  1. 1. Towards Performance Evaluation and Future Applications of eBPF

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Manideep Gunturu; Rohan Aluguri; [2024]
    Keywords : eBPF; XDP; Iptables; Filtering; Performance evaluation;

    Abstract : Extended Berkeley Packet Filter (eBPF) is an instruction set and an execution environment inside the Linux kernel. eBPF improves flexibility for data processing and is realized via a virtual machine featuring both a Just-In-Time (JIT) compiler and an interpreter running in the kernel.

  3. 2. Kernel Methods for Regression

    University essay from Linnéuniversitetet/Institutionen för matematik (MA)

    Author : Tom Lennart Rossmann; [2023]
    Keywords : Kernel Methods; Regression; Ridge Regression;

    Abstract : Kernel methods are a well-studied approach for addressing regression problems by implicitly mapping input variables into possibly infinite-dimensional feature spaces, particularly in cases where standard linear regression fails to capture non-linear relationships in data. Therefore, the choice between standard linear regression and kernel regression can be seen as a tradeoff between constraints on the number of features and the number of training samples. READ MORE

  4. 3. An Algorithm for Sampling from Bandlimited Circular Probability Distributions

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Mattias Olofsson; [2023]
    Keywords : Matematisk Statistik;

    Abstract : In this Bachelor thesis, a novel algorithm for sampling from bandlimited circular probability distributions is presented. The algorithm leverages results from Fourier analysis concerning the Fejér kernel to simulate data with some desired probability distribution, realized as a sum of data sampled from a discrete distribution and a small continuous perturbation sampled from the Fejér kernel distribution.

  5. 4. A Multi-camera based Next Best View Approach for Semantic Scene Understanding

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Anton Persson; [2023]
    Keywords : Next Best View; NBV; Semantic Scene Understanding; Robotics;

    Abstract : Robots are becoming more common; robotics has gone from bleeding-edge technology to an everyday topic that families discuss around thedinner table.The number of robots in the industry is growing, which means thatthe demand and need for robots to understand the environment it isworking in is also growing.

  6. 5. A Conjugate Residual Solver with Kernel Fusion for massive MIMO Detection

    University essay from Högskolan i Halmstad/Centrum för forskning om tillämpade intelligenta system (CAISR)

    Author : Ioannis Broumas; [2023]
    Keywords : MIMO; massive MIMO; GPU; CUDA; Software Defined Radio; SDR; MMSE; ZF; zero-forcing; parallel detection; iterative methods; conjugate residual; parallel computing; kernel fusion;

    Abstract : This thesis presents a comparison of a GPU implementation of the Conjugate Residual method as a sequence of generic library kernels against implementations ofthe method with custom kernels to expose the performance gains of a keyoptimization strategy, kernel fusion, for memory-bound operations which is to makeefficient reuse of the processed data. For massive MIMO the iterative solver is to be employed at the linear detection stageto overcome the computational bottleneck of the matrix inversion required in theequalization process, which is 𝒪(𝑛3) for direct solvers.
