17
+ 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).

  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.
41
+
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.
49
+
50
+ **Cell-wise Coefficient of Variation**:
51
+
52
+ | Metric | Training Value | Validation Value |
53
+ |-------------------------|----------------|------------------|
54
+ | Mean Absolute Error | 1.50 | 1.68 |
55
+ | Pearson Correlation | 0.86 | 0.83 |
56
+ | Spearman Correlation | 0.88 | 0.84 |
57
+ | R² (R-Squared) | 0.65 | 0.58 |
58
+
59
+ 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.
61
+
62
+ **Gene-wise Coefficient of Variation**:
63
+
64

65

66

67

74
+ <summary><strong>Differential expression metric</strong></summary>
75
+
76
+ The differential expression metric provides a summary of the differential expression analysis
77
+ 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
79
+ Recall Curve (AUPRC) for the differential expression analysis using Wilcoxon Rank Sum test for each
80
+ cell-type.
