KI-Gan vessel的医学影像识别
Ki-GAN@1zw
说明这个仓库主要完成了Ki-Gan的论文复现工作数据来源为:https://link.springer.com/chapter/10.1007/978-3-030-32239-7_31参考了以下的repo:
https://github.com/lee-zq/VesselSeg-Pytorch/tree/master
https://github.com/chenyilan/MICCAI19-Ki-GAN
结果展示
数据先经过python 代码进行数据增强,在经过matlab 代码得到光声数据。下面是两种传统算法重构之后的图像,左为时间反朔法,右边为DAS,由于左侧图像更为清晰,因此不同于论文中提到的,我在实现时用bformer中选取右侧图像作为输入
KEB结果,是一个32张图片的阵列
消融实验结果
结论
从消融实验的结果来看,和论文中存在很大差距,可能是数据的来源,又或者是在生成光声数据时没有能做到完全复现,同时关于作者的稀疏实验部分,由于并不知道到底是哪些通道的数据被set zero了,因此 ...

Towards unified robotics manipulation via object-centric policyHao Dong @Peking University
难点
机器人遇到的环境很复杂,很难用简单的组合策略进行控制
object-centric policy人交互的时候存在与物体之间的先验知识
哪个部分可以交互
往哪里运动可以实现功能项目解决的问题给机器人一个物体,可以预测出这个物体会产生怎么样的交互结果通过强化学习的方式给出trajectory
问题:
有些物体需要两只手才能拿起来 dual-arm collaboration affordance
多arm协作的时候动作空间很大,很难学习,解决方法,将问题变为一个串形任务,比如先学习affordance1,再学习affordance2
Understanding of Hierarchical Reinforcement Learning
Understanding of Hierarchical Reinforcement Learningmisunderstanding of on-policy and off-policy
reference: on-policy and off-policy RL
definition
on-policy: the learning is from the data on the target policy
off-policy: the learning is from the data off the target policy
之所以有这个问题是因为我自己没有很好的区分行为策略和目标策略
行为策略:行为策略是专门负责学习数据的获取,具有一定的随机性,总是有一定的概率选出潜在的最优动作
目标策略:目标策略借助行为策略收集到的样本以及策略提升方法提升自身性能,并最终成为最优策略
异策略有时候需要重要性采样,而同策略不需要重要性采样这是因为需要估计一个策略的价值,而这个策略的价值是由另一个策略的价值估计出来的,所以需要重要性采样

Q:在任意终端下使用autogptA:autogpt中的指令1python -m autogpt
实际上是讲autogpt作为一个模块来调用,想要全局调用更改pythonpath就可以,以win11为例,环境变量PYTHONPATH中添加1E:\\wily\\AUTO-GPT\
对于linux,可以在终端中1export PYTHONPATH=your_autogpt_path
也可以更改 /etc/profile 或者 ~/.bashrch 或者 ~/.bash_profile12vim /etc/profileexport PYTHONPATH=your_autogpt_path
