## Performance

Our CTC implementation is efficient, compared with many of the other implementations publically available.
Our CTC implementation is efficient, compared with many of the other implementations publically available. All calculations are performed in log-space for numerical stability,
we have found cases where this was required while training our Deep Speech models.
We compare our performance with [Eesen](https://github.com/srvk/eesen/commit/68f2bc2d46a5513cce3c232a645292632a1b08f9), as well as with
a CTC implementation built on [Theano](https://github.com/mohammadpz/CTC-Connectionist-Temporal-Classification/commit/904e8c72e15334887609d399254cf05a591d570f).
We benchmark the Theano implementation operating on 32-bit floating-point numbers and doing the calculation in log-space,
