Become a Machine Learning Engineer

If you want to dive into the technology behind computer vision and self driving cars, this is where to start.

In this module, you'll learn how to process data from image files and create convolutional neural networks (CNNs) to classify different types of images. After completing this module, you will have a solid understanding of why CNNs work and which CNN architectures to use for different tasks.

The code for this module is built around the TensorFlow framework, one of the premier frameworks for industry machine learning, and the Python pandas library for data analysis. Knowledge of Python and TensorFlow are prerequisites.

Image Recognition with Machine Learning

<h2>Chapter Goals:</h2>
<ul>
	<li>Set up an <code>Iterator</code> to extract data from a pixel array dataset</li>
</ul>


<h2>A. Using Iterator</h2>

<div id="section1_l5">
<p>The way we can extract the decoded image data from our <code>Dataset</code> is through a <code><a href="https://www.tensorflow.org/api_docs/python/tf/data/Iterator" target="_blank">tf.data.Iterator</a></code>. For a more in-depth look at <code>tf.data.Iterator</code>, check out the <a href='https://www.educative.io/collection/6083138522447872/5873588626259968/'>Industry Case Study</a> course on Educative.</p>
<p>We use the <code>get_next</code> function to obtain a <i>next-element tensor</i>, which is used for data extraction. Note that the next-element tensor doesn't have an actual value until we execute the iteration process using <code>tf.compat.v1.Session</code> (see next chapter).</p>
