Last Week in AI

Every week, my team at Invector Labs publishes a newsletter to track the most recent developments in AI research and technology. You can find this week’s issue below. You can sign up for it below. Please do so, our guys worked really hard on this:

Interpretability remains one of the biggest challenges of machine learning applications. The famous tradeoff between interpretability and accuracy tells us that highly effective AI models are notoriously hard to analyze and understand. Without understanding the behavior of AI models, how can we possibly audit them and troubleshoot them effectively. The challenge of interpretability is even larger in models that deal with highly unstructured data such as image classifiers.

This week, AI researchers from Google and OpenAI published a ground breaking method that attempts to improve the interpretability of deep neural networks for image classifications. Called activation atlases, the new technique allow us to understand how image classifiers build their internal knowledge. In other words, we can “see what the neural networks sees”. Even though activation atlases is still highly experimental, some of the concepts seem incredibly robust and promising. Certainly an important step towards improving the interpretability of deep learning models.

Now let’s take a look at the core developments in AI research and technology this week:
