Have you been taught to use R for data analysis your whole career and wish to make the switch to Python? Are you thinking of applying for a new job which will make use of Python’s famous Pandas library and don’t have the know-how? While knowing how to code and manipulate data in R is very important, having the same level of expertise in Pandas is proving to be an invaluable skill for a data scientist in today’s world. …


For my end of phase project in the Flatiron School Data Science bootcamp, I was tasked to select a dataset of my own and build a machine learning classifier. This being my first project where I get to choose the data myself, I wanted to find a dataset that not only fits the classification problem at hand, but also something that I’d genuinely enjoy working with. After scouring the web for this dataset, I finally found the one: The Spotify Hit Predictor Dataset (1960–2019).

The Data

This dataset has information on a vast selection of songs from the 1960s all the…


As an aspiring data scientist, I often find myself getting really invested in the new material I’m learning and get excited at the fact that I’m inching closer and closer into the popular and revolutionary field of machine learning.

And while I don’t plan on contributing at all in the creation of a highly intelligent, autonomous killer cyborg, the idea of developing and training complex models to make our everyday lives easier is very appealing. However, as advanced and sophisticated as these models may be, they’re pretty much considered garbage if one crucial step is not taken…

DATA CLEANING

In order…


Have you ever been in a situation where you thought you knew something pretty well and then realised you were just barely scratching the surface? Or perhaps you already even developed an opinion and took a stance on an issue only to be disproven later on? While it’s completely understandable and expected to feel frustrated, with many doubts, and perhaps downright hopeless, these events should remind us to keep diving deeper, learn, and have an open mind — a common experience for many data scientists in today’s world.

Background

For my Phase 1 Data Science project at the Flatiron School…
