What is manual clustering?
phy lets you classify, merge, split clusters manually if the output of the automatic spike sorting algorithms are not satisfactory.
Is clustering always unsupervised?
Clustering can be considered the most important unsupervised learning problem; so, as every other problem of this kind, it deals with finding a structure in a collection of unlabeled data. A loose definition of clustering could be “the process of organizing objects into groups whose members are similar in some way”.
What do you need to know about cluster access control?
Cluster access control within the Admin Console allows admins and delegated users to give fine-grained cluster access to other users. There are two types of cluster access control: Cluster creation permission: Admins can choose which users are allowed to create clusters.
What happens when you run a job on a new cluster?
When you run a job on a New Job Cluster (which is usually recommended), the cluster terminates and is unavailable for restarting when the job is complete. On the other hand, if you schedule a job to run on an Existing All-Purpose Cluster that has been terminated, that cluster will autostart.
How can I see the configuration of a cluster?
When you view an existing cluster, simply go to the Configuration tab, click JSON in the top right of the tab, copy the JSON, and paste it into your API call. JSON view is ready-only. You edit a cluster configuration from the cluster detail page. To display the cluster detail page, click the cluster name on the Compute page.
What happens if a cluster is running dstreams?
Clusters do not report activity resulting from the use of DStreams. This means that an autoterminating cluster may be terminated while it is running DStreams. Turn off auto termination for clusters running DStreams or consider using Structured Streaming. The auto termination feature monitors only Spark jobs, not user-defined local processes.
