Abstract

A network system analyzes data samples using embeddings based on, for example, symbolic representations of the data samples or representations in latent dimension space. The network system coordinates providers who provide geographical location-based services to users. The network system may receive data samples from the client device of a provider. For instance, a sensor of the client device captures the data samples during a transportation service along a particular route. To verify that the data samples accurately indicate the location or movement of the provider, the network system can generate a test embedding representing the data samples and compare the test embedding with a reference embedding. The reference embedding is generated based on data samples captured for other similar services, e.g., corresponding to providers who also provided transportation services along the same particular route.

First claim

What is claimed is:

1 . A method for verifying a service for a user and a provider, the method comprising:
receiving, from a client device, a data sample for a set of sensors of the client device, the data sample being associated with the service for the user and the provider, generating a test embedding for the data sample, the test embedding using a plurality of latent dimensions that represent at least a portion of the data sample; determining a similarity score between the test embedding and a reference embedding by comparing each latent dimension of the test embedding and a corresponding latent dimension of the reference embedding; determining, in response to the similarity score exceeding a threshold score, that the provider and the user traveled together along at least a portion of a route of the service; and determining an amount of compensation to be provided from the user to the provider for the service using at least the portion of the route.

2 . The method of claim 1 , wherein the amount of compensation is determined using a distance traveled along the portion of the route.

3 . The method of claim 1 , wherein the amount of compensation is determined using a duration of travel time along the portion of the route.

4 . The method of claim 1 , further comprising:
determining that the data sample indicates that the provider and the user did not travel together along a different portion of the route of the trip, wherein the amount of compensation does not account for the different portion of the route.

5 . The method of claim 1 , further comprising:
determining that a safety incident occurred during the portion of the route.

6 . The method of claim 1 , wherein the portion of the data sample has a duration of time and a different data sample has a different duration of time, the reference embedding determined based at least in part on the different data sample.

7 . The method of claim 1 , wherein the test embedding and the reference embedding are generated using a model trained to infer latent variables based at least in part on feature vectors derived from data samples captured for services, the latent variables associated with the plurality of latent dimensions.

8 . The method of claim 1 , wherein the plurality of latent dimensions includes at least three dimensions.

9 . The method of claim 1 , wherein the similarity score is determined using cosine similarity between the test embedding and the reference embedding.

10 . A computer program product comprising a non-transitory computer readable storage medium having instructions, for verifying a service for a user and a provider, encoded thereon that, when executed by one or more processors, cause the one or more processors to:
receive, from a client device, a data sample for a set of sensors of the client device, the data sample being associated with the service for the user and the provider; generate a test embedding for the data sample, the test embedding using a plurality of latent dimensions that represent at least a portion of the data sample, determine a similarity score between the test embedding and a reference embedding by comparing each latent dimension of the test embedding and a corresponding latent dimension of the reference embedding; determine, in response to the similarity score exceeding a threshold score, that the provider and the user traveled together along at least a portion of a route of the service; and determine an amount of compensation to be provided from the user to the provider for the service using at least the portion of the route.

11 . The non-transitory computer readable storage medium of claim 10 , wherein the amount of compensation is determined using a distance traveled along the portion of the route.

12 . The non-transitory computer readable storage medium of claim 10 , wherein the amount of compensation is determined using a duration of travel time along the portion of the route.

13 . The non-transitory computer readable storage medium of claim 10 , having further instructions that when executed by the one or more processors cause the one or more processors to:
determine that the data sample indicates that the provider and the user did not travel together along a different portion of the route of the trip, wherein the amount of compensation does not account for the different portion of the route.

14 . The non-transitory computer readable storage medium of claim 10 , having further instructions that when executed by the one or more processors cause the one or more processors to:
determine that a safety incident occurred during the portion of the route.

15 . The non-transitory computer readable storage medium of claim 10 , wherein the portion of the data sample has a duration of time and a different data sample has a different duration of time, the reference embedding determined based at least in part on the different data sample.

16 . The non-transitory computer readable storage medium of claim 10 , wherein the test embedding and the reference embedding are generated using a model trained to infer latent variables based at least in part on feature vectors derived from data samples captured for services, the latent variables associated with the plurality of latent dimensions.

17 . The non-transitory computer readable storage medium of claim 10 , wherein the plurality of latent dimensions includes at least three dimensions.

18 . The non-transitory computer readable storage medium of claim 10 , wherein the similarity score is determined using cosine similarity between the test embedding and the reference embedding.

19 . A system comprising:
one or more processors; and a computer program product comprising a non-transitory computer readable storage medium having instructions, for verifying a service for a user and a provider, encoded thereon that, when executed by the one or more processors, cause the one or more processors to:
receive, from a client device, a data sample for a set of sensors of the client device, the data sample being associated with the service for the user and the provider;
generate a test embedding for the data sample, the test embedding using a plurality of latent dimensions that represent at least a portion of the data sample;
determine a similarity score between the test embedding and a reference embedding by comparing each latent dimension of the test embedding and a corresponding latent dimension of the reference embedding;
determine, in response to the similarity score exceeding a threshold score, that the provider and the user traveled together along at least a portion of a route of the service, and
determine an amount of compensation to be provided from the user to the provider for the service using at least the portion of the route.

20 . The system of claim 19 , wherein the non-transitory computer readable storage medium includes further instructions that when executed by the one or more processors cause the one or more processors to:
determine that the data sample indicates that the provider and the user did not travel together along a different portion of the route of the trip, wherein the amount of compensation does not account for the different portion of the route.
