Natural Language Processing Notes

Introduction

Whenever we build Machine Learning models, we need some form of metric to measure the goodness of the model. Bear in mind that the “goodness” of the model could have multiple interpretations, but generally when we speak of it in a Machine Learning context we are talking of the measure of a model's performance on new instances that weren’t a part of the training data.

Determining whether the model being used for a specific task is successful depends on 2 key factors:

1. Whether the evaluation metric we have selected is the correct one for our problem
2. If we are following…

It’s highly unlikely that business owners are going to read this and begin to change their perspectives on how we define Data Science. Not because I doubt my influence or anything, but since I’m aware that the majority of my readers are at the beginning of their Data Science journey — I really dislike the term “aspiring” — but here is what I wish to tell you all…

Stop trying to be good at everything in Data Science, and pick 1 (max 2) area’s you want to specialize in and get really good at it!

Let’s face it... Breaking into…

Introduction

Deep Learning; The solution to the problems of mankind. Over the past few years, Deep Learning has advanced humanity in novel ways. One of these beneficiaries is the entire field of Natural Language Processing (NLP). But before we get into how, let’s explore the field of Deep Learning.

I’m pretty sure we’ve all seen the Venn diagram that illustrates the relationship of Artificial Intelligence (AI) to Machine Learning (ML) to deep learning. If not, it simply demonstrates that Deep Learning is a subfield of Machine Learning which is a subfield of Artificial Intelligence.

How Deep Learning differs from Machine Learning…

Books are truly my lifeblood; I’d consider myself an avid book worm, but I must retract that statement whenever it comes to technical books. For some strange reason, technical books always make me feel more sleepy rather than interested.

However, in the past, I’ve managed to conjure up the strength to keep my eyelids open and get through these books. Something I’ve realized is that whenever I have done that, I’ve made massive progress in the subject or area I’m studying, hence this month I’ll be doing it again.

For those that are interested in following what books I am…

Artificial Intelligence is rapidly creeping into the workflow of many businesses across various industries and functions. Due to advancements in Natural Language Processing (NLP), Natural Language Understanding (NLU), and Machine Learning (ML), humans are now able to develop technologies that are capable of imitating human-like interactions which include recognizing speech, as well as text.

In this article, we are going to build a Chatbot using NLP and Neural Networks in Python.

The Data

Before we can begin to think of any coding, we need to set up an intents JSON file that defines certain intentions that could occur during the interactions with…

Introduction

I’m sure we’ve all been in a position where we’ve tried to contact our bank, but before we can speak to an assistant, we have to go through some sort of automated system. How annoying is it when these systems simply can’t understand us? After minutes of back and forths and struggling to understand the system refers us to a real person to handle our query and take us through the exact same process.

It’s frustrating!

If we are going to be having conversations with a computer, we’d at least want for it to replicate a human interaction as much…

I don’t know where I’d be right now if it wasn’t for Youtube tutorials — I literally use them for everything, i.e. Improving communication skills, learning how to do new calisthenics tricks, how to get more matches on Tinder, and many other things.

There are some special channels that have helped me immensely in my Data Science development and I believe it’s important I share them with you. Brace Yourself.

Natural Language Processing Notes

Natural language processing (NLP) is a subfield of linguistics, computer science, and artificial intelligence concerned with the interactions between computers and human language, in particular how to program computers to process and analyze large amounts of natural language data [Source: Wikipedia].

If you’ve decided that NLP is the subfield of Data Science you wish to specialize your skills in, the next step is identifying the key areas you need to understand to progress your career. …
