# Text classification using CNN

In this article, we are going to do text classification on IMDB data-set using Convolutional Neural Networks(CNN). We will go through the basics of Convolutional Neural Networks and how it can be used with text for classification.

• Basics of Convolutional Neural Networks
• How to use CNN for text classification?
• Code Demonstration

## Convolutional Neural Networks

Let’s first understand the term neural networks. In a neural network, where neurons are fed inputs which then neurons consider the weighted sum over them and pass it by an activation function and passes out the output to next neuron.

Now, a convolutional neural network is different from that of a neural network because it operates over a volume of inputs.

Each layer tries to find a pattern or useful information of the data.

An example of multi-channel input is that of an image where the pixels are the input vector and RGB are the 3 input channels representing channel.

This is what the architecture of a CNN normally looks like. It will be different depending on the task and data-set we work on. There are some terms in the architecutre of a convolutional neural networks that we need to understand before proceeding with our task of text classification.

Convolution: It is a mathematical combination of two relationships to produce a third relationship. Joins two sets of information.

Convolution over input: We slide over input data the convolution to extract features by applying a filter/ kernel (both can be used interchangeably). This is important in feature extraction. There are some parameters associated with that sliding filter like how much input to take at once and by what extent should input be overlapped.

• Stride: Size of the step filter moves every instance of time.
• Filter count: Number of filters we want to use.

When we are done applying the filter over input and have generated multiple feature maps, an activation function is passed over the output to provide a non-linear relationship for our output.

An example of activation function can be ReLu.

Now, we generally add padding surrounding input so that feature map doesn’t shrink. If we don’t add padding then those feature maps which will be over number of input elements will start shrinking and the useful information over the boundaries start getting lost.

It also improves the performance by making sure that filter size and stride fits in the input well.

We are not done yet. We need something that helps us to reduce this high computation in the CNN and not overfit the data. Overfitting will lead the model to memorize the training data rather than learning from it.

We use a pooling layer in between the convolutional layers that reduces the dimensional complexity and stil keeps the significant information of the convolutions.

One example is of max pooling layer. It finds the maximum of the pool and sends it to the next layer as we can see in the figure below.

Sometimes a Flatten layer is used to convert 3-D data into 1-D vector.

In a CNN, the last layers are fully connected layers i.e. each node of one layer is connected to each node of the other layer.

## pdf2gerb

Perl script converts PDF files to Gerber format

Pdf2Gerb generates Gerber 274X photoplotting and Excellon drill files from PDFs of a PCB. Up to three PDFs are used: the top copper layer, the bottom copper layer (for 2-sided PCBs), and an optional silk screen layer. The PDFs can be created directly from any PDF drawing software, or a PDF print driver can be used to capture the Print output if the drawing software does not directly support output to PDF.

The general workflow is as follows:

2. Print the top and bottom copper and top silk screen layers to a PDF file.
3. Run Pdf2Gerb on the PDFs to create Gerber and Excellon files.
4. Use a Gerber viewer to double-check the output against the original PCB design.
6. Submit the files to a PCB manufacturer.

Please note that Pdf2Gerb does NOT perform DRC (Design Rule Checks), as these will vary according to individual PCB manufacturer conventions and capabilities. Also note that Pdf2Gerb is not perfect, so the output files must always be checked before submitting them. As of version 1.6, Pdf2Gerb supports most PCB elements, such as round and square pads, round holes, traces, SMD pads, ground planes, no-fill areas, and panelization. However, because it interprets the graphical output of a Print function, there are limitations in what it can recognize (or there may be bugs).

See docs/Pdf2Gerb.pdf for install/setup, config, usage, and other info.

#To compensate for PDF rendering errors (either during CAD Print function or PDF parsing logic), adjust the values below as needed.

## Navigating Between DOM Nodes in JavaScript

In the previous chapters you've learnt how to select individual elements on a web page. But there are many occasions where you need to access a child, parent or ancestor element. See the JavaScript DOM nodes chapter to understand the logical relationships between the nodes in a DOM tree.

DOM node provides several properties and methods that allow you to navigate or traverse through the tree structure of the DOM and make changes very easily. In the following section we will learn how to navigate up, down, and sideways in the DOM tree using JavaScript.

## Accessing the Child Nodes

You can use the `firstChild` and `lastChild` properties of the DOM node to access the first and last direct child node of a node, respectively. If the node doesn't have any child element, it returns `null`.

