The problem of document structure reconstruction refers to converting digital or scanned documents into corresponding semantic structures. Most existing works mainly focus on splitting the boundary of each element in a single document page, neglecting the reconstruction of semantic structure in multi-page documents. This paper introduces hierarchical reconstruction of document structures as a novel task suitable for NLP and CV fields. To better evaluate the system performance on the new task, we built a large-scale dataset named HRDoc, which consists of 2,500 multi-page documents with nearly 2 million semantic units. Every document in HRDoc (a) Multi-page documents (b) Line-level classification has line-level annotations including categories and relations obtained from rule-based extractors and human annotators. Moreover, we proposed an encoder-decoder-based hierarchical document structure parsing system (DSPS) to tackle this problem. By adopting a multi-modal bidirectional encoder and a structure-aware GRU decoder with soft-mask operation, the DSPS model surpass the baseline method by a large margin.

Panasonic's baby monitors have a pretty strong reputation, and after using the KX-HN4101W model, I have to say it's well-earned. This camera and parent unit kit comes with pan-and-tilt capability; smart motion, sound, and temperature detection and alerts; two-way communication; and a built-in sound library. In other words, offers everything the modern parent desires in a baby monitor. And it's dead simple to operate, so it won't saddle new parents with yet another learning curve to master. I don't know if it was intentional or not, but the camera resembles a cute, Wall-E style robot with a two-eyed, rectangular camera head on an egg-shaped body.

All of these plans include SmartZone motion detection, a feature that lets you set a custom area within each camera's field of view for motion-triggered video capture and notifications. A free trial is included with the camera, so you can try these features out and decide if you want to invest in them for the long term. The Lux65 is a great way to keep an eye on your baby or small child, but $184 for what is basically a conventional video baby monitor without a Hubble Connected subscription is a little steep. Considering you need one of those subscriptions to unlock all the Lux65 has to offer, you're looking at an initial outlay of more than $200, plus the recurring annual subscription cost. If that's beyond your budget, something like the VTech VM3251 Expandable Digital Video Baby Monitor will give you most of the same basic features without the Wi-Fi capability for less than $100.
