java 框架可以通过以下三种方式集成 ai 技术:通过 api 访问、使用 java 采用开放标准的客户端库。api 访问可以轻松使用 ai 各种供应商提供 ai 服务。java 允许客户端库直接与 ai 集成过程简化了服务交互。开放标准如 protocol buffers 或 grpc 与提供商无关的可实现 ai 集成。
Java 框架与人工智能 (AI) 的集成方法
随着 AI 将在企业中普及 AI 技术集成到 Java 应用程序变得越来越重要。以下是常见的方法:
1. 通过 API 访问
立即学习“Java免费学习笔记(深入);
使用 AI 提供商提供的 API,如 Google Cloud AI Platform 或 AWS SageMaker,它可以很容易地访问各种各样的东西 AI 服务包括机器学习、自然语言处理和计算机视觉。
import com.google.cloud.aiplatform.v1.EndpointServiceClient; import com.google.cloud.aiplatform.v1.EndpointServiceSettings; import com.google.cloud.aiplatform.v1.PredictRequest; import com.google.cloud.aiplatform.v1.PredictResponse; import java.io.IOException; public class AiApiExample { public static void main(String[] args) throws IOException { // Set the endpoint URI String endpoint = "YOUR_ENDPOINT_URI"; // Initialize the client EndpointServiceSettings settings = EndpointServiceSettings.newBuilder().build(); EndpointServiceClient client = EndpointServiceClient.create(settings); // Prepare the prediction request PredictRequest.Builder requestBuilder = PredictRequest.newBuilder(); requestBuilder.setEndpoint(endpoint); // Add the input data here PredictRequest request = requestBuilder.build(); // Perform the prediction PredictResponse response = client.predict(request); // Process the prediction response // ... } }
2. 使用 Java 客户端库
一些 AI 提供商提供 Java 允许客户端库直接与客户端库连接 AI 服务互动,从而简化了集成。
import com.google.cloud.automl.v1beta1.ImageClassificationPredictResponse; import com.google.cloud.automl.v1beta1.PredictRequest; import com.google.cloud.automl.v1beta1.PredictRequest.ParamsEntry; import com.google.cloud.automl.v1beta1.PredictResponse; import com.google.cloud.automl.v1beta1.PredictionServiceClient; import com.google.cloud.automl.v1beta1.PredictionServiceSettings; import java.io.IOException; import java.nio.file.Paths; public class AiClientLibExample { public static void main(String[] args) throws IOException { // Set the endpoint URI String endpoint = "YOUR_ENDPOINT_URI"; // Set the prediction input String filePath = "YOUR_IMAGE_FILE_PATH"; // Initialize the client PredictionServiceSettings settings = PredictionServiceSettings.newBuilder().build(); PredictionServiceClient client = PredictionServiceClient.create(settings); // Prepare the prediction request PredictRequest.Builder requestBuilder = PredictRequest.newBuilder(); requestBuilder.setEndpoint(endpoint); requestBuilder.putParams( "score_threshold", ParamsEntry.newBuilder().setDoubleValue(0.5).build()); requestBuilder.addImage(Paths.get(filePath)); PredictRequest request = requestBuilder.build(); // Perform the prediction PredictResponse response = client.predict(request); // Process the prediction response for (ImageClassificationPredictResponse prediction : response.getPayloadList().expandList().getImageClassification()) { // Process the prediction result // ... } } }
3. 使用开放标准
如 Protocol Buffers 或 gRPC,可用于与 AI 服务通信。这样,与提供商无关的可以实现 AI 集成。
import com.google.protobuf.ByteString; import io.grpc.ManagedChannel; import io.grpc.ManagedChannelBuilder; import io.grpc.StatusRuntimeException; import org.tensorflow.framework.TensorShapeProto; import org.tensorflow.framework.TensorProto; import org.tensorflow.serving.apis.Model; import org.tensorflow.serving.apis.PredictRequest; import org.tensorflow.serving.apis.PredictResponse; import org.tensorflow.serving.apis.PredictionServiceGrpc; public class AiOpenStandardExample { public static void main(String[] args) throws Exception { // Set the server address String serverAddress = "YOUR_SERVER_ADDRESS"; // Connect to the server ManagedChannel channel = ManagedChannelBuilder.forTarget(serverAddress).usePlaintext().build(); PredictionServiceGrpc.PredictionServiceBlockingStub stub = PredictionServiceGrpc.newBlockingStub(channel); // Prepare the prediction request TensorProto input = TensorProto.newBuilder() .addDtype(TensorProto.DataType.DT_FLOAT) .addShape(TensorShapeProto.getDefaultInstance()) .addFloatVal(1.0f) .addFloatVal(2.0f) .build(); PredictRequest request = PredictRequest.newBuilder() .setModel(Model.newBuilder().setName("YOUR_MODEL_NAME").build()) .putInputs("input1", input) .build(); // Perform the prediction try { PredictResponse response = stub.predict(request); // Process the prediction response TensorProto output = response.getOutputsMap().get("output1"); float prediction = output.getFloatVal(0); // ... } catch (StatusRuntimeException e) { // Handle error e.printStackTrace(); } } }
