从去年嵌入式模型出现以后，我就一直在学习如何训练出一个yousa的模型。或许是因为瞎猫碰上死耗子，第一个训练的嵌入式yousa模型效果还行，拟合度还不错，泛化性也能接受。
但随着大模型的不断发布和更新，旧版本的嵌入式模型也很大程度上被新的LoRA模型给取代了，由于对技术的不熟悉，新训练的LoRA模型质量一直不怎么高，不是过拟合就是欠拟合，人物训练出来了但是背景又经常固化了，泛化又不好。所以我就决定从素材开始重新准备。
本次发布的自制yousa LoRA模型共使用147张图片，其中129张是官方配布的几个MMD模型不同动作的截图，18张是yousa月刊、Pixiv不同画师的作品(部分训练图片如下图所示)。本人发布此模型仅用于爱好者的学习和讨论，严禁商用和公开的非法内容的传播以及对原创画师、其他模型作者的踩一捧一。

本模型共包含8个训练得较好的服装:
1、石英式泠鸢yousa(对应Prompt: yousa_origin,origin_hair_ornament, origin_earrings, origin_suits, origin_single_leg_ring, origin_footwear)
2、登门喜鹊(对应Prompt:yousa_magpie, magpie_hair_ornament,magpie_earrings, magpie_gloves, magpie_suits, magpie_single_leg_ring, magpie_footwear)
3、海盐柠檬(对应Prompt:yousa_SeaSaltLemon,SeaSaltLemon_minihat, SeaSaltLemon_earrings,SeaSaltLemon_suits,SeaSaltLemon_single_leg_ring,SeaSaltLemon_footwear)
4、随舰海鸥(对应Prompt:yousa_WithShipSeagull,WithShipSeagull_hat, WithShipSeagull_hair_ornament, WithShipSeagull_suits, WithShipSeagull_footwear)
5、披风朋克(但没有披风)(对应Prompt:yousa_punk, punk_hair_ornament, punk_earrings, punk_suits, punk_stockings, punk_footwear)
6、舞台之星(对应Prompt:yousa_StageStar, StageStar_hat, StageStar_earrings, StageStar_suits, StageStar_single_leg_ring, StageStar_footwear)
7、小红鸢石英式(洛丽塔)(对应Prompt: yousa_LittleKite, LittleKite_hair_ornament, LittleKite_earrings, LittleKite_suits, LittleKite_socks, LittleKite_footwear)
8、演唱会(对应Prompt: yousa_concert, concert_hair_ornament, concert_earrings,concert_single_gloves, concert_suits, concert_footwear)
以上服饰皆可通过yousa_服饰名(例如yousa_origin、yousa_SeaSaltLemon)来进行调用，其他服饰部件可搭配使用，但需要注意可能会影响背景及其他细节。
经过前两天的测试，animefull模型作为底模同参数下训练出的LoRA远不如其他模型，而其他2.5D模型训练的LoRA泛化度则不如anything-v4.5。因此本模型基于anything-v4.5进行训练，对anything-v4.5、aom3、cetusMix_Coda(2)、CounterfeitV25、aoaokoPVCStyleModel支持较好，对pastelmix、aniflatmixAnimeFlatColorStyl、anythingV5_PrtRE支持并不好，不建议使用。
融合模型非常多建议各位自己测试一下其他模型的泛化度。
训练原始分辨率(768x768)+基础Prompt(Prompt:masterpiece, best quality, 1girl, solo, yousa, <lora:yousa_v1.0.0:1>，Negative Prompt:easynegative, bad_prompt_version2, simple background, white background)生成测试结果如下图所示。

此LoRA建议权重设置为0.6~1.1，采样方法和迭代步数请根据实际情况自行调整，推荐使用Hires. fix或Tiled Diffusion +Tiled VAE或Ultimate SD upscale进行图片放大。推荐使用ControlNet控制人物肢体。
以下例图皆未使用ControlNet，仅使用easynegative和bad_prompt_version2嵌入式模型和Hires. fix +Tiled Diffusion +Tiled VAE进行放大。
