PHP 函数并发编程在人工智能中的应用

use ReactPromiseDeferred;// 创建神经网络模型$model = new NeuralNetwork();// 创建一个函数来训练模型$trainFunction = function (array $data) {    $model->train($data);};// 创建协程池$coroutinePool = new ReactEventLoopStreamSelectLoop();// 创建一个池中的协程列表$coroutines = [];// 遍历数据，为每个数据点创建协程foreach ($data as $key => $dataPoint) {    $deferred = new Deferred();    $coroutine = $coroutinePool->coroutine($trainFunction, [$dataPoint]);    $coroutine->then(function () use ($key) {        // 训练完成后，从结果中收集权重        $weights[$key] = $model->getWeights();    });    $coroutines[] = $coroutine;}// 并发执行协程$coroutinePool->run();// 收集所有权重并更新模型foreach ($weights as $key => $weight) {    $model->setWeights($key, $weight);}
