candi-sailor2-8b

Model ini eksperimental aja. Saya fine-tune pake dataset chat 1K candi pake metode LoRA.

LoRA-nya juga tersedia di HF: candi-sailor2-8b-lora.

Use case paling ok kalau mau pake model ini adalah chatbot pengenalan candi-candi di jawa tapi harus digabung sama RAG supaya hasil-nya lebih ok.

Ini target-nya lokal deployment. Cost hanya di hardware dan listrik.

Dari Dataset Statis ke Chatbot yang Nyambung

Dataset candi ini adalah fakta atau data statik: nama candi, lokasi, koordinat, alamat, ketinggian, dan deskripsi.

Tapi cara user bertanya itu dinamis.

Ada yang tanya:

“candi di Sleman apa aja?”
“yang dekat Prambanan mana?”
“koordinat Candi Lor berapa?”
“sejarah Candi Tikus?”

Lalu, gimana caranya supaya dataset statis tersebut berguna untuk chatbot?

Kalau chatbot hanya dilatih dari data statik, jawabannya bisa kaku. Maka akan lebih baik:

Pake user-generated chat data yg membantu "mengubah" dataset statis menjadi pengalaman tanya-jawab yang natural, sesuai cara manusia benar-benar mencari informasi.

AI dipakai untuk mensimulasikan cara manusia bertanya berdasarkan dataset tersebut dan hasilnya ini adalah yg disebut dengan user-generated chat data.

Lalu data-data ini nanti dipakai buat fine-tuning model + RAG.

Kayake minggu ini banyak nyusun dataset 😂

Lagi nyusun data candi-candi di pulau Jawa. Ada data lokasi, deskripsi, dan reverse geo.

Data dikit 100-an. Aslinya dulu pengen punya cuman asli memakan waktu banyak, jd males bgt. Kalau skrg ada AI gas-gas aja, yg penting fact-checking ok. hehe

@forestgeoinfo By detailed DEM, does it mean under 5m resolution?

@LambeSahamjja Ada J-drama yang menceritakan ttg proses jadi pilot cuma lupa judulnya. Ada bagian di mana calon pilot ditempatkan di field crew, baru ganti ke simulator, dan terakhir pendidikan lapangan dengan pesawat asli.

Okay team. Here it is. A 28 m resolution global map of the planet Mars, viewable on Google Earth. The starter version with just 271,790,899,200 pixels. One of the most beautiful things I have ever made. Please, enjoy!

I finally solved the biggest issue with NotebookLM Slides. 🚫✍️

We all love the aesthetic of NotebookLM's auto-generated Slide Decks, but there's a catch: they are static images. You can't edit the text, and you can't tweak the content.

Want that specific style but with full control over every word?

I built a workflow + prompt template that lets you customize everything. Here is how it works. 👇

Metaから発表された画像を3D化する #SAM3D ですが、普通に建物も3D化出来ました。ぱっと見Meshy超えてます。出力はまだ出来ないっぽいけど、数カ月分のモデリング作業が無駄になりそうな恐怖を強烈に感じます。

ぜひ皆さんも希望と絶望を体験してみてください。
