在计算机科学中,biasing 指通过调整参数或数据来引入系统性偏差,常用于机器学习或统计模型以优化性能或处理不平衡数据。

用法要点

句型搭配

Biasing 通常作为动名词或名词使用,常见于被动语态或与介词搭配,如用于描述模型训练或数据处理中的偏差引入过程。

• biasing the model
• biasing towards a class
• biasing against outliers

介词用法

常与介词 towards、against、for 连用,表示偏差的方向或目标,例如 biasing towards positive samples 表示偏向正样本。

• biasing towards the majority
• biasing against noise
• biasing for accuracy

语域说明

Biasing 主要出现在学术、技术或专业语境中,特别是计算机科学、数据分析和机器学习领域,日常对话中较少使用。

• biasing in neural networks
• biasing for fairness
• biasing in statistical analysis

基础例句

In this project, we are biasing the data to improve the model's accuracy on rare cases.

在这个项目中,我们正在对数据进行偏置处理,以提高模型在罕见情况下的准确性。

常见错误

❌ 错误:We need to bias the data for better results.
✓ 正确:We need to apply biasing to the data for better results.

错误用法中直接使用 'bias' 作为动词可能不准确,因为 'biasing' 更常作为动名词或名词,表示偏置过程;正确用法强调应用偏置操作。

❌ 错误:The biasing is too strong, it causes overfitting.
✓ 正确:The biasing is too strong, causing overfitting.

错误用法中使用了 'it causes' 导致句子结构冗余;正确用法使用现在分词 'causing' 使句子更简洁流畅,符合英语表达习惯。

近义词辨析

skewing

Skewing 更强调数据分布的不对称或倾斜,常用于描述统计偏差;而 biasing 更侧重于人为或系统性引入偏差以达成特定目标,如优化模型。

Skewing the data may distort the analysis, whereas biasing it can be intentional for model tuning.

weighting

Weighting 指分配权重以调整重要性,常用于加权平均或采样;biasing 则更广泛地涉及引入偏差,可能包括权重调整但不限于此,如数据预处理中的偏置。

Weighting the samples gives more importance to certain data points, while biasing might involve altering the entire dataset distribution.
