ScVI is a variational inference model for single-cell RNA-seq data that can learn an underlying
|
18 |
+
latent space, integrate technical batches and impute dropouts.
|
19 |
+
The learned low-dimensional latent representation of the data can be used for visualization and
|
20 |
+
clustering.
|
21 |
+
|
22 |
+
scVI takes as input a scRNA-seq gene expression matrix with cells and genes.
|
23 |
+
We provide an extensive [user guide](https://docs.scvi-tools.org/en/1.2.0/user_guide/models/scvi.html).
|
24 |
|
25 |
+
- See our original manuscript for further details of the model:
|
26 |
+
[scVI manuscript](https://www.nature.com/articles/s41592-018-0229-2).
|
27 |
+
- See our manuscript on [scvi-hub](https://www.biorxiv.org/content/10.1101/2024.03.01.582887v2) how
|
28 |
+
to leverage pre-trained models.
|
29 |
|
30 |
+
This model can be used for fine tuning on new data using our Arches framework:
|
31 |
+
[Arches tutorial](https://docs.scvi-tools.org/en/1.0.0/tutorials/notebooks/scarches_scvi_tools.html).

# Model Description
|
35 |
+
|
36 |
+
Tabula Sapiens is a benchmark, first-draft human cell atlas of nearly 500,000 cells from 24 organs of 15 normal human subjects.

# Metrics
|
39 |
+
|
40 |
+
We provide here key performance metrics for the uploaded model, if provided by the data uploader.

42 |
+
<details>
|
43 |
+
<summary><strong>Coefficient of variation</strong></summary>
|
44 |
+
|
45 |
+
The cell-wise coefficient of variation summarizes how well variation between different cells is
|
46 |
+
preserved by the generated model expression. Below a squared Pearson correlation coefficient of 0.4
|
47 |
+
, we would recommend not to use generated data for downstream analysis, while the generated latent
|
48 |
+
space might still be useful for analysis.
|

+

+
**Cell-wise Coefficient of Variation**:

| R² (R-Squared) | 0.60 | 0.50 |
|
58 |

|

The gene-wise coefficient of variation summarizes how well variation between different genes is
|
60 |
+
preserved by the generated model expression. This value is usually quite high.

<summary><strong>Differential expression metric</strong></summary>
|
75 |

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
|
78 |

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
