陌生人社交痛点:1)供给不足,男女比大概为4:6,单个女生同一时间跟个别高质量男生社交,很多男生得不到社交资源;2) 匹配效率低下,匹配之后很难破冰,匹配后发生聊天的概率只有50%,女生回复的还要腰斩,男生发消息后女生回复比例是40%,女生发消息后男生回复的比例是90%;3)流量分配失衡,80%的社交资源掌握在20%的用户手中,特别是长相好看的

Soul原有解法:1)多元化玩法、构建优质内容创作者生态;2)基于兴趣的匹配系统、丰富画像标签体系、去中心化、去颜值化;3)弱化LBS社交、推荐系统兼顾长尾群体

Soul+AI的解法:1)AI虚拟人,承接得不到社交资源的男性的需求,支持多模态交互、拟人化程度高兼具工具属性、具备人设/形象/声音、AI自主运营高质内容,2)建立用户的AI数字分身代理,解决效

We assemble a dataset from 22 different robots collected through a collaboration between 21 institutions, demonstrating 527 skills (160266 tasks). We show that a high-capacity model trained on this data, which we call RT-X, exhibits positive transfer and improves the capabilities of multiple robots by leveraging experience from other platforms.

整个sim-to-real过程如图4所示,共分为四步:

(1)识别出机器人的物理参数,并对机器人进行刚体运动学/动力学建模;

(2)收集真实的关节电机执行数据,训练一个Actuator Net;

(3)在仿真中,利用Actuator Net建模关节电机,并结合第一步中的刚体运动学/动力学建模,进行强化学习;

(4)将第3步中训练得到的策略部署到真机上。
