Fetch Similar
This section describes what is "Fetch Similar" within the platform
It is often required to get similar samples to a given selection to complete an analysis, or test an hypothesis within the platform. For instance, if a subset of the reviewed samples is consistently failing and appears to share a common characteristic - such as a specific lighting condition or the presence of a particular object -retrieving similar samples can help validate whether that characteristic is indeed contributing to the failures.
The "Fetch Similar" provides similar samples to selected samples from the population exploration or the sample analysis. The similar samples could be taken from a slice of the data, defined by filters.
Fetch similar from population exploration

Once samples has been selected from the population exploration, we could use the "Fetch Similar" button to retrieve similar samples. The computed result would be added as a special filter to the population exploration, resulting in only the most similar samples presented.
Fetch Similar from sample analysis

Given a selection of samples in the sample analysis dashlet, similar samples could also be retrieved. This would create a special global filter, applying the entire dashboard to only contain these similar samples.
Notice that it is sometimes required to examine only one slice (i.e. train), but to fetch similars from an disjoint slice (i.e. unlabeled). Such an action would disable all pre-existing filters from the dashlet, to ensure the fetch similar filter is not in contradiction with existing filters.
