Struct TimeEncoding

pub struct TimeEncoding {
    pub encoding_type: TimeEncodingType,
    pub time_dim: usize,

Expand description

Temporal encoding module that maps scalar timestamps to vector representations.

Supports two encoding types:

Sinusoidal: fixed frequencies at different scales
Time2Vec: learnable linear + periodic components

Fields§

§encoding_type: TimeEncodingType

Encoding type

§time_dim: usize

Output dimension for time encoding

§omega: Array1<f64>

Learnable frequency parameters for Time2Vec: [time_dim]

§phi: Array1<f64>

Learnable phase parameters for Time2Vec: [time_dim]

§linear_weight: f64

Linear component weight for Time2Vec

§linear_bias: f64

Linear component bias for Time2Vec

Implementations§

Source §

impl TimeEncoding

Source

pub fn new(time_dim: usize, encoding_type: TimeEncodingType) -> Self

Source

pub fn encode(&self, t: f64) -> Array1<f64>

Encode a single timestamp.

§Arguments

t - Scalar timestamp

§Returns

Time encoding vector of length time_dim

Source

pub fn encode_batch(&self, timestamps: &[f64]) -> Array2<f64>

Encode multiple timestamps.

§Arguments

timestamps - Slice of timestamps

§Returns

Matrix [len, time_dim] of time encodings
