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。

3. I think this will most likely be the last cycle of cryptocurrencies. Because last cycle Bitcoin went from about 1200 to 20 000, it increased about 20 times, and this cycle from 20 000 to 60 000, it increased 3 times. The increase is much smaller than in the previous cycle. I think it is very likely that cryptocurrencies will trade like Nasdaq in... See more

9. 85% of the DAOs tracked by Chainalysis have their treasury in a single asset. USDC is more preferred than DAI for DAOs handling stablecoins.

The first is, LLMs generally will lose when they get displaced by a new and better technology.

In the aftermath of the 2016 Presidential election, these attitudes radically shifted. For different reasons, both sides of the political spectrum began to immensely distrust the platform monopolies. The algorithmically curated streams that had once seemed so futuristic suddenly became Orwellian. Today, it’s not only acceptable to move more of your... See more

Unity和Unreal两款游戏引擎都有超过二十年的发展历程,都包含了各种复杂的工具和功能。渲染,动画工具,脚本,profilers,DCC导入工具,地形,物理,网络,音频,VR,过场动画,版本控制集成等。就功能规格而言,Unity和Unreal无疑是目前功能最丰富和第二丰富的游戏引擎。
