In recent years, convolutional neural networks (CNNs) have shown promising results for applications in computer-aided diagnostics. Despite their success, CNNs are constrained by the amount of data required to train them. Deep CNNs rely on large datasets, and although data augmentation techniques can be applied when sufficiently large datasets are…


In Introducing the pervert’s dilemma, Carl Öhman proposes a mode of philosophical inquiry to solve, at least partially, what he calls the pervert’s dilemma. This problem focuses on the seemingly contradictory moral intuitions we have about sexual fantasies and Deepfake pornography as a society. The dilemma is framed as follows…


This commentary will focus on the debate between Hatherley and Ferrario at al., where they discuss the topic of trust in medical AI. In Limits of trust in medical AI, Hatherley presents his concerns for the potential deficit of trust in clinical relationships with the displacement of epistemic authority of…


This post discusses some of the issues surrounding opacity in AI. In particular, I discuss: Is AI opaque in a way that other technologies are not? Should we aspire to or enforce some degree of transparency? …


One way to learn about machine learning is to simply play around with some models. Libraries such as scikit-learn are packed with tons of pre-built models that you can instantiate, fit and begin predicting within a few lines of code. …


This post builds off of material presented by Andrew Chamberlain in his article “The Linear Algebra View of Least-Squares Regression”. He does an excellent job of presenting linear regression within a linear algebraic model, and here I attempt to fill in some of the missing gaps that I encountered when…


In this tutorial, we’ll go through how to implement a simple linear regression model using a least squares approach to fit the data. After that, we’ll extend the model to a polynomial regression model in order to capture more complex signals. We’ll be using the mean squared error to measure…
