Step by step to understand the python Chatbot tutorial code - define the model

Readme I'm a programming Xiaobai. Although the registration time is long, I'm not engaged in coding. I began to teach myself Python in order to learn AI. I usually knock the code according to the book, but I don't have a deep understanding. Now I want to study chatbot and find that my coding level needs to be strengthened, so I open this s ...

Pytoch-4.1 fine tuning model

4.1 Fine tuning model 4.1.1 what is fine tuning What if you don't have much training data for a task? We first find a similar model trained by others, take the ready-made trained model of others, replace it with our own data, adjust the parameters, and train again. This is fine tune. Why fine tune For the case that the data set itself is ve ...

Deep learning notes (based on pytorch) - Numpy Foundation

Array deformation reshape Definition: change the vector arr dimension again without modifying the vector itself. That is, it does not affect the content under the original address, creates a copy result and outputs it. import numpy as np arr = np.arange(10) print(arr) # Transform the vector arrr dimension into 2 rows and 5 columns print ...

DenseNet Paper Details and PyTorch Replication

DenseNet 1. ResNet and DenseNet ResNet (Deep Residual Network): By establishing a "short-circuit connection" between the front and back layers, this helps to reverse the propagation of gradients during training, resulting in a deeper CNN network. DenseNet: uses a dense join mechanism, where all layers are connected to each other, a ...

FPN of Backbone: feature pyramid (pytoch implementation and code analysis)

  Background:          In order to enhance semantics, the traditional object detection model usually only carries out subsequent operations on the last feature map of the deep convolution network, and the down sampling rate (multiple of image reduction) corresponding to this layer is usually large, ...

Data set processing - tiny Imagenet

1, Introduction    recently, in addition to some experiments on large-scale data sets (ImageNet-1k and ImageNet-21k), we also did some ablation studies on small data sets. Among them, pytorch has its own cifar10 and cifar100 data loading, while Tiny ImageNet does not. So simply record the processing of this data set here.   ...

Why do neural networks think your cat is a cat: Magical class activation map CAM Technology (with pytoch implementation code)

1 Introduction For the general classification, we import the data into the neural network, which tells us what kind it is. For some necessary cases, we need to know how the neural network makes judgment, and which parameters of the input data affect the judgment of the neural network. Therefore, the paper Learning Deep Features for Discriminat ...
