Students learn more efficiently when they are confidently engaged. And deep learning affords such engagement.
Global AI tutor provider and a member company of the Born2Global Centre, Riiid shows why in a recent real-world study demonstrating how personalized intelligent tutoring systems (ITS) predicting precise test results with deep learning algorithms can boost student enthusiasm, energize motivation, and will eventually fuel further business growth.
The paper "Prescribing Deep Attentive Score Prediction Attracts Improved Student Engagement" was recently accepted by top-tier education gathering EDM 2020 (Educational Data Mining), the 13th annual international conference on data mining, happening virtually July 10-13, 2020.
Conducting a detailed A/B test featuring two models – a collaborative filtering algorithm and a deep-learning algorithm – Riiid researchers examined about 78,000 users and their accompanying indexes indicating motivation and engagement. Those factors included test completion rate, registration rate, number of questions solved, conversation rate, and average revenue per user.
Every index showed consistent improvement with the deep-learning algorithm.
Riiid's deep-learning score prediction model tested in this research runs with "assessment modeling," the fundamental pre-training tasks for interactive educational systems. The firm's researchers proposed the pre-train and fine-tune methods of predicting exam scores with student-system interaction data when label data - the actual exam score data in this case - is scarce.
This new scores prediction model showed 36.8% higher accuracy compared to the previous model in terms of MAE (Mean Absolute Error).
The study concludes perceived precision of predicted scores increased test-takers' confidence in solutions, which in turn encourages more active engagement.
One reviewer said, "This is an excellent, practical example of closing the loop from model prediction to actual tangible benefits."
The study was one of the few done prospectively in a real-world setting, as opposed to retrospectively. The results are more realistic when taken outside a laboratory setting, providing more of a tangible value than mere theory.
"Even for AI scientists, most of the time, it is challenging to answer what areas a certain deep learning technology can be implemented in and drive meaningful impact," said Youngnam Lee, Riiid's researcher and the lead author. "This research was only possible because functions of AI research and product operations are tightly aligned and work together at Riiid."
Riiid deployed a deep-learning prediction model to all the users, expecting a higher level of user engagement bringing improved learning efficacy.
Putting utmost efforts in R&D to advance its AI models to enhance their functions, Riiid strives to earn users' trust and drive active engagement - both of which are direct indicators of business growth, as this study shows.
"Riiid's AI doesn't just present a better way of learning; it has great measurable value for business," said YJ Jang, CEO and co-founder of Riiid. "We will continue to study and research fundamental AI tech that brings real-world industrial impact proven through decisive and rapid deployment. We will keep creating unprecedented cases appreciated by the business and academic communities."

The AI tutoring solution company Riiid, a member company of the Born2Global Centre, has secured $18 million through its Series C funding round, which was led by Premier Partners, Alpenroute Asset Management, DSC Investment, IMM Investment, Korea Growth Investment Corporation, and D Ventures Private Investment Fund. Such recapitalizations, in which DSC Investment is participating for the third time, have consistently served as stepping stones for Riiid's growth since the company's earliest years.
Riiid, an edutech startup, has published the results of its research on its one-on-one AI tutoring deep-learning technology in an academic journal and is currently providing independently developed AI technology as a B2B solution known as "santA.Inside." A team of over 30 researchers from prominent Korean and overseas universities (UC Berkeley, Yale, Seoul National University, KAIST, POSTECH, Korea University, and Hanyang University), all of whom hold master's or doctoral degrees in mathematics or computer science, is working to continuously develop and improve santA.Inside.
Riiid was also the first Korean company to present a research paper on AI technology at the Conference on Neural Information Processing Systems (NIPS), the world's most authoritative conference on artificial intelligence. The company continues to receive acknowledgment for its AI technologies not only in Korea but in the United States, China, and Japan as well, with a total of 41 registered patents and patent applications.
Having already secured a cumulative total of $18M in R&D investment, Riiid will be using most of its recently raised Series C investment to conduct R&D and further enhance santA.Inside.
