In this project some limitations have been imposed in the procedures
followed in testing and specially in training. Some such limitations, and
their effects are listed below.
- The training data base was limited to 100 sentences. This has an
undesirable effect on generalization properties, and significance of
estimated parameters. A larger data base, at least the TIMIT
462-sentence training set can be used instead.
- Number of training epochs was limited to 100. Clearly we have
risk that training has been stopped, before reaching a dominating
local minimum. We can increase the number of epochs, sacrificing the
training time. Precautions must be taken to avoid over training.
- Whole training set was considered as a single batch. This leads
to a less stochastic search path in the weight space and hence a
more chance to be stuck in to a local minimum. This can be avoided
by dividing the training set into several batches, and by operating on
this sequence of batches
