Abstract
Point cloud data is widely used in 3D vision and perception, but its large-scale and high-dimensional characteristics bring challenges to data processing and storage. In order to solve this problem, an efficient point cloud data thinning model is proposed based on principal component analysis(PCA) and deep learning technology. Firstly, the dimensionality reduction combined with PCA can effectively reduce the redundancy of point cloud data, thus reducing the dimensionality and storage requirements of data. Secondly, through deep learning technology, we design a point cloud thinning model, which can further reduce the data density while retaining key information. This deep learning model has strong generalization ability and can adapt to the needs of different point cloud data sets and application scenarios. The experimental results show that the proposed model can reduce the data volume and keep the information integrity of the data better. This is of great significance for some applications that need efficient data management, such as 3D target detection and recognition.

  • Pretraining has recently greatly promoted the development of natural language processing (NLP)
  • We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
  • We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
  • The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
  • Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
