feedforward
Significado: A control system design in which the control action is determined by anticipating disturbances before they affect the output, rather than reacting to errors after they occur.
Feedforward contrasts with feedback: where feedback corrects errors after they happen, feedforward attempts to prevent them by measuring disturbances at the input and compensating in advance. In neural networks, a feedforward architecture passes data in one direction from input to output without loops. In management, 'feedforward' has been adopted as a term for future-focused coaching, offering suggestions for improvement rather than critiquing past performance.
Ejemplos
- The feedforward controller anticipated changes in demand and adjusted the valve position before any pressure deviation could occur. 前馈控制器预测需求变化,并在任何压力偏差发生之前调整阀门位置。El controlador feedforward anticipó los cambios en la demanda y ajustó la posición de la válvula antes de que se produjera cualquier desviación de presión.フィードフォワード制御器は需要の変化を予測し、圧力偏差が発生する前にバルブの位置を調整した。피드포워드 제어기는 수요 변화를 예측하고 압력 편차가 발생하기 전에 밸브 위치를 조정했다.
- A feedforward neural network with three hidden layers was trained to classify the medical imaging data. 一个具有三个隐藏层的前馈神经网络被训练用于对医学影像数据进行分类。Se entrenó una red neuronal feedforward con tres capas ocultas para clasificar los datos de imagen médica.3つの隠れ層を持つフィードフォワードニューラルネットワークが医用画像データの分類のために訓練された。3개의 은닉층을 가진 피드포워드 신경망이 의료 영상 데이터 분류를 위해 훈련되었다.
- The coaching model emphasised feedforward rather than feedback, encouraging staff to focus on what they could do differently next time. 该辅导模式强调前馈而非反馈,鼓励员工关注下次可以如何做得不同。El modelo de coaching hizo hincapié en el feedforward en lugar del feedback, animando al personal a centrarse en lo que podían hacer de forma diferente la próxima vez.そのコーチングモデルはフィードバックではなくフィードフォワードを重視し、次回どう変えられるかに焦点を当てるようスタッフに促した。그 코칭 모델은 피드백보다 피드포워드를 강조하며, 다음번에 무엇을 다르게 할 수 있는지에 초점을 맞추도록 직원들을 독려했다.
