Construction¶

RecurrentMatcher(
    const Output<Node>& initial_pattern,
    const Output<Node>& pattern,
    const std::shared_ptr<Node>& rpattern,
    const std::set<std::shared_ptr<Node>>& correlated_patterns
    )

Constructs a RecurrentMatcher object. Reccurent Matchers are used to match repeating patterns (e.g. RNN, LSTM, GRU cells)

Parameters:

initial_pattern	is a pattern sub graph describing the initial cell
pattern	is a pattern sub graph describing an individual cell
rpattern	is a (recurring) label to denote which node the next match should start at
correlated_patterns	is a set of labels whose bound nodes must remain the same across all cells

RecurrentMatcher(
    const Output<Node>& pattern,
    const std::shared_ptr<Node>& rpattern,
    const std::set<std::shared_ptr<Node>>& correlated_patterns
    )

Constructs a RecurrentMatcher object. Reccurent Matchers are used to match repeating patterns (e.g. RNN, LSTM, GRU cells)

Parameters:

pattern	is a pattern sub graph describing an individual cell
rpattern	is a (recurring) label to denote which node the next match should start at
correlated_patterns	is a set of labels whose bound nodes must remain the same across all cells

Methods¶

NodeVector get_bound_nodes_for_pattern(const std::shared_ptr<Node>& pattern) const

Returns a vector of bound nodes for a given label (used in a pattern describing an individual cell.

bool match(Output<Node> graph)

Tries to match a pattern for an individual cell to a given graph.
