I plan to train a series of models to address this issue, and this is one attempt within that series. The model is based on the SDXL architecture and fine-tuned with the <a target="_blank" rel="ugc" href="https://civarchive.com/models/122606/dynavision-xl-all-in-one-stylized-3d-sfw-and-nsfw-output-no-refiner-needed">DynaVision XL model</a>.<h2 id="data-d1881zdd1">Data</h2>I have collected around 3K hand-drawn images of cars. Currently, there doesn’t seem to be a website or dataset specifically dedicated to a large collection of hand-drawn car images, so the data comes from various channels. The data has only undergone basic labeling, with no classification or human preference filtering (I didn’t have time to do this, but I may do so in the future). The data labeling has not been screened, and it is provided as-is.<h2 id="training-fwhllwv5w">Training</h2>As mentioned above, I did not choose the base model of SDXL for training. The reason is that I feel the 2D performance of the base model is not good, or rather, it is not as good as the <a target="_blank" rel="ugc" href="https://civarchive.com/models/122606/dynavision-xl-all-in-one-stylized-3d-sfw-and-nsfw-output-no-refiner-needed">DynaVision XL_ Release_v0.6.1.0-bakedvae</a> model, so I chose this model for training.The training script used is <a rel="ugc" href="https://github.com/kohya-ss/sd-scripts">sd-scripts</a>, and below are some detailed parameters.<ul><li>base_model: dynavisionXLAllInOneStylized_releaseV0610Bakedvae.safetensors</li><li>resolution: 1024</li><li>max_train_epochs = 20</li><li>device = 4090 X 2</li><li>clip_skip = 2</li><li>save_precision = fp16</li><li>network_module = lycoris.kohya</li><li>network_dim = 16</li><li>network_alpha = 8</li><li>train_batch_size = 16</li><li>gradient_checkpointing = true</li><li>gradient_accumulation_steps = 1</li><li>real_batch_size = 32</li><li>lr_scheduler = constant</li><li>min_snr_gamma = 5</li><li>multires_noise_discount = 0.3</li><li>multires_noise_iterations = 10</li><li>unet_lr = 2e-4</li><li>text_encoder_lr = 2e-4</li></ul><h3 id="other-notes-64sj3wqdv">Other Notes</h3>At now I am only releasing some test results.
