Bulk Batch Results
When a bulk batch file is submitted to the API a single response file is returned. The response includes a record for each submitted observation, which includes the submitted observation and the API response for each observation. Response records are in the same order as the originally submitted observation data.
Response Value – Novelty Score
The score is the total calculation of how novel the particular observation is. The value is always between 0 and 1, where zero is entirely normal and not-anomalous, and one is highly novel and clearly anomalous. The score is the result of a complex analysis of the observation and other contextual data. In contrast to the next field, this score is weighted primarily by the novelty of individual components of the observation. Depending on the dataset and corresponding observation structure (see Step 2), real-world datasets will often see this score weighted with exponentially fewer results at higher scores. Practically, this often means that 0.99 is a reasonable threshold for finding only the most anomalous results; and 0.999 is likely to return half as many results. But to reiterate, the actual values and results will depend on the data and observation structure.
Response Value – Most Novel Component
Which component in the list from the observation field was the most novel. This value is the index into that list, and is zero-indexed.
Response Value – Info Content
The “Information Content”, “Shannon Information”, or “self-information” contained in this entire observation, given all prior observations. This value is measured in bits, and is an answer to the question: On average, how many “yes/no” questions would I need to ask to identify this observation, given this and all previous observations made to the system.
Response Value – Uniqueness
A value between 0 and 1 which indicates how unique this entire observation is, given all previously observed data. A value of 1 means that this observation has never been seen before (in its entirety). Values approaching 0 indicate that this observation is incredibly common.
Response Value - Probability
This field represents the probability of seeing this entire observation (exactly) given all previous data when the observation was made.
