Our latest work on developing Student-Centric Models based on LMS data got published in @EDMConf2021 . In this work, we report new methods to develop student-based models instead of course-specific models and discuss the relation between student demographics and LMS behaviors.

@hughesanalytics Hope you don't get any effects. Its lot better to get this booster based on what I am seeing from preliminary research studies. #Pfizer

@ShuklaPiyushi @OpenAcademics Apart from this, one of the best books out there is "An Introduction to Statistical learning with applications in R"

[Varun @var143]

@ShuklaPiyushi @OpenAcademics Learn basics from free courses. Work on logical thinking. This can only be achieved by programming for different requirements. If you improve logical thinking, it doesn't matter you code in python or R. All the syntaxes are available online. You should know what to search for.

[Varun @var143]

That makes sense.

One of my collaborative research work on studying speaking anxiety of English Language Learner got highlighted in @empatica Research Article. This area needs to be explored by researchers to identify methods that minimize foreign language anxiety. #anxiety

Awesome. @RapidMiner is the best platform for both expert and citizen data scientists. I also encourage aspiring data scientists to start with RapidMiner as you can gain a lot of knowledge by spending time on community and spinning up models quickly. Check it out!!

[Scott Genzer @sgenzer]

Well done team @RapidMiner 💪🏼💪🏼. Such a privilege to be a part of this.

[Varun @var143]

Our recent study on #KnowledgeTracing with #BigData is posted on @RapidMiner social media channels. This work also utilized @RapidMiner AI explainability capabilities to study student correctness prediction. Check it out!!

There are multiple applications of #VR in #Psychology domain. In this work, we developed a #VR system to study food choices in young adults. Studies like this will help resolve obesity and health issues at young ages. #obesity #food https://t.co/Db0lqosVLZ

On the largest data (780K Students) publicly available in education domain the performance improvement of #DeepLearning models to predict next problem correctness is minimal and with careful feature engineering Logistic Reg models performed simlarly
