| contents | This study addresses the issue of leveraging federated learning to improve data privacy and performance in IVF embryo selection. The EM (Expectation-Maximization) algorithm is incorporated into deep learning models to form a federated learning framework for quality evaluation of blastomere cleavage using two-dimensional images. The framework comprises a server site and several client sites characterized in that each is locally trained with an EM algorithm. Upon the completion of the local EM training, a separate 5-mode mixture distribution is generated for each client, the clients' distribution statics are then uploaded to the server site and aggregated therein to produce a global (sharing) 5-mode distribution. During the inference phase, each client uses image classifiers and an instance segmentor, assisted by the global 5-mode distribution acting as a calibrator to (1) identify the absolute cleavage timing of blastomere, i.e., tPNa, tPNf, t2, t3, t4, t5, t6, t7, and t8, (2) track the cleavage process of blastomeres to detect the irregular cleavage patterns, and (3) assess the symmetry degree of blastomeres. Experimental results show that the proposed method outperforms commercial Time-Lapse Incubators in reducing the average error of timing prediction by twofold. The proposed facilitate frameworks the adaptability and scalability of classifiers and segmentor to data variability associated with patients in different locations or countries. |
