BanG Dream! Girls Band Party! (style, 30+ characters)

一个基于2396张Girls Band Party卡牌的LoRA（Hadamard Product），可识别34位角色，识别程度各不相同。

一次多角色实验，首次尝试效果超出预期。能够生成多个角色，但角色一致性仍不够理想。发丝表现尚可，但在多角色情况下常出现眼睛颜色错误。

使用方法

此Hadamard Product LoRA需安装额外扩展才能在Web UI中使用。

该风格本身无触发动机词。以下是各角色的标签及各自前20个相关标签：

训练信息

数据集：

• 从Bandori Party收集的2396张卡牌

使用 SmilingWolf/wd-v1-4-convnextv2-tagger-v2 生成标签，阈值为0.35。未进行平衡处理与标签清洗。

数据源还包含卡牌中其他角色出现的信息（客串角色）。但由于卡牌通常包含两张不同角色的图像，该信息不够准确。因此使用生成的标签来推断是否应在描述中包含客串角色名称。

描述模板为：MainChar/OtherChar1/OtherChar2..., other tags shuffled。虽然使用斜杠作为角色分隔符，但用逗号代替似乎对性能无明显影响。

训练了40个周期，但不确定是否需要这么多。10个周期的检查点已可使用。所有检查点均可在hf仓库中找到。

训练成本：约13 T4小时
