However, fine-tuning it for small downstream tasks with limited labeled samples is challenging. Efficient transfer learning (ETL) methods adapt VLMs with few parameters, but require careful per-task hyperparameter tuning using large validation sets. To overcome this, the authors propose CLAP, a principled approach that adapts linear probing for few-shot learning. CLAP consistently outperforms ETL methods, providing an efficient and robust approach for few-shot adaptation of large vision-language models in realistic settings where hyperparameter tuning with large validation sets is not feasible. |

    • Doodle Your 3D: From Abstract Freehand Sketches to Precise 3D Shapes - 2312.04043-b31b1b.svg?style=for-the-badge)](https://ar5iv.labs.arxiv.org/html/2312.04043) | This paper introduces a new method for generating precise 3D shapes from abstract freehand sketches, without the need for paired sketch-3D data. The approach uses a part-level modeling and alignment framework, which enables sketch modeling and in-position editing. By operating in a low-dimensional implicit latent space and using diffusion models, the approach significantly reduces computational demands and processing time. Overall, the method offers a novel solution for enabling accurate 3D generation from abstract sketches. |

This approach allows for precise animation control while maintaining photorealistic rendering. The technique has shown impressive animation capabilities in challenging scenarios, such as reenactments from a driving video, where it outperforms existing techniques by a significant margin. |
    • Open-Vocabulary 3D Scene Graphs from Point Clouds with Queryable Objects and Open-Set Relationships - vocabulary 3D scene graphs from point clouds, combining vision-language and large language models. Key ideas include constructing a 3D graph with a GNN, aligning features with CLIP, and using an LLM. It allows querying arbitrary objects and relationships at inference time, and enables open-vocabulary prediction not limited to fixed labels. |

It computes 3D semantic features using pre-trained 2D diffusion models, rendering depth and normal maps from multiple views, and lifting the 2D diffusion features back to the 3D surface. This produces semantic descriptors on the 3D shape without requiring additional training data or part segmentation. |

DMD matches the distribution of the original diffusion model by minimizing KL divergence and using two score functions - one for the actual data distribution and one for the generated distribution. A regression loss matches the large-scale structure of the multi-step diffusion outputs. |

Previous methods used manual annotation, but the authors use 3D data to construct the MP3D-Amodal dataset with authentic amodal ground truth masks. Two architecture variants are explored: a two-stage OccAmodal model and a one-stage SDAmodal model. Their method achieves state-of-the-art performance on amodal segmentation datasets, including COCOA and the new MP3D-Amodal dataset. |
