Welcome to Candid Machine Learning Conversations. I’m Ryan Louie, and I interview machine learning practitioners about their thoughtfulness behind their profession.

Computational Thinking with Reddit at the Wolfram Summer School

By swede white — Reading: 8 min.

Around this time last year, I was trying to figure out what to do with my summer. It had been a rather hellacious semester in graduate school, but I was finally done with core coursework in my doctoral program in sociology at Louisiana State University.

Backward Propagation for Feed Forward Networks

By SauceCat— Reading: 7 min.

To train the networks, a specific error function is used to measure the model performance. The goal is to minimize the error(cost) by updating the corresponding model parameters. To know which direction and how much to update the parameters, their derivatives w.r.t the error function must be calculated. And this is what backward propagation is used for.

Tracking pedestrians for self driving cars

By Priya Dwivedi — Reading: 5 min.

A self driving car needs a map of the world around it as it drives. It must be able to track pedestrians, cars, bikes and other moving objects on the road continuously. In this article I will talk through a technique called Extended Kalman Filter which is being used by Google self driving car to track moving objects on the road.
