Machine learning

TabNine: Code completion tool based on OpenAI language model. Support for 23 programming languages, 5 editors (VS Code, Sublime Text, Atom, Emacs, Vim), easy to use, amazing results

Hub: an aggregation center of classical models in computer vision and natural language processing. There are plenty of hubs these days — GitHub, SciHub, xxxxHub, etc. — but the pyTorch-Hub was recently promoted by Turing award winner Yann LeCun. Whether it is ResNet, BERT, GPT, VGG, PGAN or MobileNet classic models, just enter a line of code, can achieve one-click call! Mom doesn’t have to worry about your model anymore! Sample code:

Users can use the torch.hub.list() API to list all available entry points in the REPO. Say you want to know what computer vision models are available in PyTorch Hub: >>> Torch. Hub. List (' PyTorch/Vision ') >>> [' Alexnet ', 'deeplabv3_resnet101', 'densenet121',... In the previous step, you can see all the available computer vision models. If you want to call one of them, you don't have to install it. You can load the model in a single sentence. Model = torch.hub.load(' PyTorch/Vision ', 'deeplabv3_resnet101', pretrained=True) For detailed help on this model, use the following API:print(Torch.hub.help(' PyTorch/Vision ', 'deeplabv3_resnet101')) If the model's publishers subsequently add bug fixes and performance improvements, users can also easily get updates and make sure they are using the latest version: The model = torch. Hub. Load (... , force_reload=True) For other users, stability is more important, and they sometimes need to call code for a particular branch. For example, the hub branch of pytorch_GAN_zoo: Model = torch.hub. Load (' Facebookresearch /pytorch_GAN_zoo:hub ', pretrained=True, After loading the model from PyTorch Hub, you can use dir to view all available methods for the model. Take the bertForMaskedLM model as an example: >>> dir(model) >>> [' forward '... 'to' 'state_dict',] If you're interested in the forward method, use ithelpUnderstand the parameters required to run the method. >>>help(model.forward)
>>>
Help on method forward inmodule pytorch_pretrained_bert.modeling: Forward (input_ids, token_type_ids=None, attention_mask=None, masked_LM_labels =None)...Copy the code

38. Dg-net: Deep learning model training often requires a large amount of annotated data, but it is often difficult to collect and annotate a large amount of data. The author explores a method of generating data to assist training on the pedestrian re-recognition task. By generating high-quality pedestrian images (pedestrians changing clothes in pairs), it is integrated with the pedestrian re-recognition model to improve the quality of pedestrian generation and the accuracy of pedestrian re-recognition

  1. High-quality pedestrian images can be generated without additional annotations (such as pose, attribute, keypoints, etc.). By exchanging extracted features, the appearance of two pedestrian images can be exchanged. These appearances are real variations of the training set, not random noise.
  2. No part matching is required to enhance the result of pedestrian re-recognition. Simply showing the model more training samples can improve the model’s performance. Given N images, we first generate the training images of NxN, which are used to train the pedestrian re-recognition model. (The first line and the first column below are real image input, the rest are generated images)
  3. There is a cycle in training. The generated image is fed to the pedestrian re-recognition model to learn good pedestrian features, and the features extracted from the pedestrian re-recognition model are fed to the generated model to improve the quality of the generated image.
