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。

First, the cost of healthcare. The exponential increase in cost stems partiallyfrom the need for highly trained staff (PhDs, MDs, nurses, etc)—especially as the cost of skilled labor is growing far faster than inflation. As AI becomes increasingly able to function as a technical expert, there are opportunities to extend the abilities of our existin... See more

线性资本还在内部组成了一个更为年轻、能够快速反应的Bolt投资三人小组。他们负责在具体投资实践中做到三点——

第一,更灵活的投资额度。线性资本投资的典型目标范围是 300 万至 1000 万美元,对数额更大或更小的支票规模可以灵活调整。

第二,更快的决策速度。通过与创始团队的 3-4 次会议,原则上两周内做出决策,整体执行过程不超过一个月。

第三,更友好的条款。承诺提供匹配市场惯例基础上最简洁的条款。

一言以蔽之,“更轻,更快,更灵活”。

Language is a richer form of supervision than classical closed-set labels.

There is a broad middle of more-or-less commodity, more-or-less undifferentiated choices that depend on distribution and aggregation to be chosen.
