Identification of concurrently broadcast time-based media
A real time messaging platform identifies an audio snippet of a time-based media (TBM) event. The messaging platform maintains a real time repository of concurrently broadcasting TBM events as well as a historical repository of previously broadcast TBM events. These repositories contain acoustic fingerprints of their respective TBM events. The messaging platform matches an acoustic fingerprint of the audio snippet with one of the stored acoustic fingerprints to identify the TBM event in the recorded snippet. To identify the TBM event, the messaging platform matches multiple overlapping reference audio segments of the reference audio stream with multiple test audio segments of the audio snippet. This allows the platform to account for time delays between the test and reference audio segments that would otherwise hinder the matching process. |

Vectorized hash tables
Techniques are described herein for a vectorized hash table that uses very efficient grow and insert techniques. A single-probe hash table is grown via vectorized instructions that split each bucket, of the hash table, into a respective upper and lower bucket of the expanded hash table. Further, vacant slots are indicated using a vacant-slot-indicator value, e.g., ‘0’, and all vacant slots follow to the right of all occupied slots in a bucket. A vectorized compare instruction determines whether a value is already in the bucket. If not, the vectorized compare instruction is also used to determine whether the bucket has a vacant slot based on whether the bucket contains the vacant-slot-indicator value. To insert the value into the bucket, vectorized instructions are used to shift the values in the bucket to the right by one slot and to insert the new value into the left-most slot. |

Generating digital media clusters corresponding to predicted distribution classes from a repository of digital media based on network distribution history
The present disclosure relates to systems, non-transitory computer-readable media, and methods for generating accurate digital media clusters corresponding to predicted distribution classes from a repository of digital media based on network distribution history. For example, a digital media clustering system can apply machine learning models at a remote server (based on network distribution history of a network account of a user) to generate predicted distribution classes for future electronic communications. The remote server can provide the predicted distribution classes to a user client device for secure local analysis of digital media stored at the client device. Based on the predicted distribution classes and the stored digital media, the client device can suggest digital media items to distribute via a networking system. Thus, the disclosed system can surface digital media content without providing any information regarding the digital media items stored at the client device to a remote server. |
