It is the world’s most popular video app. Our journalist received an inside business paper that provides new information about how the algorithm works.
How TikTok Reads Your Mind?
TikTok does not, technically, read your thoughts. However, TikTok has revealed that it uses an improved and more sophisticated algorithm. Your feed is analysed by this algorithm. The app keeps track of the videos you’ve liked and the ones you’ve watched. It pushes more videos similar to the ones you’ve liked to your ‘For You’ page. As a result, you will continue to watch and like similar videos.
You now understand how TikTok reads your mind through the app. While modern algorithms frequently push more similar videos on apps, how does this affect your thinking? Let me explain how TikTok affects your thinking.
Does TikTok Affect the Way You Think?
TikTok has no direct impact on your thoughts. However, it does have an impact on how you watch movies on the app. Because the algorithm forces you to watch videos with similar context, navigating it can be difficult. If you watch videos that negatively influence your thinking, the algorithm will push more of them into your feed. TikTok can thus influence your thinking in this way. Because we all spend so much time on the app, it will heavily influence your decisions.
There are four main goals for TikTok’s algorithm: 用户价值, 用户价值 (长期), 作者价值, and 平台价值, which the company translates as “user value,” “long-term user value,” “creator value,” and “platform value.”
That list of objectives is based on a candid and illuminating document for corporate employees, which reveals fresh facts about how the world’s most successful video app created such a fascinating — some would say addictive — product.
TikTok’s technical team in Beijing created the document, titled “TikTok Algo 101.” Hilary McQuaide, a corporate spokeswoman, acknowledged its validity and stated that it was designed to illustrate how the algorithm works to nontechnical personnel. The document provides a new level of detail about the dominant video app, revealing both the app’s mathematical core and insight into the company’s understanding of human nature — our tendencies toward boredom, our sensitivity to cultural cues — that helps explain why it’s so difficult to put down. The document also reveals the company’s seamless relationship with its Chinese parent company, ByteDance, at a time when the US Department of Commerce is preparing a report on whether TikTok poses a security risk.
If you’re one among the billion people (literally!) who use TikTok every month, you’re already familiar with the app as the key vehicle for young culture and online culture in general in 2021. It shows an endless stream of videos and, unlike the social media apps it is quickly displacing, functions as more of an entertainment platform than a way to communicate with friends.
It succeeded where previous short video applications failed because it made creation so simple, providing users with background music to dance to or memes to act out rather than requiring them to fill dead air. And, for many users who consume rather than create, the app is astonishingly effective at reading your interests and guiding you to one of its many “sides,” whether you’re interested in socialism, Excel tips, sex, conservative politics, or a certain celebrity. It’s astonishingly good at revealing people’s desires — “The TikTok Algorithm Knew My Sexuality Better Than I Did,” reads one of a series of headlines about people marvelling at the app’s X-ray of their inner lives.
TikTok has publicly disclosed the general outlines of its recommendation algorithm, stating that it considers criteria such as likes and comments, as well as video information such as subtitles, sounds, and hashtags. Outside analysts have also attempted to decipher its coding. According to a recent Wall Street Journal report, TikTok heavily relies on how long you spend watching each video to steer you toward more videos that will keep you scrolling, and that process can sometimes lead young viewers down dangerous rabbit holes, particularly toward content that promotes suicide or self-harm — problems that TikTok says it is working to address by aggressively deleting content that violates its terms of service.
The new document was handed to The New York Times on the condition of anonymity by a person who was allowed to read it but not share it. The user was bothered by the app’s promotion of “sad” content that could lead to self-harm.
According to the document, in order to achieve the company’s “ultimate goal” of increasing daily active users, it has chosen to optimise for two closely connected metrics in the stream of films it serves: “retention” — that is, whether a user returns — and “time spent.” The app urges you to stay as long as possible. The experience has been regarded as addictive at times, but it also evokes a common criticism of pop culture.
In a caustic 1998 article about “pseudoart,” playwright David Mamet remarked that “people are driven to summer movies because they are not satisfactory, and thus they give possibilities to repeat the compulsion.”
The TikTok document validates the worries of analysts who feel algorithmic suggestions pose a social threat.
“With this approach, watch time is critical. “The algorithm tries to get people addicted instead of giving them what they really want,” said Guillaume Chaslot, founder of Algo Transparency, a Paris-based group that has studied YouTube’s recommendation system and has a pessimistic view of the product’s impact on children in particular. At my request, Mr. Chaslot evaluated the TikTok document.
