    This study aims to investigate the identifiability of machine learning models such as latent dirichlet allocation (LDA) and neural network to improve the stability of their parameter estimations in consumer behavior analysis. The results of this study provide mainly two contributions. (1) LDA: The stability and identifiability of LDA in specific situations were clarified with simulation-based parameter recovery experiments. The author proposed Markov Chain Monte Carlo algorithms for the Bayesian estimation of constrained LDAs and showed their stability. (2) Neural network (autoencoder): The author proposed constrained estimation methods for neural networks and indicated that they provide stable and explainable results compared with an unconstrained standard neural network. However, these two main results were obtained under limited assumptions, so that the author will explore the extension and scope of the applications in the future study.
