BBC NEWS | Magazine | Three little words so hard to say

A very nice article about knowledge and the ability to admit that you don't know. I cite a piece of the text from the article about the work of politicians.
BBC NEWS | Magazine | Three little words so hard to say: "'I, in the early days, was trying to persuade a minister this was a really important public policy. He said, 'Do you know what? Repeat victimisation's got too many syllables. Can't you think of something with fewer syllables? Could we call it repeat offending?''"

how the make HCL and G graphs, and on the fly compositon of HCL and G for KALDI

Well, I had again to do something ;-) The task is to generate/create/update a decoding graph for KALDI on the fly. In my case, I aim at changing a G (grammar) in the context of a dialogue system. One can generate a new HCLG but this would take a lot of time as this involves FST determinization, epsilon-removal, minimization, etc. Therefore, I tried to use on-the-fly composition of statically prepared HCL and G. At first, I struggled with it but later I made it work. See https://github.com/jpuigcerver/kaldi-decoders/issues/1 Here is a short summary: At the end, I managed to get LabelLookAheadMatcher to work. It is mostly based on the code and examples in opendcd, e.g. https://github.com/opendcd/opendcd/blob/master/script/makegraphotf.sh . First, Here is how I build and prepare the HCL and G. Please not that OpenFST must be compiled with --enable-lookahead-fsts , see http://www.openfst.org/twiki/bin/view/FST/ReadMe . #--------------- fstdeterminize ${lang}/...

Viterbi Algorithm in C++ and using STL

To practice my C++ and STL skills, I implemented the Viterbi algorithm example from the Wikipedia page: http://en.wikipedia.org/wiki/Viterbi_algorithm . The original algorithm was implemented in Python. I reimplemented the example in C++ and I used STL (mainly vector and map classes). This code is in public-domain. So, use it as you want. The complete solution for MS Visual C++ 2008 can be found at http://filip.jurcicek.googlepages.com/ViterbiSTL.rar // ViterbiSTL.cpp : is an C++ and STL implementatiton of the Wikipedia example // Wikipedia: http://en.wikipedia.org/wiki/Viterbi_algorithm#A_concrete_example // It as accurate implementation as it was possible #include "stdafx.h" #include "string" #include "vector" #include "map" #include "iostream" using namespace std; //states = ('Rainy', 'Sunny') // //observations = ('walk', 'shop', 'clean') // //start_probability = {'Rainy': 0.6...
