Optimizing Kernel Machines using Deep Learning

arXiv.org Machine Learning

Building highly non-linear and non-parametric models is central to several state-of-the-art machine learning systems. Kernel methods form an important class of techniques that induce a reproducing kernel Hilbert space (RKHS) for inferring non-linear models through the construction of similarity functions from data. These methods are particularly preferred in cases where the training data sizes are limited and when prior knowledge of the data similarities is available. Despite their usefulness, they are limited by the computational complexity and their inability to support end-to-end learning with a task-specific objective. On the other hand, deep neural networks have become the de facto solution for end-to-end inference in several learning paradigms. In this article, we explore the idea of using deep architectures to perform kernel machine optimization, for both computational efficiency and end-to-end inferencing. To this end, we develop the DKMO (Deep Kernel Machine Optimization) framework, that creates an ensemble of dense embeddings using Nystrom kernel approximations and utilizes deep learning to generate task-specific representations through the fusion of the embeddings. Intuitively, the filters of the network are trained to fuse information from an ensemble of linear subspaces in the RKHS. Furthermore, we introduce the kernel dropout regularization to enable improved training convergence. Finally, we extend this framework to the multiple kernel case, by coupling a global fusion layer with pre-trained deep kernel machines for each of the constituent kernels. Using case studies with limited training data, and lack of explicit feature sources, we demonstrate the effectiveness of our framework over conventional model inferencing techniques.


On Optimal Generalizability in Parametric Learning

arXiv.org Machine Learning

We consider the parametric learning problem, where the objective of the learner is determined by a parametric loss function. Employing empirical risk minimization with possibly regularization, the inferred parameter vector will be biased toward the training samples. Such bias is measured by the cross validation procedure in practice where the data set is partitioned into a training set used for training and a validation set, which is not used in training and is left to measure the out-of-sample performance. A classical cross validation strategy is the leave-one-out cross validation (LOOCV) where one sample is left out for validation and training is done on the rest of the samples that are presented to the learner, and this process is repeated on all of the samples. LOOCV is rarely used in practice due to the high computational complexity. In this paper, we first develop a computationally efficient approximate LOOCV (ALOOCV) and provide theoretical guarantees for its performance. Then we use ALOOCV to provide an optimization algorithm for finding the regularizer in the empirical risk minimization framework. In our numerical experiments, we illustrate the accuracy and efficiency of ALOOCV as well as our proposed framework for the optimization of the regularizer.


[D] Research topic for a high school student โ€ข r/MachineLearning

@machinelearnbot

I'm practicing explaining ML concepts, so, experts, please correct me if any of my points are incorrect or misleading. For example, I was reading an example of regression analysis where the factors such as cylinders, displacement, horsepower affect the mpg of a car. The topic would touch on how many of these factors, or neurons is too much. It seems like you may be conflating features, data about what you're observing that you give as inputs to your model, such as "cylinders, displacement, horsepower", and neurons, which are fine-tuned by training to make up the function you're trying to learn. Maybe I can help you by giving a few reasons people don't just keep increasing the number of neurons.


Talks begin to rewrite rules protecting students from fraud

FOX News

Education Department officials opened formal negotiations on Monday to rewrite federal rules meant to protect students from fraud by colleges and universities. The talks with university representative and student advocates are taking place as the department faces criticism for delaying consideration of tens of thousands of loan forgiveness claims from students who say they were defrauded by for-profit colleges. The 1994 rule, known as borrower defense, allowed loan forgiveness if it was determined that the college had deceived them. But the rule was rarely used until the demise of Corinthian and ITT Tech for-profit chains several years ago, when thousands of students flooded the department with requests to cancel their loans. In 2016, the Obama administration passed revisions to the rule, which clarified the process and added protections for students.


Artificial Intelligence, Machine learning and Deep learning - These Are The Differences, Similarity And Their Integrity

#artificialintelligence

Regular articles on Artificial Intelligence (AI), Machine Learning and Deep Learning appear in the media. Some commentators use these terms synonymously. However, although AI, machine learning, and deep learning are often closely intertwined, they are based on completely different technologies and have their unique attributes. Artificial Intelligence โ€“ sounds quite futuristic or even science fiction, this is because this topic has been appearing in the media for over 60 years. Until recently, however, we lacked the necessary prerequisites to apply the resources required for complex AI algorithms completely.


Berkeley startup to train robots like puppets

@machinelearnbot

Robots today must be programmed by writing computer code, but imagine donning a VR headset and virtually guiding a robot through a task, like you would move the arms of a puppet, and then letting the robot take it from there. That's the vision of Pieter Abbeel, a professor of electrical engineering and computer science at the University of California, Berkeley, and his students, Peter Chen, Rocky Duan and Tianhao Zhang, who have launched a startup, Embodied Intelligence Inc., to use the latest techniques of deep reinforcement learning and artificial intelligence to make industrial robots easily teachable. "Right now, if you want to set up a robot, you program that robot to do what you want it to do, which takes a lot of time and a lot of expertise," said Abbeel, who is currently on leave to turn his vision into reality. "With our advances in machine learning, we can write a piece of software once -- machine learning code that enables the robot to learn -- and then when the robot needs to be equipped with a new skill, we simply provide new data." The "data" is training, much like you'd train a human worker, though with the added dimension of virtual reality.


Artificial Intelligence Will Automate Business Processes - DZone AI

Prior to founding CognitiveScale, Matt was the leader of Watson Labs for IBM, and as such he is well versed on cognitive computing and the superconvergence of cloud computing, big data, and artificial intelligence, and how these technologies are disrupting every business process and industry. Q: What are the keys to a successful AI strategy? A: It's a more complex lifecycle than clients may think. We begin by mapping how the AI lifecycle looks and how it fits within the SDLC. We discuss what kind of problems you can solve and how to understand the complexity of the problems we are solving.


Is Deep Learning "Software 2.0"? โ€“ Intuition Machine โ€“ Medium

#artificialintelligence

Andrej Karpathy has an article "Software 2.0" that makes the argument that Neural Networks (or Deep Learning) is a new kind of software. I do agree that there indeed a trend towards "teachable machines" as opposed to the more conventional programmable machines, however I do have an issue with some of the benefits that Karpathy mentions to back-up his thesis. Certainly Deep Learning is already eating the Machine Learning world with advances across the board. Karpathy mentions several well known ones: visual recognition, speech recognition, speech synthesis, machine translation, robotics and games. This frames his argument about the sea change in computing and perhaps its time to think about a new kind of software (I guess the kind that you teach like a dog instead of programming).


Jaron Lanier: 'The solution is to double down on being human'

The Guardian

Jaron Lanier has written a book about virtual reality, a phrase he coined and a concept he did much to invent. It has the heady title Dawn of the New Everything. But it's also a tale of his growing up and when you read it, what you really want to talk to him about is parenting. Lanier is 57, but his childhood as he describes it was so sad and so creative and so extreme, it makes him almost seem fated to pursue alternative worlds. Lanier's parents met in New York.
