I find this completely false, messaging anyone on a non-iPhone (from my iPhone) is a complete disaster. Pictures / texts randomly fail to send, videos turn to 12 pixel noise, it’s so bad that an entire generation of people have friend

Chess can get like this to an extreme extent. Sometimes when playing chess with friends I'll make an obviously un-optimal move because it has a chance at putting the game in a weird situation. Just something _different_ for a change is

Some implementations will group the categories into two groups, right and left. An easy way to do this is to create the groups based on whatever grouping creates the biggest decrease in the loss. There are more complicated implementations,

I have a theory - tree based models require minimal feature engineering. They are capable of handling categorical data in principled ways, they can handle the most skewed/multimodal/heteroskedastic continuous numeric data just as

Wow, very interesting, thanks for this. Daily batch predictions is all we do. I’m the maintainer of miceforest[1], do you think this would integrate well into the package at a brief glance? I’m always looking for ways to make this package f

I think it really depends on your data size. All the benchmarks I can find are on massive datasets, with tens of millions of rows or thousands of columns. I’m sure there are significant performance gains in these situations. Our data just w

All kinds of speculative assets exist solely to hedge and make money on. The algorithmic traders on Wall Street aren’t trading soybeans futures because they can eat them. They’re making money. If people see price fluctuations in anything, a

Soybeans (and most other assets) have inherent value which gives them a price minimum, but not necessarily a price maximum. Crypto has no price minimum (0 I guess, at which point returns are incalculable) and no price maximum because it has

I understand that some catastrophe or economic collapse could cause all of that, but I don’t think it’s a necessity for unemployment to skyrocket if house prices dip 20%. Also what makes you think any of this is connected to crypto?

by CapmCrackaWaka 4y ago
The physicality of an underlying asset isn’t what makes people trade stocks, commodities, options or anything else. If you’re day trading soybean futures, it’s not the ideal of soybeans that wakes you up in the morning. It’s the money you c

I’m skeptical that prices are going to fall too much. Go to any Reddit thread on the topic of interest rates, talk to any of your young friends that haven’t bought a house yet, and you’ll find a common theme. “I can’t wait for house prices

That's funny, I went the opposite direction. I only use pandas if I need to group by and aggregate, or to use in plotting functions. When doing array operations, I pretty much always use numpy, figuring out how to broadcast and vectori

I have seen many “plots” of prime numbers that look really good. In addition to looking good, I sometimes _swear_ I see a pattern. It’s really frustrating, to see something on a graph which looks like it follows some pattern or algorithm[1]

Surely speculation about the rise in interest rates has been taken into account by the market, though? If I expected stocks to decrease _drastically_ in the future as the fed increases rates, I would just sell right now, maybe even hold a s

I still cannot believe people shave with Gillette razors, or any other of those fancy multi-blade razors. I paid $10 for a pack of 100 double sided razor blades 3 YEARS ago and I’m still not even close to finished with the pack.

Agreed, I never watch TV unless it's, weirdly enough, a social setting. My wife and I watch TV together all the time, we have shows that we like to enjoy together and talk about. My roommates and I would watch TV together all the time

Interesting to see where different peoples values lie. Living life like this sounds absolutely miserable to me, no matter how much money I would bring in. But hey I understand that some people enjoy the hustle.

It's interesting to see the cyclical rise and fall of workers unions in the US. I'm of the opinion that there needs to be a balance between worker and employer rights - however it seems that, at least in the US, that balance swing

Feature selection is a process by which you drop features for different reasons. The main reason features tend to be dropped is because they are closely related to another feature, so you only need one of them. This makes algorithms train f
