V4.0:

Trained with NoobAi early access version checkpoint with 90 epochs and batch size=4(stopped at 68st epoch), using AdamW scheduler with 5e-5 learning rate, DIM=64, alpha=64

Updated new clothings(the sky trail and echo' clothings), improve a bit of quality of the model(the clothing problems stated in V2.0 are still persisted, but have improved a bit). Remember to not use cat hood since it has already blended into the hood tag

There is hairstyle problem of this model, since introducing french braid tag on the sky trail hairstyle of Kohaku. I will try to tackle this in the next version.

Btw I am considering adding Kohaku clothings(since there are many similarities in game design of these two characters) into this model, which may add more variety of clothings.

V3.0:

Trained with NoobAi early access version checkpoint with 60 epochs and batch size=1(stopped at 41st epoch), using AdamW scheduler with 1e-4 learning rate, DIM=64, alpha=64

Expanded the training dataset, most of the problems are the same as V2.0, but the quality of the model should be highly enhanced(I hope so)

Please reference to V2.0 taggings when using it. Also avoid using cat hood tag.

Version 2.0 description:

I have revamped the model, including re-tagging and re-selection of data. Still trained with noobai early access version checkpoint with 70 epochs(stopped at 50th epoch), with trained batch size=8, net dim=64

Since the taggings are revamped, the triggering words of v1.0 and 2.0 are totally different, please be reminded.

I tried my best to reproduce the clothing, really. Will keep pushing v3.0 once any breakthrough is found

___New update Notes:___

It seems that there is some learning mistake on "cat hood" and "clothes writing" tags, considering remove them before usage. The black jacket/black coat has learnt the cat hood feature.

Compulsory tagging:

noa\(maimai\), 1girl,

face styles with hair:

black hair, green eyes

brown hair, blonde hair, multicolored hair, blonde eyes,

blonde hair, blonde eyes,

Clothings:

-Noa clothings with Refvain(リフヴェイン ) style:

noa\(maimai\), 1girl, ahoge, brown hair, blonde hair, multicolored hair, yellow eyes, green nails, black coat, clothes writing, green ribbon, white shirt, cat hood, hood down, green armband, sleeves past wrists, black choker, oversized clothes, wide sleeves,

-Noa clothings with Riffrain, Kairos and Amber Chronicle(アンバークロニクル) style:

noa\(maimai\), 1girl, ahoge, brown hair, blonde hair, multicolored hair, yellow eyes, green nails, black jacket, short jacket, breast pocket, green ribbon, grey shirt, black pants, black boots, cat hood, hood up, green armband, sleeves past wrists, standing, belt collar,

-Noa clothings with CERCA/ESOTERICA(チエルカ/エソテリカ) style: (half-baked, still acceptable IMO)

noa\(maimai\), 1girl, ahoge, brown hair, blonde hair, multicolored hair, yellow eyes, green nails, black jacket with green interior, clothes writing, grey shirt, black pants, black sneakers, cat hood, hood down, green armband, sleeves past wrists, high collar, black ribbon, back bow,

-Noa clothings with Six Plan(シックスプラン) style: (half-baked, still acceptable IMO) (blue and green)

I have to say, the tag recognition is not good for this, so it's hard to control the color of jacket to be blue or green by using the Blue version tags.

Blue version:

noa\(maimai\), 1girl, ahoge, brown hair, blonde hair, multicolored hair, yellow eyes, yellow nails, black jacket with blue interior, belt jacket, short jacket, stripped jacket, belt choker, piercing, buckle, black pants, cat hood, hood down, sleeves past wrists,

Version 1.0 are as below:

Introduction(of my puny little creation):

I am tired.

After I have struggled with it over 25 times of training, I have had enough of this.

Noa is my most favourite character in Maimai, but the number of fan art is not as much as popular characters like salt and acid, and so I decide to create it by myself instead. Yet my artistic sense is just too weak, so I try to leverage the power of AI.

This model is the reason why I want to learn AI picture generation and AI model training.

I want Noa model to be good and stable enough to create pictures, but seems I have failed, with many times of trials and dataset adjustments.

I even forget how I kind of successfully produced this version of model, since I cannot reproduce the result with the same configuration and dataset. And to be honest I can't even tell if it is undertrained or overtrained. But anyway.

Enough with my bullshit, lets get straight into the point.

