有两个方式进行下游任务的训练:(1)fine-tuning,即end-to-end训练下游任务,encoder和head都训练;(2)linear probing,即encoder固定,只训练head。 3. Method Architecture TTT的自监督训练部分使用MAE。网络架构是一个Y形(与TTT相同),用一个feature extractor f 接两个不同的head,一个是self-supervised head g ,...
关键字:开放域, without test-time fune-tuning 解决问题:开放域和非微调个性化图像生成 提出模型:Subject-Diffusion 主要贡献: 设计了一个自动数据集构建管道,并创建了一个包含7600万张开放域图像和2.22亿个实体的大规模结构化训练数据集,这对开放域主题图像生成任务非常有利。 提出了一个基于粗定位和细粒度图像控制...
However, existing personalization approaches usually require test-time finetuning for each concept, which is time-consuming and difficult to scale. We propose InstantBooth, a novel approach built upon pre-trained text-to-image models that enables instant text-guided image personalization without...
现在,我们希望引导模型在给出答案前,花更多的时间进行“思考”,也就是说,我们希望模型按照“思考步骤 + 回答”的这种格式,返回给我们response。 所以在这里我们需要先对模型做格式finetune。具体的方法是: 自生产数据:在prompt中添加格式例子,引导模型按我们想要的格式产出结果。例如,我们可以按照一个思考步骤(step)...
In deep learning, test-time adaptation has gained attention as a method for model fine-tuning without the need for labeled data. A prime exemplification is the recently proposed test-time prompt tuning for large-scale vision-language models such as CLIP. Unfortunately, these prompts have been mai...
researchers have explored methods such as RL-inspired finetuning (e.g., STaR, ReSTEM) and self-critique techniques. These approaches enable the model to enhance its own outputs at test time by critiquing and revising its initial responses iteratively. Finet...

ImageNet-V2, and ImageNet-Sketch (which has 1000 classes), you will need a GPU with more than (not including) 16GB memory. This codebase is tested on a GPU with 24GB memory. To evaluate other datasets (with less than a few hundred classes), a GPU with 16GB memory will work fine....
Ev-TTA mitigates the severe domain gaps by fine-tuning the pre-trained classifiers during the test phase using loss functions inspired by the spatio-temporal characteristics of events. Since the event data is a temporal stream of measurements, our loss function enforces similar predictions for ...
that in mind, I usually think that the sweet spot is three months. Whenever I work with one-on-one students, I always say that you should spend three months prepping, and then from there, you’re pretty much ready. Some students, it might just a little bit of a fine-tuning exercise...
