The disclosed embodiments relate generally to media provider systems including, but not limited to, systems and methods for discovering and recommending media to users.
Recent years have shown a remarkable growth in consumption of digital goods such as digital music, movies, books, and podcasts, among many others. The overwhelmingly large number of these goods often makes navigation and discovery of new digital goods an extremely difficult task. Recommender systems commonly retrieve preferred items for users from a massive number of items by modeling users' interests based on historical interactions. However, reliance on historical interaction data is limiting for user exploration and item discovery. This problem is further aggravated for the discovery of novel or cold-start items.
Recommender Systems (RS) are applied to web applications to retrieve relevant information. Recommender Systems can provide personalized recommendations of items to alleviate information overload for users, e.g., recommendations for audio streaming and online shopping. Collaborative filtering (CF) is employed by some Recommender Systems and assumes that users with similar interests prefer similar items. For example, with CF the users' interests are modeled or optimized by historical interactions. CF systems can embed users and items as latent representation vectors, with features as inputs (e.g., either pure IDs or pre-processed feature vectors).
However, because CF-based Recommender Systems model interest based on historical interactions, these systems may fail to identify topics that users would be interested in but may not know about (e.g., have no prior historical interaction). Therefore, a challenge for RS is to facilitate user exploration. Exploration is increasingly a problem in RS, as existing RS methods can cause echo chambers and filter bubbles as users increasingly engage with RS. This phenomenon may optimize short-term user interests and can fail to drive long-term user engagement. A lack of diversity of recommended items can also reduce user satisfaction.
New and diverse podcast content is increasingly and continuously being created. However, user exploration of new podcasts has several challenges, including feature sparsity and interaction sparsity. These challenges can result from a data sparsity problem in RS, where limited interaction data is available for representing users and items. Specifically, feature sparsity can be due to many podcasts being cold-start items with few user interactions. Additionally, a lack of user-item interaction is inherent in recommending new content to users.
The disclosed embodiments include a recommendation system to assist users with episode discovery for podcasts and other media. Episode discovery involves a user interacting with an episode from a podcast with which the user has never before interacted. Some conventional recommendation systems rely on historical user-interactions and therefore have a sparsity problem when recommending new shows (e.g., cold-start items) with few user interactions (e.g., an inherently small training set). For example, the new shows may have 10 or less positive interactions. A positive interaction can include a user listening for at least a preset amount of time (e.g., 30 seconds, 1 minute, or 2 minutes). The recommendation system described herein uses (i) a two-tower model, and (ii) a contrastive learning approach to improve performance and help users discover new shows in accordance with some embodiments. For example, a two-tower model determines a latent similarity between a user embedding and an episode embedding. A contrastive learning approach can include feature-level augmentation (e.g., feature dropout layer(s)) to obtain augmented episode embeddings. The contrastive learning approach can also include instance-level augmentation (e.g., identifying similar episodes using semantics, cosine similarity, and/or knowledge graph information) to obtain correlated episode embeddings. Thus, the contrastive learning approach can increase the size of the training set for the two-tower model (e.g., to overcome the sparsity problem).
In accordance with some embodiments, a method of recommending content to a user is provided. The method is performed at a computing device having one or more processors and memory. The method includes: (1) obtaining a pre-trained recommender model, where the pre-trained recommender model is trained using contrastive learning with feature-level augmentation and instance-level augmentation; (2) generating, via the pre-trained recommender model, a user embedding based on a plurality of features of the user; (3) generating, via the pre-trained recommender model, a respective episode embedding for each episode of a plurality of episodes, each respective episode embedding based on a plurality of features of the corresponding episode; (4) generating, via the pre-trained recommender model, a respective similarity score for each episode of a plurality of episodes, the respective similarity score corresponding to a latent similarity between the user embedding and each respective episode embedding; (5) ranking the plurality of episodes in accordance with the respective similarity scores; and (6) recommending a highest ranked episode of the plurality of episodes to the user.
In accordance with some embodiments, an electronic device is provided. The electronic device includes one or more processors and memory storing one or more programs. The one or more programs include instructions for performing any of the methods described herein (e.g., the method 700).
In accordance with some embodiments, a non-transitory computer-readable storage medium is provided. The non-transitory computer-readable storage medium stores one or more programs for execution by an electronic device with one or more processors. The one or more programs comprising instructions for performing any of the methods described herein (e.g., the method 700).
Thus, methods and systems are disclosed that identify and recommend content and media to users. Such methods and systems may complement or replace conventional methods and systems of identifying and recommending content and media to users.
The embodiments disclosed herein are illustrated by way of example, and not by way of limitation, in the figures of the accompanying drawings. Like reference numerals refer to corresponding parts throughout the drawings and specification.
