I am attending the 2018 Northeastern Educational Research Conference at Trumbull, CT. The travel is relatively painless (one hour of driving). The conference is held at Trumbull Marriott Shelton annually.The main objective for me this year is to present our work, Automated Text Analysis of Document and Reference Similarities - An Application of LDA Topic Modeling. The paper I submitted is somewhat on the technical side (like most of my writings). So I prepared a presentation similar to the paper. But after attending a couple sessions on Wednesday afternoon, I felt most o...

I just received an invitation for IBM's quantum computer access. I registered and tried and it turned out the experience is a little (well, sort of) different from what I expected. They first gave me a little 101 and explained quantum bits and basic laws of quantum physics. If you know some abstract algebra and are familiar with vectors, spaces, and tensor products, the introduction could make sense. Then I was directed to the graphical user interface the IBM team built for programming their quantum computers. The computer is definitely a computer. But it's more like the computer you see i...

A linebacker in NFL and Math Ph.D. at MIT. Yes, you heard it right. The Ravens linebacker John Urschel has been admitted to the Ph.D. program in Mathematics at MIT. And he decided to start his Ph.D. program this year. John Urschel graduated from Penn state with a 4.0 GPA in Mathematics. In addition, he also has a master's degree from the same institution. He would read math books and research papers when the Ravens are traveling. In fact, he is already an...

It seems that personalized learning has been gaining a lot of attention. The attitudes toward this idea is really divided. Some think this is a promising future; but others think it's expensive and has little effect. We even had seminar speakers who were strongly against this very idea. Here is a research report from RAND Corporation, one of the most important think tanks in the country. Despite having "Corporation" in its name, it is a nonprofit institution. The research found that person...

I just discovered that Springer publishing recently incorporated an interactive recommendation tool into their website. Check this out (You must be on the TC network). Right next to the list of related articles, there is an interactive graph that visually shows the connections of articles. You can choose different key terms or combination of key terms. The order of recommendations will change accordingly. You can play with it. The graph is produced with D3 - a popular front end data visualization tool....

I was looking at the New Learning Times (NLT) backend database and stumbled upon the most read NLT article ever. The article Serious Games Promote 21st Century Skills written and submitted by Ting on was viewed 36,569 times as of this morning. To put the number into perspective, the second most read article has 1,576 views. Edit: It is possible that this particular article has been linked somewhere. Since yesterday, this article has another 600 requests. I will investigate this behavior next week.

Many of our summer interns are future computer scientists/engineers. Coding is the foundation for a career in almost any computer or data related fields. I would like to share with you a great way to learn and practice coding. ACM International Collegiate Programming Contest (ACM ICPC) is the largest and most important programming contest in the world. Students from top CS schools around the world compete in this competition. The U.S. is divided into several different geographic regions. Teams from different schools compete regionally. The top two teams from each region will advance to the ...

Okay, it might sound a little nerdy. I've been thinking about modeling Vialogue conversations with a Hidden Markov Model (HMM) over the Halloween weekend. I briefly outlined the procedure. Any comments or suggestions? Hidden Markov Chain Approach A good conversation leads to learning Pre-test — determine the participants' initial cognitive patterns (i.e. mastery or non-mastery of different cognitive attributes). Divide participants into two groups. They both watch the same material. The first group is t...

Check this out. A text mining and machine learning tool with an user interface! This particular product is designed for classroom teachers. It automates the process of grading an essay. So yes, your essays will be graded by a machine. It's also open source. I might be able to take a look at it. See if we can use it on vialogues.
