摘要:

失业动态的数学模型试图预测求职者找到工作的概率作为时间的函数。这通常是通过使用失业记录中的信息来实现的。这些记录是右删失的,使得生存分析成为参数估计的合适方法。该模型使用深度人工神经网络(ANN)作为非线性风险函数。通过嵌入,高基数的分类特征被有效地分析。神经网络参数的后验分布估计使用变分贝叶斯方法。该模型是根据斯洛文尼亚公共就业服务局提供的2011年至2020年的就业时间数据集进行评估的。它用于确定记录中每个人在一段时间内的就业概率。类似的模型可以应用于其他问题的多维,高基数的分类数据,包括删失记录。这些数据经常出现在个人记录中,例如医疗记录。

英文摘要:

Mathematical modelling of unemployment dynamics attempts to predict the probability of a job seeker finding a job as a function of time. This is typically achieved by using information in unemployment records. These records are right censored, making survival analysis a suitable approach for parameter estimation. The proposed model uses a deep artificial neural network (ANN) as a non-linear hazard function. Through embedding, high-cardinality categorical features are analysed efficiently. The posterior distribution of the ANN parameters are estimated using a variational Bayes method. The model is evaluated on a time-to-employment data set spanning from 2011 to 2020 provided by the Slovenian public employment service. It is used to determine the employment probability over time for each individual on the record. Similar models could be applied to other questions with multi-dimensional, high-cardinality categorical data including censored records. Such data is often encountered in personal records, for example in medical records.
