derivatives) that consists of the slope of each dimension. The derivation formula for one-dimensional function is as follows:When a function has more than one parameter, we call the derivative a partial derivative. The gradient is the vector formed by the partial derivative on each dimension.Most optimized notes (top) finish.Translator Feedback

When learning the windowmanager interface, I learned that this interface is very important because it can directly interact with the window manager. What exactly is this window manager?
By searching for information, I know that window manager is actually a service ). It is globally unique in the system and is independent from Android applications. All Android applications share a separate C ++ service. (For this "separate C ++ service", we recommend t
advantage of multi-core CPU resources, data recovery is faster than AOF, but the Rdb method is easy to lose data, some companies in order to make full use of CPU resources, the REDIS process and CPU core binding, When an RDB is made, the child process and the parent process are resource-competitive and affect service throughput.AOF more secure, can be more timely synchronization of data to the file, but aof need more disk IO expenditure, aof file siz
Keras is a python library for deep learning that contains efficient numerical libraries Theano and TensorFlow.
The purpose of this article is to learn how to load data from CSV and make it available for keras use, how to model the data of multi-class classification using neural network, and how to use Scikit-learn to evaluate Keras neural network models.Preface,
task, and overlapping red circles represent shared feature areas, which are used to capture common features that exist between different tasks.This article uses confrontation training to ensure that the shared space contains only multi-tasking shared information, as well as the use of orthogonal constraints to eliminate redundant information between shared and private spaces.

Multi-Thread Programming Based on Qt Learning
QT provides support for threads in three forms. They are,
I. platform-independent threadsIi. Thread-safe event delivery3. Cross-thread signal-slot connection.
This makes it easier to develop lightweight multi-threaded Qt programs and make full use of the advantages of multi
data.Like what:void QPen::setStyle(Qt::PenStyle style){ detach(); detach from common data d->style = style; // set the style member}void QPen::detach(){ if1) { ... // perform a deep copy }}It is generally felt that implicit sharing and multithreading are not very harmonious due to the existence of a reference count. One of the ways to protect a reference count is to use a mutex, but it is very slow. The
Minimalist notes multi-task self-supervised Visual Learning
Paper Address: https://arxiv.org/abs/1708.07860
The core of this paper is to pretrain the model with the task of self supervision, then to migrate the resulting model to the related task for finetuning (this is to compare the skeleton network parameters without updating the head of different tasks), The desired performance is close to the Pretrai

Set, List, Map, and setmap in Multi-learning JavaFor a long time, the List of data that has been used in the Code is mainly List, and it is all ArrayList. This is enough. ArrayList is a packaging tool class used to implement dynamic arrays, so that code can be pulled in and pulled out during code writing, and iterative traversal is quite convenient. I also don't know when the tool classes such as HashMap an