“I think it’s a ridiculous concept to allow TikTok’s algorithm direct our children’s lives,” he remarked. “With each video a child views, TikTok learns more about him.” The programme can determine his musical choices, physical attraction, depression, drug use, and a variety of other sensitive information in a few of hours. There is a strong possibility that some of this material will be utilised against him. It might be used to micro-target him or to increase his reliance on the platform.”
According to the document, watch time isn’t the only thing TikTok takes into account. The document provides a preliminary equation for scoring videos, in which a machine learning prediction and actual user behaviour are totaled up for each of three pieces of data: likes, comments, and playtime, as well as a signal that the video has been played:
Eplaytime X Vplaytime + Plike X Vlike + Pcomment X Vcomment + Pplay X Vplay
According to the document, “the recommender system assigns scores to all movies based on this equation and returns to viewers the videos with the highest scores.” “The equation provided in this document has been greatly simplified for brevity. The exact equation is far more difficult, but the logic is the same.”
The document explains in detail how the company modifies its system to detect and suppress “like bait” — videos designed to game the algorithm by explicitly asking people to like them — as well as how the company considers more nuanced questions.
“Some writers may include cultural references in their videos, which visitors can only better comprehend by watching more of the author’s videos.” As a result, the total value of a user watching all of those movies is greater than the sum of the values of watching each individual video,” the document states. “Another example: if a user enjoys a certain type of video but the app continues to show him the same type, he will quickly become bored and close the app.” In this case, the total value created by the user watching the same type of videos is lower than the total value created by watching each individual video, because repetition leads to boredom.”
“There are two solutions to this problem,” the text continues. “Make some assumptions and deconstruct the value into a value equation.” For example, to address repetitive exposure, we could add a value’same author seen,’ and to address boredom, we could add a negative value’same tag today.’ Other solutions, aside than the value equation, such as forced suggestion in users’ for u feed and dispersion, may also work. For example, boredom can be alleviated through dispersion.”
Another chart in the document says that “creator monetization” is one of the company’s aims, implying that TikTok may prefer videos that are profitable rather than just amusing.
Julian McAuley, a computer science professor at the University of California San Diego who also reviewed the document, said in an email that the paper was lacking in clarity about how TikTok makes predictions, but that its recommendation engine is “perfectly plausible, but typical stuff.” According to him, the company’s competitive advantage stems from combining machine learning with “fantastic volumes of data, highly engaged users, and a setting where users are amenable to consuming algorithmically recommended content (consider how few other settings have all of these characteristics!).” Not some sort of algorithm.
Mr. McAuley went on to say that he was perplexed as to why people were continuously asking him about TikTok.
“It appears that there is some perception (by the media? or the general public?) that they’ve cracked some magical code for recommendation, but most of what I’ve seen appears to be fairly normal,” he wrote.Indeed, the document goes a long way toward demystifying the kind of recommendation system that tech companies frequently present as impossible for critics and regulators to understand, but that typically focuses on features that any ordinary user can understand. For example, The Wall Street Journal’s examination of hacked Facebook papers demonstrated how Facebook’s choice to give more weight to comments aided the spread of contentious content. While the models are complex, the TikTok recommendation algorithm outlined in the document is not inherently sinister or incomprehensible.
However, the document makes it clear that TikTok has done nothing to break ties with its Chinese parent company, ByteDance, whose ownership became a flashpoint at the end of President Donald J. Trump’s administration in 2020, when he attempted to force the sale of TikTok to an American company allied with his administration, Oracle.
The TikTok record alludes inquiries to a designing director whose LinkedIn memoir says he deals with both TikTok and ByteDance’s comparative Chinese application, Douyin, offering a brief look at the leftover worldwide component of an inexorably isolated tech industry, the designing ability. As per LinkedIn, the designing chief went to Peking College, got a graduate degree in software engineering at Columbia College and worked for Facebook for a long time prior to coming to ByteDance in Beijing in 2017. The report is written in clear, however nonnative, English, and comes according to the viewpoint of the Chinese tech industry. It makes no references, for example, to equal American organizations like Facebook and Google, however incorporates a conversation of “if Toutiao/Kuaishou/Weibo have accomplished something almost identical, could we at any point send off similar procedure as they have done?”
TikTok’s improvement cycle, the archive says, is firmly entwined with the course of Douyin’s. The report at one direct alludes TikTok representatives toward the “Send off Interaction for Douyin Suggestion Procedure,” and connections to an inner organization record that it says is “a similar report for TikTok and Douyin.”