Reference will now be made to embodiments, examples of which are illustrated in the accompanying drawings. In the following description, numerous specific details are set forth in order to provide an understanding of the various described embodiments. However, it will be apparent to one of ordinary skill in the art that the various described embodiments may be practiced without these specific details. In other instances, well-known methods, procedures, components, circuits, and networks have not been described in detail so as not to unnecessarily obscure aspects of the embodiments.
The disclosed embodiments include a two-tower recommender framework with contrastive learning to improve recommendations for discovery and exploration. Contrastive learning involves learning to compare items and can be used to enhance an encoder network. In some embodiments, two types of contrastive learning are combined: feature augmentation using feature drop-out during training, and instance-level augmentation. For example, feature augmentation for images may include rotation, color changes, cropping, and the like. For instance-level augmentation, semantic similarity between episodes can be used (e.g., using cosine-similarity between pre-trained embeddings of episodes) to assist the model in learning which episodes are similar to one another and help users to discover items that are semantically similar to their past listening.
Some embodiments include a framework (e.g., a two-tower architecture) with hierarchical data augmentations in contrastive learning. Data augmentation enriches data with different views of similar items (e.g., for learning item embeddings), and contrastive learning acts as a bridge connecting augmented items and positively interacted items. In accordance with some embodiments, the disclosed framework incorporates a feature level augmentation (e.g., fine granularity) and an instance level augmentation (e.g., coarse granularity). For feature level augmentation, a feature dropout technique to randomly mask a subset of item features can be used so that some sparse features are trained to better infer the item embedding. For instance level augmentation, similar items from different semantic item relationships are incorporated as positive items to enrich scarce user-item interactions. Thus, in accordance with some embodiments, a data augmentation framework is disclosed to alleviate data sparsity in user exploration and recommendation from two perspectives: (1) feature augmentation for feature sparsity, and (2) instance augmentation for user-item explorative interactions sparsity.

Furthermore, memory 212 and 306 optionally store additional modules and data structures not described above.
Although
The other path includes obtaining episode features 510 (e.g., an episode feature vector) for each episode of one or more episodes 508. In some embodiments, the episode features 510 include one or more of: episode topic, episode title, episode genre, and episode consumption data. In some embodiments, the episode features for a podcast include one or more of: topics, country, collaborative filtering pre-trained embeddings, and pre-trained semantic embeddings of the podcast. A respective episode embedding 512 is generated from each set of episode features 510. In some embodiments, an MLP or feedforward ANN is used for episode feature 510 transforms. A similarity score 514 (e.g., a preference score) is generated for the user embedding 506 and each episode embedding 512. In some embodiments, for discrete features, the features are encoded as one-hot or multi-hot vectors. In some embodiments, for continuous features, such as pre-trained embedding vectors, the features are input directly. In some embodiments, after encoding, all of the features for the user are concatenated and all of the features for the episode are concatenated.
In accordance with some embodiments, an episode exploration recommender rui (e.g., a two-tower model) is defined by:
=Fu(fu)TFi(fi) Equation 1: Exploration Recommender
where u denotes a user in a user set U and i denotes an episode in an episode set I. In some embodiments, the episode i belongs to a podcast show p, where p belongs to a set of podcast shows P. In Equation 1, the vector fu represents a user feature vector and the vector fi represents an episode feature vector. Fu and Fi in Equation 1 represent neural networks for learning user embeddings and episode embeddings. In some embodiments, an episode exploration recommendation list is generated by ranking the rui on all episodes (e.g., in descending order).
In some embodiments, the neural networks Fu and Fi are defined by:
F
u
L=ReLU(FuL−1W1L+b1L)
F
i
L=ReLU(FiL−1W2L+b2L) Equations 2: User and Episode Neural Networks
where ReLU( ) represents a rectified linear unit (ReLU) activation function, W*L represents a linear transformation, and b*L represents a bias. For example, the 0-th layer of each tower is the input feature vector of fu and fi respectively. In some embodiments, the last layer output embedding is used to make predictions, e.g., as in Equation 1 above. In some embodiments, the neural networks in Equations 2 are L-th layers fully connected neural networks.
In some circumstances, contrastive learning maximizes the alignment between two views of one instance (e.g., a positive pair). The construction of the positive pair (e.g., type of data augmentation) varies. For example, injecting noise in the input data to create different views or jointly modeling multi-modal information from the same object. With the advantage of data augmentation, contrastive learning improves over zero-shot (e.g., zero or limited data for predicting classes) settings, which is similar to a cold start scenario in recommender systems with each item viewed as a class. The frameworks in
In a cold start scenario, features specific to cold episodes have limited interactions and optimization opportunities for cold features may not be well trained. In some embodiments, a subset of input features is randomly masked to enforce the model capability of learning without popular features (e.g., to alleviate cold start issues). In some situations, this masking helps the model generate accurate recommendations with cold features.
