Which metal paper clip has less thermal energy? | 0 | Matter is made of tiny particles called atoms. Atoms are always moving.
The energy of moving atoms is called thermal energy. The total amount of thermal energy in matter depends on three things: the type of matter, the amount of matter, and how fast the atoms are moving.
Temperature measures how hot or cold matter is. ... | Not supported with pagination yet |
During this time, thermal energy was transferred from () to (). | 0 | A change in an object's temperature indicates a change in the object's thermal energy:
An increase in temperature shows that the object's thermal energy increased. So, thermal energy was transferred into the object from its surroundings.
A decrease in temperature shows that the object's thermal energy decreased. So, th... | |
Complete the sentence so that it uses personification.
"You might think you'll always be young," Mrs. Hensley counseled, "but time ()". | 0 | Personification is giving human characteristics to nonhuman things. It is a figure of speech that can be used to make writing more interesting or to emphasize a point.

ScienceQA Mathematics CoT Dataset (Turkish)
Bu veri seti, görsel içerikli matematik sorularının çözümü için Qwen 2.5 VL ve benzeri çok modlu (multimodal) modellerin ince ayar (fine-tuning) işlemleri için hazırlanmıştır. Orijinal ScienceQA verileri temel alınarak, görsel-metin eşleşmeleri optimize edilmiş ve çözüm yolları (Chain of Thought) yapılandırılmıştır.
📊 Veri Seti Özeti
- Toplam Satır Sayısı: 16,789
- İçerik: Görsel (Image), Soru (Question), Cevap (Answer) ve Çözüm Yolu (Solution/CoT).
- Dil: ingilizce
- Format: Hugging Face
datasetskütüphanesi ile tam uyumlu.
🚀 Hızlı Başlangıç
Veri setini projenize dahil etmek için aşağıdaki kodu kullanabilirsiniz:
from datasets import load_dataset
dataset = load_dataset("kerembb123/scienceqa-math-cot")
# Örnek bir veriyi inceleme
print(dataset['train'][0]['question'])
dataset['train'][0]['image'].show()
## 📂 Veri Yapısı
Bu veri seti, çok modlu (multimodal) modellerin hem görseli anlaması hem de adım adım mantık yürütmesi (Chain of Thought) için yapılandırılmıştır. Her bir örnek aşağıdaki sütunları içerir:
| Sütun Adı | Veri Tipi | Açıklama |
| :--- | :--- | :--- |
| `image` | `image` | Sorunun görsel içeriği (PIL.Image objesi) |
| `question` | `string` | Modelin cevaplaması gereken matematik sorusu metni |
| `answer` | `string` | Sorunun kesin ve kısa doğru cevabı |
| `solution` | `string` | Sorunun adım adım çözüm yolu (CoT - Chain of Thought) |

## 🛠️ Hazırlık Notları (Pre-processing)
Veri setinin hazırlanma sürecinde uygulanan kritik adımlar şunlardır:
1. **Görsel-Metin Eşleştirme:** Orijinal ScienceQA `train` ve `validation` parquet dosyalarındaki görseller, özel bir script ile `egitim_seti_CoT.jsonl` dosyasındaki ilgili sorularla ID bazlı olarak eşleştirilmiştir.
2. **CoT (Chain of Thought) Yapılandırma:** Sadece cevaplar değil, modelin akıl yürütme becerisini geliştirmek için `lecture` ve `solution` alanları birleştirilerek temiz bir çözüm yolu sütunu oluşturulmuştur.
3. **Veri Temizliği:** Eksik veriler (null values) ve hatalı görsel eşleşmeleri ayıklanarak 16,789 satırlık kararlı bir yapı kurulmuştur.
4. **Model Uyumluluğu:** Veri seti, **Qwen 2.5 VL** gibi güncel Vision-Language modellerinin eğitim formatına (prompt template) uygun şekilde paketlenmiştir.
5. **Eğitim Önerisi:** Yüksek çözünürlüklü görseller içerdiği için eğitim sırasında **A100 (40GB)** GPU ve **Unsloth** kütüphanesinin kullanılması hız açısından tavsiye edilir.
