Many data mining tasks cannot be completely addressed by automated processes, such as sentiment analysis and image classification. Crowdsourcing is an effective way to harness the human cognitive ability to process these machine-hard tasks. Thanks to public crowdsourcing platforms, e.g., Amazon Mechanical Turk and CrowdFlower, we can easily involve hundreds of thousands of ordinary workers (i.e., the crowd) to address these machine-hard tasks. In this tutorial, we will survey and synthesize a wide spectrum of existing studies on crowd-powered data mining. We first give an overview of crowdsourcing, and then summarize the fundamental techniques, including quality control, cost control, and latency control, which must be considered in crowdsourced data mining. Next we review crowd-powered data mining operations, including classification, clustering, pattern mining, outlier detection, knowledge base construction and enrichment. Finally, we provide the emerging challenges in crowdsourced data mining.

Breakthroughs in machine learning (ML) and artificial intelligence (AI) are making headlines daily. These breakthroughs are now available -- and increasingly important -- to every business, helping turn a vast, complex data landscape into useful business insights. The new CI&T and Google whitepaper: "CIO's Guide to Data Analytics & Machine Learning" is designed to help business decision makers understand and implement systems to get actionable, predictive insights from their data.

Machine Learning is enabling a transformation in the software industry without precedents. New Machine Learning powered predictive applications are performing jobs that were previously considered exclusive to highly skilled humans. We are already witnessing a new wave of innovation that is changing the face of all sectors of the economy. BigML is bringing the fourth edition of our Summer School in Machine Learning to Valencia. We will hold a two-day crash course ideal for business leaders, industry practitioners, advanced undergraduates, as well as graduate students, seeking a quick, practical, and hands-on introduction to Machine Learning to solve real-world problems.

Kaggle is a community and site for hosting machine learning competitions. Competitive machine learning can be a great way to develop and practice your skills, as well as demonstrate your capabilities. In this post, you will discover a simple 4-step process to get started and get good at competitive machine learning on Kaggle.

Stochastic gradient Markov chain Monte Carlo (SG-MCMC) has become increasingly popular for simulating posterior samples in large-scale Bayesian modeling. However, existing SG-MCMC schemes are not tailored to any specific probabilistic model, even a simple modification of the underlying dynamical system requires significant physical intuition. This paper presents the first meta-learning algorithm that allows automated design for the underlying continuous dynamics of an SG-MCMC sampler. The learned sampler generalizes Hamiltonian dynamics with state-dependent drift and diffusion, enabling fast traversal and efficient exploration of neural network energy landscapes. Experiments validate the proposed approach on both Bayesian fully connected neural network and Bayesian recurrent neural network tasks, showing that the learned sampler out-performs generic, hand-designed SG-MCMC algorithms, and generalizes to different datasets and larger architectures.

Machine learning is the science of getting computers to act without being explicitly programmed. In the past decade, machine learning has given us self-driving cars, practical speech recognition, effective web search, and a vastly improved understanding of the human genome. Machine learning is so pervasive today that you probably use it dozens of times a day without knowing it. Many researchers also think it is the best way to make progress towards human-level AI. In this class, you will learn about the most effective machine learning techniques, and gain practice implementing them and getting them to work for yourself.

Being a high schooler myself and having studied Machine Learning and Artificial Intelligence for a year now, I believe that there fails to exist a learning path in this field for High School students. This is my attempt to create one. Over the past few months, I've tried to spend a couple of hours every day understanding this field, be it watching Youtube videos or undertaking projects. I've been guided by older peers who've had far more experience than me, and now feel that I have ample experience to share my insights. All the information that I have compiled in this guide is intended for high schoolers wishing to excel in this up and coming field.

A couple weeks ago we discussed how to perform multi-label classification using Keras and deep learning. Today we are going to discuss a more advanced technique called multi-output classification. And how are you supposed to keep track of all these terms? You can even combine multi-label classification with multi-output classification so that each fully-connected head can predict multiple outputs! If this is starting to make your head spin, no worries -- I've designed today's tutorial to guide you through multiple output classification with Keras. It's actually quite easier than it sounds. That said, this is a more advanced deep learning technique we're covering today so if you have not already read my first post on Multi-label classification with Keras make sure you do that now. From there, you'll be prepared to train your network with multiple loss functions and obtain multiple outputs from the network.

Artificial intelligence is doing something that is human-like, doing things that appear human in terms of performance, although more recently, it's become more associated with some of the modern kinds of machine-learning-type approaches, using large amounts of data. You don't want to think about AI as being general intelligence like a human's. It works within a narrow domain and it tends to be applied in specific areas, but the term has become very widely used for anything where there's some kind of decision-making process done by computers. There are several different kinds of things that AI is able to do for language learning and literacy. One of the areas I think is key is the assessment of more open-ended responses, of things that beforehand were thought to be only at the level that could be assessed by humans.
