Enum ExistsStrategy 

pub enum ExistsStrategy {
    Sum,
    Max,
    LogSumExp,
    Mean,
}

Strategy for compiling existential quantifiers (∃).

Variants

Sum

Sum reduction: sum(P, axis)

• Soft semantics (counts satisfying instances)
• Differentiable

Max

Max reduction: max(P, axis)

• Hard semantics (true if any instance satisfies)
• Not differentiable at unique maximum

LogSumExp

LogSumExp: log(sum(exp(P), axis))

• Smooth approximation to max
• Differentiable

Mean

Mean reduction: mean(P, axis)

• Normalized soft semantics
• Differentiable

Trait Implementations

impl Clone for ExistsStrategy

fn clone(&self) -> ExistsStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExistsStrategy

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ExistsStrategy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ExistsStrategy

fn eq(&self, other: &ExistsStrategy) -> 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 ExistsStrategy

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