In some situations, in addition to feature level augmentation, the scarcity of user-episode interactions is a significant component of recommendation for discovery and exploration. Some embodiments include generating positive episodes from additional item similarity semantic relationships, including episodes with similar text content and episodes with similar knowledge information. In some embodiments, a user is assumed to be more likely to explore new items with similar content or correlated knowledge to items they have interacted with in the past.
In some embodiments, for each episode i, pre-trained content embeddings and knowledge embeddings are used as side information. In some embodiments, the content embeddings are pre-trained with the episode script and title text. In some embodiments, the knowledge embeddings are pre-trained from episode knowledge graph data. In some embodiments, an Approximate Nearest Neighbors lookup with Annoy architecture is used to extract the top-K similar episodes from each semantic relationship. In some embodiments, top-K similar episodes are extracted by ranking the top-K episodes (e.g., the top 10, 20, or 30 episodes) with smallest L2 distances on content embeddings or knowledge embeddings, respectively.
In some embodiments, positive episodes are generated either from feature dropout, similar semantic relationships, or both. In some embodiments, given a batch of N user-episode exploration interactions, one positive episode is augmented (e.g., an augmented episode is generated) for each episode. In this way, 2N episodes are obtained and a pairing of episodes and augmented episodes results in one positive pair and 2(N−1) negative pairs. In some embodiments, for each episode pair, and the pair features, learned embeddings are obtained after L-layers of the episode tower. In some embodiments, the loss for optimization is defined as:
where (Fi
In some embodiments, a sampled softmax cross-entropy loss function is used as the user-episode exploration interaction optimization, which incorporates the contrastive loss in Equation 3 as regularization. In accordance with some embodiments, the softmax cross-entropy loss function is defined as:
where k negative items are sampled in interactions optimization.
The system obtains (702) a pre-trained recommender model, where the pre-trained recommender model is trained using contrastive learning with feature-level augmentation (e.g., as illustrated in
In some embodiments, the pre-trained recommender model is (704) a two-tower model having a user function and an episode function (e.g., the framework 500 illustrated in
In some embodiments, the feature-level augmentation includes (706) generating augmented episode embeddings by masking subsets of the plurality of features of the corresponding episodes (e.g., using the augmenter(s) 328). For example, the augmented episode embedding 608 is generated by masking subsets of the episode features 510 of the corresponding episode (e.g., using the dropout layer 604).
In some embodiments, the instance-level augmentation includes (708) identifying a correlated episode (e.g., the correlated episode 612) for an episode of the plurality of episodes and generating a correlated episode embedding (e.g., the correlated episode embedding 618) for the correlated episode (e.g., using the augmenter(s) 328).
In some embodiments, generating the correlated episode embedding includes (710) applying a feature-level augmentation to the features of the correlated episode (e.g., the dropout layer 614).
In some embodiments, the correlated episode is identified (712) using a semantic similarity approach (e.g., using a transformer model such as BERT). In some embodiments, the correlated episode is identified (714) using a knowledge graph similarity approach. In some embodiments, the correlated episode is identified (716) using a cosine similarity approach. For example, the correlated episode is identified as described previously with respect to
The system generates (718), via the pre-trained recommender model, a user embedding (e.g., the user embedding 506) based on a plurality of features of the user. In some embodiments, the plurality of features of the user includes (720) one or more of: a gender, an age, a country, a language, a recent topic liked, a streaming statistic, and a collaborative filtering vector.
The system generates (722), via the pre-trained recommender model, a respective episode embedding (e.g., the episode embedding 512) for each episode of a plurality of episodes, each respective episode embedding based on a plurality of features of the corresponding episode. In some embodiments, the plurality of features of the episode includes (724) one or more of: a topic, a country, a language, a licensor, a publisher, a collaborative filtering vector, and a semantic embedding.
The system generates (726), via the pre-trained recommender model, a respective similarity score (e.g., the similarity score 514) for each episode of a plurality of episodes, the respective similarity score corresponding to a latent similarity between the user embedding and each respective episode embedding.
In some embodiments, the plurality of episodes consists of (728) episodes with which the user has not previously interacted (e.g., discovery episodes that the user has not interacted with previously).
The system ranks (730) the plurality of episodes in accordance with the respective similarity scores. For example, the system ranks respective similarity scores 514 using the ranker 329.
The system recommends (732) a highest ranked episode of the plurality of episodes to the user. For example, the media content server 104 and/or the electronic device 102 recommend a highest ranked discovery episode to a user of the electronic device 102.
