## Key Insight

<p align="center">
  <img src="assets/geko_insight.png" alt="GEKO Insight" width="700">
</p>

Traditional training treats all samples equally:

$$\mathcal{L}_{standard} = \frac{1}{N} \sum_{i=1}^{N} \ell(x_i, y_i)$$

**GEKO** weights samples by their learning value:

$$\mathcal{L}_{GEKO} = \frac{1}{N} \sum_{i=1}^{N} w_i \cdot \ell(x_i, y_i) \quad \text{where} \quad w_i = f(bucket_i)$$

---

## Installation

```bash
pip install geko
```

---

## Quick Start

```python
from geko import GEKOTrainer, GEKOConfig
from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("gpt2")
tokenizer = AutoTokenizer.from_pretrained("gpt2")

trainer = GEKOTrainer(
    model=model,
    tokenizer=tokenizer,
    train_dataset=your_dataset,
)

trainer.train()
print(trainer.get_efficiency_report())
```

### Sample Partitioning

```mermaid

    A[Sample] --> B{Correct?}
    B -->|Yes| C{Confident & High Quality?}
    B -->|No| D{High Confidence?}
    C -->|Yes| E[🔵 FREEZE<br/>w = 0<br/>Never train]

```

### Bucket Definitions

| Bucket | Condition | Weight | Description |
|:------:|:----------|:------:|:------------|
| 🔵 **FREEZE** | $correct \land c > 0.85 \land q > 0.80$ | $w = 0$ | Mastered |
| 🟢 **LIGHT** | $correct \land (c \leq 0.85 \lor q \leq 0.80)$ | $w = 0$ | Uncertain |
| 🟠 **FOCUS** | $\neg correct \land c \leq 0.60$ | $w = 1$ | Wrong |
| 🔴 **HARD** | $\neg correct \land c > 0.60$ | $w = 3$ | **Confident-wrong** |

## Mountain Curriculum

<p align="center">

```mermaid
%%{init: {'theme': 'base', 'themeVariables': { 'primaryColor': '#3498db'}}}%%
xychart-beta
    title "Mountain Curriculum - Difficulty vs Progress"
    x-axis "Training Progress" [0, 0.15, 0.35, 0.65, 0.85, 1.0]
    y-axis "Difficulty" 0 --> 1
    line [0.2, 0.5, 1.0, 1.0, 0.5, 0.2]
```

### Five Phases

```mermaid

    dateFormat X
    axisFormat %s

    section Difficulty
    WARMUP (Easy)       :a1, 0, 15
    ASCENT (Medium)     :a2, 15, 35
    PEAK (Hard)         :a3, 35, 65
    DESCENT (Medium)    :a4, 65, 85
    CONSOLIDATE (Easy)  :a5, 85, 100
```

| ASCENT | 15-35% | 2 | 3 | 1 | Increase difficulty |
| PEAK | 35-65% | 5 | 2 | 0 | Maximum learning |
| DESCENT | 65-85% | 2 | 3 | 1 | Reduce difficulty |
| CONSOLIDATE | 85-100% | 1 | 2 | 3 | Reinforce |

## Q-Value Learning

<p align="center">
  <img src="assets/q_value_learning.png" alt="Q-Value Learning" width="600">
</p>

Each sample maintains a Q-value representing "learnability":

$$Q_{t+1}(s) = (1 - \alpha) \cdot Q_t(s) + \alpha \cdot \left(1 - \frac{\ell_t(s)}{\ell_{max}}\right)$$

```mermaid
graph LR
    A[Sample Loss ↓] --> B[Q-Value ↑]
    B --> C{Q > threshold?}
    C -->|Yes| D[Move to FREEZE]
    C -->|No| E[Stay trainable]

    style D fill:#3498db,color:#fff
    style E fill:#f39c12,color:#fff

## Efficiency Analysis

### Compute Savings Over Time

```mermaid
%%{init: {'theme': 'base'}}%%
pie showData
    title "Bucket Distribution (Epoch 10)"
    "FREEZE (Saved)" : 80
    "LIGHT" : 15
    "FOCUS" : 4
    "HARD" : 1
```

### Training Progression

| Epoch | FREEZE | LIGHT | FOCUS | HARD | **Compute Saved** |
|:-----:|:------:|:-----:|:-----:|:----:|:-----------------:|
| 1 | 0% | 20% | 60% | 20% | 0% |

| 3 | 35% | 30% | 25% | 10% | **35%** |
| 5 | 55% | 25% | 15% | 5% | **55%** |

## Theoretical Guarantees

### Convergence

Under standard assumptions, GEKO converges:

$$\sum_{t=1}^{\infty} w_t^{(s)} = \infty \quad \forall s \notin \text{FREEZE}$$

### Efficiency Bound

$$T_{GEKO} \leq T_{standard} \cdot (1 - \mathbb{E}[F])$$

Where $\mathbb{E}[F]$ = expected freeze fraction.
