vector
意味: A quantity that has both magnitude and direction, often represented as an arrow or an ordered list of numbers. In biology, an organism that transmits a pathogen from one host to another.
Vectors are essential in physics and engineering for representing forces, velocities, and displacements. In computing, a vector can refer to a one-dimensional array of data. In epidemiology, mosquitoes are a common vector for diseases like malaria. The term is distinguished from 'scalar,' which has magnitude only. It collocates with 'force,' 'velocity,' 'position,' 'unit,' and 'disease.'
例文
- The velocity vector indicates both the speed and direction of the moving object. 速度向量表示运动物体的速率和方向。El vector velocidad indica tanto la rapidez como la dirección del objeto en movimiento.速度ベクトルは移動する物体の速さと方向の両方を示します。속도 벡터는 운동하는 물체의 속력과 방향을 모두 나타냅니다.
- Mosquitoes serve as the primary vector for the transmission of dengue fever. 蚊子是登革热传播的主要媒介。Los mosquitos son el principal vector de transmisión del dengue.蚊はデング熱の伝播における主要な媒介生物として知られています。모기는 뎅기열 전파의 주요 매개체입니다.
- In machine learning, each data point is represented as a feature vector in a high-dimensional space. 在机器学习中,每个数据点被表示为高维空间中的特征向量。En aprendizaje automático, cada punto de datos se representa como un vector de características en un espacio de alta dimensión.機械学習では、各データポイントは高次元空間における特徴ベクトルとして表現されます。기계학습에서 각 데이터 포인트는 고차원 공간의 특징 벡터로 표현됩니다.
