ABSTRACT:

Automatic natural language understanding enables natural communication with computers and computer-assisted access to the content of large document collections. While classical approaches to artificial intelligence anticipate all possible situations and interactions in form of a fully specified dialogue model or ontology, they are hard to adapt to new domains and do not cope well with language change. In this talk, I will motivate an adaptive, purely data-driven approach to natural language processing. Illustrated by recent research prototypes, three stages of data-driven adaptation will be illustrated: feature/resource induction, induction of processing components and continuous data-driven learning. Finally, I will discuss current research and future directions regarding the integration of symbolic and statistical knowledge, interpretability of language processing components as well as advanced forms of information access.

 

BIO:

Chris Biemann obtained his doctorate in Computer Science / Natural Language Processing in 2007 from the University of Leipzig, before joining the San-Francisco-based semantic search startup Powerset, which was acquired by Microsoft to form the Bing.com search engine. In 2011, he got appointed as assistant professor for language technology in the computer science department at TU Darmstadt; since October 2016, Chris is professor for language technology at the University of Hamburg. His current research is focused on adaptive natural language processing in the cognitive computing paradigm, web-scale statistical semantic methods, machine learning from crowdsourcing signals and on applications in the humanities and social sciences.

ABSTRACT:

In the past an efficient and satisfactory image search was only possible by using a combation of keywords and low-level visual image features. Recently Convolutional Neural Networks (CNNs) have enabled automatic understanding of images. This results in a multitude of new applications and improved visual image search systems. This talk provides an overview of the different methods for image search, gives an overview of the principle of CNNs and shows how future image search systems could look like. We present a new approach to visually explore very large sets of untagged images. High quality image descriptors are generated using transformed activations of a convolutional neural network. These features are used to model image similarities, from which a hierarchical image graph is build. We show how such a graph can be constructed efficiently. Best user experience for navigating this graph is achieved by projecting sub-graphs onto a regular 2D-image map. This allows users to explore the image graph similar to navigation services.

 

BIO:

Prof. Dr. Kai Uwe Barthel studied Electrical Engineering at the Technical University of Berlin. At the university's department for image and signal processing he finished in 1996 his PhD thesis about fractal image compression. In 1998 he became head of R&D with LuraTech Inc. where hard- and software for image compression were developed. He also participated in the JPEG2000 standardization committee. His research topic of that time was the segmentation of documents for Mixed-Raster-Content compression. In 2001 he became a professor for visual computing at HTW Berlin, University of Applied Sciences. At HTW Berlin he is teaching courses such as image processing, computer vision, visual information retrieval, and machine learning. Main research topics are visual image search and automatic image understanding. In 2009 he founded pixolution, a company for visual image search. His latest research includes automatic keywording of images, image clustering and the development of visual image navigation systems such as www.picsbuffet.com

ABSTRACT:
Speech is arguably the most natural and important means for human communication. In recent years, speech has become more and more feasible and important also for human-computer interaction. As many speech communications devices like smartphones and hearing aids are portable or even wearable, they are frequently used in very noisy environments such as crowded restaurants, busy streets, or in a cafeteria. However, the noise and reverberation in such environments may make speech communication difficult or even impossible.

In the Signal Processing (SP) group, we focus on audio signal processing and in particular aim at making speech communication work more robustly in noisy and reverberant environments. To achieve this, we combine prior knowledge about the signal (e.g. speech), the environment (e.g. the room) and the sink (e.g. the human ear) with rigorous mathematical optimization procedures. In this talk, we will introduce the general concepts used for signal enhancement and highlight our recent contributions.
