The Kernel Trick

#artificialintelligence

The goal of this writeup is to provide a high-level introduction to the "Kernel Trick" commonly used in classification algorithms such as Support Vector Machines (SVM) and Logistic Regression. My target audience are those who have had some basic experience with machine learning, yet are looking for an alternative introduction to kernel methods. We first examine an example that motivates the need for kernel methods. After an explanation about the "Kernel Trick", we finally apply kernels to improve classification results. The following code examples are in Python, and make heavy use of the sklearn, numpy, and scipy libraries.


A Review of Machine Learning Algorithms and Applications

#artificialintelligence

With the explosion of data generation, getting optimal solutions to data driven problems is increasingly becoming a challenge, if not impossible.The importance of machine learning algorithms, which can handle this burst of data and assist in intelligent decision making, is thus realised among data scientists. Within this category of machine learning algorithms, a special focus area is bio-inspired algorithms. This review article provides the readers some inputs on the advances in the domain of bio inspired algorithms and their potential applications across domains. It is increasingly being recognised that applications of intelligent bio-inspired algorithms are necessary for addressing highly complex problems to provide working solutions in time, especially with dynamic problem definitions, fluctuations in constraints, incomplete or imperfect information and limited computation capacity. More and more such intelligent algorithms are thus being explored for solving different complex problems. While some studies are exploring the application of these algorithms in a novel context, other studies are incrementally improving the algorithm itself.


Here's the best argument that computers could replace doctors, teachers, and even nannies The new new economy

#artificialintelligence

Artificial intelligence is improving rapidly, and a lot of people are worried that it will lead to massive job losses. In the past, technology mostly displaced workers doing routine tasks or manual labor. But as software becomes more sophisticated, there's a growing prospect that truck drivers, teachers, and perhaps even doctors could see their jobs replaced by a robot or a computer program. Ryan Avent is an economics correspondent for the Economist who has been thinking about the economics of automation for several years. He's a technology optimist -- he thinks software and robots really will massively boost economic productivity. But in a new book, he argues that this won't necessarily be good news for ordinary workers, since a glut of underemployed workers will make it harder to bargain for higher pay.

Airlines / Aviation # AI will soon fly over Pacific Ocean to San Francisco to save fuel By PTI 28 Aug, 2016, 16:43 hrs IST VIEW IN APP A senior DGCA official said using the new route would help in saving a lot of fuel as well as time. NEW DELHI: Saving significant fuel costs and time, Air India will soon start flying over the Pacific Ocean region for its lucrative direct services to San Francisco from here with aviation regulator DGCA approving the new rout. The regulatory nod comes as a boost... New Delhi: Thirty passengers aboard a stationary SpiceJet bus at Jabalpur airport had the fright of their lives on Saturday when an Air India aircraft seemed to be heading straight for them. Atrium Mortgage Investment Corp (TSE:AI) announced a monthly dividend on Monday, August 29th. Stockholders of record on Monday, September 12th will be paid a dividend of 0.0717 per share on Monday, September 12th.


Don't believe the hype: Three steps to guide the automation software decision process

#artificialintelligence

In general, the decision-making process regarding enterprise software has been difficult – and made more so by the inflated promises of slick marketing. But business process automation has proven difficult in particular, and for three particular reasons. The first is that providers over-sold the capabilities of the first generation of process automation solutions. Second, it's problematic to do an apples-to-apples comparison of automation products because no two are exactly alike. Finally, since most enterprise operations are in the early phase of automation adoption, case studies are hard to find.


Try This Free AI Tool By Google

#artificialintelligence

Google has just open-sourced its'Parsey McParseface' AI tool and it understands English Google has open-sourced its neural network framework, SyntaxNet to include new language parsing model for English, which it calls'Parsey McParseface.' This is a tool that developers can use to analyze English text. In other words, developers will be able to swindle with the underlying technology powering Google's powerful natural language software so that apps, voice assistants and robots can better comprehend what English-speaking users want. "One of the main problems that makes parsing so challenging is that human languages show remarkable levels of ambiguity," Google says in a blog post. "It is not uncommon for moderate length sentences--say 20 or 30 words in length--to have hundreds, thousands, or even tens of thousands of possible syntactic structures. A natural language parser must somehow search through all of these alternatives, and find the most plausible structure given the context."


The New Art of War: How artificial intelligence will meet drone warfare Latest News & Updates at Daily News & Analysis

#artificialintelligence

Famous Chinese military strategist Sun Tzu, who is credited as the author of the famous war strategy guidebook Art of War had said; "know thy self, know thy enemy. Those words were from the 5th century BC. The'art of war' in the 21st century is drastically different. So much so that Christopher Coker, professor at the London School of Economics and author of Warrior Geeks in a 2013 piece declared that technology, in fact, is now making man the weakest link in warfare. India is also now looking to get into the world of advanced drone warfare. New Delhi has shown renewed interest in buying some of the top US-made drones currently proving their worth for the American military around the world.


This New Technology Lets You 'Touch' Objects Onscreen--and Could Change CGI Forever

#artificialintelligence

Since the 1960s, the best way to simulate an object's motion in space has been 3D modeling. An integral element of the CGI process, it's a cumbersome, expensive endeavor, one that requires hundreds of hours of manpower, state-of-the-art technology, and ever-changing algorithms to produce even the shortest sequences. Interactive Dynamic Video, a new technology developed by MIT's Computer Science and Artificial Intelligence Lab (CSAIL), could significantly ameliorate the process. By calibrating the physical behavior of objects--analyzing vibrations in different frequencies in space--IDV can predict how objects will move in new situations, an unprecedented achievement in motion graphics. It could reduce the cost of the CGI process by eliminating the need for green screens.


Building a recommendation engine with AWS Data Pipeline, Elastic MapReduce and Spark

#artificialintelligence

From Google's advertisements to Amazon's product suggestions, recommendation engines are everywhere. As users of smart internet services, we've become so accustomed to seeing things we like. This blog post is an overview of how we built a product recommendation engine for Hubba. I'll start with an explanation of different types of recommenders and how we went about the selection process. Then I'll cover our AWS solution before diving into some implementation details. Content-based recommenders use discrete properties of an item, such as its tags.
