StratLearner: Learning a Strategy for Misinformation Prevention in Social Networks
Given a combinatorial optimization problem taking an input, can we learn a strategy to solve it from the examples of input-solution pairs without knowing its objective function? In this paper, we consider such a setting and study the misinformation prevention problem. Given the examples of attacker-protector pairs, our goal is to learn a strategy to compute protectors against future attackers, without the need of knowing the underlying diffusion model. To this end, we design a structured prediction framework, where the main idea is to parameterize the scoring function using random features constructed through distance functions on randomly sampled subgraphs, which leads to a kernelized scoring function with weights learnable via the large margin method. Evidenced by experiments, our method can produce near-optimal protectors without using any information of the diffusion model, and it outperforms other possible graph-based and learning-based methods by an evident margin.
AI's Latest Breakthrough Will Transform Learning--Here Are 5 Ways
The Fourth Industrial Revolution just took a huge step forward, thanks to a breakthrough artificial intelligence (AI) model that can learn virtually anything about the world -- and produce the content to tell us about it. The AI program is GPT-3 by OpenAI, which started out as a language model to predict the next word in a sentence and has vastly exceeded that capability. Now, drawing from voluminous data -- essentially all of Wikipedia, links from Reddit, and other Internet content -- GPT-3 has shown it can also compose text that is virtually indistinguishable from human-generated content. Asger Alstrup Palm, Area9's chief technology officer, explained that GPT-3 was tasked with testing the "scaling hypothesis" -- to see if a bigger model with ever-increasing amounts of information would lead to better performance. Although it's too early to call the scaling hypothesis proven, there are some strong indications that this is, indeed, the case. Further validating the potential of GPT-3, Microsoft recently announced it will exclusively license the model from OpenAI, with the intention of developing and delivering AI solutions for customers and creating new solutions using natural language generation.
Early Prime Day deal drops 3rd-gen Echo Dot to $20 (when you buy two)
Amazon announced that it's annual Prime Day shopping event would be on October 13 and 14 this year, but we're already starting to see Prime-exclusive deals available. One of them knocks the 3rd-generation Echo Dot to its lowest price ever -- only $20 -- when you buy two of them and use the code DOTPRIME2PK at checkout. That means you'll spend a total of $40 for two Echo Dots, which is $10 less than the normal price and $2 less than their 2019 Black Friday sale price. Remember -- this is an early Prime Day deal, so you must be an Amazon Prime member to get the savings. The company continues to offer 30-day free trials to new Prime subscribers, so you can sign up and take advantage of this deal as well as be all set for Prime Day when it rolls around in about two weeks. It's also worth calling out that the Echo Dots in this deal are the previous models.
Video streaming device leader Roku debuts new soundbar, player and Roku Channel app
The newest Roku products include a streaming device promising improved video delivery throughout the home, a smaller soundbar that also streams, and an updated mobile app for viewing on the go. The nation's leading streaming platform, Roku said it had about 43 million monthly active accounts at the end of June 2020. Research firm eMarketer estimates Roku captures about 33% of U.S. internet users and 47% of connected TV users. Roku's lineup of devices includes the Roku Express ($29.99) and Roku Streaming Stick ($49.99). But its marquee standalone player โ it also markets Roku TVs with built-in streaming capability โ is the Roku Ultra ($99.99).
How Data is Redefining A&R's Role In The Modern Music Industry - Hypebot
Although A&Rs are still looking for the same qualities in an artist as they were fifty years ago, what they're looking for in that same artist's data โ and they way they're looking for โ it has changed dramatically. Editor's Note: Tommaso Rocchi is a 2020 Master of Arts graduate of The Global Entertainment and Music Business program at Berklee College of Music in Valencia, Spain. Data-driven A&R has been a buzzword for quite some time in the music industry, but also one of its most guarded secrets. Even before the acquisition of Sodatone by Warner Music Group, major and big indie record labels started to switch their mindsets and focus on the advantages of a data-driven approach. Compared to the classic "gut-feeling" expertise of a senior A&R, data analysis allows today's A&Rs to validate their intuition and justify talent acquisition with predictive modeling.
HR by Spreadsheet vs. HR by Algorithm
"โฆIn many organizations, the human resource department is responsible for many strategic tasks from managing the hiring to [the] termination of employee[s], for example monitoring of employees' at all the levels, handling payroll, managing employee[s'] benefits and so on. To make this work easier[,] organizations across the world are investing in HR automation [to] [carry] out the best human capital decision[s]โฆ" I know what you're thinking: "โฆmy company's board of directors is too visually impaired to consider what kind of impact these new-flanged capabilities will have on the company to actually consider them-- let alone implement themโฆ" but you would be wrong to think this way; because the change is not only already happening, but it is accelerating. While it is true that some companies have not fully considered implementing a complete, top-to-bottom HR automation strategy -- largely because such a thing is still too abstract a problem and a not-so-clear-opportunity right now -- news like Amazon's drive to automate hiring and onboarding for its hourly warehouse workers will not stay secret for long. Do not kid yourselves, while corporate boards are not known for being bastions of innovation and forward-thinking, they know it's possible -- even if they are unable to see its affect on the corporation's current business -- at least, not yet, anyway.

TCL 6-Series TV Review (2020): It's Our Favorite TV, Again
Someday, there will be a reason to spend more than $1,000 on a TV. For now, save your money and buy the new TCL 6-Series. For the third year in a row, the $650, 55-inch model is our favorite TV--where beautiful picture quality and a usable Roku interface meet a reasonable price. It has better picture than TVs that cost hundreds of dollars more, Roku OS built in, and even Chromecast for showing slideshows on the big screen. You can spend double the money for a slightly better-looking OLED TV, but this quantum dot, Mini-LED TCL is nearly as good--and comes with a better interface.
