Limitations and Future Aspects of Communication Costs in Federated Learning: A Survey.

This paper explores the potential for communication-efficient federated learning (FL) in modern distributed systems. FL is an emerging distributed machine learning technique that allows for the distributed training of a single machine learning model across multiple geographically distributed clients. This paper surveys the various approaches to communication-efficient FL, including model updates, compression techniques, resource management for the edge and cloud, and client selection. We also review the various optimization techniques associated with communication-efficient FL, such as compression schemes and structured updates. Finally, we highlight the current research challenges and discuss the potential future directions for communication-efficient FL.

Induction of labor: a comparative study of intravaginal misoprostol and dinoprostone.

OBJECTIVE: To compare the efficacy and safety of intravaginal misoprostol and dinoprostone for elective induction of labor in nulliparous women with an unfavorable cervix. MATERIALS AND METHODS: A quasi-experimental study was conducted in Bahawal Victoria Hospital, Bahawalpur, Pakistan, from July 1, 2005 to August 31, 2006. A total of 120 primigravid women with gestational ages of > 40 weeks to < 42 weeks were divided into two groups. Group A (n = 60) was given 50 microg of misoprostol and Group B (n = 60) was given 3 mg of dinoprostone every 6 hours, for a maximum of three doses. RESULTS: The induction to onset of significant uterine contractions and delivery intervals were lower in Group A than in Group B (6.1 vs. 7.2 hours; p = 0.16; and 8.2 vs. 11.0 hours; p = 0.007, respectively). Group A had a lower cesarean section rate than Group B (7% vs. 30%; p = 0.003), but a higher rate of uterine hyperstimulation (10% vs. 3%; p = 0.16), tachysystole (17% vs. 3%; p = 0.02), and neonatal admissions to the intensive care unit within 24 hours of delivery (4 vs. 3; p = 0.71) and after 24 hours (2 vs. 1; p = 0.56) than Group B. CONCLUSION: Vaginal misoprostol is more effective than dinoprostone for the elective induction of labor beyond 40 weeks of gestation, but is associated with more uterine hyperstimulation, tachysystole, and neonatal intensive care unit admissions.
