He was the most famous Pallas's cat in China.</p><p>Thanks to the consistent popular science efforts of Xining Wildlife Zoo and the immense charm of Sun Simiao and his family, the Pallas's cat has gradually gained fame from being unknown, along with the snow leopard and chinese mountain cat, greatly raising public awareness of animal conservation and ecological construction on the Qinghai-Tibet Plateau.</p><p>Sun Simiao got his name from his first observed mating behavior, which lasted only 4 seconds, thus the name came from a homophonic pun. His life started with a jesting name and ended in a jesting manner. On October 10th last year, <a target="_blank" rel="ugc" href="https://www.scmp.com/news/people-culture/trending-china/article/3195568/fat-sacred-beast-cute-pallass-cat-chokes-death">he died</a> of suffocation from choking on a chicken bone because he was eating too fast. Typically, the lifespan of a captive Pallas's cat is around 12-15 years. Sun Simiao was in his prime at 7 years old. My friends who love Pallas's cats were all greatly shocked and saddened.</p><p>In February this year, I first became acquainted with the LoRA model, and the first model I made was the Pallas's cat LoRA. As a lesser-known species, neither the midjourney nor the official stable diffusion models can accurately output the image of a Pallas's cat. LoRA is a perfect means of fine-tuning this niche concept. My initial Pallas's cat LoRA was a general model similar to <a target="_blank" rel="ugc" href="https://civitai.com/models/33208/leosams-filmgirl-film-grain-lora-and-loha">filmgirl</a>, trained on 300 photos of different Pallas's cat individuals. After completing this model, my second LoRA model was a dedicated LoRA for Sun Simiao. For this, I collected a total of 263 photos of Sun Simiao from my Pallas's cat friends, 70% of which were from @yspenny, and 30% were from @西宁野生动物园, @圆掌, and @天音文创馆. However, the results were not good, mainly for three reasons:</p><ol><li><p>The vast majority of photos were taken by mobile phones, cropped from distant views, and generally blurred with automatic filter colors.</p></li><li><p>The glass of the kitten hall at Xining Wildlife Zoo has a green tint and severe reflections, further degrading the image quality.</p></li><li><p>Sun Simiao lived all his life in the small exhibition room of the kitten hall, resulting in a single, fixed scene.</p></li></ol><p>These issues led to a low output rate for the model and required a lot of rolling to generate images. Therefore, I didn't publish this version of the Sun Simiao LoRA model publicly but often ran the notebook overnight to generate images and then selected what I thought were the best images the next morning to post on my animal science popularization account. I once joked on Weibo that this extensive image screening was AI reverse fine-tuning my brain, distorting my memory of what Sun Simiao really looked like, so I had to look at real photos to cleanse my eyes after a while.</p><p>Now, however, there are new solutions to these problems. While there are still many shortcomings, the SDXL model is undeniably stronger in performance, and the ceiling is higher. Just before the first anniversary of Sun Simiao's death, I decided to make another dedicated image upgraded base model LoRA model for Sun Simiao. In response to the shortcomings of the model, I tried the following improvements:</p><ol><li><p>Considering that the SDXL model is extremely sensitive to the quality of the training set and the original training set is of uneven quality and generally blurry, I re-selected the training set to 224 images. In the process of eliminating a batch of images, I also used AI to enhance the quality of some salvageable training images.</p></li><li><p>I added 1006 carefully selected photos of Pallas's cat individuals from around the world to the regularization set. For training, I used a combination of natural language and label tagging, and tested the triggering effects of different trigger words to seek an appropriate distinction and connection between the Sun Simiao training set and the Pallas's cat regularization set. I tried to avoid polluting the individual's appearance while enhancing hair detail with the regularization set and generalizing the background environment and expression posture.</p></li><li><p>I used adam8bit, DAdaptAdam, Prodigy, and adaFactor four optimizers for training. I compared and merged the output models and finally selected the most satisfactory one. This way, the model could incorporate the strengths of each optimizer, creating a more robust and accurate representation of Sun Simiao.</p></li></ol><p>In the end, the model produced was far better than the previous one. The images generated were more realistic and captured the essence of Sun Simiao much better. The model was also more consistent in generating images that were specific to Sun Simiao, with his unique markings and characteristics.</p><p>This project has been an emotional journey, as it allowed me to remember Sun Simiao in a unique way. I believe this model is a fitting tribute to his life, and I hope it will inspire others to learn more about Pallas's cats and the importance of wildlife conservation.</p>
