Loss Functions Explained | Why ML Models Learn Through Loss (Beginner Friendly)

Loss function Machine Learning ka sabse important concept hai — aur is video mein hum isko bilkul simple visuals ke saath samjhenge.

Agar aap Loss ko samajh gaye,
to training loop, backpropagation, neural networks — sab crystal clear ho jayega.

What You Will Learn

✔ Loss kya hota hai
✔ Model galti kaise measure karta hai
✔ Loss high/low ka simple meaning
✔ Loss ka pattern learning mein role
✔ Why “less loss = smarter model”
✔ Common loss functions explained simply:
— MSE (Mean Squared Error)
— MAE
— Cross-Entropy (sirf intuition)
✔ Visual examples & mini demos

Perfect for beginners learning AI, ML, or Deep Learning.

Simple Explanation Used in the Video

Loss = model ki galti ka number.
High loss → model zyada galat
Low loss → model sahi direction mein

Model training ka single goal:
Loss ko kam karna.
