http://www.dengfanxin.cn/?p=403Original address I have translated the main parts of an important work on object detection, sppnet, in the paper. Sppnet's original intention is very clear, is that the network to the size of the input is more flexible, analysis to the convolutional network size is not required, the requirements of the fixed size is entirely from the whole connection layer, so the use of spatial pyramid pooling method to connect

Original Spatial adjustment can be used to correct the location of a factor so that it can match the data in the database more accurately; it can also match the units of data obtained from a digital device or scanner to the units in the real world. It can also match low-precision data to high-precision data. Space correction tools include space transform, rubbersheet, edge match, and attribute transfer. Each tool has one option. This document takes th

"Editor's note" as an open source object-relational database, Postgres has been loved by many developers. Recently, Postgres officially released version 9.5, which has been a lot of repair and functional improvements. This article will share 10 Postgres usage tips, which are designed to enable developers to use the database more flexibly and efficiently.During th

pooling of spatial pyramids Overview of the spatial pyramid pooling layer: in the convolution operation of the picture, the size of the convolution core is not changed, the weight of the inverse adjustment is only the value will change. But, however, the size of the input picture can you control it. Haha, the size of our input images will change, where the change in image size does not affect the convolut

provided by using the revolutionary serializable snapshot Isolation (SSI) level. Today we start with the basics of PostgreSQL and talk about the features of MVCC and PostgreSQL. Here, we first use a table to show the level of transaction in PostgreSQL, and we can turn it back when we see the later chapters. 1. Basic Knowledge 1.1 Transaction ID When a transaction begins, the transaction management system in PostgreSQL assigns a unique identifier, the transaction ID (TXID), to the t

Q. What does XL stand? XL is short for extensible lattice. It also connotes an extra large version of postgresql, in this case when SS multiple systems. Q. Is this a "nosql" solution? No, ipvs-XL supports traditional SQL, stronugly conforms to ansi SQL: 2008, is fully acid, all while being scalable. you can however certainly use it as a key-value store and take advantage of JSON and hstore functionality.
