Struct RuleSpace 

pub struct RuleSpace { /* private fields */ }

👎Deprecated since 0.2.0: Use system::System and SystemBuilder instead

Container for fuzzy variables, rules, and intermediate membership data.

Internally, RuleSpace stores:

• vars: the set of named input/output variables.
• rules: the rule base defining inference behavior.
• agg_memberships: aggregated membership samples per output variable from the most recent call to aggregate/defuzzify.

Implementations

impl RuleSpace

pub fn new(vars: HashMap<String, Variable>, rules: Vec<Rule>) -> Result<Self>

👎Deprecated since 0.2.0: Use system::System and SystemBuilder instead

Create a rule space with the supplied variables and rules.

Errors

• FuzzyError::EmptyInput if vars or rules is empty.

pub fn add_rules(&mut self, rules: &mut Vec<Rule>) -> Result<&mut Self>

👎Deprecated since 0.2.0: Use system::System and SystemBuilder instead

Append additional rules to the existing rule set.

Returns a mutable reference to self upon success.

Errors

• FuzzyError::EmptyInput if rules is empty.

pub fn aggregate<KI>( &mut self, input: &HashMap<KI, Float>, sampler: &UniformSampler, ) -> Result<()>

where KI: Eq + Hash + Borrow<str>,

👎Deprecated since 0.2.0: Use system::System and SystemBuilder instead

Run the aggregation step for all rules with the provided crisp inputs.

This populates agg_memberships with a sample vector for each output variable. Use defuzzify if you want crisp outputs in a single call.

Type parameters

• KI: key type for input, must borrow as str.

Errors

• Propagates errors from rule activation/implication and aggregation.

pub fn defuzzify<KI>( &mut self, input: &HashMap<KI, Float>, sampler: &UniformSampler, ) -> Result<HashMap<String, Float>>

where KI: Eq + Hash + Borrow<str>,

👎Deprecated since 0.2.0: Use system::System and SystemBuilder instead

Aggregate and then defuzzify each output variable using the supplied sampler.

Combines aggregate and defuzzification to return crisp values for all output variables in a single call.

Type parameters

• KI: key type for input, must borrow as str.

Errors

• Propagates any error from aggregation or defuzzification.