#### Example

``````<div id="main">
<p id="hint"><span>This is some text.</span></p>
</div>

<script>
var main = document.getElementById("main");
console.log(main.firstChild.nodeName); // Prints: #text

var hint = document.getElementById("hint");
console.log(hint.firstChild.nodeName); // Prints: SPAN
</script>``````

Note: The `nodeName` is a read-only property that returns the name of the current node as a string. For example, it returns the tag name for element node, `#text` for text node, `#comment` for comment node, `#document` for document node, and so on.

If you notice the above example, the `nodeName` of the first-child node of the main DIV element returns #text instead of H1. Because, whitespace such as spaces, tabs, newlines, etc. are valid characters and they form #text nodes and become a part of the DOM tree. Therefore, since the `<div>` tag contains a newline before the `<h1>` tag, so it will create a #text node.

To avoid the issue with `firstChild` and `lastChild` returning #text or #comment nodes, you could alternatively use the `firstElementChild` and `lastElementChild` properties to return only the first and last element node, respectively. But, it will not work in IE 9 and earlier.

#### Example

``````<div id="main">
<p id="hint"><span>This is some text.</span></p>
</div>

<script>
var main = document.getElementById("main");
main.firstElementChild.style.color = "red";

var hint = document.getElementById("hint");
hint.firstElementChild.style.color = "blue";
</script>``````

Similarly, you can use the `childNodes` property to access all child nodes of a given element, where the first child node is assigned index 0. Here's an example:

#### Example

``````<div id="main">
<p id="hint"><span>This is some text.</span></p>
</div>

<script>
var main = document.getElementById("main");

// First check that the element has child nodes
if(main.hasChildNodes()) {
var nodes = main.childNodes;

// Loop through node list and display node name
for(var i = 0; i < nodes.length; i++) {
}
}
</script>``````

The `childNodes` returns all child nodes, including non-element nodes like text and comment nodes. To get a collection of only elements, use `children` property instead.

#### Example

``````<div id="main">
<p id="hint"><span>This is some text.</span></p>
</div>

<script>
var main = document.getElementById("main");

// First check that the element has child nodes
if(main.hasChildNodes()) {
var nodes = main.children;

// Loop through node list and display node name
for(var i = 0; i < nodes.length; i++) {
}
}
</script>``````

## How to Use Of Not Equal To The Operator in Bash

Many types of operators exist in Bash to check the equality or inequality of two strings or numbers. The “-ne” and “!=” operators are used to check the inequality of two values in Bash. The single third brackets ([ ]) are used in the “if” condition when the “!=” operator is used to check the inequality. The double third brackets ([[ ]]) are used in the “if” condition when the “-ne” operator is used to check the inequality. The methods of comparing the string and numeric values using these operators are shown in this tutorial.

## Using the “!=” Operator

The “!=” operator can be used to check the inequality between two numeric values or two string values. Two uses of this operator are shown in the following examples.

Example 1: Checking the Inequality Between Numbers
Create a Bash file with the following script that takes a number input and check whether the input value is equal to 10 or not using the “!=” operator. The single third brackets ([ ]) are used in the “if” condition here.

``````#!/bin/bash
#Take a number
echo -n "Enter a number:"

#Use '!=' operator to check the number value
if [ \$number != 10 ]; then
echo "The number is not equal to 10."
else
echo "The number is equal to 10."
fi``````

The script is executed twice in the following output. Twelve (12) is taken as input in the first execution and “The number is not equal to 10” is printed. Ten (10) is taken as input in the second execution and “The number is equal to 10” is printed:

Example 2:
Create a Bash file with the following script that takes two string values and check whether the input values are equal or not using the “!=” operator. The single third brackets ([ ]) are used in the “if” condition here.

``````#!/bin/bash
#Take a number
echo -n "Enter the first string value: "
echo -n "Enter the second string value: "

#Use '!=' operator to check the string values
if [ "\$str1" != "\$str2" ]; then
echo "The strings are not equal."
else
echo "The strings are equal."
fi``````

The script is executed twice in the following output. The “Hello” and “hello” string values are taken as inputs in the first execution and these values are not equal because the string values are compared case-sensitively. In the next execution, the “hello” and “hello” string values are taken as equal inputs:

## Using the “-ne” Operator

The “-ne” operator can be used to check the inequality between two numeric values but not can be used to compare the string values. Two uses of this operator to compare the numeric and string values are shown in the following examples.

Example 1:
Create a Bash file with the following script that takes the username as input. Next, the length of the input value is counted after removing the newline(\n) character. Whether the length of the username is equal to 8 or not is checked using the “-ne” operator. The double third brackets ([[ ]]) are used in the “if” condition here.

``````#!/bin/bash

#Remove newline from the input value
#Count the total character

#Use the '-ne' operator to check the number value
if [[ \$len -ne 8 ]]; then
echo "Username must be 8 characters long."
else
fi``````

The script is executed twice in the following output. The “admin” is taken as input in the first execution and the “Username must be 8 characters long” is printed. The “durjoy23” is taken as input in the second execution and the “Username: durjoy23” is printed:

Example 2:
Create a Bash file with the following script that takes the username as input. Next, whether the input value is equal to “admin” or not is checked using the “-ne” operator. The double third brackets ([[ ]]) are used in the “if” condition here. The “-ne” operator does not work to compare two string values.

