Discovering the Correlation Formula between 3D Accelerometer Data and Heart Rate

Prerequisites

• Download the relevant portions of data files - HR and ACC files from https://physionet.org/content/big-ideas-glycemic-wearable/1.1.2/ (HR and ACC)

• VulkanSDK-1.3.268.0

  Windows

VulkanSDK-1.2.182.1-Installer.exe --accept-licenses --default-answer --confirm-command install com.lunarg.vulkan.32bit com.lunarg.vulkan.sdl2 com.lunarg.vulkan.glm com.lunarg.vulkan.volk com.lunarg.vulkan.vma com.lunarg.vulkan.debug com.lunarg.vulkan.debug32

• linux (ubuntu jammy):

    wget -qO- https://packages.lunarg.com/lunarg-signing-key-pub.asc | sudo tee /etc/apt/trusted.gpg.d/lunarg.asc
    sudo wget -qO /etc/apt/sources.list.d/lunarg-vulkan-1.3.268-jammy.list https://packages.lunarg.com/vulkan/1.3.268/lunarg-vulkan-1.3.268-jammy.list
    sudo apt update
    sudo apt install vulkan-sdk

• compile shaders

glslc plus.comp -o plus.spv 
glslc minus.comp -o minus.spv
glslc multiply.comp -o multiply.spv

make sure you are using 64bit architecture on Windows
