Learning Management
An E-Learning Recommender That Helps Learners Find the Right Materials
Mbipom, Blessing (Robert Gordon University) | Massie, Stewart (Robert Gordon University) | Craw, Susan (Robert Gordon University)
Learning materials are increasingly available on the Web making them an excellent source of information for building e-Learning recommendation systems. However, learners often have difficulty finding the right materials to support their learning goals because they lack sufficient domain knowledge to craft effective queries that convey what they wish to learn. The unfamiliar vocabulary often used by domain experts creates a semantic gap between learners and experts, and also makes it difficult to map a learner's query to relevant learning materials. We build an e-Learning recommender system that uses background knowledge extracted from a collection of teaching materials and encyclopedia sources to support the refinement of learners' queries. Our approach allows us to bridge the gap between learners and teaching experts. We evaluate our method using a collection of realistic learner queries and a dataset of Machine Learning and Data Mining documents. Evaluation results show our method to outperform benchmark approaches and demonstrates its effectiveness in assisting learners to find the right materials.
Dropout Model Evaluation in MOOCs
Gardner, Joshua (The University of Michigan - Ann Arbor) | Brooks, Christopher (The University of Michigan - Ann Arbor)
The field of learning analytics needs to adopt a more rigorous approach for predictive model evaluation that matches the complex practice of model-building. In this work, we present a procedure to statistically test hypotheses about model performance which goes beyond the state-of-the-practice in the community to analyze both algorithms and feature extraction methods from raw data. We apply this method to a series of algorithms and feature sets derived from a large sample of Massive Open Online Courses (MOOCs). While a complete comparison of all potential modeling approaches is beyond the scope of this paper, we show that this approach reveals a large gap in dropout prediction performance between forum-, assignment-, and clickstream-based feature extraction methods, where the latter is significantly better than the former two, which are in turn indistinguishable from one another. This work has methodological implications for evaluating predictive or AI-based models of student success, and practical implications for the design and targeting of at-risk student models and interventions.
Online Learning for Structured Loss Spaces
Barman, Siddharth (Indian Institute of Science (IISc), Bangalore ) | Gopalan, Aditya (Indian Institute of Science (IISc), Bangalore ) | Saha, Aadirupa (Indian Institute of Science (IISc), Bangalore)
We consider prediction with expert advice when the loss vectors are assumed to lie in a set described by the sum of atomic norm balls. We derive a regret bound for a general version of the online mirror descent (OMD) algorithm that uses a combination of regularizers, each adapted to the constituent atomic norms. The general result recovers standard OMD regret bounds, and yields regret bounds for new structured settings where the loss vectors are (i) noisy versions of vectors from a low-dimensional subspace, (ii) sparse vectors corrupted with noise, and (iii) sparse perturbations of low-rank vectors. For the problem of online learning with structured losses, we also show lower bounds on regret in terms of rank and sparsity of the loss vectors, which implies lower bounds for the above additive loss settings as well.
Why AI Changes Your Relationship With LMS - eLearning Industry
Voltaire once said that the Holy Roman Empire was neither holy, nor Roman, nor an empire. We don't have to go quite as far in acknowledging the imbalance in the constituent parts of Learning Management Systems. And the learning that is there isn't delivered when learners really need it, nor in the form they need it. We need a new type of LMS for the way we want and need to learn today. With AI we have the potential to put learners at the center and at the same time have them better understand and manage their learning.
A new social contract between man and machine
The reality is that it's neither one. The fear is that automation is sweeping all before it, gobbling up jobs; displacing millions of workers and leaving them unemployed and, worse, unemployable; and exacerbating the income gap. It's reviled by many as a greater threat than jobs shipped overseas, even prompting some to suggest taxing robots to slow their spread. The counterview is that automation is not replacing jobs nearly fast enough. We don't have enough workers to do the jobs available now, and this will get worse as demographic trends play out.
Can a robot pass a university entrance exam?, Noriko Arai @TEDx
Why you should listen Noriko Arai is the program director of an AI challenge, Todai Robot Project, which asks the question: Can AI get into the University of Tokyo? The project aims to visualize both the possibilities and the limitation of current AI by setting a concrete goal: a software system that can pass university entrance exams. In 2015 and 2016, Todai Robot achieved top 20 percent in the exams, and passed more than 70 percent of the universities in Japan. The inventor of Reading Skill Test, in 2017 Arai conducted a large-scale survey on reading skills of high and junior high school students with Japan's Ministry of Education. The results revealed that more than half of junior high school students fail to comprehend sentences sampled from their textbooks.

Teaching The Next Generation To Work With AI
Recently I wrote about the growing importance of investing in the skills of employees so that they can adapt to the changing technology landscape they're working in. It was based upon a recent Accenture report, which argued that organizations need to take a systemic approach to ensuring the interaction between man and machine is a smooth one. Whilst generally corporate training budgets are on a downward trend, there are a couple of recent developments that suggest all is not entirely lost and small progress is being made. The first comes from Google, who have teamed up with MOOC pioneer Coursera to launch an online course for IT support professionals. It's estimated that IT support roles will grow by 10% by 2026, and the course is designed to learn the kind of skills required to land such a role.
Data Science in Python Pandas, Scikit-learn,Numpy Matplotlib
"This course has taught me many things I wanted to know about pandas. It covers everything since the installation steps, so it is very good for anyone willing to learn about data analysis in python /jupyter environment." "Good explanation, I have laready used two online tutorials on data -science and this one is more step by step, but it is good" "i have studied python from other sources as well but here i found it more basic and easy to grab especially for the beginners. I can say its best course till now . The average data scientist today earns $130,000 a year by glassdoor.
