用户看的留存高，时长高，使用心流模型
2.2 心流模型
zh.wikipedia.org/wiki/%E5%BF… 心流的表现特征概括为六点(Csikszentmihalyi, 2002)，包括“强烈、集中的注意力“、”行动和意识的融合“、”能从容应对局面，完全控制自己的行为“、”自我意识的消解“、”时间的扭曲“以及”内在奖励，行动本身即是目的“

2.2.2 心流跟游戏相关 Reality is broken
Playing a game is the voluntary attempt to overcome unnecessary obstacles. http://93.174.95.29/_ads/0AA08A99395AC068DB6EAFDCA0DC947A
The Four Defining Traits of a Game
- Goal：一个具体的目标，可以让人集中注意力
- Rules：限制实现目标的因素，让人有creativity and foster strategic thinking和探索欲望
- Feedback system：告诉人与目标有多么接近，提供持续的动机（暗示一个承诺：目标是可以到达的）
- Voluntary participation：人接受goal和rule和feedback，并且要给人自由进入或者退出游戏，从而提供safe和pleasurable的感觉
Reality
- 1 UNNECESSARY OBSTACLES Compared with games, reality is too easy. Games challenge us with voluntary obstacles and help us put our personal strengths to better use Fix #1: Tackle unnecessary obstacles
- 2 EMOTIONAL ACTIVATION Compared with games, reality is depressing. Games focus our energy, with relentless optimism, on something we’re good at and enjoy. Fix #2: Activate extreme positive emotions
- 3 MORE SATISFYING WORK Compared with games, reality is unproductive. Games give us clearer missions and more satisfying, hands-on work. Fix #3: Do more satisfying work
- 4 BETTER HOPE OF SUCCESS Compared with games, reality is hopeless. Games eliminate our fear of failure and improve our chances for success. Fix #4: Find better hope of success
- 5 STRONGER SOCIAL CONNECTIVITY Compared with games, reality is disconnected. Games build stronger social bonds and lead to more active social networks. The more time we spend interacting within our social networks, the more likely we are to generate a subset of positive emotions known as “prosocial emotions.” Fix #5: Strengthen your social connectivity
- 6 EPIC SCALE Compared with games, reality is trivial. Games make us a part of something bigger and give epic meaning to our actions. Fix #6: Immerse yourself in epic scale
- 7 WHOLEHEARTED PARTICIPATION Compared with games, reality is hard to get into. Games motivate us to participate more fully in whatever we’re doing. Fix #7: Participate wholeheartedly wherever, whenever we can
- 8 MEANINGFUL REWARDS WHEN WE NEED THEM MOST Compared with games, reality is pointless and unrewarding. Games help us feel more rewarded for making our best effort. Fix #8: Seek meaningful rewards for making a better effort
- 9 MORE FUN WITH STRANGERS Compared with games, reality is lonely and isolating. Games help us band together and create powerful communities from scratch. Fix #9: Have more fun with strangers
- 10 HAPPINESS HACKS Compared with games, reality is hard to swallow. Games make it easier to take good advice and try out happier habits. Fix #10: Invent and adopt new happiness hacks
- 11 A SUSTAINABLE ENGAGEMENT ECONOMY Compared with games, reality is unsustainable. The gratifications we get from playing games are an infinitely renewable resource. Fix #11: Contribute to a sustainable engagement economy
- 12 MORE EPIC WINS Compared with games, reality is unambitious. Games help us define awe-inspiring goals and tackle seemingly impossible social missions together. Fix #12: Seek out more epic wins
- 13 TEN THOUSAND HOURS COLLABORATING Compared with games, reality is disorganized and divided. Games help us make a more concerted effort—and over time, they give us collaboration superpowers. Fix #13: Spend ten thousand hours collaborating
- 14 MASSIVELY MULTIPLAYER FORESIGHT Reality is stuck in the present. Games help us imagine and invent the future together. Fix #14: Develop massively multiplayer foresight
2.2.1 心流应用举例
举例：高留存应用
抖音，西瓜
Goals：愉悦，感觉开心，涨了见识 Rules：可能会对刷到的内容感觉不好，但是你只要继续刷就能刷到你想看的（但是如果持续是你想看的，可能会厌倦） Feedback systems：只要继续刷，就能看到不一样的生活，不一样的世界 Voluntary participation：刷视频，看视频不需要多少精力（看到不喜欢的需要过滤的精力），可以随时关掉，有安全感
2.3 怎么优化各个位置来，实现最佳的心流模型
核心：保证每隔一段消耗（动手刷，眼睛看标题和封面来确认是否点击）就有一个奖励（让人愉悦，让人开心，让人感动，让人涨知识） 消耗要合适，不能太费劲 奖励要合适，尽量不重复相同的奖励（或者重复有限的次数），防止边际效用递减
3 实现心流模型架构
3.1 行业推荐流程
收集上下文信息，收集用户画像 召回视频 组合召回的视频 精排视频 收集视频画像 规则处理（打散，强插，过滤，重排）
3.2 优化模型方案
- 直接上强化学习 怎么看视频，能保证看视频的时长最长，至于怎么组合，需要学习出来
- 规则系统 定义高回报召回和低回报召回（可以使用随机，为强化学习做探索用），已某种定义的间隔分发
4 当前可以实现的优化方案和计划
因为主行业推荐流程暂时不能更改，所以主要从召回 -> 规则 -> 精排去完善
