CondSCVI is a variational inference model for single-cell RNA-seq data that can learn an underlying
latent space. The predictions of the model are meant to be afterward
used for deconvolution of a second spatial transcriptomics dataset in DestVI. DestVI predicts the
cell-type proportions as well as cell type-specific activation state
in the spatial data.

CondSCVI takes as input a scRNA-seq gene expression matrix with cells and genes as well as a
cell-type annotation for all cells.
We provide an extensive [user guide](https://docs.scvi-tools.org/en/stable/user_guide/models/destvi.html)
for DestVI including a description of CondSCVI.

# Model Description

Tabula Sapiens is a benchmark, first-draft human cell atlas of nearly 500,000 cells from 24 organs of 15 normal human subjects.

# Metrics

We provide here key performance metrics for the uploaded model, if provided by the data uploader.

<details>
<summary><strong>Coefficient of variation</strong></summary>

The cell-wise coefficient of variation summarizes how well variation between different cells is
preserved by the generated model expression. Below a squared Pearson correlation coefficient of 0.4
, we would recommend not to use generated data for downstream analysis, while the generated latent
space might still be useful for analysis.

**Cell-wise Coefficient of Variation**:

Not provided by uploader

The gene-wise coefficient of variation summarizes how well variation between different genes is
preserved by the generated model expression. This value is usually quite high.

**Gene-wise Coefficient of Variation**:

<details>
<summary><strong>Differential expression metric</strong></summary>

The differential expression metric provides a summary of the differential expression analysis
between cell types or input clusters. We provide here the F1-score, Pearson Correlation
Coefficient of Log-Foldchanges, Spearman Correlation Coefficient, and Area Under the Precision
Recall Curve (AUPRC) for the differential expression analysis using Wilcoxon Rank Sum test for each
cell-type.
