Business Intelligence forms the back-bone of decision making in an ever-growing number of organisations in the world today. More than ever, organisations need to be able to make fast decisions to changes in the market. Unfortunately, many businesses do not have a system that allows them to obtain the insights they need to do this. […]
In this week’s data science project, I apply principal component analysis to a dataset based around hospital mortality using python. The dataset is extensive, containing over 50 variables on demographic characteristics, vital signs, and other measurements taken in the lab. This should be a perfect use-case for dimensionality reduction with PCA. What is Principal Component […]
In this data science project, I tackle the problem of data segmentation or clustering, specifically applied to customer data. There are a couple of different algorithms to choose from when clustering your data depending on your requirements and inputs. However, K-Means clustering is one of the most popular methods in machine learning and is the […]
Task automation has become like a secret weapon as a data scientist. My only regret is not getting started with automation sooner. In the past, I have felt intimidated by the process of automation because I always thought it was an intensive, tedious process. I have come to learn that automation has done the exact […]
Those companies that view data as a strategic asset and develop robust data and analytics strategies are the ones that will succeed in this new data-driven world. Bernard Marr It is very easy to get caught up in the latest buzzword, jumping on the big data bandwagon without any clear direction on where you would […]
It is quick and easy to start analysing Google Sheets data in Python using the EZSheets library. I typically write python scripts that automate the extraction and analysis of data stored in Google Drive. The best use case I have found for this is when using Google Forms. There are situations where you may be […]
The Python logging module has been part of my toolkit since the very beginning of my data science journey (thanks to a former colleague who helped me build my first web scraper and showed me some good practices to start with early rather than later). Now, whenever I create a python script (especially ones that […]
Power BI has been my go-to data visualisation and business intelligence tool for the last 3 years. I have built corporate dashboards with it and used it as my own little exploration tool when I’m tackling a new data set for the first time. Since I’ve been getting more and more proficient at using the […]
At what point do you get to declare “I am a data scientist”? How many PhD’s, decades of experience or deep learning models do you need to have under your belt before you feel like a ‘real’ data scientist? The truth is, data science is advancing so rapidly that it really is impossible to keep […]
If you have read my beginners guide to building a data science portfolio then you already know how important it is to find a way to demonstrate your skills, especially if you don’t have any work experience yet. The three most popular platforms for building a portfolio are Github, Kaggle and a personal website or blog. At […]
