 # Machine Learning and Anomaly Detection
 
-Netdata provides a variety of Machine Learning features to help you troubleshoot certain scenarios that might come up.
+Netdata provides advanced Machine Learning features to help you identify and troubleshoot anomalies and unexpected behavior in your infrastructure before they become critical issues:
 
-- K-means clustering [Machine Learning models](/src/ml/README.md) are trained to power the [Anomaly Advisor](/docs/dashboards-and-charts/anomaly-advisor-tab.md) on the dashboard, which allows you to identify anomalies in your infrastructure
-- [Metric Correlations](/docs/metric-correlations.md) are possible through the dashboard using the [Two-sample Kolmogorov Smirnov](https://en.wikipedia.org/wiki/Kolmogorov%E2%80%93Smirnov_test#Two-sample_Kolmogorov%E2%80%93Smirnov_test) statistical test and Volume heuristic measures
-- The [Netdata Assistant](/docs/netdata-assistant.md) is able to answer your prompts when it comes to troubleshooting alerts and anomalies.

 # Working with Logs
 
-This section talks about ways Netdata collects and visualizes logs, while also providing useful guides on log centralization setups that can be used with Netdata.
+This section talks about ways Netdata collects and visualizes logs.
+
+The [systemd journal plugin](/src/collectors/systemd-journal.plugin/) is the core Netdata component for reading systemd journal logs.
+
+For structured logs, Netdata provides tools like [log2journal](/src/collectors/log2journal/README.md) and [systemd-cat-native](/src/libnetdata/log/systemd-cat-native.md) to convert them into compatible systemd journal entries.
+
+You can also find useful guides on how to set up log centralization points in the [Observability Cetralization Points](/docs/observability-centralization-points/README.md) section of our docs.