``````#!/bin/bash

#Remove newline from the input value

#Use '-ne' operator to check the string values
echo "Invalid user."
else
echo "Valid user."
fi``````

The script is executed twice in the following output. The “if” condition is returned true in both executions for the valid and invalid outputs which is a “wrong” output:

## Conclusion

The method of comparing two values using the “!=” and “-ne” operators are shown in this tutorial using multiple examples to know the uses of these operators properly.

## Hands-on Guide to Pattern - A Python Tool for Effective Text Processing and Data Mining

Text Processing mainly requires Natural Language Processing( NLP), which is processing the data in a useful way so that the machine can understand the Human Language with the help of an application or product. Using NLP we can derive some information from the textual data such as sentiment, polarity, etc. which are useful in creating text processing based applications.

Python provides different open-source libraries or modules which are built on top of NLTK and helps in text processing using NLP functions. Different libraries have different functionalities that are used on data to gain meaningful results. One such Library is Pattern.

Pattern is an open-source python library and performs different NLP tasks. It is mostly used for text processing due to various functionalities it provides. Other than text processing Pattern is used for Data Mining i.e we can extract data from various sources such as Twitter, Google, etc. using the data mining functions provided by Pattern.

## Why Use WordPress? What Can You Do With WordPress?

Can you use WordPress for anything other than blogging? To your surprise, yes. WordPress is more than just a blogging tool, and it has helped thousands of websites and web applications to thrive. The use of WordPress powers around 40% of online projects, and today in our blog, we would visit some amazing uses of WordPress other than blogging.
What Is The Use Of WordPress?

WordPress is the most popular website platform in the world. It is the first choice of businesses that want to set a feature-rich and dynamic Content Management System. So, if you ask what WordPress is used for, the answer is – everything. It is a super-flexible, feature-rich and secure platform that offers everything to build unique websites and applications. Let’s start knowing them:

1. Multiple Websites Under A Single Installation
WordPress Multisite allows you to develop multiple sites from a single WordPress installation. You can download WordPress and start building websites you want to launch under a single server. Literally speaking, you can handle hundreds of sites from one single dashboard, which now needs applause.
It is a highly efficient platform that allows you to easily run several websites under the same login credentials. One of the best things about WordPress is the themes it has to offer. You can simply download them and plugin for various sites and save space on sites without losing their speed.

2. WordPress Social Network
WordPress can be used for high-end projects such as Social Media Network. If you don’t have the money and patience to hire a coder and invest months in building a feature-rich social media site, go for WordPress. It is one of the most amazing uses of WordPress. Its stunning CMS is unbeatable. And you can build sites as good as Facebook or Reddit etc. It can just make the process a lot easier.
To set up a social media network, you would have to download a WordPress Plugin called BuddyPress. It would allow you to connect a community page with ease and would provide all the necessary features of a community or social media. It has direct messaging, activity stream, user groups, extended profiles, and so much more. You just have to download and configure it.
If BuddyPress doesn’t meet all your needs, don’t give up on your dreams. You can try out WP Symposium or PeepSo. There are also several themes you can use to build a social network.

3. Create A Forum For Your Brand’s Community
Communities are very important for your business. They help you stay in constant connection with your users and consumers. And allow you to turn them into a loyal customer base. Meanwhile, there are many good technologies that can be used for building a community page – the good old WordPress is still the best.
It is the best community development technology. If you want to build your online community, you need to consider all the amazing features you get with WordPress. Plugins such as BB Press is an open-source, template-driven PHP/ MySQL forum software. It is very simple and doesn’t hamper the experience of the website.
Other tools such as wpFoRo and Asgaros Forum are equally good for creating a community blog. They are lightweight tools that are easy to manage and integrate with your WordPress site easily. However, there is only one tiny problem; you need to have some technical knowledge to build a WordPress Community blog page.

4. Shortcodes
Since we gave you a problem in the previous section, we would also give you a perfect solution for it. You might not know to code, but you have shortcodes. Shortcodes help you execute functions without having to code. It is an easy way to build an amazing website, add new features, customize plugins easily. They are short lines of code, and rather than memorizing multiple lines; you can have zero technical knowledge and start building a feature-rich website or application.
