ULIP is a Model-agnostic Multimodal Pre-training Framework, which can leverage information from other modalities (Images, Language) to improve the ability to understand 3D data without introducing any extra latency.

ULIP: Learning a Unified Representation of Language, Images, and Point Clouds for 3D Understanding Tri-modal 预训练框架以及其下游任务。 ULIP（已经被CVPR2023接收）采用了一种独特的方法，使用3D点云、图像和文本进行模型的预训练，将它们对齐到一个统一的表示空间。

2022年12月10日 · Therefore, we introduce ULIP to learn a unified representation of images, texts, and 3D point clouds by pre-training with object triplets from the three modalities. To overcome the shortage of training triplets, ULIP leverages a pre-trained vision-language model that has already learned a common visual and textual space by training with massive ...

In this paper, we propose Learning a Unified Represen-tation of Language, Images, and Point Clouds (ULIP). An illustration of our framework is shown in Figure 1. Ob-taining a unified representation space of all 3 modalities re-quires large-scale triplets of image, text, and point cloud as training data.

ULIP与3D主干网络无关，可以轻松集成到任何3D架构中。实验表明，ULIP通过在ShapeNet55上对多个新近的3D主干进行简单的预训练，有效地提高了它们的性能，在ModelNet40和ScanObjectNN上实现了标准3D分类和零镜头3D分类的最新性能。

2023年5月14日 · We conduct experiments on two large-scale 3D datasets, Objaverse and ShapeNet, and augment them with tri-modal datasets of 3D point clouds, images, and language for training ULIP-2. Experiments show that ULIP-2 demonstrates substantial benefits in three downstream tasks: zero-shot 3D classification, standard 3D classification with fine-tuning ...

ULIP improves 3D understanding by aligning features from images, texts, and point clouds in the same space. To reduce the demand of 3D data, ULIP leverages image and text encoders that are pre-trained with large-scale image-text pairs, and aligns 3D representation to the pre-aligned image-text feature space using a small scale of training triplets.

Unit Linked Insurance Plan (ULIP) Definition: Unit linked insurance plan (ULIP) is a bundled financial product proposed for those investors who need a life cover as well. It comprises of insurance benefit along with investment opportunity, to serve the dual purpose of safety and wealth maximization to the investors.
