## Manual decoding of server output
If you want to decode `output.txt` yourself:
```bash ```bash
python3 - << 'EOF' python3 client.py \
import numpy as np --input_file input.txt \
import encoder, decoder --output_file output.txt \
--hostname iscsrv72.epfl.ch \
# Load noisy samples --port 80
Y = np.loadtxt("output.txt")
# Rebuild codebook
C = encoder.make_codebook(r=5, num_blocks=40)
# Decode
msg = decoder.decode_blocks(Y, C)
print("Decoded message:", msg)
EOF
``` ```
---
Feel free to adjust `--trials` or swap between `local` and `server` modes as needed.
