How AI Protects PayPal's Payments and Performance The Official NVIDIA Blog

#artificialintelligence

With advances in machine learning and the deployments of neural networks, logistic regression-powered models are expanding their uses throughout PayPal. PayPal's deep learning system is able to filter out deceptive merchants and crack down on sales of illegal products. Kutsyy explained the machines can identify "why transactions fail, monitoring businesses more efficiently," avoiding the need to buy more hardware for problem solving.

How to Solve the New $1 Million Kaggle Problem - Home Value Estimates

@machinelearnbot

More specifically, I provide here high-level advice, rather than about selecting specific statistical models or algorithms, though I also discuss algorithm selection in the last section. If this is the case, an easy improvement consists of increasing value differences between adjacent homes, by boosting the importance of lot area and square footage in locations that have very homogeneous Zillow value estimates. Then for each individual home, compute an estimate based on the bin average, and other metrics such as recent sales price for neighboring homes, trend indicator for the bin in question (using time series analysis), and home features such as school rating, square footage, number of bedrooms, 2- or 3-car garage, lot area, view or not, fireplace(s), and when the home was built. With just a few (properly binned) features, a simple predictive algorithm such as HDT (Hidden Decision Trees - a combination of multiple decision trees and special regression) can work well, for homes in zipcodes (or buckets of zipcodes) with 200 homes with recent historical sales price.


What Artificial Intelligence Means for Markets & Investing

#artificialintelligence

Artificial intelligence and machine learning is suddenly all the rage, and for good reason. It is the future of this, and every other industry. If you've been paying attention to the evolution of technology over the past 2.6 million years, you knew it was coming. Wherever the bulk of the effort has been shouldered by human beings, we have always sought to replace us with technology that could do the job better, faster, more efficiently and, since the invention of capital, cheaper. It began with the most basic, brute force physical tasks and has progressively involved more nuanced, cognitive processes.


How Blockchains could transform Artificial Intelligence - Dataconomy

#artificialintelligence

In recent years, AI (artificial intelligence) researchers have finally cracked problems that they've worked on for decades, from Go to human-level speech recognition. A key piece was the ability to gather and learn on mountains of data, which pulled error rates past the success line. In short, big data has transformed AI, to an almost unreasonable level. Blockchain technology could transform AI too, in its own particular ways. Some applications of blockchains to AI are mundane, like audit trails on AI models.


Just How Smart Are Smart Machines?

#artificialintelligence

If popular culture is an accurate gauge of what's on the public's mind, it seems everyone has suddenly awakened to the threat of smart machines. Several recent films have featured robots with scary abilities to outthink and manipulate humans. In the economics literature, too, there has been a surge of concern about the potential for soaring unemployment as software becomes increasingly capable of decision making. Yet managers we talk to don't expect to see machines displacing knowledge workers anytime soon -- they expect computing technology to augment rather than replace the work of humans. In the face of a sprawling and fast-evolving set of opportunities, their challenge is figuring out what forms the augmentation should take.

UK Startup Takes On GPUs with Neural Network Accelerator

#artificialintelligence

AI startup Graphcore has emerged from stealth mode with the announcement of $30 million in initial Series A funding. The Bristol, UK-based company will use the cash infusion to complete development of its Intelligent Processing Unit (IPU), a custom-built chip aimed at machine learning workloads. The funding was led by Robert Bosch Venture Capital GmbH and Samsung Catalyst Fund; also joining were Amadeus Capital Partners, C4 Ventures, Draper Esprit plc, Foundation Capital and Pitango Venture Capital. The IPU has been under development at Graphcore for two years, with the first product slated to be released in the second half of 2017. It's designed to work across a range of machine learning application and is applicable to both training and inferencing neural networks.

SoftBank Group Corp.'s former Chief Operating Officer Nikesh Arora, whose 8 billion package topped the list, hails from India. Higher wages in Japan were typically earned by sticking around, thanks to rigid corporate promotion systems based on tenure. In the U.S., executives have reaped the benefits of a shift from cash to equity-based compensation tied to their companies' performance -- a change that sent pay packages spiraling in recent decades as the stock market soared. Interlocking stock ownership between companies listed on the Tokyo Stock Exchange fell to 16 percent in 2015 from 50 percent in 1990, according to data from Nomura Holdings Inc. Last year's biggest pay packages for Japan executives born in the country were Fanuc Corp. CEO Yoshiharu Inaba's 690 million and Sony Corp. CEO Kazuo Hirai's 513 million, data compiled by Bloomberg show.


Behavior I/O: Using Machine Learning to Empower Human Learning

#artificialintelligence

You can think of this virtuous cycle as "Behavior I/O:" In the consumer world, many companies like Fitbit (NYSE: FIT) and LinkedIn (NYSE: LNKD) learn from people's behavior to help train other people to behave better. Could you use machine learning to observe behavior of analysts, ultimately using those observations to improve how their colleagues use data? Even with such a rich corpus, there are still a lot of problems to solve in implementing a behavioral learning system that actually helps drive behavior. Before Alation, Satyen spent nearly a decade at Oracle, ultimately running the Financial Services Warehousing and Performance Management business where he helped customers get insights out of their systems.


Arimo Predictive Engine (tm) Shows Opportunity to Improve Investor Returns in Peer-to-Peer Lending - Arimo

#artificialintelligence

Random forest model using Lending Club public dataset shows opportunity to improve adjusted return by 2.75% Arimo recently performed a study using a public dataset provided by Lending Club with the goal of showing how machine learning could improve investor returns. The difference between adjusted NAR and the interest rate charged across an investor's portfolio (net of Lending Club fees) is the opportunity to improve return. We chose a random forest model for this task because they offer high classification performance when taking large numbers of features into account. We formulated this predictive task as a binary classification problem and trained the model on Lending Club's historical data of accepted loans to predict loans that are more likely to charge off (they are either actually charged off, default, or late).
