Coherent Wireless Link at 300 GHz with 160 Gbit/s Enabled by a Photonic Transmitter
We demonstrate a wireless link at 300 GHz using a fiber-coupled PIN photodiode as the transmitter. We achieved a maximum line rate of 160 Gbit/s with 32QAM modulation. The highest spectral efficiency was achieved with 64QAM at 8 GBaud, i.e. 48...
Overview of the Neural Network Compression and Representation (NNR) Standard
Neural Network Coding and Representation (NNR) is the first international standard for efficient compression of neural networks. The NNR standard contains quantization and an arithmetic coding scheme as core encoding and decoding technologies, as...
Towards Auditable AI Systems: From Principles to Practice
Auditing AI systems is a complex endeavour since multiple aspects have to be considered along the AI lifecycle that require multi-disciplinary approaches. AI audit methods and tools are in many cases subject of research and not practically...
Low-Loss Bragg-ReflectionWaveguides for On-Chip Time-Bin Entanglement
We fabricate low-loss AlGaAs Bragg-reflection waveguides for the creation of C-band photon pairs via parametric down-conversion. These photon pairs are used in a hybrid on-chip time-bin entanglement scheme.
xxAI - Beyond Explainable AI
This book takes next steps towards a broader vision for explainable AI in moving beyond explaining classifiers, to include explaining other kinds of models (e.g., unsupervised and reinforcement learning models) via a diverse array of XAI...
Explaining the Predictions of Unsupervised Learning Models
In this chapter, we review our recently proposed "neuralization-propagation" (NEON) approach for bringing XAI to workhorses of unsupervised learning. NEON first converts the unsupervised model into a functionally equivalent neural network so...
ECQx: Explainability-Driven Quantization for Low-Bit and Sparse DNNs
In this chapter, we develop and describe a novel quantization paradigm for DNNs: Our method leverages concepts of explainable AI (XAI) and concepts of information theory: Instead of assigning weight values based on their distances to the...
A Reference Model for Channel Sounder Performance Evaluation, Validation and Comparison
In this paper, we propose a detailed generic reference plane model for performance evaluation and system validation of radio channel sounders. It allows to abstractly describe a broad variety of channel sounder implementations and architectures...
Enhancing mmWave Devices with Custom Lenses
The mmWave band offers high bandwidths, but drawbacks such as limited range and susceptibility to blockage remain a challenge. In this paper, we take off-the-shelf mmWave devices in the 60 GHz band and combine them with custom lenses. As a...
