因此,在这篇文章中,提出一个对于目标检测的新的问题定义--open vocabulary object detection. 这是一个相比于弱监督和零样本学习 更一般性的,更实际的,更有效的形式。 open-vocabulary / zero-shot / weakly supervised 之间的差异 How is Open-Vocab? 对于在训练期间没有明确 bbox annotation的物体, 本文提出的...
These multi-level point-caption pairs offer coarse-to-fine supervision signals, facilitating learning adequate visual-semantic representations from rich vocabu- lary by contrastive learning. Without task-specific design, our Point-Language Association paradigm, namely PLA, is generic ...
左边:出去了CPE部分就是大家熟悉的用{img, caption} 作为pairs进行contrastive learning学习; 但是loss从原本的softmax改成了focal loss; 中间:CPE部分,也就是这篇论文如何在pretrain阶段实现region-awareness,也就是对原本的fully image position embedding改成1)先upsample成OD的常见尺寸,比如原来的embedding是224x224...
As described in Section 3.3 of the main paper, RAL defines hard and easy negative vocabu- laries through rank variance sampling of negative retriev- ers from the vocabulary store. To ascertain the optimality of the rank variance sampling method, we compared vari- ous sampling schemes...

Since we do not implement error detection or correction, our state machine model is a simple linear chain of steps leading from navigating to object, to grasping, to navigating to goal, and to dropping the object at the goal to finish the task. 状态机模型:不同模块之间的转换自动发生,按照...

Teaching robots to respond to open-vocab queries with CLIP and NeRF-like neural fields - notmahi/clip-fields
Open-Vocab 3D Instance Segmentation methods (OV-3DIS) have recently demonstrated their ability to generalize to unseen objects. However, these methods still depend on predefined class names during testing, restricting the autonomy of agents. To mitigate this constraint, we propose a novel problem ter...
