Data Dependency - Both VLA and WA are based on the premise that "data determines the upper limit" of capabilities [2]. - VLA relies on real-world multimodal data to train reasoning abilities, while WA requires a combination of real data and simulated data to enhance its capabilities [2]. - The industry is confused about the distinction between "data form" and "data essence," leading to misconceptions about the reliance on data [2]. Industry Misconceptions - The article emphasizes that the discussion should not focus on whether data is needed, but rather on how to efficiently utilize data [2]. - VLA and WA represent different methods of data collection and usage, with data remaining the core competitive advantage in autonomous driving until true artificial intelligence is realized [2]. Community and Resources - The "Autonomous Driving Knowledge Planet" community has over 4,000 members and aims to grow to nearly 10,000 in two years, providing a platform for technical exchange and sharing of knowledge in the autonomous driving field [4][10]. - The community offers resources such as learning routes, technical discussions, and access to industry experts, facilitating knowledge sharing among newcomers and advanced practitioners [4][11].
