符号回归在精准畜牧业中的应用探索：基于母猪加速度传感器数据预测分娩时间
Exploring the Potential of Symbolic Regression in Precision Livestock Farming
AI 导读
一项研究利用母猪加速度传感器数据，用符号回归预测分娩剩余时间，平均绝对误差为 9.28 小时，性能与可解释性均优于支持向量回归和人工神经网络等闭箱模型。研究先在 180 头母猪中的 166 头检测到筑巢行为，其中 149 头在分娩前 48 小时内成功检出，该检测仅基于活动水平变化、未使用机器学习。

Abstract:The ability to predict farrowing time in pigs is crucial for optimal farm management and ensuring piglet survival. This study investigates the potential of explainable artificial intelligence for precision livestock farming, focusing on acceleration sensor data from sows around the time of farrowing. Accurately predicting farrowing allows farmers to balance both, piglet safety by avoiding piglet crushing events and the mother sow's welfare, by avoiding early crating. Traditional machine learning models often lack interpretability (``closed-box'' problem). Explainable artificial intelligence offers a solution by revealing the decision-making processes within the models. This work is split into two stages. First the detection of nest building behaviour and second the prediction of the remaining time to farrowing. The nest building detection was possible for 166 out of 180 sows and successful within 48 hours before farrowing for 149 sows. The nest building detection is purely based on the change of a sow's activity level and uses no machine learning techniques. Further, this study utilizes symbolic regression, an open-box modelling technique that generates interpretable mathematical formulas, to predict the remaining time until the onset of farrowing. The results are compared with closed-box models, like support vector regression and artificial neural networks, for both explainability and performance. Notably, symbolic regression achieved a mean absolute error of 9.28 hours for the time-to-farrowing prediction, outperforming the closed-box models in terms of performance and interpretability. This research demonstrates that explainable artificial intelligence, specifically symbolic regression, can offer both interpretable results and competitive performance in precision livestock farming.
