Stay tuned! We're working on improving phrase matching as we speak. As for the Control-F thing... stay tuned on that too :)

Yep. We normalize our features as part of training, and the stdevs of each feature are part of the resulting model, along with the weights. (The means are always 0 because of the way we construct our training set.) The weights we use in pro

That would be ideal, but a lot of people are uncomfortable doing that, and you would not get critical feedback as often or as reliably.

You're right, it is begging the question, for any simple function, you basically have to tell it what all the derivatives are for it to work. The power of this technique is that it handles the product rule and chain rule for you, so co

You're right, there's only O(n) information in these particular n x n matrices, so you can multiply them in O(n^2). The code provided memoizes cell values using the key (r - c), so only O(n^2) work is required to read off the top

Thanks! What's your research on?

Yeah, I failed there. The whole article started out jokey but I ended up cramming a bunch more "serious" analysis in.

Really appreciate the feedback, comes with the territory :) I added an update to the article looking at what happens when you vary the average car length (corresponding to the % of trucks on the road), fwiw.

FWIW I tried this out, seeing what happens when there are varying average car lengths on the road. http://jliszka.github.io/assets/img/traffic/speed-vs-occupan... http://localhost:4000/assets&

OP here. That's a really good point. I just think the original article overreached in saying that zipper merging is a "simple cure" for traffic jams, without taking into account that the road might at or near capacity (and yo

OP here, excellent point. Since so much is determined by occupancy (cars per km), I think the only way to switch domains is to lower the road's occupancy, which is exactly what you're doing when you leave extra space in front of y

That was a joke ;) Onramp regulators are the real answer, letting only 1 car merge into traffic at a time at a rate well under 1 every 2 seconds.
