Computer-Aided Assessment


EPICOLOR Uses Artificial Intelligence to Grade Your Footage Automatically

#artificialintelligence

To be clear, your computer is likely not powerful enough to run an artificial intelligence engine itself, and definitely can't do so within a plugin. Likely, a tremendous volume of imagery was processed and analyzed in a neural network to craft a target for what a pleasing image is, and then EPICOLOR uses that processing to look at your footage and convert it into something more attractive. The above image is a side-by-side of the EPICOLOR auto color and the auto color from Resolve, taken from EPICOLOR's own demo imagery. While automated grading isn't going to come for professional color jobs just yet, there are going to be lots of applications where a quick and dirty auto grade is going to get used to keep the post workflow moving faster than it was before.


Machine learning could soon determine everything about creating webpages, says Unbounce

#artificialintelligence

With breakthroughs in machine learning happening every day, more and more column inches are being devoted to the prospect that super-intelligent computers are right around the corner--and that they'll soon take over people's jobs. A business that allows organizations to easily design landing pages and test which variants perform best, Unbounce has recently created a system that asks computers to grade a site's homepage on how likely visitors are to engage with it. Asking players to predict whether a landing page had a conversion rate that was higher or lower than average, the app saw users assess nearly 18,000 webpage screenshots over two days. Aiming to determine a definitive causal link between a landing page's language and its conversion rate, the company will contribute to the growing revolution of machine learning.


Cross-Language Plagiarism Detection System Using Latent Semantic Analysis and Learning Vector Quantization

#artificialintelligence

Computerized cross-language plagiarism detection has recently become essential. With the scarcity of scientific publications in Bahasa Indonesia, many Indonesian authors frequently consult publications in English in order to boost the quantity of scientific publications in Bahasa Indonesia (which is currently rising). Due to the syntax disparity between Bahasa Indonesia and English, most of the existing methods for automated cross-language plagiarism detection do not provide satisfactory results. The results of the experiments showed that the best accuracy achieved is 87% with a document size of 6 words, and the document definition size must be kept below 10 words in order to maintain high accuracy.


The End Of Multiple Choice? The Quest To Create Accurate Robot Essay Graders

What's the best way to prove you "know" something? A. Multiple choice tests B. Essays C. Interviews D. None of the above Go ahead: argue with the premise of the question. Oh yeah, you can't do that on multiple-choice tests. Essays can often better gauge what you know. Writing is integral to many jobs. But despite the fact that everyone can acknowledge that they're a more useful metric, we don't demand students write much on standardized tests because it's daunting to even imagine grading millions of essays.



Competing with Machine Learning

Almost 500,000 of the world's top data scientists compete on Kaggle to solve important problems for industry, government, and academia. Kaggle has catalyzed breakthroughs in areas ranging from automated essay grading to automated disease diagnosis from medical images. Before cofounding Kaggle in 2010, Anthony was an econometrician at the Australian treasury.


Automated Essay Evaluation: The Criterion Online Writing Service

AI Magazine

In this article, we describe a deployed educational technology application: the Criterion Online Essay Evaluation Service, a web-based system that provides automated scoring and evaluation of student essays. Criterion has two complementary applications: (1) CritiqueWriting Analysis Tools, a suite of programs that detect errors in grammar, usage, and mechanics, that identify discourse elements in the essay, and that recognize potentially undesirable elements of style, and (2) e-rater version 2.0, an automated essay scoring system. Critique and e-rater provide students with feedback that is specific to their writing in order to help them improve their writing skills and is intended to be used under the instruction of a classroom teacher. All of these capabilities outperform baseline algorithms, and some of the tools agree with human judges in their evaluations as often as two judges agree with each other.
