatory uncertainty. Get a quantified confidence measure for your Deep Learning predictions.

Artificial Intelligence—and machine learning in particular—have come a long way since their early beginnings. The widespread availability and affordability of powerfu

Multimodal Sequential Recommender Systems

2019-09-02T14:54:44+00:00

Sequential recommender systems are based on sequential user representations for a given user and sequence length. Each sequence consists of several items in temporal order. Sequential recommender systems aim at exploiting the temporal information that is hidden in the sequence of item interactions of the given user.

Since the invention of the internet, the availability and amount of information has increased steadily. Today we are facing problems of information overload and an ov

Digitize your Receipts using Computer Vision

2019-08-08T13:00:31+00:00

In this article I describe the steps and approaches to image recognition for receipt digitalization using computer vision. This is the basic functionality behind apps such as Google Lens, Evernote, PaperScan and taggun.io.

“Would you like the receipt?”—It’s hard to say no to that. Not because you actually want it (you may even throw it in the trash before exiting the store), but because

Summarizing Long Texts with Seq2Seq Neural Networks

2019-07-08T09:24:24+00:00

We extend state-of-the-art  sequence-to-sequence neural networks for summarization of long text across windows. By learning transitions, we are able to process arbitrarily long texts during inference.

This blog post describes my master thesis "Abstractive Summarization for Long Texts". We’ve extended existing state-of-the-art  sequence-to-sequence (Seq2Seq) neural net

Machine Learning Interpretability: Explaining Blackbox Models with LIME (Part II)

2019-06-04T16:14:33+00:00

The idea behind the model-agnostic technique LIME is to approximate a complex model locally by an interpretable model and to use that simple model to explain a prediction of a particular instance of interest.

This is the second part of our series about Machine Learning interpretability. We want to describe LIME (Local Interpretable Model-Agnostic Explanations), a popular t

The Mystery of Entropy: How to Measure Unpredictability in Machine Learning

2019-05-13T11:34:47+00:00

Entropy is a significant, widely used and above all successful measure for quantifying eg. inhomogeneity, uncertainty or unpredictability. It is an integral part of the latest machine learning models deployed on real-world data sets. In this article, I want to highlight the simplicity, beauty and meaning of entropy.

Robustifying Machine Perception for Image Recognition Systems: Defense Against the Dark Arts

2019-08-09T12:03:43+00:00

Despite their outstanding performance on various tasks, machine perception systems are not infallible. We highlight this problem by means of particular adversarial glasses that manage to force face recognition systems to make mistakes und we show how to achieve robustness against such attacks.

Despite the fact that machine perception systems achieve superhuman performance on different perceptual tasks, researchers have recently demonstrated that they are no
