Table 1 Settings for LCM in each step
From: Latent class model with application to speaker diarization
Step | Prior setting | Factorized objective function | To be updated |
|---|---|---|---|
1 | \( p(\mathcal {X}_{m}, \mathcal {Y}_{s})\) | \({\sum \nolimits }_{m=1}^{M} \log {\sum \nolimits }_{s=1}^{S} p(\mathcal {X}_{m}, \mathcal {Y}_{s}) q_{{ms}} \) | q ms |
2 | \(\mathcal {X}_{m}, q_{{ms}}\) | \({\sum \nolimits }_{m=1}^{M} \log {\sum \nolimits }_{s=1}^{S} q_{{ms}} p(\mathcal {X}_{m}| \mathcal {Y}_{s}, i_{{ms}}) p(\mathcal {Y}_{s}) \) | \(\mathcal {Y}_{s}\) |
3 | \(\mathcal {X}_{m},q_{{ms}},\mathcal {Y}_{s}\) | \({\sum \nolimits }_{m=1}^{M} \log {\sum \nolimits }_{s=1}^{S} q_{{ms}} p(\mathcal {Y}_{s}|\mathcal {X}_{m}, i_{{ms}}) p(\mathcal {X}_{m}) \) | \( p(\mathcal {X}_{m}, \mathcal {Y}_{s}|i_{{ms}})\) |
