How chatbots will help education
It's an exciting time for innovations in ed tech, and chatbots are at the forefront. Mobile apps are still compelling and there are many use cases where an app can provide the richest experience. However, the downside is that you still need to download them, log in, keep them updated, and make sure they work well with your devices. When it comes to sheer speed and convenience, nothing can beat a chatbot. So, what is a chatbot, anyway?
Sam Harris: Can we build AI without losing control over it? TED Talk • /r/MachineLearning
Given the votes on this post so far I foresee at best a lukewarm reaction to this on this sub; which kind of makes sense because this is more of a technical/research sub than a discussion sub. For general discourse I'd recommend /r/AIethics or /r/ControlProblem (although I prefer the former even if it's less active). To answer your question though. Harris talks about us not being able to marshal the appropriate response to an AI armageddon, but anyone familiar with the AI Winter (which probably includes many on this sub, which probably explains the dissatisfaction with AI-focused dystopian musings) knows that if anything, we've had a cultural overreaction to the threat of AI vs. what harm -- if any -- it's actually caused. Lots of people talk about how dangerous AI could be, and there are lots of movies made that stir up a lot of fear of the implications of AI, but what intelligent systems have actually done is help diagnose illness, learn to play video games, and give us a platform for doing tons of new and exciting things in the world.
Amazon, Google, Facebook, IBM, and Microsoft form AI non-profit ZDNet
Amazon, Google, Facebook, IBM, and Microsoft have announced they are forming a non-for-profit organisation to educate the public about artificial intelligence (AI) technologies, as well as alleviate anxieties around its application. The collective, which includes Google's AI subsidiary DeepMind, also plans to develop best practices on the challenges and opportunities within the field of AI. The organisation, called Partnership on Artificial Intelligence to Benefit People and Society (Partnership on AI), will address legal and ethical challenges that AI presents, encourage public discourse, and identify opportunities to use AI to bring improvements to society. The organisation does not intend to be a regulatory body, with a statement saying it does "not intend to lobby government or other policymaking bodies." Members of the Partnership on AI will conduct research, recommend best practices, and publish research under an open license in areas such as ethics, fairness, and inclusivity; transparency, privacy, and interoperability; collaboration between people and AI systems; and the trustworthiness, reliability, and robustness of the technology.
What is some tools that a Math graduate student must have to be competent in a Machine Learning Master? • /r/MachineLearning
I have studied Mathematics and got my degree and I am very interested in applying for a Master in Machine Learning. Of course my math background is high enough I believe. We did some coding like C, R, Matlab and worked SPSS. I've taken the Stamford Machine Learning coursera course and got a very very small taste of Machine Learning, so I guess what are other things I have to study to have a complete arsenal of tools. Thank you for your time.
Can a computer tell if you're RACIST? Algorithm can detect hidden prejudice from a person's body language
While many people have prejudices against certain groups, it can often be easy to hide these in public. But a new computer programme may soon be able to reveal these hidden biases. Researchers have created a programme that scrutinises people's body language for signs of racial prejudice. Researchers have created a programme that scrutinises people's body language for signs of racial prejudice. Researchers from the University of Modena and Reggio Emilia in Italy wanted to see if an algorithm could accurately predict if someone was racist.
To Make AI Less Biased, Give It a Worldview
One of the most difficult emerging problems when it comes to artificial intelligence is making sure that computers don't act like racist, sexist dicks. As it turns out, it's pretty tough to do: humans created and programmed them, and humans are often racist, sexist dicks. If we can program racism into computers, can we also train them to have a sense of fairness? Some experts believe that the large databases used to train modern machine learning programs reproduce existing human prejudices. To put it bluntly, as Microsoft researcher Kate Crawford did for the New York Times, AI has a white guy problem.
Multi-label Methods for Prediction with Sequential Data
Read, Jesse, Martino, Luca, Hollmén, Jaakko
The number of methods available for classification of multi-label data has increased rapidly over recent years, yet relatively few links have been made with the related task of classification of sequential data. If labels indices are considered as time indices, the problems can often be seen as equivalent. In this paper we detect and elaborate on connections between multi-label methods and Markovian models, and study the suitability of multi-label methods for prediction in sequential data. From this study we draw upon the most suitable techniques from the area and develop two novel competitive approaches which can be applied to either kind of data. We carry out an empirical evaluation investigating performance on real-world sequential-prediction tasks: electricity demand, and route prediction. As well as showing that several popular multi-label algorithms are in fact easily applicable to sequencing tasks, our novel approaches, which benefit from a unified view of these areas, prove very competitive against established methods. Keywords: multi-label classification; problem transformation; sequential data; sequence prediction; Markov models 1. Introduction Multi-label classification is the supervised learning problem where an instance is associated with multiple class variables (i.e., labels), rather than with a single class, as in traditional classification problems. See [1] for a review. Corresponding author, jesse.read@polytechnique.edu Preprint submitted to Pattern Recognition September 29, 2016 labels were modelled independently - at the expense of an increased computational cost. The case of binary labels is most common, where a positive class value denotes the relevance of the label (and the negative or null class denotes irrelevance). Typical examples of binary multi-label classification involve categorizing text documents and images, which can be assigned any subset of a particular label set. For example, an image can be associated with both labels beach and sunset. The multi-label classification paradigm has been successfully considered also in many other domains, such as text, video, audio, and bioinformatics - see [1] and references therein for further examples.
Eye-tracking technology shows that preschool teachers have implicit bias against black boys
For African American boys, the presumption of guilt starts before they have entered a kindergarten classroom, new research shows. In a study presented Wednesday to a meeting of education policy officials, researchers found that pre-K educators who were prompted to expect trouble in a classroom trained their gaze significantly longer on black students, especially boys, than they did on white students. When asked which of four videotaped children -- a boy and girl who were black and a pair who were white -- required their closest attention, educators black and white alike chose the study's African American boy most frequently. The study's white boy came in a distant second and two girls -- one white and one black -- drew the least scrutiny from the teachers. But when subjects in the new study were asked to rate the severity of a child's disruptive behavior and recommend consequences for it, race played a more unexpected role: African American pre-K educators, the study found, judged misbehavior attributed to a black child more harshly than did white educators.

Camera spots your hidden prejudices from your body language
ARE your hidden biases soon to be revealed? A computer program can unmask them by scrutinising people's body language for signs of prejudice. Algorithms can already accurately read people's emotions from their facial expressions or speech patterns. So a team of researchers in Italy wondered if they could be used to uncover people's hidden racial biases. First, they asked 32 white college students to fill out two questionnaires. One was designed to suss out their explicit biases, while the second, an Implicit Association Test, aimed to uncover their subconscious racial biases.
