How to solve 90% of NLP problems: a step-by-step guide

-
Image
Text data is everywhere Whether you are an established company or working to launch a new service, you can always leverage text data to validate, improve, and expand the functionalities of your product. The science of extracting meaning and learning from text data is an active topic of research called Natural Language Processing (NLP). NLP produces new and exciting results on a daily basis and is a very large field. However, having worked with hundreds of companies, the Insight team has seen a few key practical applications come up much more frequently than any other: Identifying different cohorts of users/customers (e.g. predicting churn, lifetime value, product preferences) Accurately detecting and extracting different categories of feedback (positive and negative reviews/opinions, mentions of particular attributes such as clothing size/fit…) Classifying text according to intent (e.g. request for basic help, urgent problem) While many NLP papers and tutorials exist onlin...

Basics of Image Processing in Python

-
Image
Writing today’s article was a fascinating experience for me and would also be for the readers of this blog. What’s so different? Two things: firstly the article is about something I always wanted to do since I was a 5-year old; secondly this topic / tools / algorithm is new to me as well. I am no way a master of image processing, but the utility of this field simply blew my mind. Imagine, if you can create an application of auto-tagging a photograph as that of Facebook, or create your own face recognition password to your laptop. In this article, I will pick up a very simple but interesting application of Image processing. We will use Python to do the image processing.  In the next few articles, I will take over more complex examples of Image Processing. Here is the problem I will be working on in this article: Problem Statement Guess what is this image? You are right, it’s a typical picture of an open sky. I took this picture last to last night in Bangalore f...

Introduction to Libraries of NLP in Python — NLTK vs. spaCy

-
Image
The two significant libraries used in NLP are NLTK and spaCy. There are substantial differences between them, which are as follows: NLTK provides a plethora of algorithms to choose from for a particular problem which is a boon for a researcher but a bane for a developer. Whereas, spaCy keeps the best algorithm for a problem in its toolkit and keep it updated as state of the art improves. NLTK supports various languages whereas spaCy have statistical models for 7 languages (English, German, Spanish, French, Portuguese, Italian, and Dutch). It also supports named entities for multi-language. NLTK is a string processing library. It takes strings as input and returns strings or lists of strings as output. Whereas, spaCy uses an object-oriented approach. When we parse a text, spaCy returns document object whose words and sentences are objects themselves. spaCy has support for word vectors whereas NLTK does not. As spaCy uses the latest and best algorithms, its performance is usually...

If you’re like most Internet users, you download various types of files now and then. You either download these files with your web browser or some download manager software. Have you ever considered downloading files using the command prompt i.e. CMD? If not, we recommend you to try it. It’s quite interesting apart from being very useful as well. In this article, we’ll show you how to download a file using command prompt aka CMD. How to download a file using command prompt?   There are several useful commands for the Command Prompt and one of them is  bitsadmin . Though bitsadmin has several uses, here we shall limit this article to its role in downloading files only. If you want to read the details about bitsadmin syntax, continue reading this section. Otherwise, you can scroll down to the next section –  Downloading a file .   The syntax of bitsadmin is : BITSADMIN [/RAWRETURN] [/WRAP | /NOWRAP] command   As you know, the parts of the syntax inside ...

The future of Artificial Intelligence: 6 ways it will impact everyday life

Technology moves at breakneck speed, and we now have more power in our pockets than we had in our homes in the 1990s. Artificial intelligence (AI) has been a fascinating concept of science fiction for decades, but many researchers think we’re finally getting close to making AI a reality.  NPR notes that in the last few years, scientists have made breakthroughs in “machine learning,” using neural networks, which mimic the processes of real neurons. This is a type of “deep learning” that allows machines to process information for themselves on a very sophisticated level, allowing them to perform complex functions like facial recognition. Big data is speeding up the AI development process, and we may be seeing more integration of AI technology in our everyday lives relatively soon. While much of this technology is still fairly rudimentary at the moment, we can expect sophisticated AI to one day significantly impact our everyday lives. Here are 6 ways AI might affect us in the ...

HOW TO INCLUDE three.js IN YOUR PROJECTS There are quite a few different ways to include three.js in your JavaScript application, some of them simple, some of them a little more complex, however, they all boil down to one simple idea: you need to include one (and  only one) of these three files in your project: three.js three.min.js three.module.js You can view them all  on the three.js GitHub repo , which we’ll explore in the next chapter. Each of these files a version of the three.js core, meaning that once you’ve included one of them in your application, you are all ready to get started in creating beautiful 3D scenes. There are two main ways to include these files in your project: include them in a  script tag  in your HTML import them directly into your JavaScript files. We’ll explore how to do in Section Two What’s the Difference Between these Files? The  three.js  file is intended to be included in a  <script> ...
