Как держать ученика в «зоне потока»: адаптивная сложность на IRT и Elo — и почему я не поверил ей без симуляции
Модель адаптивной сложности выглядела безупречно: формулы верны, тесты зелёные. Симуляция показала, что новички получают 58% верных ответов вместо 82%. Рассказываю, как устроена модель и где был провал.

Лейтнер, Elo и поправка на угадывание: движок тренажёра собесов без единого вызова LLM
Готовиться к собесу по списку «2000 вопросов с ответами» невозможно. Я пробовал: открываешь, листаешь минут сорок, отвечаешь на те, что и так знаешь, закрываешь с чувством выполненного долга. Через неделю в голове ноль. Список не помнит, где ты плаваешь, и не знает, когда ты забудешь то, что вчера повторил. Лечится это не списком подлиннее, а движком практики: системой, которая помнит каждую встречу человека с каждым вопросом и решает, что показать следующим. Такой движок я собрал для своего тренажёра собесов, и статья целиком про него: корзины Лейтнера для памяти, Elo с поправкой на угадывание для сложности, карта слабых мест, политика сборки сессии. Всё с кодом, графиками и граблями с прода, плюс два отступления: чем в этой задаче неудобен LLM и откуда берётся банк вопросов. Сам я ведущий дата-сайентист, кандидатов собеседую регулярно, так что на проблему смотрю с обеих сторон стола.

@guyjantic If you have not only one, but multiple questions, several item response models extend this logic by assuming a latent continuous variable:
they evaluate whether the responses to the questions can be reconstructed as ordered responses - and ordered in this case meaning 'with reference to this latent variable' (e.g., does being more in favour of rights for pregnant people consistently align with choosing higher categories in the individual question responses).
#rstats #stats #IRT #scaledevelopment
Thinking about scale reliability lately.
An obvious thing to remember is that scale reliability (omega) is the upper bound of correlations it can meaningfully (!) have with anything else.
This is highly practical, because, in theory (I haven’t fleshed this out yet), this enables us to test construct validity pretty well by attenuating correlations with reliability. This has been done before, albeit (imho) slightly clumsily by Kristof (1983). They used a Spearman Brown approach based on an ideal correlation to establish thresholds a correlation must test against to conclude discriminant or convergent validity. The formula was threshold = rho_ideal * sqrt(rel_a * rel_b). This is less than ideal, because what an ideal correlation is is up to the researcher.
However, keeping the above fact in mind, we can do better. Kill thresholds and just make it a measure of relatedness altogether that is capped by the lower reliability.
Let’s call this Kappa = rho_real/sqrt(rel_a*rel_b).
This should (again, I haven’t tested this yet) give you two types of information right away:
1)If its >1, then your scale is off.
2)If it’s less than 1 it informs about construct validity. If it’s less than 0.5, probably discriminant, if it’s higher probably convergent. The extreme the score, the higher the confidence.
Please correct me If I'm doing some goofing here.

Please welcome the new #publicTransport system.
This obviously is not a train and misses the extreme savings from steel #railway #train technics. But it's a giant step forward in the thinking about how to handle and speed up city traffic by public mass transport.
The top 1/4 of most intelligent chinese are more than the entire population of the US.
In the end maybe they might save us all ..

On 6 September 2023, there was signing ceremony for #MoU between #Iskandar Regional Development Authority (#IRDA) & Korea Railroad Research Institute (#KRRI).
The MoU is to carry out Proof of Concept (#POC) for Traffic Signal Prioritization System (#TSPS) related to the Iskandar Rapid Transit (#IRT) project.
The POC will help IRT in terms of efficient operation & smooth traffic along the #Tebrau IRT Main Trunk at Jalan Tebrau when it is implemented soon.

After much delay over the years, Johor Bahru’s Bus Rapid Transit (#BRT) is targeted for stage-one operation rollout by the third quarter of 2025.
Deemed as the backbone of the Iskandar region’s revamped #publictransport system known as Iskandar Rapid Transit (#IRT), the 55km high-capacity dedicated #buslane is set to feature three lines, namely #IskandarPuteri with 15km stretch, #Skudai (18km), and #Tebrau (22km).

I am still a fan of what #IRT #ItemBanking methods can deliver in the space where items can be reduced to one (or multiple linked) dimensions.
Just highlighting this visionary paper that inspired me during the time of my PhD greatly
https://rdcu.be/dku0h
and where we until today have done little to reach the full potential of such applications.
@pgmj Interesting. I struggle to find any #CTT in there, but that probably depends on where one chooses to put categorical data factor models; and whether CTT approaches are considered to be latent variable models or not.
I would agree that it does not cover #IRT models in general, or #RaschModels in particular.

@solderandchaos The other system is #IRT (integrated reservation ticket). As the name says, that is when tickets are sold with an integrated #reservation. To people accustomed to those, traveling without a reserved seat sounds very odd. Such operators are SNCF, Renfe, Trenitalia, SJ, Eurostar etc. For them, to get a reservation for Interrail you typically buy a "normal" ticket *but* apply a discount for pass holders which results in that effectively you only pay for a "reservation". #TrainTravel
#hello people. Ståle from Norway. I've been doing tactical and strategic #infosec and #irt in #HigherED for the last seven years. It all started with a bunch of diskettes and c.o.l.a. in 1993, and since then I've worked as a sysadmin. Mostly unix-es, but also Windows. This includes project management, #monitoring, #architecture, designing an #operations center and touching a bunch of technologies over the years. I still code a little #shell and #python. Been using #cfengine and #tivoli with a smile.
A memorable moment still is opening 7 xterms and compiling X11R6 for #sunos #solaris #hp-ux #ultrix #irix #linux #digitalunix and managing the configuration and security of tons of servers and clients centrally. This must have been 2000 or so.
These days I tend to like logging and #siem frameworks like #elk, teaching users and management how to make smart choices, general config management and hardening, IAM-stuff and the essential symbiosis between #sysadmin stuff and infosec stuff. #isms. #policies. #architecture.
I also like #photography #lego #rpg #larp #cooking #politics #society #emacs #languages #puns. A lot nicer than the picture. He/Him.
I work as an Assoc. Prof. at Pamukkale University on #EducationalMeasurement #Psychometrics field. I'm also a researcher at Boğaziçi University Adaptive Test Lab (#BATLAB)
My main research area includes #ItemResponseTheory (#IRT) #ComputerizedAdaptiveTesting (#CAT) and I'm happy to use #rstats and #Concerto for my studies.
I also want to add some personal tags: #PlayStation #PS #Xbox #Metal #Homebrew
