  4. 3. A Hardware Accelerated Low Power DSP for Recurrent Neural Networks

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Allan Andersen; Ilayda Yaman; [2020]
    Keywords : Digital Signal Processor; Hardware Accelerator; Machine Learning; Deep Learning; Recurrent Neural Networks; Gated Recurrent Unit; Technology and Engineering;

    Abstract : Recurrent neural networks (RNNs) have become a dominating player for processing of sequential data such as speech and audio. The reason for this, is the high accuracy that can be achieved with the more complex variants, such as the gated recurrent unit (GRU). READ MORE

  5. 4. DETECTION AND RESOLUTION OF VSI-DDOS ATTACKS FOR CONTAINERIZED CLOUDS

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Kristoffer Landfors; [2019]
    Keywords : ;

    Abstract : Very Short Intermi‹ent Distributed Denial of Service (VSI-DDoS) a‹ttack is a new form of DDoS a‹ttacks with potential to bypass many of the security measures used today and still severely damage the quality of service of web applications in cloud systems. Th‘e att‹acks consists of short bursts of legitimate packets which exploits vulnerabilities in the targeted system. READ MORE
