Current

The Current section stores all the information (statistics, model metrics and charts) related to the current dataset, placed side-by-side to the reference ones. The objective is to streamline and highlight every difference between the data over time. Throughout the platform, all the current information is coloured blue or in different shades.

NOTE: in this section, you will always see the last uploaded current dataset. In case you need previous current analysis, you can browse among them in the Import section.

Data Quality​

The Data Quality dashboard contains a descriptive analysis of the current variables (blue) placed side-by-side with the reference ones (grey). It adapts itself accordingly to the Model Type and shows information such as:

  • Number of observations
  • Number of classes (not in regression task)
  • Ground Truth Distribution
  • Histograms for Numerical Features
  • Descriptive Statistics for Numerical Features (average, standard deviation, ranges, percentiles, missing values)
  • Bar Charts for Categorical Features
  • Descriptive Statistics for Categorical Features(missing values, distinct values, frequencies)

Model Quality​

The Model Quality dashboard contains all the metrics used to evaluate the model performance in the current dataset and compare these values to the reference. Many of them are computed through the prediction/probability compared to the ground truth. Naturally, the platform computes the proper metrics according to the chosen Model Type.
Differently from the reference section, here, the metrics are computed over time thanks to the flagged timestamp columns and the granularity parameter chosen during the model creation.

Data Drift​

The Data Drift section contains the outcome of some drift detector executed for each variable. According to the field type (categorical or numerical), a specific drift is computed:

  • Categoricals: Chi-Square Test
  • Numerical: 2-Samples-KS Test (for float variables), PSI (for int variables)

If the dot placed at the side of the variable name is red, it means that a drift has been revealed and the relative chart (and statistical description) can be seen in the Current/Data Quality section.

Import​

The Import section lists the path where your current CSVs are stored. If you have a private AWS, the files will be saved in a dedicated S3 bucket otherwise, they will be saved locally with Minio (which shares the same syntax as S3). To see your current datasets stored in Minio, visit the address http://localhost:9091.

Here, you can browse between all the current datasets you have uploaded over time.
