On Monday, when I had a doctor’s appointment, I unexpectedly had a conversation with my doctor about the uses of AI in hospitals — specifically pertaining to electrocardiograms. As someone who has used ECG’s many times in their life, I found this conversation very interesting. While this was only mentioned briefly in passing, I went home and decided to look further into this Artificial intelligence in ECG diagnostics – where are we now?.
This week I had a group tutorial session to start the week. We had a discussion on different key terms in relation to machine learning and I was surprised with how much I knew. I was also pleasantly surprised with the fact that many people were struggling with the same things that I was.
While going through my machine learning project, I tested with the epochs, batch size and learning rate. Afterwards, the loss value didn’t improve, and on some occasions during testing it reached 80,000! Confused by this, I found an article Interpretation of Loss and Accuracy for a Machine Learning Model | Baeldung on Computer Science. I noticed that regardless of my loss value, my accuracy stayed extremely low! After some reading I realised that this is because the likelyhood of my correct predictions is not super low, however, incorrect predictions are higher
Later on, Max Elkins gave a talk about how he works as a developer and designer. He showed some demos that he made simply with HTML and CSS. I was really interested in how he uses the minmax function to make sure that each grid that he was working with displayed nicely on his website. position-area and how he used it to display a popup menu (paired with position-try-fallbacks) was something that I have never heard of, but was suprised when it didn’t require any javascript!
He mentioned this concept of relative colour, LCH and how it make sure contrast in websites remain the same despite different hues. I’ve heard of RGB and hex values, but never this. By using LCH, you can keep the saturation and brightness of the colours the same to make sure that important information can stand our well, regardless of the colour. This is something subtle, but will be something I remember for benefitting user experience if I have any important information I need to display.
I had my first look at arduino this week! I found it a bit confusing to be honest, but the code itself isn’t too hard. It took me a bit to understand where to put resistors in relation to my led and wires, but once I got it done I was glad. Once I heard that we can use the arduinos for many things (hooking them up to speakers, and LCD screens I was really fascinated, its amazing how such a small piece of hardware can work with code and external components.
