    "# OpenVINO optimizations for Knowledge graphs\n",
    "\n",
    "The goal of this notebook is to showcase performance optimizations for the ConvE knowledge graph embeddings model using the Intel® Distribution of OpenVINO™ Toolkit. <br>\n",
    "The optimizations process contains the following steps:\n",
    "\n",
    "1. Export the trained model to a format suitable for OpenVINO optimizations and inference\n",
    "2. Report the inference performance speedup obtained with the optimized OpenVINO model\n",
    "\n",
    "The ConvE model is an implementation of the paper - \"Convolutional 2D Knowledge Graph Embeddings\" (https://arxiv.org/abs/1707.01476). <br>\n",
    "The sample dataset can be downloaded from: https://github.com/TimDettmers/ConvE/tree/master/countries/countries_S1\n",
