Electronic Tongues

I do this lab with my advanced biology class called "The Mystery Milk" lab. I give them 4 unknown liquids and they have to use a series of indicators to figure out what these milk-like products are. The students always ask me if they can taste the products (Answer: No, it's a science lab). But…

Neural Networks, Genetic Algorithms

Mimicking Biology Neural networks and genetic algorithms are a type of machine learning that mimics biological systems. Like the name suggests, the way neural networks work is similar to how the nervous system works. Same thing with genetic algorithms, they mimic how genomes evolve over time. Neural Network Nodes make up the different layers of…

Machine Learning 101

Follow the White Rabbit The field of artificial intelligence and machine learning has exploded in the last decade. And thanks to The Matrix and Keanu Reeves, it's all a bit scary and sexy. In this post, I'll talk about some basic concepts of machine learning. Like with kids, there are different "learning styles"; in the…
