Machine Learning for Recommender Systems - A Primer

#artificialintelligence

The growth of ecommerce in the recent past can only be described as explosive and sweeping across the planet. According to a 2016 study, half of all dollars spent online in America belong to Amazon. And consider this, Recommendation Engines alone drive 35% of that revenue. But it is not ecommerce alone that's reaping the huge benefits that recommendation engines have to offer. Direct to device streaming services such as Netflix, Spotify among others, analyze user behavior almost to a micro moment level, then gather data surrounding similar users who are likely to buy the same items based on their browsing history, and provide that much needed nudge to move on to the next purchase on the platform.


Emerging Education Technologies Engaging Students and Enhancing Learning Outcomes With Instructional Technologies and Active Learning

#artificialintelligence

In the last few years, numerous developments have led to a growing awareness of the maturity of Artificial Intelligence. Self-driving cars and personal assistants like Alexa and Siri are some of the consumer-facing technologies that have helped to fuel this awareness. This knowledge can also bring with it a certain dystopian fear about robots and technology "taking over". While we should always strive to be cautious with new technologies, our concerns should also be tempered by understanding the long curve of development that typically precedes these seemingly overnight maturings of technology.


Intelligent Tutoring Systems (a Decades-old Application of AI in Education)

Self-driving cars and personal assistants like Alexa and Siri are some of the consumer-facing technologies that have helped to fuel this awareness. This knowledge can also bring with it a certain dystopian fear about robots and technology "taking over". While we should always strive to be cautious with new technologies, our concerns should also be tempered by understanding the long curve of development that typically precedes these seemingly overnight maturings of technology. I've been reading Artificial Intelligence in Education, a 2019 publication by Wayne Holmes, Maya Bialik, and Charles Fadel, that explores implications of AI in the realm of teaching and learning.


How Machine Learning Automates Business Processes

#artificialintelligence

And they're coming for your business -- with the power to build or destroy your ability to compete in the near future. "Those companies not considering investing and innovating will soon be outperformed by the new economy that runs on machine learning" Machine learning is already changing the world. As a key subset of artificial intelligence (AI), it enables computers to act and learn on their own, without being specifically programmed, by utilizing data and experience rather than being explicitly programmed. Self-driving cars, Netflix recommendations, and virtual personal assistants like Siri and Alexa are some of AI's best-known applications. One of the most immediate ways businesses use machine learning to improve their competitiveness is by automating back-office processes, the majority of which are high volume, rules-based functions that could seamlessly operate on a "lights out" basis, freeing up employees' time for achieving more strategic company objectives.

Not just your average virtual assistant: a day in the life of an IVE - Blackzendo NXS

#artificialintelligence

Meet Ivey! Ivey is an Intelligent Virtual Entity (IVE) who is designed to work as a marketing assistant at a major corporation. As an AI-powered virtual employee, she carries out certain pre-scheduled tasks on a regular basis--but she does much more than just that. Ivey can understand the virtual environment she works in, prioritize and schedule her own tasks, and interact with her "boss" John using natural language. She can perform complex analytical processes, and -- much like a human employee -- she can learn and improve based on feedback from her environment (and her boss). What does this look like in practical terms?


A Contextual-Bandit Approach to Online Learning to Rank for Relevance and Diversity

arXiv.org Machine Learning

Online learning to rank (LTR) focuses on learning a policy from user interactions that builds a list of items sorted in decreasing order of the item utility. It is a core area in modern interactive systems, such as search engines, recommender systems, or conversational assistants. Previous online LTR approaches either assume the relevance of an item in the list to be independent of other items in the list or the relevance of an item to be a submodular function of the utility of the list. The former type of approach may result in a list of low diversity that has relevant items covering the same aspects, while the latter approaches may lead to a highly diversified list but with some non-relevant items. In this paper, we study an online LTR problem that considers both item relevance and topical diversity. We assume cascading user behavior, where a user browses the displayed list of items from top to bottom and clicks the first attractive item and stops browsing the rest. We propose a hybrid contextual bandit approach, called CascadeHybrid, for solving this problem. CascadeHybrid models item relevance and topical diversity using two independent functions and simultaneously learns those functions from user click feedback. We derive a gap-free bound on the n-step regret of CascadeHybrid. We conduct experiments to evaluate CascadeHybrid on the MovieLens and Yahoo music datasets. Our experimental results show that CascadeHybrid outperforms the baselines on both datasets.


Towards an Integrative Educational Recommender for Lifelong Learners

arXiv.org Artificial Intelligence

One of the most ambitious use cases of computer-assisted learning is to build a recommendation system for lifelong learning. Most recommender algorithms exploit similarities between content and users, overseeing the necessity to leverage sensible learning trajectories for the learner. Lifelong learning thus presents unique challenges, requiring scalable and transparent models that can account for learner knowledge and content novelty simultaneously, while also retaining accurate learners representations for long periods of time. We attempt to build a novel educational recommender, that relies on an integrative approach combining multiple drivers of learners engagement. Our first step towards this goal is TrueLearn, which models content novelty and background knowledge of learners and achieves promising performance while retaining a human interpretable learner model.


Maximize The Promise And Minimize The Perils Of Artificial Intelligence (AI)

#artificialintelligence

How businesses can use artificial intelligence (AI) to their advantage, perhaps even in a ... [ ] transformative way, without turning the pursuit of AI advantage into a quixotic quest Frankly, I was hoping an artificial intelligence (AI) algorithm would write this column for me, because who knows more about AI than the mysterious little gremlins that make "machine learning" possible? That, alas, didn't happen; so I'm on my own. Like most people in business, I don't need any convincing that artificial intelligence (for most companies in many areas of their operations) will become a game-changer. Still, it remains a fluid, if not amorphous, concept in many respects. What, exactly, can we expect AI to do for us that we're not already doing--or how will it improve what we're doing by doing it better, faster, cheaper, with greater insight or fewer errors?
