Abstract: In order to perform sentiment analysis on Weibo platform posts, a sentiment analysis model combining the LDA model and the machine learning model Snownlp is used to analyze posts data.

LDA-1B 要解决的不是“机器人能否模仿一个动作”，而是“机器人能否从大量质量参差、来源复杂、标注不完整的数据中持续学习世界如何变化”。过去很多机器人基础模型依赖行为克隆，也就是让模型看专家怎么做，然后学习在相似观察下输出相似动作。

We introduce LDA-1B, a robot foundation model that scales through universal embodied data ingestion by jointly learning dynamics, policy, and visual forecasting, assigning distinct roles to data of ...
