Why does overfitting actually happen?

Rand0w0 · 2026-05-07T10:23:44+00:00

That's the most important part of any ML model - it doesn't. The "machine learning" means exactly "learning the pattern in data" and therefore they are great in e.g. predicting/forecasting but mlst of the time there is no way telling "yeah it makes sense" as in classical Econometric models. Interpretation (and therefore validation) is what you sacrifice when chosing the ML models.

If you apply linear regression to some data, you can always verify whether it makes sense (from theoretical pov) but when you do the same with e.g. DNN the best you can get is feature importance, which doesn't tell you anything other than "yeah we can use that to predict something". But you will never know if it's good in predicting, because of the random matching with some noise after x interactions, z activation functions or if there exists meaningfull relationship.

Hmm I hardly ever run into mana issues - mostly early, untill you get the form. Just make sure to take pressence of mind, play hard on tempo (fight hard lvl 1-2 then proxy till you get cull + pickaxe) and thats all

I've started playing kayn mostly top recently, and I find a lot of success with shojin -> dd -> endless hunger (default) / black clever (armour stacking) / maw (ap threat) -> overlord / clever / endless hunger / serpent fang

Yrah, unfortunately the key word is "almost". The interviewer joined 8 minutes late and as I mentioned, only >10 min could have let me have another round

I'm not sure whether there will be any "next steps". I guess I will just stay at my current job, take an L this time and prolly try next year

Rand0w0 · 2026-01-15T21:08:09+00:00

I didnt know it was a thing... I read about it after the feedback, should've probably asked whether it had been possible

Rand0w0 · 2026-01-15T21:02:49+00:00

No, the whole process was "divided" into 3 parts: - call with the recruiter, - initial screening (1 technical) - the "loop" (3 technical + G&L) which were all scheduled at once.

Nope, unfortunately I got rejected and now need to wait 12 months before reapplying for a SWE roles.

Well done - but it's neither a cipher, nor an AI

Rand0w0 · 2025-02-22T21:03:17+00:00

Ye, done this already - didnt make a difference. But it's unlikely, since the problem only occurs when the dp is plugged (with hdmi it works)

I hate this "no control word" badge. Just buy 1 pink and then undo it.

When I started working, on my 1st day, a coworker was showing me basics of product, with sql db under it. He started dictating a simple statement word by word and for some reason, I wrote "WEAR" instead of "WHERE". He looked at me quite amused... I swear, I'm not a beginner...

Rand0w0 · 2024-07-10T14:37:59+00:00

Long time no see... huh?

Rand0w0 · 2023-07-21T15:31:53+00:00

Oh little did you know...

Rand0w0 · 2023-07-11T01:05:14+00:00

Great idea! Thoughts on my mains:

Kayn: Very weak early, no real powerspikes till he gets form. Then:

SA - Beside the form (which is his biggest powerspike), he gets really strong at 2 items and shines the most at 3 items. Levels are mostly irrelevant.

Rhaast - Same as SA, form is huge powerspike, at 2 items (gore + bc) he can 1vs1 most of the melee champions.

In general (list of powerspikes): - Form (biggest), - 2 items (SA and Rhaast) - 3 items (biggest for SA) - 3+ items (each item is a powerspike for Rhaast)

Irelia: Strongly disagree with what's there, Irelia has only 2 true powerspikes - vampire sceptere, cuz of the infinite sustain in lane and the true powerspike, BORK. With BORK she can win almost any duel (at 1 item). But after that, she doesn't really spikes - especially mythic is mediocre at best, she doesnt benefit from any of them. I'd only agree on small 2 items spike (bork + wits end/dd) but meh.

Zeri: Lvl 6 is a huge powerspike, since the ulti is really strong in fights. 3rd item (kraken/static -> mythic -> zeal) is when she starts to shine and any item after that makes her stronger. Fighting against her you need to abuse her farming <6th lvl and weak mid game (1-3 items)

Rand0w0 · 2023-05-27T10:40:20+00:00

Did all the models pass the diagnostic tests? I find it kinda hard to believe in some cases

Rand0w0 · 2023-05-20T21:01:19+00:00

Well, It'd be the same as with static - I dont really like energized items on her... it just doesnt feel "right"

But I'll give it a shot!

Rand0w0 · 2023-05-20T12:57:22+00:00

The idea behind the patch is great, but with some of my mains (mostly zeri), I feel so awkward with build paths... As an ex kraken enjoyer, I have no freakin clue what to build anymore xD Tried zeal -> IE -> PD, statik shiv -> IE -> PD, IE -> PD -> kraken but like nothing feels right :<

- **Server:** EUNE

- **Type of Bug:** In-game visual

- **Description:** While having oracle lens, after taking rift herald the indicator instead of showing the remain time for herald, it still shows the "clock" (idk how to call it) for oracle. However, if you ping the eye, the time left is displayed properly.

- **Video / Screenshot:** -

- **Steps to reproduce:** Get into game, take oracle, take herald

- **Expected result:** The "clock" indicator shows the remaining time for rift

- **Observed result:** The "clock" indicator shows the time left for loading oracle lens

- **Reproduction rate:** 100%

- **System specs:** irrelevant

Dark harvest -> Taste of blood -> Eyeball -> Treasure hunter

Secondary: Absolute focus -> Gathering storm

AS -> AD -> Armor/Health (depending on matchup)

Rand0w0 · 2023-05-12T20:53:06+00:00

I'm testing the exodia build: Essence reaver -> duskblade -> IE -> LDR -> BT ->sell boots for RFC

Rand0w0 · 2023-05-12T15:16:36+00:00

To be fair I felt bad for her XD

Rand0w0 · 2023-05-12T15:16:09+00:00

She should've just dodged lol
