Contact Binary Light-curve Analyzer (CBLA)
Kai Li
This is a neural network model trained on theoretical light curves generated by PHOEBE, designed for analyzing contact binary light curves. The software enables: 
Multi-band light curve processing - Simultaneous analysis of observations across different passbands
Comprehensive parameter determination - Accurate estimation of:
• Temperature ratio (T₂/T₁)
• Mass ratio (q)
• Orbital inclination (i)
• System potential (Ω)
• Contact degree (f)
• Component luminosities (L₁, L₂)
• Relative radii (r₁, r₂)
• Third light contribution (l₃)
• Spot parameters 
The software has been compiled into a standalone Windows executable (.exe) and  a Linux executable for convenient deployment.
