I'm experimenting with open research notes now I'm a free agent. I thought this might be a fun project to share, because it ended up being a small metaphor for every ML project I've ever done. Not a serious software project,

Yes, my experience has been that it is great if you need to do something particularly weird, but less smooth to do something ordinary.

I'm sure there is a way of interpreting a relu as a sparsity prior on the layer.

It is fun if you ever find yourself in this situation because you can play the uno reverse card on the interviewer and ask to clarify with impenetrable jargon and look for rising panic (can I assume the graph contains a Hamiltonian circuit

The error budget in the pseudorange to the satellites has various factors due to relativity, but they are just lumped into the errors in the least squares problem that you solve to get the position estimate (as per the article). So relati

Whooping cough does not come from pigs. Pertussis is a bacterium that is a human only thing.

Basically kernel methods right?

I'd say a fairly large percentage would be disappointed that we let a citizen get treated like that and we did nothing as a country to assist, independent of anything else. Maybe I am out of touch though.

Here in Australia the coldest state (tas) uses more energy (8600) than anywhere else (e.g. qld 5500). They have basically 100% hydro power and use reverse cycle AC for heating. Not sure what else is going on there.

You can look at a medieval bestiary to see how people thought animals might look based on descriptions alone. Like these lovely elephants https://britishlibrary.typepad.co.uk/digitisedmanuscripts/20...

I'd say it's not new. Take fluid dynamics as an example, the navier stokes equations predict the motion of fluids very well but you need to approximately solve them on a computer in order to get useful predictions for most setups.

It seems like a good application of the technology to a real problem, it just sucks so much that the meta problem is so diabolical. Definitely a local optimisation far from the global.

The whole process comes from a time when publishing was expensive, should be cheap as chips now. The system needs a rethink so "quality" can somehow bubble up to the surface given mass publication is so simple.

The biggest one I have run into is that the bandwith doesn't need to be contiguous. If you know the the important bits of the signal are contained in certain frequency bands then you can get much lower sampling rates. Basically why thi

It's not that long ago in human history that basically none of the jobs we do now existed. So it is kind of myopic to think that any current career is a calling. Art can become a craft again, not a career. There is nothing wrong with t

Because fuel cells are very efficient at turning fuel to electricity, especially compared to an ICE.

That is also what statistical modelling feels like. EDA and data cleaning.

Just for a bit of background, transmission companies want to know the temperature of transmission lines because the dynamic clearance of the line to the ground as the current heats the wire limits the max current. Surprisingly complex to mo

They are often surprisingly ruthless when given cost as part of the objective as well.

I was also incredibly optimistic about this approach in the past but life experience has shifted me away from it. I personally can't understand people not wanting to know. It is weird dynamic. I changed jobs a few years ago and went fr

It's just correlation, why do they keep calling it autocorrelation.

A gaussian mixture is a universal density approximator, so you can definitely approximate a lognormal with such a model.

My understanding (that might be out of date) is that the tools are weak. Ideally you would have tabular data and it would give you a digraph for the causal structure between variables. You can try this but the tools don't work reliably
