Struct TimestampSplit

#[non_exhaustive]
pub struct TimestampSplit {
    pub training_fraction: f64,
    pub validation_fraction: f64,
    pub test_fraction: f64,
    pub key: String,
    /* private fields */
}

Assigns input data to training, validation, and test sets based on a provided timestamps. The youngest data pieces are assigned to training set, next to validation set, and the oldest to the test set.

Supported only for tabular Datasets.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

training_fraction: f64

The fraction of the input data that is to be used to train the Model.

validation_fraction: f64

The fraction of the input data that is to be used to validate the Model.

test_fraction: f64

The fraction of the input data that is to be used to evaluate the Model.

key: String

Required. The key is a name of one of the Dataset’s data columns. The values of the key (the values in the column) must be in RFC 3339 date-time format, where time-offset = "Z" (e.g. 1985-04-12T23:20:50.52Z). If for a piece of data the key is not present or has an invalid value, that piece is ignored by the pipeline.

Implementations

impl TimestampSplit

pub fn new() -> Self

pub fn set_training_fraction<T: Into<f64>>(self, v: T) -> Self

Sets the value of training_fraction.

pub fn set_validation_fraction<T: Into<f64>>(self, v: T) -> Self

Sets the value of validation_fraction.

pub fn set_test_fraction<T: Into<f64>>(self, v: T) -> Self

Sets the value of test_fraction.

pub fn set_key<T: Into<String>>(self, v: T) -> Self

Sets the value of key.

Trait Implementations

impl Clone for TimestampSplit

fn clone(&self) -> TimestampSplit

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TimestampSplit

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TimestampSplit

fn default() -> TimestampSplit

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TimestampSplit

where TimestampSplit: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for TimestampSplit

fn typename() -> &'static str

The typename of this message.

impl PartialEq for TimestampSplit

fn eq(&self, other: &TimestampSplit) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for TimestampSplit

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
