We're blogging Federal learning: dividing non IID samples by ill conditioned independent identically distributed We have studied the division of samples according to pathological non IID in the paper of the founding of federal learning [1]. In the last blog post Federal learning: dividing non IID samples by Dirichlet distribution We have also m ...

1, Brief introduction of BP neural network traffic sign recognition Road traffic signs are used to prohibit, warn, instruct and restrict road users to use roads in an orderly manner to ensure travel safety If the road traffic signs can be recognized automatically, the occurrence of road traffic accidents will be greatly reduced However, due to ...

This paper introduces the multitasking learning algorithm published by Ali in 2019. The model shows the Bayesian network causality between targets, integrates and models the complex causality network between features and multiple targets, and eliminates the strong independent assumptions in the general MTL model. Since there is no specific assu ...

[source code analysis] NVIDIA HugeCTR, GPU version parameter server -- (9) -- local hash table 0x00 summary In this series, we introduce HugeCTR, an industry-oriented recommendation system training framework, which is optimized for large-scale CTR models with model parallel embedding and data parallel intensive networks. This article introduce ...

Figure ImageNet of neural network? Open source millions of OGB benchmark data sets such as Stanford University In the small data full of "MNIST", does graph neural network also need a big benchmark such as "ImageNet"? Recently, Professor Jure Leskovec of Stanford University announced the open source of Open Graph Benchmar ...

& & other algorithms 1, Algorithm Given an array of prices, its ith element price [i] represents the price of a given stock on day I. You can only choose to buy this stock one day and sell it on a different day in the future. Design an algorithm to calculate the maximum profit you can make. Return the maximum profit you can make ...

@Created on: 20210413 @Modified on: 20210413 1. Background At keras In the Sequential sequential model API of layers, the Sequential model is a linear stack of multiple network layers. You can pass the list of layers to the Sequential constructor. The methods and properties include: model.layers is a flattened list that contains the netw ...

Creating a bitcoin trading robot will not lose money In this article, we will create a deep reinforcement learning agent to learn to make money through bitcoin trading. In this tutorial, we will use the PPO agent in OpenAIgym and the stable baselines Library (a branch of OpenAI's baselines Library). The purpose of this series of articles is to ...
