ocr-gan's Introduction

Jiangning Zhang (张江宁) works as a Principal Researcher of two teams (Industry Perception and AIGC) at YouTu Lab, Tencent, Shanghai. I receive Ph.D. degree in College of Control Science and Engineering, Zhejiang University, Hangzhou, China, under the supervision of Prof. Yong Liu. My major is Computer Vision and my research interests include:
🌱 GAN-/Diffusion-based AIGC researches with LLM, e.g., multi-modal image/video generation, 2D/3D virtual digital human related researches (3D face/body/hand reconstruction, multi-modal digital human drive, motion generation, etc.), text-to-image generation, multi-modal human-centric editing and generation, etc.
🌱 Neural Architecture Design (NAD), e.g., transformer-based architecture, light-wight vision model, etc.
🌱 Anomaly Classification and Segmentation.

  • 💬 Feel free to drop me emails ([email protected]) if you have interests on above topics, and remote cooperations are welcomed.
  • 💬 You can contact me if you are applying for a Research Intern or a B.S./Ph.D. student in computer vision / robotic perception, and I co-supervise students with Prof. Yong Liu at Zhejiang University.
  • 💖 I love 📷photography, 🍲cooking, and 🌏traveling, enjoy together!!!!!!

ocr-gan's Issues

关于AUC不一致性的两个问题

  1. 训练过程中,每次epoch都会做一遍test,然后保存最高auc对应的模型参数。但是训练结束后,加载保存的模型参数,重新做test,并不能得到跟train的过程中做的test相同的auc。

  2. test时,使用不同的batch_size会得到差别很大的结果

gt设置疑问

ocr_gan_aug.py的test中,self.gt_labels设置为异常为0,正常为1。但是异常分数是越高越异常,这样算出来的auc是错误的吧?

basemodel_aug.py里的问题

在get_current_images():方法中,返回值为四个,但在def train_one_epoch(): 接收值为三个
def get_current_images(self): """ Returns current images. Returns: [reals, fakes, fixed] """ reals = self.input_lap.data + self.input_res.data fakes = self.fake.data fake_lap = self.fake_lap.data fake_res = self.fake_res.data return **reals, fakes, fake_lap, fake_res**
def train_one_epoch(self): """ Train the model for one epoch. """ self.netg.train() epoch_iter = 0 for data in tqdm(self.data.train, leave=False, total=len(self.data.train)): self.total_steps += self.opt.batchsize epoch_iter += self.opt.batchsize self.set_input(data) self.optimize_params() if self.total_steps % self.opt.print_freq == 0: errors = self.get_errors() if self.opt.display: counter_ratio = float(epoch_iter) / len(self.data.train.dataset) self.visualizer.plot_current_errors(self.epoch, counter_ratio, errors) if self.total_steps % self.opt.save_image_freq == 0: **reals, fakes, fixed** = self.get_current_images()

關於論文期刊

您好,根據paperwithcode,
您的論文是目前MVtec benchmark上面,
不使用額外訓練資料以及預訓練網路的條件下,
結果最佳的方法,
想請問為什麼只放在arxiv上而不投稿其他conference或journal呢
