看了这么多开源项目，推荐复现这几个VLA方法～

Core Viewpoint - The article emphasizes the increasing demand for VLA (Variable Latent Action) algorithms in the industry, highlighting the challenges associated with data collection and model training, which are critical for successful implementation in real-world applications [1][2][3]. Group 1: VLA Algorithm Demand and Challenges - There is a significant demand for VLA algorithms, as evidenced by numerous job postings and the increasing number of related research papers [1]. - Many practitioners express frustration over the difficulties in tuning VLA algorithms and the complexities involved in data collection [2]. - The reliance on real machine data for effective VLA model training poses challenges, as the data collected often proves to be inadequate for practical applications [3][8]. Group 2: Data Collection and Training - Data collection methods for VLA primarily include imitation learning and reinforcement learning, with a focus on remote operation and VR technologies [10]. - Effective data collection and ensuring high-quality data are crucial, particularly in the context of real-to-sim-to-real (real2sim2real) methodologies [10]. - Training VLA models typically requires simulation debugging, especially when real machine data is insufficient, with frameworks like Mujoco and Isaac Gym being essential for this process [11]. Group 3: Model Deployment and Optimization - After training, VLA models often require optimization techniques such as quantization and distillation to reduce parameter size while maintaining performance [12]. - The deployment of VLA models on edge devices presents challenges due to their large parameter sizes, necessitating lightweight operations [12]. - The article discusses the importance of fine-tuning models and the various tricks involved in training complex models like π0 and π0.5, which require significant expertise [11][8]. Group 4: Educational Initiatives - The article introduces a practical course aimed at helping individuals learn about VLA, covering topics such as hardware, data collection, algorithm training, and model deployment [13][17]. - The course is designed to address the rapid advancements in VLA technology and aims to equip participants with hands-on experience and knowledge [13][18]. - It includes a comprehensive curriculum that spans various aspects of VLA, from foundational concepts to advanced deployment techniques [19][20][21].
