Improving the model for pruning the TX type search
Introduces two new TX type pruning modes that provide better
speed-quality trade-off compared to the existing ones. A shallow
neural network with one hidden layer trained separately for each
block size is used as a prediction model. The new modes differ in
thresholds applied to the output of the neural net, so that they
prune different number of TX types on average.
Owing to relatively low quality loss PRUNE_2D_ACCURATE is used
by default, regardless of speed settings. Starting with speed
setting of 3 we switch to PRUNE_2D_FAST mode to get better
speed-up.
Evaluation results:
----------------------------------------------------------
Prune mode | Avg. speed-up | Quality loss | Quality loss
|(high bitrates)| (lowres) | (midres)
----------------------------------------------------------
PRUNE_ONE | 18.7% | 0.396% | 0.308%
----------------------------------------------------------
PRUNE_TWO | 27.2% | 0.439% | 0.389%
----------------------------------------------------------
PRUNE_2D_ | 18.8% | 0.032% | 0.063%
ACCURATE | | |
----------------------------------------------------------
PRUNE_2D_ | 33.3% | 0.504% | ---
