English ↔ Roman Urdu
The trained weights for an 81M-parameter encoder–decoder transformer written
from primitives in PyTorch — no nn.Transformer, no AutoModel, no training
framework.
Roman Urdu is Urdu written in English letters, which is how Urdu is actually typed in messages. One model translates both directions and detects which one is wanted from the input.
| Parameters | 81M (d_model 512, 6+6 layers, 8 heads, d_ff 2048) |
