Minimalist notes detnet:a backbone network for Object detection The core of this paper presents a backbone network:detnet specially used for detection task. At present, the main method of Detection network is based on classification network plus FPN and RPN structure. Most of the classification networks increase pixel sensitivity by reducing the spatial size of the deep layer, and the smaller resolution has a certain degree of influence on the accuracy of the positioning of large objects. In th

, eliminating the need to read and write HDFs. As a result, Spark is better suited to algorithms that require iterative MapReduce such as data mining and machine learning . About the principle of spark application, and so on, there is not much to say, another day I write a separate to chat. Now you just have to know that it can get your program distributed and run.Elephas (Deep Learning Library with spark support)First say Keras, it is b

Preface This article will be the latest and most complete evaluation of a depth learning framework since the second half of 2017. The evaluation here is not a simple use evaluation, we will use these five frameworks to complete a depth learning task, from the framework of ease of use, training speed, data preprocessing of the complexity, as well as the size of the video memory footprint to carry out a full range of evaluation, in addition, we will also give a very objective, Very comprehensive

learning libraries at this stage, as these are done in step 3. Step 2: Try Now that you have enough preparatory knowledge, you can learn more about deep learning. Depending on your preferences, you can focus on: Blog: (Resource 1: "Basics of deep Learning" Resource 2: "Hacker's Neural Network Guide") Video: "Simplified deep learning" Textbooks: Neural networks and deep learning In addition to these prerequisites, you should also know the popular deep learning library and the languages that run

TensorFlow version 1.4 is now publicly available-this is a big update. We are very pleased to announce some exciting new features here and hope you enjoy it. Keras In version 1.4, Keras has migrated from Tf.contrib.keras to the core package Tf.keras. Keras is a very popular machine learning framework that contains a number of advanced APIs that can minimize the

Installation EnvironmentWin7+anconda (I have two versions of 2 and 3)2. A great God said to open cmd directly, enter PIP install Keras, and then automatically installed.

its API is difficult to use. (Project address: Https://github.com/shogun-toolbox/shogun)2, KerasKeras is a high-level neural network API that provides a Python deep learning library. For any beginner, this is the best choice for machine learning because it provides a simpler way to express neural networks than other libraries. The Keras is written in pure Python and is based on the TensorFlow, Theano, and cntk back end.According to the official websi

, which are a great plus when it comes To comparing it and other similar libraries.The biggest complaint out there is and the API may are unwieldy for some, making the library hard to use for beginners. However, there is wrappers that ease the pain and make working with Theano simple, such as Keras, Blocks and lasagne.Interested in learning about Theano?

So if your data science team is it -centric, it might not be your best choice, and we'll talk about simpler alternatives. 1.3 use Caseconsidering the TensorFlow 's complexity, its use cases mainly include solutions for large companies that have experts in the field of machine learning. For example, the UK online supermarket Ocado uses TensorFlow to prioritize their contact centres and improve demand forecasts. At the same time, AXA, the glo

Implement the LSTM model in Python There are a number of packages in Python that can be called directly to build lstm models, such as Pybrain, Kears, TensorFlow, cikit-neuralnetwork, etc. (more stamp here ). Here we choose keras.
