Get familiar with the basic machine learning techniques used in natural language processing.

Mastering Natural Language Processing

This module was created by AdaptiLab, a company specializing in evaluating, sourcing, and upskilling enterprise machine-learning talent. It’s built in collaboration with industry machine learning experts from Google, Microsoft, Amazon, and Apple.

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. A knowledge of Python and TensorFlow is required for this module.

Natural Language Processing with Machine Learning

<h2 class="section-title">Chapter Goals:</h2>
<ul>
	<li>Classify input text using the BiLSTM model</li>
</ul>


<h2>A. Calculating predictions</h2>

<div id="section1_l6" class="collapse show">
<p>our BiLSTM is used to classify sentiment in text as either positive or negative. Since there are only two classes, this is binary classification. For binary classification, we apply the sigmoid function on the model's logits to obtain a probability for the input text. The probability refers to the likelihood that the input text is labeled "positive" (i.e. label <code>1</code>), and we can simply round the probability to the nearest integer to obtain the model's prediction.</p>