A B2B service that is also Riiid's main business, santA.Inside can be easily used by any education company interested in using AI technology to provide educational services that transcend human capability. The solution allows companies to launch their own AI educational service brands.
Santa TOEIC is the first AI tutoring product that Riiid has developed, as a test product based on santA.Inside, aiming to introduce the AI tutoring service concept to the Korean educational market. An AI tutoring service exclusively for TOEIC students that has already secured a cumulative total of 900,000 members, Santa TOEIC can predict a user's score after he or she completes only 6 to 10 problems. It can also curate individually tailored problem and lecture banks in real-time and design the most efficient learning patterns and schedules.
Riiid's analysis of the rate of increase of the TOEIC scores of Santa TOEIC users compared to their usage times shows that, on average, 20 hours of learning results in an increase of 124 points. In late 2017, the service was converted into a paid service. Compared to the first quarter of 2018, sales for the first quarter of 2019 increased by 255 percent. As evidence of the proliferation of its AI tutor, Riiid announced that, on average, Santa TOEIC users solve a total of 910 problems, which is roughly equivalent to 1.5 paper workbooks (most users of paper workbooks solve fewer than 100 problems, after which they essentially stop learning).

NEOFECT, K-ICT Born2Global Centre's member company, develops medical devices and software for stroke patients and people suffering from neurological or musculoskeletal diseases. At CES, the world's largest electronic device trade show, in 2017, NEOFECT received an Innovation Award for its RAPAEL Smart Glove, a rehabilitation device for the hands, wrists, and lower arms of stroke patients. More recently, the company received its second consecutive Innovation Award at CES 2018 for its RAPAEL Smart Pegboard, a rehabilitation device designed for stroke patients' hands and arms.
NeoFect received its second consecutive Innovation Award at CES 2018 for its RAPAEL Smart Pegboard,
a rehabilitation device designed for stroke patients’ hands and arms.
The main feature of NEOFECT's RAPAEL series is its use of games. Unlike other rehabilitation device companies, the majority of which offer products that involve the repetition of simple and boring movements, NEOFECT has introduced a game-based element to its devices to make rehabilitation activities more entertaining and effective.
The company's most recent release is the RAPAEL smart pegboard, which, simply put, is a digital version of the traditional wooden pegboard. With this device, the patient engages in rehabilitative training by grasping and placing wooden pegs into a board in accordance with the rules of the selected game. The purpose of pegboard training is to enhance hand-eye coordination, fine motor skills, cognitive ability, space perception, and concentration.
The 63 high-luminance LEDs installed on the board light up to show the user where to place the pegs. For example, when playing the whack-a-mole game, only the holes where the user is expected to place the peg light up. To have patients make shapes, the lights create the shape of a heart or arrow, among others. The device also provides audio feedback through a speaker embedded in the board that notifies the user of his or her progress through sound effects and voice.
Harnessing painful experiences and applying them to the creation of a patient rehabilitation solution
CEO Ban Ho-young was always interested in rehabilitative treatment. "My father and uncle both died from stroke. In both cases, it was very difficult to have to just stand by and watch them suffer. During those experiences, I noticed the lack of rehabilitation methods available for patients who have lost most of their motor abilities and began thinking about how to resolve that problem." A university friend of Ban's who was studying rehabilitative medicine at the time shared his views and suggested starting a company together, thus giving birth to NEOFECT.
Practical feedback is just as important as research in the lab
Ban believes that the greatest strengths of NEOFECT products are practicality and convenience. As an engineering major, Ban was confident about his ability to develop machines and solutions, but knew that he lacked medical expertise. "I visited rehabilitation centers literally hundreds and thousands of times. I met with patients, doctors, and physical therapists to get as accurate a picture as possible of the rehabilitation process." This direct feedback from the field, which we had not considered in his first product designs, was then applied to the creation of NEOFECT's final products.
Another strength of the company's products is convenience. Most rehabilitation equipment is very costly (hundreds of millions of Korean won) and quite large, which is why they are available only in hospitals. As a result, patients who are determined to get well have no choice but to undergo rehabilitation at a hospital.
