最近MetaAI发布的segment anything在cv界可谓是独枝一秀,虽然其在大部分数据效果不错,但在个别数据上分割效果不是特别理想,最近在做sam模型微调,看到类似的blog,learn-how-to-fine-tune-the-segment-anything-model-sam,内容记录一下,思路也比较简单。 1.数据集介绍 stamp verification数据集,用sam预训练模型效果如...
low_res_masks, iou_predictions = sam_model.mask_decoder( image_embeddings=image_embedding, image_pe=sam_model.prompt_encoder.get_dense_pe(), sparse_prompt_embeddings=sparse_embeddings, dense_prompt_embeddings=dense_embeddings, multimask_output=False, ) 这里的最后一步是将遮罩升级回原始图像大小,因...
这篇是针对diffusion model的finetune, 文本指导生成图像. 一起拿来读是感觉一些tuning技巧也可拿到SAM上用. 摘要指出, 大模型落地到下游任务, 逃不开把小数据集的特定知识给到网络(局部Encoder, decoder也好, 丰富的prompt也好).Controlnet通过控制大模型学习特定下游任务的"依赖",实现特定知识传递. 小数据集也可tune...
Finetune-Anything further encapsulates the three parts of the original SAM, i.e., Image Encoder Adapter, Prompt Encoder Adapter, and Mask Decoder Adatper. We will support the base extend-SAM model for each task. Users also could design your own customized modules in each adapter, use FA to...
You need to supply the datasets for your tasks and the supported task name, this tool will help you to get a finetuned model for your task. You are also allowed to design your own extend-SAM model, and FA supply the training, testing and deploy process for you. Design Finetune-Anythin...
However, to tailor a general-purpose foundation model for the unique needs of your business, you must create a fine-tuned version of it. One cost-effective fine-tuning technique is Low-Rank Adaptation (LoRA). The principle behind LoRA is that only a small part of a large foundation model ...
After a large language model is fine-tuned with supervised learning, it will be able to generate task-specific completions of its own. The next step in the RLHF process is to collect human feedback on these completions, specifically in the form of comparisons. This comparison data is the...
