However, the high throughput (gigasamples per second) and low latency requirements of this application domain pose a significant hurdle for adopting computationally demanding DNNs. In this article, we explore highly specialized DNN inference accelerator approaches on field-programmable gate arrays (FPGAs) for RadioML modulation classification. Using an automated end-to-end flow for the generation of the FPGA solution, we can easily explore a spectrum of solutions that optimize for different design targets, including accuracy, power efficiency, resources, throughput, and latency. By leveraging reduced precision arithmetic and customized streaming dataflow, we demonstrate a solution that meets the application requirements and outperforms alternative FPGA efforts by 3.5x in terms of throughput. Against modern embedded graphics processing units (GPUs), we measure >10x higher throughput and >100x lower latency under comparable accuracy and power envelopes.}}, author = {{Jentzsch, Felix and Umuroglu, Yaman and Pappalardo, Alessandro and Blott, Michaela and Platzner, Marco}}, journal = {{IEEE Micro}}, number = {{6}}, pages = {{125--133}}, publisher = {{IEEE}}, title = {{{RadioML Meets FINN: Enabling Future RF Applications With FPGA Streaming Architectures}}}, doi = {{10.1109/MM.2022.3202091}}, volume = {{42}}, year = {{2022}}, } @inproceedings{30389, abstract = {{Online solvers for a series of standard 1-D or 2-D problems in integrated optics will be discussed.

The Sonderforschungsbereich (SFB) 901 intends to provide the composition of software service On-the-Fly (OTF). The sub-project (B1) of the SFB 901 project deals with the parameters of service configuration. OTF Computing aims to eradicate the dependency on the requirement engineers for the software development process. However, there is no existing bidirectional chatbot solution that analyses user software requirements and provides viable suggestions to the user regarding their service. Previously, CORDULA chatbot was developed to analyze the software requirements but cannot keep the conversation’s context. The Rasa framework is integrated with the knowledge base to solve the issue, the knowledge base provides domain-specific knowledge to the chatbot. The software description is passed through the natural language understanding process to give consciousness to the chatbot. This process involves various machine learning models, including app family classification, to correctly identify the domain for user OTF service. The statistical models like naïve Bayes, kNN and SVM are compared with transformer models for this classification task. Furthermore, the entities (functional requirements) are also separated from the user description. The chatbot provides the suggestion of requirements from the preliminary service template with the support of the knowledge base. Furthermore, the generated response is compared with the state-of-the-art DialoGPT transformer model and ChatterBot conversational library. These models are trained over the software development related conversational dataset. All the responses are ranked using the DialoRPT model, and the BLEU score to evaluates the models’ responses. Moreover, the chatbot mod- els are tested with human participants, they used and scored the chatbot responses based on effectiveness, efficiency and satisfaction. The overall response accuracy is also measured by averaging the user approval over the generated responses.}}, author = {{Ahmed, Mobeen}}, title = {{{Knowledge Base Enhanced & User-centric Dialogue Design for OTF Computing}}}, year = {{2022}}, } @article{44328, abstract = {{In this paper, we study equivalences between the categories of quasi–coherent sheaves on non–commutative noetherian schemes.

These concepts usually differ in the number of self-inverse colors used. We introduce a unifying concept for this kind of coloring by assigning elements from symmetric sets to the vertices of the signed graphs. In the first part of the paper, we study colorings with elements from symmetric sets where the number of self-inverse elements is fixed. We prove a Brooks’-type theorem and upper bounds for the corresponding chromatic numbers in terms of the chromatic number of the underlying graph. These results are used in the second part where we introduce the symset-chromatic number χsym(G,σ) of a signed graph (G,σ). We show that the symset-chromatic number gives the minimum partition of a signed graph into independent sets and non-bipartite antibalanced subgraphs. In particular, χsym(G,σ)≤χ(G). In the final section we show that these colorings can also be formalized as DP-colorings.}}, author = {{Cappello, Chiara and Steffen, Eckhard}}, issn = {{0218-0006}}, journal = {{Annals of Combinatorics}}, keywords = {{Discrete Mathematics and Combinatorics}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Symmetric Set Coloring of Signed Graphs}}}, doi = {{10.1007/s00026-022-00593-4}}, year = {{2022}}, } @article{33950, author = {{Cappello, Chiara and Steffen, Eckhard}}, issn = {{0166-218X}}, journal = {{Discrete Applied Mathematics}}, keywords = {{Applied Mathematics, Discrete Mathematics and Combinatorics}}, pages = {{183--193}}, publisher = {{Elsevier BV}}, title = {{{Frustration-critical signed graphs}}}, doi = {{10.1016/j.dam.2022.08.010}}, volume = {{322}}, year = {{2022}}, } @inproceedings{34293, author = {{Wolters, Dennis and Engels, Gregor}}, booktitle = {{ICSOB'22 Companion Proceedings}}, publisher = {{CEUR}}, title = {{{Model-driven Design and Management of Professional Education Programmes}}}, volume = {{3316}}, year = {{2022}}, } @misc{45242, author = {{N., N.}}, title = {{{A Scalable and Extensible Architecture for a Crowd-Based Prototype Validation Platform}}}, year = {{2022}}, } @misc{45241, author = {{N., N.}}, title = {{{Conception and Implementation of a Situation-specific Design Thinking Tool}}}, year = {{2022}}, } @misc{45255, author = {{Anonymous, Anonymous}}, title = {{{ Comparison of Open Source Software in Quantum Computing from the Perspective of Software Development}}}, year = {{2022}}, }
