[beginners learn PyTorch tutorial] I. Basic operation of PyTorch

@Author: Runsen What is PyTorch? This is a Python based scientific computing package for two groups of audiences: NumPy is an alternative to take advantage of the power of GPU. Provide a deep learning research platform with maximum flexibility and speed. tensor Tensors are similar to NumPy's n-dimensional array. In addition, tensors ca ...

"Mini tutorial" how to use the time distribution layer correctly under LSTM network

The time distributed layer is a sequence rather than a single value that needs to be returned by the LSTM layer in the Keras interface. What is the time distributed layer The added complexity is the TimeDistributed layer (and the previous TimeDistributedDense layer), which is mysteriously described as a layer wrapper that allows us to app ...

ubuntu 18.04 reproducing OpenPCDet training evaluation visual loss function from scratch

ubuntu 18.04 reproducing OpenPCDet preface: I've installed NVIDIA 460 91.03 driver, and cuda 10.1 is also installed. However, because spconv (giant pit Library) needs to be installed in OpenPCDet, cuda above 10.2 can only pip install spconv of version 2.0, otherwise the old version of spconv is too difficult to install (countless pits). There ...

Transformation of dimensions

view and reshape operations The functions and usage of the two are the same, but it is necessary to ensure that the overall size of the view remains unchanged, that is, numel () is consistent view operation will lose dimension information. Remember the storage order of data a = torch.rand(4,1,28,28) b = a.view(4,28*28) #Two dimens ...

[RL] Q learning algorithm based on neural network (deep learning) (DQN)

DQN introduction DQN(Deep Q-Learning)It is the combination of deep learning and reinforcement learning Q-table He is too big to build words to use DQN Is a good choice. DQN algorithm mainly uses experience replay (experience pool) to realize the convergence of value function. The Deep Q-learning method is used to iteratively update Q (s, ...

Pre trained word embedding is used in Keras model

The original address is here. What is word embedding? Word embedding is a series of natural language processing technologies aimed at mapping semantics to geometric space. This is done by associating a number vector with each word in the dictionary, so that the distance between any two vectors (such as L2 distance or more commonly cosine d ...

Notes on understanding TensorFlow - Chapter 3.2 data carrier: tensor

In order to define the mathematical expression more conveniently and describe the mathematical model more accurately, TF uses Tensor to represent all data uniformly. In the actual calculation formula, that is, the transformation process of the expression, the data in the expression corresponding to the model is carried by the Tensor. Provide ...
