Recognition Version

Version object

Definition

A recognition version implements a specification: this is the link between a specification and a neural network.

AttributeTypeAttributesDescription

id

int

read-only

The ID of the recognition version.

spec_id

int

immutable

The ID of the parent recognition specification.

network_id

int

immutable

The ID of the neural network which will cary on the computation.

post_processings

immutable

The post-processing object that defines some network specific adjustments like the output tensor, some thresholds, etc. The length of this array must exactly match the length of the outputs field of the parent specification and the i-th post-processing will be matched to the i-th output.

spec_name

string

read-only

The name of the recognition specification corresponding to spec_id. This is convenient for display purposes.

network_name

string

read-only

The name of the neural network corresponding to network_id. This is convenient for display purposes.

update_date

string

read-only

Date time (ISO 8601 format) of the creation specification version.

Post-processing

The fields of this object are mutually exclusive: you must specify exactly one of them.

AttributeTypeDescription

classification

A post-processing of type classification for an output of type labels.

detection

A post-processing of type detection for an output of type labels.

Classification post-processing

AttributeTypeDescription

thresholds

array(float)

A list of threshold for each label of the recognition specification. The label will be considered present if its score is greater than the threshold. The length of this array must exactly match the length of the labels field of the parent labels specification and the i-th threshold will be matched to the i-th label.

Detection post-processing

You must specify exactly one of the anchored_output, direct_output or yolo_output fields. When we specify an expected tensor size in the description of those fields, we omit the first dimension of the tensor (i.e. the batch size).

AttributeTypeDescription

thresholds

array(float)

A list of threshold for each label of the recognition specification. The label will be considered present if its score is greater than the threshold. The length of this array must exactly match the length of the labels field of the parent labels specification and the i-th threshold will be matched to the i-th label.

nms_threshold

float

The Jaccard index threshold that will be applied to NMS to decide if two boxes of the same label represent the same object.

Definition

Creates a new recognition version.

Arguments

ParameterTypeDefaultDescription

spec_id

int

The ID of the parent recognition specification.

network_id

int

The ID of the neural network which will cary on the computation.

post_processings

The post-processing object that defines some network specific adjustments like the output tensor, some thresholds, etc. The length of this array must exactly match the length of the outputs field of the parent specification and the i-th post-processing will be matched to the i-th output.
