Limits of 'machine learning'

#artificialintelligence

Suppose you are driving a hybrid car with a personalised Alexa prototype and happen to witness a road accident. Will your Alexa automatically stop the car to help the victim or call an ambulance? Probably, it would act according to the algorithm programmed into it that demands the user's command. But as a fellow traveller with Alexa, what would you do? If you are an empathetic human being, you would try to administer first aid and take the victim to a nearby hospital in your car.


How to Compare Machine Learning Algorithms

#artificialintelligence

Under the RAM model [1], the "time" an algorithm takes is measured by the elementary operations of the algorithm. While users and developers may concern more about the wall clock time an algorithm takes to train the models, it would be fairer to use the standard worst case computational time complexity to compare the time the models take to train. Using computational complexity has the benefits of ignoring the differences like the computer power and architecture used at runtime and the underlying programming language, allowing users to focus on the fundamental differences of the elementary operations of the algorithms. Note that the time complexity can be very different during training and testing. For example, parametric models like linear regression could have long training time but they are efficient during test time.


Fairness in Machine Learning - Science in the News

#artificialintelligence

It's no secret that bias is present everywhere in our society, from our educational institutions to the criminal justice system. The manifestation of this bias can be as seemingly trivial as the timing of a judge's lunch break or, more often, as fraught as race or economic class. We tend to attribute such discrimination to our own internalized prejudices and our inability to make decisions in truly objective ways. Because of this, machine learning algorithms seem like a compelling solution: we can write software to look at the data, crunch the numbers, and tell us what decision we should make.

This Young Innovator Is A Champion Of AI For Good

#artificialintelligence

At the AIMed conference 2019, UCI's sophomore, and Dalai Lama Scholar Karishma Muthukumar gave an opening speech about her idea of using empathy-based artificial intelligence to improve human connection in the healthcare field. AIMed conference is an annual conference dedicated to bringing technologists, entrepreneurs, clinicians, and healthcare professionals to define AI-enabled solutions to create efficient, humane, and patient-centric solutions for the future of medicine. At the age of 14, while she was in high school, Karishma came up with the idea of using an emoji-based communication board for patients with Locked-in Syndrome. These patients are mentally aware but unable to move or verbally communicate. Her emoji-based communication board, OutLoud, won the abstract competition for Artificial Intelligence and Big Data in the International Society of Pediatric Innovation's annual Pediatrics 2040 conference. In 2018, she was named the 2018 Young Innovators to Watch, a national scholarship program by Living in Digital Times and Lenovo.


stream-learn -- open-source Python library for difficult data stream batch analysis

arXiv.org Machine Learning

stream-learn is a Python package compatible with scikit-learn and developed for the drifting and imbalanced data stream analysis. I ts main component is a stream generator, which allows to produce a synthet ic data stream that may incorporate each of the three main concept drift typ es (i.e. The package allows conducting experiments following estab lished evaluation methodologies (i.e. In addition, estimators adapted for data stream classification have been implem ented, including both simple classifiers and state-of-art chunk-based and online classifier ensembles. To improve computational efficiency, package utili ses its own implementations of prediction metrics for imbalanced binary cla ssification tasks. Keywords: Data stream, Concept drift, Imbalanced data, Dynamic class imbalance 1. Motivation and significance Pattern recognition research increasingly goes beyond the usual pattern of building classification models on stationary data sets an d focuses on data stream processing where class distributions, and hence als o decision boundaries, may change over time [1].


Causal query in observational data with hidden variables

arXiv.org Artificial Intelligence

This paper discusses the problem of causal query in observational data with hidden variables, with the aim of seeking the change of an outcome when "manipulating" a variable while given a set of plausible confounding variables which affect the manipulated variable and the outcome. Such an "experiment on data" to estimate the causal effect of the manipulated variable is useful for validating an experiment design using historical data or for exploring con-founders when studying a new relationship. However, existing data-driven methods for causal effect estimation face some major challenges, including poor scalability with high dimensional data, low estimation accuracy due to heuristics used by the global causal structure learning algorithms, and the assumption of causal sufficiency when hidden variables are inevitable in data. In this paper, we develop theorems for using local search to find a superset of the adjustment (or confounding) variables for causal effect estimation from observational data under a realistic pretreatment assumption. The theorems ensure that the unbiased estimate of causal effect is obtained in the set of causal effects estimated by the superset of adjustment variables. Based on the developed theorems, we propose a data-driven algorithm for causal query. Experiments show that the proposed algorithm is faster and produces better causal effect estimation than an existing data-driven causal effect estimation method with hidden variables. The causal effects estimated by the algorithm are as good as those by the state-of-the-art methods using domain knowledge.


Creating Collisions That Help Keep Local Tech Talent at Home

#artificialintelligence

Creating opportunities for collisions where computer science students, academia and industry can interact, share ideas and launch innovative programs is critical if Windsor is to attract and retain the best and brightest in the emerging technology workforce. Dr. Ziad Kobti, director of the school of computer science at the University of Windsor, believes these opportunities – including spaces and programs – need to be open to the public so that potential students can determine whether the fast-growing field is part of their future. "It can't only be done behind closed doors between academia and industry," said Kobti recently. "We have to create opportunities and settings where people can come and chat with someone and exchange ideas." Kobti believes the Windsor region needs to create these networking opportunities for students and industry so that talent can be identified, nurtured and convinced to remain in the Windsor area.


Design Thinking: Future-proof Yourself from AI

#artificialintelligence

It may not have been "The Matrix"[1], but the machines look like they are finally poised to take our jobs. Machines powered by artificial intelligence and machine learning process data faster, aren't hindered by stupid human biases, don't waste time with gossip on social media and don't demand raises or more days off. Figure 1: Is Artificial Intelligence Putting Humans Out of Work? While there is a high probability that machine learning and artificial intelligence will play an important role in whatever job you hold in the future, there is one way to "future-proof" your career…embrace the power of design thinking. I have written about design thinking before (see the blog "Can Design Thinking Unleash Organizational Innovation?"), but I want to use this blog to provide more specifics about what it is about design thinking that can help you to harness the power of machine learning…instead of machine learning (and The Matrix) harnessing you. Design thinking is defined as human-centric design that builds upon the deep understanding of our users (e.g., their tendencies, propensities, inclinations, behaviors) to generate ideas, build prototypes, share what you've made, embrace the art of failure (i.e., fail fast but learn faster) and eventually put your innovative solution out into the world.
