Struct GraphSageOptions 

pub struct GraphSageOptions {
    pub dimensions: usize,
    pub hidden_dimensions: usize,
    pub layers: usize,
    pub sample_sizes: Vec<usize>,
    pub aggregator: GraphSageAggregator,
    pub epochs: usize,
    pub negative_samples: usize,
    pub learning_rate: f64,
    pub feature_properties: Vec<String>,
    pub seed: u64,
}

Unsupervised GraphSAGE v1 options.

feature_properties must be supplied explicitly: the empty default is not a runnable GraphSAGE configuration.

Fields

dimensions: usize

Output vector width.

hidden_dimensions: usize

Width of non-final layers.

layers: usize

Number of aggregation layers.

sample_sizes: Vec<usize>

Ordered fanout for each layer.

aggregator: GraphSageAggregator

Version-pinned neighborhood aggregator.

epochs: usize

Training epochs.

negative_samples: usize

Negative samples per positive pair.

learning_rate: f64

Constant Adam learning rate.

feature_properties: Vec<String>

Ordered graph-native numeric feature properties.

seed: u64

Caller seed; omission normalizes to zero.
