| <h2>Overview<a class="headerlink" href="#Overview" title="Permalink to this headline">¶</a></h2> |
| <p>MXNet Gluon API comes with a lot of great features, and it can provide you everything you need: from experimentation to deploying the model. In this tutorial, we will walk you through a common use case on how to build a model using gluon, train it on your data, and deploy it for inference.</p> |
| <p>Let’s say you need to build a service that provides flower species recognition. A common problem is that you don’t have enough data to train a good model. In such cases, a technique called Transfer Learning can be used to make a more robust model. In Transfer Learning we make use of a pre-trained model that solves a related task, and was trained on a very large standard dataset, such as ImageNet. ImageNet is from a different domain, but we can utilize the knowledge in this pre-trained model to |
| perform the new task at hand.</p> |
| <p>Gluon provides State of the Art models for many of the standard tasks such as Classification, Object Detection, Segmentation, etc. In this tutorial we will use the pre-trained model <a class="reference external" href="https://arxiv.org/abs/1603.05027">ResNet50 V2</a> trained on ImageNet dataset. This model achieves 77.11% top-1 accuracy on ImageNet. We seek to transfer as much knowledge as possible for our task of recognizing different species of flowers.</p> |

| <p>Now we will apply data augmentations on training images. This makes minor alterations on the training images, and our model will consider them as distinct images. This can be very useful for fine-tuning on a relatively small dataset, and it will help improve the model. We can use the Gluon <a class="reference internal" href="../../api/gluon/data/index.html#mxnet.gluon.data.Dataset"><span class="std std-ref">DataSet API</span></a>, <a class="reference internal" href="../../api/gluon/data/index.html#mxnet.gluon.data.DataLoader"><span class="std std-ref">DataLoader API</span></a>, and <a class="reference internal" href="../../api/gluon/data/index.html#mxnet.gluon.data.Dataset.transform"><span class="std std-ref">Transform |
| API</span></a> to load the images and apply the following data augmentations: 1. Randomly crop the image and resize it to 224x224 2. Randomly flip the image horizontally 3. Randomly jitter color and add noise 4. Transpose the data from <code class="docutils literal notranslate"><span class="pre">[height,</span> <span class="pre">width,</span> <span class="pre">num_channels]</span></code> to <code class="docutils literal notranslate"><span class="pre">[num_channels,</span> <span class="pre">height,</span> <span class="pre">width]</span></code>, and map values from [0, 255] to [0, 1] 5. Normalize with the mean and standard deviation from the ImageNet dataset.</p> |
| <p>For validation and inference, we only need to apply step 1, 4, and 5. We also need to save the mean and standard deviation values for inference using other language bindings.</p> |

| <p>We will use pre-trained ResNet50_v2 model which was pre-trained on the <a class="reference external" href="http://www.image-net.org/">ImageNet Dataset</a> with 1000 classes. To match the classes in the Flower dataset, we must redefine the last softmax (output) layer to be 102, then initialize the parameters.</p> |
| <p>Before we go to training, one unique Gluon feature you should be aware of is hybridization. It allows you to convert your imperative code to a static symbolic graph, which is much more efficient to execute. There are two main benefits of hybridizing your model: better performance and easier serialization for deployment. The best part is that it’s as simple as just calling <code class="docutils literal notranslate"><span class="pre">net.hybridize()</span></code>. To know more about Gluon hybridization, please follow the <a class="reference internal" href="../packages/gluon/blocks/hybridize.html"><span class="doc">hybridization |

| <p>In the previous example output, we trained the model using an <a class="reference external" href="https://aws.amazon.com/ec2/instance-types/p3/">AWS p3.8xlarge instance</a> with 4 Tesla V100 GPUs. We were able to reach a test accuracy of 95.5% with 40 epochs in around 12 minutes. This was really fast because our model was pre-trained on a much larger dataset, ImageNet, with around 1.3 million images. It worked really well to capture features on our small dataset.</p> |
