TGIF. Meme

First of all, let's check the results of the poll. One subscriber promised to unsubscribe, and the other 9 voted for memes and shitposting. A naive approach would be to think that if I publish the meme, I'll lose 1 subscriber. But you can solve the proportion, and it gives -27.6 subscribers. The result is stunning, so, let's see. I expect to drop to 248.4 subscribers.

The topic of today's Friday meme is The Soup.

First of all. I stole these memes from The Wizard . I think that it is a magnificent channel and I ask you to promote it as widely as you can.

And now to the chase.

Dad's soup

My dad cooks absolutely hellish food.
It’s a sort of averaged recipe, because there are lots of variations.
He takes soup — but reheating it is not my dad’s style.
He pours the soup into a frying pan and starts frying it.
He adds a huge amount of onion, garlic, tomato paste, flour for thickness, and mayonnaise on top.
The whole thing fries until smoke starts coming out.
Then he takes it off the heat, lets it cool on the balcony, brings it back, pours on even more mayonnaise, and starts eating.
He eats straight from the pan, scraping it with a spoon, muttering under his breath, “oh, damn.”
Sweat is standing on his forehead.
Sometimes he politely offers me some, but I refuse.
Needless to say, the aftermath is monstrous.
The stench is so intense that the wallpaper peels off the walls.


P.S. To be honest, all this subscribe/unsubscribe stuff is starting to get to me. I’d really appreciate some support — even a couple of emojis wouldn’t hurt.

P.P.S. Tomorrow I’ll try to pull myself together and write something clever. Probably continue the “Titanic” line.

Titanic: family bonds

Nowadays, it is hard to imagine an ML person without a Jupyter notebook. So let’s think a little outside the box and consider other options.

Quite recently, I discovered an interesting option for CSV table analysis. It consists of two instruments: DBeaver and DuckDB. The former is a Swiss army knife for database access, and the latter is a plugin that is quite powerful, or so I was told, but can also be used to open CSV files.

So, you can create a new DuckDB connection in DBeaver (ducks and beavers, yeah...), select the titanic.csv file you got from Kaggle, and start running queries.

SibSp is a factor, so to speak, horizontal in the ancestry tree. It is the sum of siblings and spouses. Parch is vertical in these coordinates: parents and children.

The first two queries show us the strength of these factors separately. The third uses the nested query technique to produce a derived factor, family size. One can see that these factors are useful, but the derived factor gives a stronger depletion/enrichment effect. This time, we were lucky enough to engineer a new feature.

I would say that family sizes 2, 3, and 4 vote for survival; the others vote against it.
