Accurate HIV incidence estimation based on individual recent infection status (recent vs long-term infection) is important for monitoring the epidemic, targeting interventions to those at greatest ris...
基于Co-training的用户属性预测研究
用户属性 Co-training 稀疏自编码器 梯度下降算法
2018/7/4
针对当前基于第三方应用数据的用户属性预测算法较少考虑应用前台实际使用时长问题，提出了“手机应用前台均使用时长”特征，同时采用基于稀疏自编码器和神经网络的Co-training框架，充分利用大量未标注数据，从应用类别和前台均使用时长两个角度进行属性预测。实验进行时，首先使用未标注数据对网络进行初始化，然后采用基于准确率的梯度下降算法对参数进行更新。实验结果表明，本文算法提高了用户属性预测准确率。
Generalization of Extended Baum-Welch Parameter Estimation for Discriminative Training and Decoding

We demonstrate the generalizability of the Extended Baum-Welch (EBW) algorithm not only for HMM parameter estimation but for decoding as well. We show that there can exist a general function associate...
