Amazon patents system to flag weird data sent to AI models

Patent drawing
Patent drawing from the official filing.

Amazon describes a method for checking data before and after it goes through a machine learning model. The system converts the data into a mathematical format called an embedding and compares it against a list of known 'weird' or anomalous data points. If the new data looks too similar to the bad examples, the system can drop it, filter it, or send it to a different destination instead of letting it pass through.

Why it mattersThis helps ensure that AI systems don't get confused or broken by unexpected or malicious inputs, which is important for keeping automated services reliable.

In the filing’s own words

Systems and methods are provided to detect anomalous data obtained from and/or to be routed to a machine learning model. A system can receive a first set of data associated with a machine learning model (e.g., an output of and/or an input to the machine learning model). The system can generate an embedding of the first set of data and can compare the embedding with a second set of data based on the first set of data being associated with the machine learning model. The system can determine a manner of processing the first set of data based on comparing the second set of data and the embedding and can process the first set of data according to the manner of processing the first set of data.

What exactly they claim (claim 1)

1. A computing system comprising: data processing hardware; and memory in communication with the data processing hardware, the memory storing instructions, wherein execution of the instructions by the data processing hardware causes the data processing hardware to: obtain, from a user computing device, a first input, wherein the first input comprises a request to generate an output using a machine learning model; obtain, from a data store, a set of data based on obtaining the first input, wherein the set of data comprises one or more vector embeddings of anomalous data associated with the machine learning model; generate, using an embedding model, a first vector embedding of the first input; compare, using a vector search, the first vector embedding and the one or more vector embeddings; determine a manner of processing the first input based on comparing the first vector embedding and the one or more vector embeddings, wherein the manner of processing the first input indicates to drop the first input, route the first input to a first destination, or filter the first input; route the first input to the machine learning model based on the manner of processing the first input; obtain a first output of the machine learning model based on routing the first input to the machine learning model; generate, using the embedding model, a second vector embedding of the first output; compare, using the vector search, the second vector embedding and the one or more vector embeddings; determine a manner of processing the first output based on comparing the first vector embedding and the one or more vector embeddings, wherein the manner of processing the first output indicates to drop the first output, route the first output to a second destination, or filter the first output; and process the first output according to the manner of processing the first output.
