The latest knowledge distillation (KD) methods have successfully supervised a student model to have a better representation using intermediate layers of a teacher model. However, the previous KD methods did not obtain generalized knowledge for various object scales from a one-stage object detector because the one-stage object detector has a structural property that uses several intermediate layers to extract objects of various scales. In other words, the previous KD methods could not distill and transfer knowledge to intermediate layers of one-stage object detectors in a balanced way. Therefore, we propose a shared knowledge encoder and an averaged prototype transfer to remove or mitigate the distillation and transfer imbalances that adversely affect the KD process. Experimental results show that the proposed KD method outperforms the state-of-the-art methods. For instance, the proposed method provides about 1.3% and 2.2% higher accuracy than the baseline on the PASCAL VOC and MS COCO datasets, respectively.

Emerging wireless ad-hoc networks find their most important applications in untethered, mobile, multihop scenarios where there is no wired infrastructure. Yet, when the wired infrastructure (say, the Internet) is within reach, opportunistic connections to Internet sites may be established across the multihop network to transfer files and update databases. These file transfers use TCP for reliability and congestion control. Many believe that TCP should not be used in ad-hoc network due to it's inability to adapt to the high loss environment, but we believe that TCP will always have a part to play in wireless network in one form or another; studying the behavior of TCP will provide the direction for that adaptation. Recent experiments with ad-hoc, multihop 802.11 networks have exposed serious instabilities when TCP connections span both wired and wireless domains. In particular, some TCP connections capture the wireless channel and drive the throughput on other connections virtually to zero. This is most surprising in view of the fact that connections between 802.11 (single hop) wireless LAN stations and the Internet are well behaved, stable and fair. The problem of the unfairness compounds further when TCP connections have to share the bandwidth with in multihop ad-hoc network. In this paper, we present the issues regarding the wireless transport protocols by experimentally analyzing TCP performance.
