In the US, today is Inauguration Day, and as Joe Biden prepares to take the oath as our 46th president, it's worth taking a look back at the discussions four years ago. Back then, the "most tech-savvy" president exited as all eyes turned to Donald Trump trading in his Android Twitter machine for a secure device. We know how things went after that. Donald Trump isn't tweeting anymore (at least not from his main accounts), and the country is struggling through a pandemic. The outgoing president just saw his temporary YouTube ban extended and, in one of his last official acts, pardoned Anthony Levandowski for stealing self-driving car secrets from Google's subsidiary Waymo.

Interpol has warned of a new investment scam targeting users of mobile dating apps. As COVID-19 continues to severely restrict our daily lives and in many places, makes social interaction and meeting new people in person impossible, dating apps have experienced a surge in users. As the only possible method of anything akin to dating at the current time, scam artists have decided to capitalize on this trend in order to push an investment-based scam that deprives victims of their cash. According to Arkose Labs research, four million online dating fraud & abuse-related attacks were recorded in 2020, with many taking place through fake account registrations. On Tuesday, the International Criminal Police Organization (Interpol) said the agency had issued a "purple notice" -- the provision of data on criminal groups' methods, objects, devices, and concealment methods -- to 194 member countries.

Facebook has announced new improvements to its artificial intelligence (AI) technology that is used to generate descriptions of photos posted on the social network for visually impaired users. The technology, called automatic alternative text (AAT), was first introduced by Facebook in 2016 to improve the experience of visually impaired users. Up until then, visually impaired users who checked their Facebook newsfeed and came across an image would only hear the word "photo" and the name of the person who shared it. With AAT, visually impaired users have been able to hear things like "image may contain: three people, smiling, outdoors". Facebook said, with the latest iteration of AAT, the company has been able to expand the number of concepts that the AI technology can detect and identify in a photo, as well as provide more detailed descriptions to include activities, landmarks, food types, and types of animals, like "a selfie of two people, outdoors, the Leaning Tower of Pisa" instead of "an image of two people".

Social network analysis is the process of investigating social structures through the use of networks and graph theory. This article introduces data scientists to the theory of social networks, with a short introduction to graph theory and information spread. It dives into Python code with NetworkX constructing and implying social networks from real datasets. We'll start with a brief intro in network's basic components: nodes and edges. Nodes (A,B,C,D,E in the example) are usually representing entities in the network, and can hold self-properties (such as weight, size, position and any other attribute) and network-based properties (such as Degree- number of neighbours or Cluster- a connected component the node belongs to etc.).

It's difficult to say whether e-dating has weakened or boosted the pickup line game. It probably depends on who you ask. To get to the bottom of it, we ventured on over to Reddit to check out the general state of cheesy one-liners to be deployed in an online dating setting. And the results are, well … the results kinda speak for themselves. But as far as we can tell, pickup lines, like cockroaches after an apocalyptic event, have survived the shift to online dating and are doing just fine.

Parity is among a growing crop of startups promising organizations ways to develop, monitor, and fix their AI models.

Since Facebook acquired WhatsApp in 2014, users have wondered and worried about how much data would flow between the two platforms. Many of them experienced a rude awakening this week, as a new in-app notification raises awareness about a step WhatsApp actually took to share more with Facebook back in 2016. On Monday, WhatsApp updated its terms of use and privacy policy, primarily to expand on its practices around how WhatsApp business users can store their communications. A pop-up has been notifying users that as of February 8, the app's privacy policy will change and they must accept the terms to keep using the app. As part of that privacy policy refresh, WhatsApp also removed a passage about opting out of sharing certain data with Facebook: "If you are an existing user, you can choose not to have your WhatsApp account information shared with Facebook to improve your Facebook ads and products experiences."

In a surprise move, WhatsApp recently gave many of its users a difficult choice: they could either accept a revised privacy policy that explicit allowed the service to share information with parent company Facebook by February 8th, or decline and risk not being able to use the service at all. The company informed those users through an in-app notification which lays out the changes in very broad terms: the updates to the policy include "more information about WhatsApp's service and how we process your data, how businesses can use Facebook hosted services to store and manage their WhatsApp chats, [and] how we partner with Facebook to offer integrations across the Facebook Company Products." Upon further inspection, the updated policy makes clear that data collected by WhatsApp -- including user phone numbers, "transaction data, service-related information, information on how you interact with others (including businesses) when using our Services, mobile device information, your IP address" and more are subject to be shared with other properties owned and controlled by Facebook. "As part of the Facebook Companies, WhatsApp receives information from, and shares information (see here) with, the other Facebook Companies," the updated privacy policy reads. "We may use the information we receive from them, and they may use the information we share with them, to help operate, provide, improve, understand, customize, support, and market our Services and their offerings, including the Facebook Company Products."

The graph represents a network of 1,228 Twitter users whose tweets in the requested range contained "iiot ai", or who were replied to or mentioned in those tweets. The network was obtained from the NodeXL Graph Server on Friday, 25 December 2020 at 11:39 UTC. The requested start date was Friday, 25 December 2020 at 01:01 UTC and the maximum number of tweets (going backward in time) was 7,500. The tweets in the network were tweeted over the 2-day, 10-hour, 13-minute period from Tuesday, 22 December 2020 at 14:46 UTC to Friday, 25 December 2020 at 01:00 UTC. Additional tweets that were mentioned in this data set were also collected from prior time periods.