Pioneering a next-generation medical device market under the Fourth Industrial Revolution
Unlike other rehabilitation solution companies, which have focused mainly on hardware development, NEOFECT has grown based on its prioritization of both software and hardware. It is currently developing a rehabilitation solution that involves the use of AI and IoT. Ban said, "Big data is the key. We will be thoroughly analyzing the movements that enable patients to recover their neurological functions more quickly."
To develop new products, Ban is also actively striving to attract investment. As of last year, the company's annual sales stand at around KRW 2.1 billion, but it has already accumulated KRW 13.5 billion in investment, meaning that many companies are very optimistic about NEOFECT's potential. The list of NEOFECT investors includes a number of famous KOSDAQ-listed venture capital companies, including DSC Investment and Company K.
After receiving consultations from the Born2Global Centre on patents and two areas of accounting, NEOFECT was able to conduct its business more effectively. The company's transaction method, which had primarily been B2B, was changed to include more B2C transactions in 2017, allowing NEOFECT to help more patients with their rehabilitation efforts.
Kiwontechwill soon be launching its AI-integrated email security solution platform in Japan.
A member company of the K-ICT Born2Global Centre, Kiwontech recently announced that it will be expanding sales of its AI email security solution platform in Japan as part of a business partnership with Taiyo Tsushin Kogyo, with which Kiwontech signed an MOU in March. The value of the platform is expected to exceed USD 200,000 (approx. JPY 20 million).
Kiwontech is currently operating its email security platform business in Japan in cooperation with the medium-sized webhosting company Fairway, which is acting as its distributor in the country. The products being sold include an email system and sender/receiver security.
Developed entirely independently by Kiwontech, SCM GUARD is a personnel optimization AI email security solution, checking every user's received and outgoing email information. It detects malicious emailsutilizing AI despite of receiving many large attachment files at same time. The AI engine blocks new kinds of ransomware and malicious code by verifying the number of cases that can be activated when a user opens an email.
Kiwontech CEO Kim Dong-cheol said, "SCM GUARD has a function that analyzes and screens various potential threats posed by unprocessed electronic mail and can preemptively detect emails that display any suspicious characteristics, such as those related to APT attacks or spear phishing, or have any other features that are out of the ordinary. Thanks to SCM GUARD's ability to screen malicious emails that appear to have been sent from actual addresses, we believe that the product will be highly welcomed in Japan. Going forward, we will continue to do our best to ensure that our AI email security solution platform enters the global market as soon as possible."
Starting with Taiyo Tsushin Kogyo, a manufacturer and seller of materials for the construction of telecommunications infrastructure, Kiwontech hopes to steadily expand its business activities in Japan by creating a sponsorship group that includes Iroku, Notoice, Tetris, PR Soft, and UNIARK.
The seminar on SCM GUARD will be held on the 15th at 16:30~18:30 of this month at Osaka Building 6F, MJE WORK seminar room in Osaka.

Cyber security is an increasingly important issue.
Large companies have played victim to some very public attacks;
Sony Pictures Entertainment was the victim of a cyber attack in November 2014
that revealed personal information of its employees.
Target also discoverd malwareon its point-of-sale systems in December 2013.
According to a Raicati Email Statistics Report released in 2015,
77 percent of all malware are installed via email.
39% of total malware installations were from attached files in the email
with 34% coming from embedded links in the email.
“Many Mac users think they are safe, but they are also vulnerable to cyber attacks.
Same goes for Gmail users.
If you leave it on default, it detects the malware, but if you change encoding,
it is vulnerable to malware attacks,” CEO of SecuLetter, Chasung Lim told TechNode.
SecuLetter protects the email server from advanced attacks
and cloud services to protect email server,
using Hybrid Analysis method to detect and block cyber attacks.
“If an antivirus software detected a cyber attack, it means that the attack is already well-known.
New kinds of attack such as spear phishing, ransomware, and other targeted attacks
can get through existing security solutions and penetrate a company’s security layer,” Mr. Lim says.
