5. Cleaning the data

**Introduction: **With the sharp rise of data, it is only going to get better to scrape, gather, collect, amass, and many other equally meaningful words of all sorts of information from multiple sources such as Facebook, Twitter, and Reddit. With that in mind, Reddit for so long has had an API called the Python Reddit API Wrapper, shortened for PRAW, using python (as already in the name I know!) to crawl data. …

2. Using TextBlob

3. Using local classifier

**Introduction:**A recent predicament I have crossed recently is the lack of suitable datasets or corpus to train your model on. Sometimes even when having sufficient data if it’s not labeled then it does little benefit. Usually, the go to solution for something like this is unsupervised learning in order to cluster or group them into classes, thus creating the dependent column one wishes for. …

4. Scrape Tweet Conversation

**Introduction:**For the most part, when anyone is anyone when thinking of data and scraping it, Twitter mostly if not always pops up to mind. If you’re reading this article I’m more than sure you don’t need me to tell how twitter is this huge treasure equivalent when it comes to raw data and so forth. Nor will I either bombard you with statistics (even though they are super exciting but nonetheless not today’s subject) or quotes from industry leaders on just that. …

When diving into supervised machine learning for the very first time, one usually interacts with logistic regression quite early on probably after learning about linear regression. And for good reason, that is, logistic regression whether it be binary or multinomial is very similar to linear regression. Logistic regression is used to predict the probability of any certain value belonging to either one of 2 categories or one of the multiple categories. So the biggest difference between linear and logistic regression is: Linear regression assumes the data is of linear variability, normality, and homoscedasticity. To put in simpler terms the data…

Linear Regression is probably the first algorithm you will encounter when starting out your Data Science learning journey — and guess what? So did I and most probably everyone else. It’s one of the least complex if not the actually least complex algorithm to understand and apply.

Now let’s start with math, I know this is not the fun part of Data Science overall but it is as important to grasp as anything else.

Let’s break down this equation into chunks one could bite:

4. Dynamic undersampling and oversampling

**Introduction: **One could easily find all the datasets, corpora, and so forth and so forth and most of them if not all of them are gonna be in pristine and perfect condition. No null values, balanced classes, large amounts of data, every data scientist's version of the perfect dataset. Alas, this is more or less is a rarity, almost what Egyptians would call a “4th impossible” one could say. Undersampling and oversampling are techniques used to combat the issue of unbalanced classes in a dataset. We sometimes do…

Data Engineer @ IBM, and hopefully a future full-stack Data Scientist. This blog is part of my learning journey, maybe it can be part of yours too.
