  2. swbd : (#1205)

    vijayaditya committed Nov 23, 2016
    1. Added TDNN+LSTM recipe which performs similar to BLSTM
    model with significantly smaller latency (21 frames vs 51 frames).
    2. Added BLSTM results in xconfig setup, without layer-wise
    discriminative pre-training (2.7% rel. improvement)
    3. Added an example TDNN recipe which uses subset of feature vector from
    neighboring time steps (results pending).
    
    xconfig : Added a tdnn layer which can deal with subset-dim option.

  2. Xconfigs : extension (#1197)

    vijayaditya committed Nov 21, 2016
    * xconfig : A very concise representation of nnet3 architectures which enables the specification of complex neural networks without the verbosity. To achieve this compactness this config
     1. uses the abstraction of layers
     2. compact descriptor representation 
          e.g. `Append(Offset(prev_layer, -3), prev_layer, Offset(prev_layer, 3))` --> `Append(-3, 0, 3)`. (For more details see #1124.)
    
    Basic layer types and LSTM layer are currently supported. Example recipes have been added in egs/swbd/s5c/local/chain/*.sh . 
    
    Another major change is the elimination of layer-wise discriminative pretraining in the new recipes; as it was found to be beneficial.
