1. very initial, without any prunning, character based. Here is the size and perplexity.
The training is with Gigabytes except the cna data, and ppl testing is based on a sub set from the cna data (big52gb applied)
2gram:
25M 2gram.4000.gz: 0 zeroprobs, logprob= -9.39983e+06 ppl= 161.965 ppl1= 177.141
3gram:
47M 3gram.500.gz:0 zeroprobs, logprob= -6.34868e+06 ppl= 85.1361 ppl1= 94.2525
117M 3gram.1000.gz :0 zeroprobs, logprob= -7.43809e+06 ppl= 80.6408 ppl1= 87.7439
195M 3gram.2000.gz:0 zeroprobs, logprob= -7.95872e+06 ppl= 79.9875 ppl1= 86.5196
221M 3gram.3000.gz:0 zeroprobs, logprob= -8.04799e+06 ppl= 80.2418 ppl1= 86.7277
229M 3gram.4000.gz:0 zeroprobs, logprob= -8.15697e+06 ppl= 82.6585 ppl1= 89.3392
4gram:

2. pruning the 4k 3gram LM.
| Model | 2gram | 3gram | size | ppl |
|---|---|---|---|---|
| 1 | 1e-7 | 1e-7 | 30M logprob= -8.55982e+06 ppl= 102.796 ppl1= 111.532 | |

3. word-based 3-gram
tri-gram size:
| org | th-7 | th-7/6 | th-6 |
| 10k: 52M | 23M | 8M | 4M |
| 20k: 57M | 24M | 9M | 4M |
final fst size:
| org | th-7 | th-7/6 | th-6 |
| 10k: - | 770M | 193M | 135M |
| 20k: - | - | - | - |
