<p>Hardware accelerated Function-as-a-Service (FaaS) enables cloud developers to
deploy inference functionalities [1] on Intel® IoT edge devices with
accelerators (CPU, Integrated GPU, Intel® FPGA, and Intel® Movidius™
technology). These functions provide a great developer experience and
seamless migration of visual analytics from cloud to edge in a secure manner
using a containerized environment. Hardware-accelerated FaaS provides the
best-in-class performance by accessing optimized deep learning libraries on
Intel® IoT edge devices with accelerators.</p>

<p>The AWS Greengrass samples are located at <a class="reference external" href="https://github.com/intel/Edge-Analytics-FaaS/tree/v1.0/AWS%20Greengrass">Edge-Analytics-FaaS</a>. This
guide uses the 1.0 version of the source code.</p>
<p>Clear Linux OS provides the following AWS Greengrass samples:</p>

networks such as AlexNet and GoogLeNet and publishes top-10 results on AWS*
IoT Cloud every second.</p>

<p>This AWS Greengrass sample detects objects in a video stream and
classifies them using single-shot multi-box detection (SSD) networks such
as SSD Squeezenet, SSD Mobilenet, and SSD300. This sample publishes
detection outputs such as class label, class confidence, and bounding box
coordinates on AWS IoT Cloud every second.</p>

<h4>Locate sample models</h4>
<p>There are two types of provided models that can be used in conjunction with
AWS Greengrass for this guide: classification or object detection.</p>
<p>To complete this guide using an image classification model,
download the BVLC AlexNet model files <a class="reference external" href="http://dl.caffe.berkeleyvision.org/bvlc_alexnet.caffemodel">bvlc_alexnet.caffemodel</a> and

are included with the computer-vision-basic bundle installation at
<code class="file docutils literal notranslate"><span class="pre">/usr/share/openvino/models</span></code>. These models are provided as an example;
you may also use a custom SSD model with the Greengrass object detection sample.</p>

<h4>Run model optimizer</h4>
<p>Follow the instructions in the <a class="reference external" href="https://software.intel.com/en-us/articles/OpenVINO-ModelOptimizer">Model Optimizer Developer Guide</a> for converting
deep learning models to Intermediate Representation using Model Optimizer. To
optimize either of the sample models described above, run one of the following commands.</p>
<p>For classification using BVLC AlexNet model:</p>
<div class="highlight-bash notranslate"><div class="highlight"><pre><span></span>python3 mo.py --framework caffe --input_model

<li>In the BVLC AlexNet model, the prototxt defines the input shape with
batch size 10 by default. In order to use any other batch size, the

<p>There are four options available for output consumption. These options are

<ol class="arabic">
<li><p class="first">IoT cloud output:</p>
<p>This option is enabled by default in the AWS Greengrass samples using the
<strong class="command">enable_iot_cloud_output</strong> variable. You can use it to verify the lambda

using the subscription topic specified in the lambda. (For example, topics
may include <strong class="command">openvino/classification</strong> for classification and <strong class="command">openvino/ssd</strong>
for object detection samples.) For classification, top-1 result with class
label are published to IoT cloud. For SSD object detection, detection
results such as bounding box coordinates of objects, class label, and
class confidence are published.</p>

<p>This option enables inference output to be streamed from the edge device
to cloud using Kinesis [3] streams when <strong class="command">enable_kinesis_output</strong> is set
