Julian's Notes

Anyone who has followed Nigerian music over the years can acknowledge it has come a long way. Once there was a time I didn’t fancy much of the jams our artists put out. I would label them as too loud or too fast, with inordinately shitty lyrics. But times have changed. I guess the current […]

The first note in this series gave an introduction to the K- Nearest Neighbour algorithm. In the note, I went ahead to point out some of the concerns around KNN. I also did a primer on concepts like Feature Scaling and Euclidean distances. In this note, we will be implementing a simple movie recommender system […]

Much of Machine Learning involves finding and exploring patterns in data. ML algorithms will typically learn patterns from training data and apply what is learned on new data. One algorithm deviates slightly from this method, however; instead choosing to discover patterns as it encounters new data. K Nearest Neighbours (KNN for short) is an algorithm […]

Throughout last week, I was unable to shake off an overarching feeling of dread. Usually, I’m not one to allow external circumstances to influence my mood. Life is hard. Shit happens. You can’t take many things to heart. But if you’re a Nigerian like me, then you probably followed the recent protests against police brutality […]

Java developers will agree that Java 8 felt like a huge paradigm shift from Java 7. Java 8 was released in March 2014, and most notably introduced functional programming concepts, lambdas, and the Streaming API. Functional Programming in Java was a huge win for a language that already had a reputation for being too imperative.  […]

About a few weeks ago, I was mindlessly scrolling twitter when I stumbled on a tweet by Vala Afshar. In the tweet, he mentioned that google came into operation in the late 90s, at a time when there were several search engines already in the market. The tweet also included a nostalgic video clip of […]

Although it’s very possible to code a typical Machine Learning algorithm from scratch, most times we wouldn’t want to do that. The reason is that there are already a bunch of libraries that have been built to solve the common problems you will encounter in the course of implementation. Hence, in practice, it’s always best […]

Modern frontend development has really gone far. Honestly, if you can remember the early days, you know we’ve come a long way from relying on spaghetti JQuery code to deliver functionality to users. Today we have frameworks like React, Vue, and Angular. These frameworks encapsulate the MVVM and MVC software architecture patterns that make it […]

The most basic form of machine learning you can do is a Simple Linear Regression. Remember in an earlier post, I mentioned that Supervised Learning is a form of machine learning in which we utilize training data to teach our algorithm to derive a function that can make predictions on new data. SLR is a […]

As technology has evolved over the years, countless systems have sprung up into existence; each system formed on the basis of the intelligent application of knowledge and design principles. In our line of work, we design and build systems that provide services to our fellow humans. Think of all the great services we enjoy today: […]
