Reproducing Kernel Hilbert Space, Mercer's Theorem, Eigenfunctions, Nystr\"om Method, and Use of Kernels in Machine Learning: Tutorial and Survey

arXiv.org Machine Learning

This is a tutorial and survey paper on kernels, kernel methods, and related fields. We start with reviewing the history of kernels in functional analysis and machine learning. Then, Mercer kernel, Hilbert and Banach spaces, Reproducing Kernel Hilbert Space (RKHS), Mercer's theorem and its proof, frequently used kernels, kernel construction from distance metric, important classes of kernels (including bounded, integrally positive definite, universal, stationary, and characteristic kernels), kernel centering and normalization, and eigenfunctions are explained in detail. Then, we introduce types of use of kernels in machine learning including kernel methods (such as kernel support vector machines), kernel learning by semi-definite programming, Hilbert-Schmidt independence criterion, maximum mean discrepancy, kernel mean embedding, and kernel dimensionality reduction. We also cover rank and factorization of kernel matrix as well as the approximation of eigenfunctions and kernels using the Nystr{\"o}m method. This paper can be useful for various fields of science including machine learning, dimensionality reduction, functional analysis in mathematics, and mathematical physics in quantum mechanics.


Recreating an ML Master's degree with Online Courses

#artificialintelligence

A Bachelor's study usually takes six semesters; a Master's study takes four. But this is only an outline. I've witnessed people doing their BA in three semesters and some taking nine semesters. Sometimes there are so many exciting courses that you voluntarily stay longer to learn it all. Therefore, I've loosely structured the recreated curriculum into four semesters.


Welcome! You are invited to join a webinar: How to employ Automated Machine Learning to Predict the Best Quality Potato Chip/Crisp. After registering, you will receive a confirmation email about joining the webinar.

#artificialintelligence

We will show how a team of researchers applied JADBioโ€™s Automated Machine Learning (AutoML) platform to predict potatoes' susceptibility to bruising and also its potential for coloration during chip/crisp processing. The aim was to differentiate between potatoes that would be less prone to bruising from those that would more easily bruise during mechanical handling. Another goal was to successfully predict the potatoesโ€™ potential susceptibility to acrylamide formation during chip/crisp processing due to the Maillard reaction. In this webinar series, Aris Karanikas (Business Development Officer) and Vincenzo Lagani (VP of Bioinformatics) at JADBio will demonstrate the advanced capabilities of AutoML to assist researchers and agronomists in data analysis. They will explain how to apply the JADBio platform based on real-life agricultural case-studies. Artificial intelligence (AI) and application of machine learning models are currently trending in the agriculture industry, and you will learn how it can help you to make better analytic decisions and improve your data interpretation efficiency. By attending this webinar, you will discover: - How you can analyze and classify your potato samples, without extensive data science knowledge - Discover which specific features play a role in high quality potatoes, along with their relative strength as predictors - Understand how relevant sets of equivalent predictors can also affect the desired result - How to apply your model on all future potato samples - How AutoML can help the agriculture industry in more efficient seed production, breeding, and many other sectors of the industry Who is this Webinar for: - Researchers - Agronomists - Farmers and anyone who needs to discover how they can utilize machine learning to predict crop performance, without the need to learn data science or acquire programming skills. Take-away: All attendees will receive a fully functional monthly licence (free of charge) for JADBio AutoML


Computer Simulations

#artificialintelligence

About this Course 11,731 recent views Big data and artificial intelligence get most of the press about computational social science, but maybe the most complex aspect of it refers to using computational tools to explore and develop social science theory. This course shows how computer simulations are being used to explore the realm of what is theoretically possible. Computer simulations allow us to study why societies are the way they are, and to dream about the world we would like to live in. This can be as intuitive as playing a video game. Much like the well-known video game SimCity is used to build and manage an artificial city, we use agent-based models to grow and study artificial societies.

The Best Course for NLP with Deep Learning is Free

#artificialintelligence

Natural language processing (NLP), or NLP for short, is a branch of artificial intelligence that helps computers understand, interpret, and manipulate human language. It is broadly defined as the automatic manipulation of natural language, like speech and text, by software or technology. Natural language processing is a form of AI that is easy to understand and start using. It can also do a lot to help you in making better business decisions. In order to make your website worth your user's time, NLP can do help you a lot.


A Framework to Counteract Suboptimal User-Behaviors in Exploratory Learning Environments: an Application to MOOCs

arXiv.org Artificial Intelligence

While there is evidence that user-adaptive support can greatly enhance the effectiveness of educational systems, designing such support for exploratory learning environments (e.g., simulations) is still challenging due to the open-ended nature of their interaction. In particular, there is little a priori knowledge of which student's behaviors can be detrimental to learning in such environments. To address this problem, we focus on a data-driven user-modeling framework that uses logged interaction data to learn which behavioral or activity patterns should trigger help during interaction with a specific learning environment. This framework has been successfully used to provide adaptive support in interactive learning simulations. Here we present a novel application of this framework we are working on, namely to Massive Open Online Courses (MOOCs), a form of exploratory environment that could greatly benefit from adaptive support due to the large diversity of their users, but typically lack of such adaptation. We describe an experiment aimed at investigating the value of our framework to identify student's behaviors that can justify adapting to, and report some preliminary results.


Transfer Learning for NLP with TensorFlow Hub

#artificialintelligence

This is a hands-on project on transfer learning for natural language processing with TensorFlow and TF Hub. By the time you complete this project, you will be able to use pre-trained NLP text embedding models from TensorFlow Hub, perform transfer learning to fine-tune models on real-world data, build and evaluate multiple models for text classification with TensorFlow, and visualize model performance metrics with Tensorboard. In order to successfully complete this project, you should be competent in the Python programming language, be familiar with deep learning for Natural Language Processing (NLP), and have trained models with TensorFlow or and its Keras API. Note: This course works best for learners who are based in the North America region.

Artificial Intelligence (AI) In The Classroom

#artificialintelligence

AI is finally here and most of us are already actively using it in our day-to-day life. To prepare our future generation to harness these technologies, educators need to understand how they can use AI, use it to facilitate learning and solve real-world problems. The course is aimed at all educators who would like to use AI, irrespective of the topic which they teach. The course assumes no prior knowledge of AI and will start by introducing the basic concepts. It will then illustrate a number of fun exercises which can be used with the students, to help them understand these concepts.