TikTok workers are additionally profoundly entwined into ByteDance’s biological system. They utilize a ByteDance item called Songbird, a corporate inner interchanges framework like Leeway however with forceful execution the executives highlights pointed toward driving workers to utilize the framework more. There is, for example, a realistic that lets you know whether you have performed activities — like opening messages — pretty much than your collaborators, as per screen captures I was given.
Worry about Chinese customer innovation is bipartisan in the US. President Trump’s chief request endeavoring to boycott the application in August 2020 cautioned that TikTok’s “information assortment takes steps to permit the Chinese Socialist Coalition admittance to Americans’ own and restrictive data.” The Chinese government could “construct dossiers of individual data for extortion, and direct corporate secret activities,” it said. That boycott slowed down in court and blurred after the official political decision. President Biden repealed the leader request, yet his organization then declared its own examination concerning security dangers presented by TikTok, with an anonymous senior organization official let correspondents know that China was “attempting to use advanced advancements and American information in manners that present unsuitable public safety gambles.”
In a messaged proclamation, Ms. That’s what McQuaide said “while there’s some shared trait in the code, the TikTok and Douyin applications are run totally independently, on isolated servers, and neither one of the codes contains client information.”
She additionally said, “TikTok has never given client information to the Chinese government, nor would we whenever inquired.”
TikTok, whose CEO lives in Singapore, employed a pile of very much associated American and European chiefs and security specialists as political strain strengthened under Mr. Trump. It says it has no proper central command. It has tried to calm American worries by putting away client information in the US, with a reinforcement in Singapore.
The American government’s security concerns come in two structures. The first, as Mr. Trump proposed in his chief request, is whether the tremendous store of information TikTok holds — about the confidential sexual cravings of enthusiasts of the application who could wind up becoming American public authorities, for example — ought to be seen as a public safety issue. There’s no proof the information has at any point been utilized like that, and TikTok is not really the main spot Americans share subtleties of their lives via online entertainment. The subsequent concern is whether TikTok edits politically touchy posts.
A report this year by Resident Lab, the network safety guard dog association in Toronto, recommended that both of these worries are, best case scenario, idle: It found no sign that TikTok was either controlling delicate points or communicating information to China.
Be that as it may, TikTok’s brief looks at individuals’ inward lives are strange. One more screen capture imparted to me shows that its substance arbitrators approach to recordings posted freely, yet additionally to content shipped off companions or transferred to the framework yet not shared, a distinction from applications like WhatsApp and Flag that give start to finish encryption.
The subsequent inquiry is whether the Chinese government could utilize the stage to spread promulgation. Subsequent to getting found editing a video censuring the mass detainment of minority Muslims in China, TikTok has permitted analysis of the nation’s administration. For example, the hashtag #whereispengshuai, a reference to the Chinese tennis star who blamed a top Chinese pioneer for rape, autocompletes in the framework, however TikTok recordings with that hashtag have not many perspectives. There is no autonomous approach to telling whether the organization is stifling the hunt, which has undeniably greater commitment on Twitter however also minimal on Instagram.
A few American investigators consider TikTok to be a significant danger; others view it as the sort of dumbfounded alarm that Americans presently moving toward middle age confronted when their folks cautioned them that assuming they shared subtleties of their lives via virtual entertainment, they’d never find a new line of work. Many, numerous different items, from informal organizations to banks and charge cards, gather more exact information on their clients. On the off chance that unfamiliar security administrations needed that information, they could most likely figure out how to get it from the shadowy business of information dealers.
“Going nuts about observation or restriction by TikTok is an interruption from the way that these issues are such a great deal greater than a particular organization or its Chinese proprietorship,” said Samm Sacks, an online protection strategy individual at the exploration association New America. “Regardless of whether TikTok were American-possessed, there is no regulation or guideline that keeps Beijing from purchasing its information on the open information specialist market.”
One thing that revealing this segment has reminded me: The threat that TikTok stances to American public safety seems, by all accounts, to be completely speculative, and relies upon your examination of both the U.S.- China relationship and the fate of innovation and culture. Be that as it may, the calculation’s grip on what keeps me snared — between stunt tennis shots, Turkish food recordings and the wide range of various things it’s sorted out I like to watch — represented an obvious risk to my capacity to complete this segment.
So there you have it: TikTok can read your mind. The app’s clever algorithm analyses all of the videos you watch and enjoy. TikTok, unlike other apps, collects data on the videos you watch.