Model training:

Trained with noobai early access version checkpoint with 90 epochs(stopped at 27th epoch), with trained batch size=1, the dataset to be used contain 75 pictures, including sketches, detailed drawings, chibi pictures etc. The dominant pictures are mainly similar styles, but consist of different patterns on similar clothing (this causes a real trouble on generating clothes with the same pattern consistently, which I can't solve at the time of release)

Problems:

1. Inconsistent clothes pattern with same tags,

2. Different color of clothes may be generated even specifying certain color clothing

3. Cat ears are very likely to generate when mentioning animal hood and cat hood

These two are the main problems I observed. The artist tags prompt may not work as you intended, since mine have this problem. But I have to say I lack of a stable artist tags prompt to produce same art style through all LoRAs I have, I decided to put this testing away and just leave it on.

Taggings:

The below taggings prompt are just for reference, I will list out the special tags that I am aware to train on:
Noa(maimai), black jacket in cyberpunk style with green color interior, black jacket with green color interior, black jacket with green color square pattern interior, black jacket with blue color square pattern interior, black choker, black belt choker, cat hood, clothes writing, belt collar jacket,

-Noa clothings with Refvain(リフヴェイン ) style:

Noa(maimai), 1girl, ahoge, fang, white shirt, shirt, collarbone, hooded jacket, jacket, black jacket, animal hood, cat hood, medium hair, green eyes, black hair, hood down, black choker, hair between eyes, armband, long sleeves, black jacket in cyberpunk style with green color interior, clothes writing, collarbone, oversized jacket, hood down, oversized clothes,

The problem is that I don't really like Noa in black hair, and the art style of Refvain is just too hard to reproduce, so I don't think this prompt looks good lol. But I love Refvain Noa sooooo much.

I strongly prefer using brown hair in this prompt instead of black(just personal preference)

(black jacket in cyberpunk style with green color interior) This tag is really hard to train as it is not an official tag, and the jacket is actually poorly trained IMO. But I just let it be.

-Noa clothings with Riffrain, Kairos and Amber Chronicle(アンバークロニクル) style:

Noa(maimai), 1girl, ahoge, fang, grey shirt, shirt, collarbone, hooded jacket, jacket, black jacket, animal hood, cat hood, green eyes, short hair, brown hair, blonde hair, multicolored hair, hood up, black belt collar, hair between eyes, armband, long sleeves, black pants, black boots, black jacket with green color interior, pocket, short jacket, collarbone, hood down, black ribbon, green ribbon,

Honestly I think this prompt clothings is trained really well, and I am satisfied with this. Again the performance strongly influenced by artist tags prompt, so beware.

-Noa clothings with CERCA/ESOTERICA(チエルカ/エソテリカ) style:

Noa(maimai), 1girl, short hair, blonde hair, yellow butterfly, bug, black pants, pants, hood, blonde hair, yellow eyes, black jacket in cyberpunk style with green color interior, black jacket, clothes writing, hooded jacket, grey shirt, long sleeves, one eye covered, hood up, black sneaker, black footwear, animal hood, cat hood, mask, grin, hair over one eye, armband,

I have to say, I seldomly use these tags, and I just randomly generate this prompt before the release. Forgive me.

-Noa clothings with Six Plan(シックスプラン) style: (FAILED)

Noa(maimai), 1girl, ahoge, fang, white shirt, shirt, collarbone, black jacket with green color square pattern interior, hooded jacket, belt pouch, jacket, black jacket, animal hood, cat hood, green eyes, brown hair, hood up, black belt collar, belt collar jacket, hair between eyes, armband, long sleeves, black pants, black sneakers, pocket, short jacket, collarbone, looking at viewer, solo, hood down, black ribbon, green ribbon,

Welp. This is so messed up.

(black jacket with green color square pattern interior) (black jacket with blue color square pattern interior) Since the steps and epochs are limited with few pictures on Six Plan Noa, I failed to reproduce this style, and the corresponding clothings tags are bad. This tag prompt is just for reference, and maybe you are lucky enough to generate one usable picture.

Optional tags: (just for reference and styles used in dataset)

unworn jacket, jacket on shoulder, sleeves past wrists, oversized clothes, open jacket, open clothes, bandaid on face, white shirt with green collar, hair over one eye, spot color, colored inner hair
