I’d love the thank my friends who gave me permission to use their handsome faces in the name of artificial intelligence science!
We can definitely tell that this fine gentleman has brown eyes. On the other hand, the model is pretty certain that this individual has blue eyes with a probability greater than 90%. What’s going on here? Let’s try another example…
In the previous newsletter, before my declared absence, we talked about what is an algorithm. We ended by having the problem of grading diabetic retinal images — a task that is not as easy as sorting people’s names!
Grading retinal images for diabetic retinopathy (DR) is an image classification problem. We have images, and we need to grade them into these possible categories: healthy, background DR referrable DR.
Why is this useful?
In Aotearoa, 250,000 people have diabetes and a quarter have DR. Fortunately, individuals with diabetes are screened with routine retinal imaging taken at least biennially. But, unfortunately, that’s…
Over the last few months, I’ve been working on writing an article about artificial intelligence and eye care.
To begin this journey is learning about this topic. We need to understand what are algorithms.
An algorithm is what computers use to solve problems, taking input and provide the desired output.
Here is an example. We have a list of names that we need to sort alphabetically. We could do this by hand, but let’s leverage the power of computing to solve this problem for us instead. …
I’ve had this article topic for a while now and what sparked me to write it was the tweet from one of my idols below:
If I’ve got computer A in one room and computer B in another room, both on the same network.
What’s the best way to execute code written on computer A on computer B?
If anyone’s written a guide or got one handy, I’d love to know.

I also had the problem of showcasing my work. Daniel Bourke is a strong proponent of showing one’s work. The dilemma…
I’m frantically writing this one 10 minutes before the usual self-imposed deadline of 10 AM Sunday (NZT). Let’s see if I’ll make it?
This week a friend asked my underlying reason for blogging. To extend that further, why do I have an active presence on LinkedIn? Why do I publish content online? To answer this question, I want to refer to my first ever blog post.
Posted over a year ago, I’m happy to say that I have remained consistent — especially with this newsletter.
Posted over a year ago, the why of blogging, putting stuff out there, still stands…
Are we rich? We probably are, but we think otherwise. So is our lack of having really true?
Thinking we don’t have enough money is a big barrier to giving. It’s also a stop against happiness.
Our ‘richness’ is derived from social comparison to those around us. “Keeping up the with the Jones’s”. In New Zealand, we are likely surrounded by others who are well off. This creates the idea that what we have isn’t enough.
When we think we’re just getting by (with a full belly and a roof over our…
In recent weeks, I had two conversations about the same topic. One was in front of an audience. The other was with a friend.
The topic: flow.
But what is the flow? Flow is the optimal state of mind. The task at hand is effortless. You are in the zone. Nothing matters but what is in front of you. Time dilates. Hunger doesn’t stop you. The state is addicting.
This is where you do your best work, your most satisfying work. The pinnacle of human productivity is achieving and sustaining the flow state.
Big companies try and achieve this. The…
Before I answer, let me share a brief history of my upbringing, which led me to write this newsletter. When I was young (and still am), my parents loved me as most parents do. They loved me so much that they gave me everything in the world. To add icing to the cake, I am an only child too. So I get all that love and attention.
Lucky me. But because I didn’t have to suffer, does this hinder my ability to be considerate towards others? Do I have difficulty connecting with others through their pain and suffering? …
…to the average person, if you go to a funeral, you’re better off in the casket than doing the eulogy.

The fear of looking stupid definitely crossed my mind. In the past, I really had to scrape the barrel for any motivation to speak in front of others. In fact, one example where it went horribly and embarrassingly wrong is my studentship presentation I had in my fourth year of University.
Without getting into too much detail, I was ripped apart by the head of department in front of all my peers. It was so bad, I…
WARNING: some of linked content is graphic.
The YouTube algorithm** got me hooked. I’ve been diving deep into criminal psychology. That’s thanks to this YouTube channel: https://www.youtube.com/channel/UCYwVxWpjeKFWwu8TML-Te9A.
The video that led me down this rabbit hole:
Crime aside (not because the act isn’t important, but it’s rather gruesome, and I want to spare you the detail), I want to focus more on the psychological aspect of criminology. For example, in this video, we can see how someone acts crazy but is fully attentive to their devious actions. The suspect appeals to a case of insanity in hopes of reducing…
