Incrementally update the dataset used for an examples model.

## Path parameters

- `projectsId` string, required
- `locationsId` string, required
- `modelsId` string, required

## Request body

- GoogleCloudAiplatformV1UpdateExplanationDatasetRequest: Request message for ModelService.UpdateExplanationDataset.
  - `examples` GoogleCloudAiplatformV1Examples: Example-based explainability that returns the nearest neighbors from the provided dataset.
    - `exampleGcsSource` GoogleCloudAiplatformV1ExamplesExampleGcsSource: The Cloud Storage input instances.
      - `dataFormat` 'DATA_FORMAT_UNSPECIFIED' | 'JSONL': The format in which instances are given, if not specified, assume it's JSONL format. Currently only JSONL format is supported.
      - `gcsSource` GoogleCloudAiplatformV1GcsSource: The Google Cloud Storage location for the input content.
        - `uris` string[]: Required. Google Cloud Storage URI(-s) to the input file(s). May contain wildcards. For more information on wildcards, see https://cloud.google.com/storage/docs/wildcards.
    - `nearestNeighborSearchConfig` unknown
    - `neighborCount` integer: The number of neighbors to return when querying for examples.
    - `presets` GoogleCloudAiplatformV1Presets: Preset configuration for example-based explanations
      - `modality` 'MODALITY_UNSPECIFIED' | 'IMAGE' | 'TEXT' | 'TABULAR': The modality of the uploaded model, which automatically configures the distance measurement and feature normalization for the underlying example index and queries. If your model does not precisely fit one of these types, it is okay to choose the closest type.
      - `query` 'PRECISE' | 'FAST': Preset option controlling parameters for speed-precision trade-off when querying for examples. If omitted, defaults to `PRECISE`.

## Response `200`

Successful response

- GoogleLongrunningOperation: This resource represents a long-running operation that is the result of a network API call.
  - `done` boolean: If the value is `false`, it means the operation is still in progress. If `true`, the operation is completed, and either `error` or `response` is available.
  - `error` GoogleRpcStatus: The `Status` type defines a logical error model that is suitable for different programming environments, including REST APIs and RPC APIs. It is used by [gRPC](https://github.com/grpc). Each `Status` message contains three pieces of data: error code, error message, and error details. You can find out more about this error model and how to work with it in the [API Design Guide](https://cloud.google.com/apis/design/errors).
    - `code` integer: The status code, which should be an enum value of google.rpc.Code.
    - `details` object[]: A list of messages that carry the error details. There is a common set of message types for APIs to use.
    - `message` string: A developer-facing error message, which should be in English. Any user-facing error message should be localized and sent in the google.rpc.Status.details field, or localized by the client.
  - `metadata` object: Service-specific metadata associated with the operation. It typically contains progress information and common metadata such as create time. Some services might not provide such metadata. Any method that returns a long-running operation should document the metadata type, if any.
  - `name` string: The server-assigned name, which is only unique within the same service that originally returns it. If you use the default HTTP mapping, the `name` should be a resource name ending with `operations/{unique_id}`.
  - `response` object: The normal, successful response of the operation. If the original method returns no data on success, such as `Delete`, the response is `google.protobuf.Empty`. If the original method is standard `Get`/`Create`/`Update`, the response should be the resource. For other methods, the response should have the type `XxxResponse`, where `Xxx` is the original method name. For example, if the original method name is `TakeSnapshot()`, the inferred response type is `TakeSnapshotResponse`.
