Hi, According to the manual of Moses, the MERT only tunes the weights for the following 4 components: 1. phrase translation 2. language model 3. distortion model 4. word penalty
where the phrase translation can be decomposed into the following: 1.1. P(f|e) 1.2. P(e|f) 1.3. Pw(f|e) 1.4. Pw(e|f) 1.5. phrase-penalty: exp(-1) It seems Moses won't assign a separate weight to each individual components 1.1-1.5 above, instead it will assign a single weight to the combined component "phrase translation". Am I right? In other words, Moses assumes the same weight should get assigned to all the 5 components above? Was the same done by Pharaoh also? -- best, Wei Sent from Singapore
