examples. Data Augmentation is a set of techniques which leverage the original training data to generate more training examples without having to label them. We’ll familiarize ourselves with these techniques identical to the original sample. A slightly tilted cat is still a cat! The label mixing transformations generate samples based on differently labeled inputs. The target label is a composite of the inputs that 30% and a ‘hamster’ with a probability of 70%. The sample generation techniques use models to generate samples for labels.

For 5 trials, one possible trial set can be and for 7 trials, one their NAS model could generate variable depth child networks. Figure 7-4 shows a sketch of their search procedure. It involves a controller which samples the search space to generate candidate architectures rewards are determined by their performance on the target dataset. The controller model learns to generate better architectures as the search game progresses. Figure 7-4: An overview of Neural Architecture0 码力 | 33 页 | 2.48 MB | 1 年前3keras tutorial

Both these models have been deployed in production accurate model (teacher) which might not be suitable for deployment. The larger model is used to generate soft labels on the training data, and the student model learns to copy both the ground-truth labels generates candidate models.

concept). Here is a quick recipe to train embedding-based models: 1. Embedding Table Generation: Generate the embeddings for the inputs using machine learning algorithms of your choice. 2. Embedding Lookup: to a single vector. The result is passed through a few dense layers and a softmax activation to generate an output tensor of size num_classes. This is similar to the Word2Vec example except the fact that specifically learn representations by showing similar and dissimilar inputs, and forcing the model to generate embeddings that have a small distance between each other for similar inputs, and a large distance0 码力 | 53 页 | 3.92 MB | 1 年前3《Efficient Deep Learning Book》[EDL] Chapter 5 - Advanced Compression Techniques
