Lambda values missing for neural codecs #278

Closed awgansekoele closed 5 months ago

awgansekoele commented 5 months ago

The package has quality levels for each model but does not report the lambda values that correspond to these quality levels. Would it be possible to add those?

YodaEmbedding commented 5 months ago

The lambda values are listed here:

https://interdigitalinc.github.io/CompressAI/zoo.html#training

They are logarithmically interpolated between 0.0018 and 0.1800:

$$\lambda_Q = 0.0018 \cdot 10^{\frac{2(Q-1)}{7}}$$
