Support Vector Machines for dummies; A Simple Explanation - AYLIEN

#artificialintelligence

In this post, we are going to introduce you to the Support Vector Machine (SVM) machine learning algorithm. We will follow a similar process to our recent post Naive Bayes for Dummies; A Simple Explanation by keeping it short and not overly-technical. The aim is to give those of you who are new to machine learning a basic understanding of the key concepts of this algorithm. Support Vector Machines – What are they? A Support Vector Machine (SVM) is a supervised machine learning algorithm that can be employed for both classification and regression purposes. SVMs are more commonly used in classification problems and as such, this is what we will focus on in this post. SVMs are based on the idea of finding a hyperplane that best divides a dataset into two classes, as shown in the image below.


What Machine Learning Means for Search Ads in Australia

#artificialintelligence

Machine learning is advancing ad tech by leaps and bounds. At events in Melbourne and Sydney, Tris Southey, product manager for DoubleClick Search, explained how Google's Smart Bidding can help brands run more effective Search campaigns. Great chefs will tell you that cooking is an art--but it's also a learning experience. When you're a beginner, you gather ingredients and follow the recipe, step by step. After you become an expert chef, you adjust elements of the dish as you go, substituting or adding ingredients until it tastes to your liking.


Hold Dear the Lamp Light: Before the Tides Rose Up

WIRED

The year Jojo and I started eighth grade, the power plant officially cut electricity to two hours a day. We'd already been through years of brownouts, of flickering lights, blinking monitors, older ag drones without artificial neural networks rebooting in their stations and randomly launching to spray the fields again or overfeed the chickens. So when Public Works & Electric issued a message to all our devices telling us about its irregular hours of operation, no one was surprised. The message was full of obfuscating language, but anyone with a tide chart could spot the correlation. Anyone driving down the causeway to the airport, past the power plant, could see through its chain-link fence the turbines standing silent, tense as raised shoulders; the grounds swamped in seawater, the ebbing tide dragging out an iridescent Rorschach of petroleum.


Feliks Zemdegs sets new Rubik's Cube world record

Daily Mail - Science & tech

The incredible moment a man solves a Rubik's cube in less than FIVE SECONDS to set a new world record (as the previous champion sits next to him and grins through gritted teeth) Feliks Zemdegs, 20, solved the famous 1980s toy in just 4.73 seconds Previous world record set by Mats Valk, 20, who is sitting next to Mr Zemdegs Mr Zemdegs got ten seconds to inspect the Rubik's cube before he has to solve it Feliks Zemdegs, 20, solved the famous 1980s toy in just 4.73 seconds Mr Zemdegs got ten seconds to inspect the Rubik's cube before he has to solve it His hands move so fast the camera struggles to pick up his finger movements. He solves the puzzle in just 4.73 seconds. The previous world record was set by Mats Valk, 20, (right) is sat next to Mr Zemdegs as he breaks his record.

Singapore's 'city brain' project is groundbreaking -- but what about privacy?

#artificialintelligence

You've read about cities installing smart parking meters and noise- and air-quality sensors, but are you ready to embrace the idea of a city brain? The residents of Singapore are on track to do just that. Creating a centralized dashboard view of sensors deployed across a distributed network is nothing new, but it takes on a bigger -- perhaps ominous -- meaning when deployed across a major city. Many technologically advanced cities worldwide are exploring ways to build such comprehensive digital views for managing traffic and parking, monitoring water and air quality, and offering such citizen-facing services as web-based tools for interacting with government agencies. Some smart city experts call this system approach a "city brain" or, less glamorously, a "municipal backplane."


Japan based live chat & dating app Festar sees 53% successful match rate

#artificialintelligence

Tokyo, Japan – Ten months since the official release of Ginkan Inc.'s chat and dating app Festar, the app has seen high successful match rates with 53% of pairs from over 17,000 matches mutually liking each other and choosing to continue to talk after a 10 minute chat. Festar has ditched the dating app standard of picking based on appearances, and is proving just how important mutual interests and meaningful conversation are with thousands of users finding love and friendship through a live 10 minute chat. Festar is now available in 13 countries in English, Korean, and Japanese for both iOS and Android smartphones. How Festar Works: Unlike many dating apps that make users search for a partner, Festar starts by automatically connecting people for a 10 minute real time chat. Users are matched based on mutual interests and hobbies, instead of swiping and searching by looks or social status.


Fast Stability Scanning for Future Grid Scenario Analysis

arXiv.org Machine Learning

Future grid scenario analysis requires a major departure from conventional power system planning, where only a handful of most critical conditions is typically analyzed. To capture the inter-seasonal variations in renewable generation of a future grid scenario necessitates the use of computationally intensive time-series analysis. In this paper, we propose a planning framework for fast stability scanning of future grid scenarios using a novel feature selection algorithm and a novel self-adaptive PSO-k-means clustering algorithm. To achieve the computational speed-up, the stability analysis is performed only on small number of representative cluster centroids instead of on the full set of operating conditions. As a case study, we perform small-signal stability and steady-state voltage stability scanning of a simplified model of the Australian National Electricity Market with significant penetration of renewable generation. The simulation results show the effectiveness of the proposed approach. Compared to an exhaustive time series scanning, the proposed framework reduced the computational burden up to ten times, with an acceptable level of accuracy.


TrademarkVision uses machine learning to make finding logos as easy as a reverse image search

#artificialintelligence

A company's logo is an important part of its identity, but the processes behind defining, registering, and protecting these trademarks is a convoluted and rather archaic one. A startup called TrademarkVision aims to simplify it by replacing that laborious and arcane process with what amounts to a machine-learning-powered reverse image search. This isn't in some lab, either: the EU just switched their whole image trademark system over to it. Most people probably haven't had to do many trademark and logo searches. Well, why don't you take the USPTO's version for a spin so you know what it's like? Try to find the Nike "Swoosh" or something.


Book: Machine Learning Algorithms From Scratch

@machinelearnbot

You must understand algorithms to get good at machine learning. The problem is that they are only ever explained using Math. In this mega Ebook written in the friendly Machine Learning Mastery style that you're used to, finally cut through the math and learn exactly how machine learning algorithms work. Using clear explanations, simple pure Python code (no libraries!) and step-by-step tutorials you will discover how to load and prepare data, evaluate model skill, and implement a suite of linear, nonlinear and ensemble machine learning algorithms from scratch. I live in Australia with my wife and son and love to write and code.


Brain tests predict children's futures

BBC News

Brain tests at the age of three appear to predict a child's future chance of success in life, say researchers. Low cognitive test scores for skills like language indicate less developed brains, possibly caused by too little stimulation in early life, they say. These youngsters are more likely to become criminals, dependent on welfare or chronically ill unless they are given support later on, they add. Their study in New Zealand appears in the journal, Nature Human Behaviour. The US researchers from Duke University say the findings highlight the importance of early life experiences and interventions to support vulnerable youngsters.
