You need datasets to practice on when getting started with deep learning for natural language processing tasks. It is better to use small datasets that you can download quickly and do not take too long to fit models. Further, it is also helpful to use standard datasets that are well understood and widely used so that you can compare your results to see if you are making progress. In this post, you will discover a suite of standard datasets for natural language processing tasks that you can use when getting started with deep learning. I have tried to provide a mixture of datasets that are popular for use in academic papers that are modest in size.

Healthcare organizations need predictive analytics for providing quality healthcare and population health management. Building predictive models by applying machine learning algorithms is complex in the infrastructure-as-a-service or platform-as-as-a-service environment as it involves distributed computing. The emergence of predictive analytics in the healthcare industry has offered enormous opportunity to be able to predict the events in healthcare organization and other industries as well such as aerospace industry. Predictive analytics is a subfield of data science that deploys several multi-disciplinary fields such as statistical inference, machine learning, clustering, data visualization, and machine learning iteratively through the lifecycle of the data analytics. The stages can be defined as defining the problem statement for the organization, scope of the data analytics project, collection of big data, exploratory data analysis, data preparation, deployment of predictive models leveraging machine learning algorithms.

A new podcast series from the McKinsey Global Institute explores how technologies like automation, robotics, and artificial intelligence are shaping how we work, where we work, and the skills we need to work. The future of work is one of the hottest topics in 2017, with conflicting information from various experts leaving plenty of room for debate around what impact automation technology like artificial intelligence (AI) and robotics will have on jobs, skills, and wages. In the first episode of the New World of Work podcast from the McKinsey Global Institute--which is being featured in the McKinsey Podcast series--MGI chairman and director James Manyika speaks with senior editor Peter Gumbel about what these technologies are, how they will change work, and what new research says we can expect. This is our new series on work, the world of work, and the changing world of work. Today, for our first podcast on this issue, I'm with James Manyika, who is the chairman and director of the McKinsey Global Institute; he's also a senior partner at McKinsey and is based in the San Francisco office. James, this issue of work and the future of work is one that you have been looking at for some time, with work on automation and with the latest report on jobs, Jobs lost, jobs gained. Perhaps, you can start off by telling us about the broader issues, and which ones you're focusing on. James Manyika: Well, I think we're having an interesting time in our history and our economy around the future of work. It comes up in almost every conversation with students, workers, CEOs, and policymakers.

This course is the next logical step in my deep learning, data science, and machine learning series. I've done a lot of courses about deep learning, and I just released a course about unsupervised learning, where I talked about clustering and density estimation. So what do you get when you put these 2 together? In these course we'll start with some very basic stuff - principal components analysis (PCA), and a popular nonlinear dimensionality reduction technique known as t-SNE (t-distributed stochastic neighbor embedding). Next, we'll look at a special type of unsupervised neural network called the autoencoder.

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.

The area of online machine learning in big data streams covers algorithms that are (1) distributed and (2) work from data streams with only a limited possibility to store past data. The first requirement mostly concerns software architectures and efficient algorithms. The second one also imposes nontrivial theoretical restrictions on the modeling methods: In the data stream model, older data is no longer available to revise earlier suboptimal modeling decisions as the fresh data arrives. In this article, we provide an overview of distributed software architectures and libraries as well as machine learning models for online learning. We highlight the most important ideas for classification, regression, recommendation, and unsupervised modeling from streaming data, and we show how they are implemented in various distributed data stream processing systems. This article is a reference material and not a survey. We do not attempt to be comprehensive in describing all existing methods and solutions; rather, we give pointers to the most important resources in the field. All related sub-fields, online algorithms, online learning, and distributed data processing are hugely dominant in current research and development with conceptually new research results and software components emerging at the time of writing. In this article, we refer to several survey results, both for distributed data processing and for online machine learning. Compared to past surveys, our article is different because we discuss recommender systems in extended detail.

We study the problem of learning a latent variable model from a stream of data. Latent variable models are popular in practice because they can explain observed data in terms of unobserved concepts. These models have been traditionally studied in the offline setting. The online EM is arguably the most popular algorithm for learning latent variable models online. Although it is computationally efficient, it typically converges to a local optimum. In this work, we develop a new online learning algorithm for latent variable models, which we call SpectralLeader. SpectralLeader always converges to the global optimum, and we derive a $O(\sqrt{n})$ upper bound up to log factors on its $n$-step regret in the bag-of-words model. We show that SpectralLeader performs similarly to or better than the online EM with tuned hyper-parameters, in both synthetic and real-world experiments.

"AI is the new electricity" If you're a machine learning and ai enthusiast, you definitely must know this guy. He is best known for his machine learning course on coursera which, for many, has been the first step in understanding artificial intelligence(read my blog about it here). Andrew has been teaching at stanford ever since he got his Phd in 2002. He founded and led the google brain team which is considered as one of the most progressive ML/AI research organisations in the world. He also founded the popular massive open online course (MOOC) site coursera, which now has over a thousand courses taught by ivy league professors.

The value of bitcoin skyrocketed in 2017, and its rapid rise generated huge amounts of interest in it and other types of cryptocurrency. However, bitcoin is notoriously volatile, and a multitude of financial experts have advised people not to get involved, calling it a bubble that could burst at any moment. There are now fears that it already has. The I.F.O. is fuelled by eight electric engines, which is able to push the flying object to an estimated top speed of about 120mph.

In recent years, Convolutional Neural Networks (CNNs) have shown remarkable performance in many computer vision tasks such as object recognition and detection. However, complex training issues, such as "catastrophic forgetting" and hyper-parameter tuning, make incremental learning in CNNs a difficult challenge. In this paper, we propose a hierarchical deep neural network, with CNNs at multiple levels, and a corresponding training method for lifelong learning. The network grows in a tree-like manner to accommodate the new classes of data without losing the ability to identify the previously trained classes. The proposed network was tested on CIFAR-10 and CIFAR-100 datasets, and compared against the method of fine tuning specific layers of a conventional CNN. We obtained comparable accuracies and achieved 40% and 20% reduction in training effort in CIFAR-10 and CIFAR 100 respectively. The network was able to organize the incoming classes of data into feature-driven super-classes. Our model improves upon existing hierarchical CNN models by adding the capability of self-growth and also yields important observations on feature selective classification.
