Twitter To Study Harms Its Algorithm Causes

To fix a problem, first you have to admit there is one. 

Kudos to Twitter. JL 

Rachel Sandler reports in Forbes:

Social media face increasing scrutiny for their role in spreading dangerous conspiracy theories and enabling harassment. Twitter’s Responsible Machine Learning Initiative will release reports analyzing possible racial and gender bias in its image cropping algorithm, “a fairness assessment of our Home timeline recommendations across racial subgroups” and “an analysis of content recommendations for different political ideologies across seven countries.” Twitter’s tacit acknowledgement that its algorithms might be harmful to users and society at large contrasts with Facebook’s defenses of its recommendation algorithms.

Twitter said Wednesday it will study whether its machine-learning technology causes unintentional harm, a move that comes as social media companies face increasing scrutiny for their role in spreading dangerous conspiracy theories and enabling harassment. 

Algorithmic fairness initiative

  • In the coming months, Twitter’s Responsible Machine Learning Initiative will release reports analyzing possible racial and gender bias in its image cropping algorithm, “a fairness assessment of our Home timeline recommendations across racial subgroups” and “an analysis of content recommendations for different political ideologies across seven countries.”
  • After Twitter’s image algorithm was criticized last year for focusing on white faces over darker ones, the company maintained that its tests haven’t shown any racial or gender bias, though in the aftermath it announced features giving more users more control over images because ”we recognize that the way we automatically crop photos means there is a potential for harm.”
  • Twitter said the results from the reports may inform changes to the platform, new guidelines for how it designs certain products and “heightened awareness” around ethical machine learning. 

Crucial quote

“When Twitter uses ML, it can impact hundreds of millions of Tweets per day and sometimes, the way a system was designed to help could start to behave differently than was intended,” the company said. “These subtle shifts can then start to impact the people using Twitter and we want to make sure we’re studying those changes and using them to build a better product.”

Key background

The Twitter initiative comes as social media companies face accusations their algorithms are responsible for increasing polarization, echo chambers, misinformation and online radicalization. Twitter in particular has been criticized for not doing enough to combat harassment. Former New York Times columnist Charlie Wetzel argued in his newsletter, “Galaxy Brain,” this week that Twitter’s Trending section siphons the entire internet’s attention onto single users, leading to disproportionate outrage and the appearance of a widespread “cancel culture.” CEO Jack Dorsey has previously said he wants to see a future where users can choose which algorithm they want to use inside an App Store-like interface, instead of relying on one algorithm made by Twitter.

Tangent

Twitter’s tacit acknowledgement that its algorithms might be harmful to users and society at large contrasts with Facebook’s defenses of its recommendation algorithms. In a Medium post last month, Vice President of Global Affairs Nick Clegg argued that Facebook doesn’t have a commercial interest in amplifying extreme content, and that the platform isn’t solely responsible for increasing political polarization because individual choices also impact what users see on their News Feeds. “We need to look at ourselves in the mirror, and not wrap ourselves in the false comfort that we have simply been manipulated by machines all along,” he said.

"Finance代写 是信用货币出现后形成的经济范畴。它和信用有两个概念不一样:
1)金融没有实物借贷,具体指货币资金的融资(狭义的金融),挺多人除了通过借钱来融资,还通过发行股票来融资资金。
2)信用是指所有货币的贷款,而金融具体是指信用货币的融资。挺多人之所以要 创作一个除了“信用”以外的新概念来指货币的信用,是为了概括一种新的经济现象;信贷和currency circulation这两个经济过程紧密结合在一起。金融最大的特别的地方是银行信用,银行信用可以创造货币,可以制服货币。银行信贷是金融的核心,它可以创作和减少货币。
