AI Model Training Time Calculator
Estimate the time to train a machine learning model based on dataset size, model complexity, and hardware performance.
Formulas Used
The training time is estimated by calculating the total computational work (FLOPs) and dividing by hardware performance.
- Total FLOPs:
\\[ F_{\text{total}} = N \cdot C \cdot F_{\text{base}} \\]
Where:
- \\( F_{\text{total}} \\): Total floating-point operations (FLOPs)
- \\( N \\): Dataset size (samples)
- \\( C \\): Complexity multiplier (1, 10, 100, 1000)
- \\( F_{\text{base}} \\): Base FLOPs per sample (1e12 FLOPs/sample)
- Training Time (seconds):
\\[ T_{\text{sec}} = \frac{F_{\text{total}}}{P \cdot 1e12} \\]
Where:
- \\( T_{\text{sec}} \\): Training time (seconds)
- \\( P \\): Hardware performance (TFLOPS)
- \\( 1e12 \\): Converts TFLOPS to FLOPs/second
- Training Time (hours):
\\[ T = \frac{T_{\text{sec}}}{3600} \\]
Where:
- \\( T \\): Training time (hours)
- \\( 3600 \\): Seconds per hour
- Time Category:
Based on \\( T \\):
- Fast: \\( T \leq 1 \, \text{hour} \\)
- Moderate: \\( 1 < T \leq 24 \, \text{hours} \\)
- Slow: \\( 24 < T \leq 168 \, \text{hours} \\)
- Very Slow: \\( T > 168 \, \text{hours} \\)
Example Calculations
Example 1: Simple Model on Small Dataset
Inputs: Dataset Size = 10,000 samples, Model Complexity = Simple (1), Hardware Performance = 10 TFLOPS
Calculations:
- Total FLOPs: \\[ 10000 \cdot 1 \cdot 1e12 = 1e16 \, \text{FLOPs} \\]
- Training Time (seconds): \\[ \frac{1e16}{10 \cdot 1e12} = 1000 \, \text{seconds} \\]
- Training Time (hours): \\[ \frac{1000}{3600} \approx 0.28 \, \text{hours} \\]
- Time Category: Fast (≤1 hour)
Result: Training Time: 0.3 hours (Fast)
Example 2: Complex Model on Medium Dataset
Inputs: Dataset Size = 1,000,000 samples, Model Complexity = Complex (100), Hardware Performance = 50 TFLOPS
Calculations:
- Total FLOPs: \\[ 1000000 \cdot 100 \cdot 1e12 = 1e20 \, \text{FLOPs} \\]
- Training Time (seconds): \\[ \frac{1e20}{50 \cdot 1e12} = 2000000 \, \text{seconds} \\]
- Training Time (hours): \\[ \frac{2000000}{3600} \approx 555.56 \, \text{hours} \\]
- Time Category: Very Slow (>168 hours)
Result: Training Time: 555.6 hours (Very Slow)
Example 3: Moderate Model on Large Dataset
Inputs: Dataset Size = 500,000 samples, Model Complexity = Moderate (10), Hardware Performance = 100 TFLOPS
Calculations:
- Total FLOPs: \\[ 500000 \cdot 10 \cdot 1e12 = 5e18 \, \text{FLOPs} \\]
- Training Time (seconds): \\[ \frac{5e18}{100 \cdot 1e12} = 50000 \, \text{seconds} \\]
- Training Time (hours): \\[ \frac{50000}{3600} \approx 13.89 \, \text{hours} \\]
- Time Category: Moderate (1–24 hours)
Result: Training Time: 13.9 hours (Moderate)
