Abstract: Snippets can be represented in a language-independent semantic manner. Each portion of a snippet can be represented by a combination of a semantic representation and a syntactic representation, each in its own dimensional space. A snippet can be divided into portions by constructing a dependency structure based on relationships between words and phrases. Leaf nodes of the dependency structure can be assigned: A) a semantic representation according to pre-defined word mappings and B) a syntactic representation according to the grammatical use of the word. A trained semantic model can assign to each non-leaf node of the dependency structure a semantic representation based on a combination of the semantic and syntactic representations of the corresponding lower-level nodes. A trained syntactic model can assign to each non-leaf node a syntactic representation based on a combination of the syntactic representations of the corresponding lower-level nodes and the semantic representation of that node.

Abstract: This disclosure provides methods, devices and systems for selecting a first group of wireless communication devices to receive a first multi-user (MU) protocol data unit (PDU). A threshold value for identifying collisions of PDUs is determined based on the number of devices in the first group of devices. A second group of wireless communication devices is selected to receive a second MU PDU. Responsive to determining that an acknowledgment (ACK) acknowledging the second MU PDU has not been received from a device of the second group of devices within a threshold duration of time, a number of ACKs, including the ACK, that have not been received from the respective device is determined. An action is then performed based on the determined number of ACKs and the threshold value. In some implementations, the action includes reducing a data rate or initiating a backoff operation.
