tfm.optimization.lr_schedule.LinearWarmup Instantiates a LearningRateSchedule from its config. A LearningRateSchedule that uses a cosine decay with optional warmup. tfm.optimization.lr_schedule.CosineDecayWithOffset See Loshchilov & Hutter, ICLR2016, SGDR: Stochastic Gradient Descent with Warm Restarts. For the idea of a linear warmup of our learning rate, see Goyal et al..

When we begin training a model, we often want an initial increase in our learning rate followed by a decay. If warmup_target is an int, this schedule applies a linear increase per optimizer step to our learning rate from initial_learning_rate to warmup_target for a duration of warmup_steps. Afterwards, it applies a cosine decay function taking our learning rate from warmup_target to alpha for a duration of decay_steps. If warmup_target is None we skip warmup and our decay will take our learning rate from initial_learning_rate to alpha. It requires a step value to compute the learning rate. You can just pass a TensorFlow variable that you increment at each training step.

Optimizer that implements the Layer-wise Adaptive Moments (LAMB). See paper Large Batch Optimization for Deep Learning: Training BERT in 76 minutes. If set, clips gradients to a maximum norm. Check tf.clip_by_global_norm for more details. A slot variable is an additional variable associated with var to train. It is allocated and managed by optimizers, e.g.

Adam. This section contains additional collections of API reference pages for projects and packages separate from the tensorflow package, but that do not have dedicated subsite pages. The TensorFlow Models repository provides implementations of state-of-the-art (SOTA) models. The official/projects directory contains a collection of SOTA models that use TensorFlow’s high-level API. They are intended to be well-maintained, tested, and kept up-to-date with the latest TensorFlow API. The library code used to build and train these models is available as a pip package.

The TensorFlow Model Optimization Toolkit is a suite of tools that users, both novice and advanced, can use to optimize machine learning models for deployment and execution. Supported techniques include quantization and pruning for sparse weights. There are APIs built specifically for Keras.

For an overview of this project and individual tools, the optimization gains, and our roadmap refer to tensorflow.org/model_optimization. The website also provides various tutorials and API docs. The toolkit provides stable Python APIs. For installation instructions, see tensorflow.org/model_optimization/guide/install. tfm.optimization.optimizer_factory.OptimizerFactory This class builds learning rate and optimizer based on an optimization config.

To use this class, you need to do the following: (1) Define optimization config, this includes optimizer, and learning rate schedule. (2) Initialize the class using the optimization config. (3) Build learning rate. (4) Build optimizer. This is a typical example for using this class: Builds learning rate from config.

Learning rate schedule is built according to the learning rate config. If learning rate type is consant, lr_config.learning_rate is returned. Builds optimizer from config. It takes learning rate as input, and builds the optimizer according to the optimizer config. Typically, the learning rate built using self.build_lr() is passed as an argument to this method.

No ads, dark-mode and 6 months free of IntelliJ Idea Ultimate to start with. When we’re training neural networks, choosing the learning rate (LR) is a crucial step. This value defines how each pass on the gradient changes the weights in each layer. In this tutorial, we’ll show how different strategies for defining the LR affect the accuracy of a model. We’ll consider the warm-up scenario, which only includes a few initial iterations. For a more theoretical aspect of it, we refer to another article of ours.

Here, we’ll focus on the implementation aspects and performance comparison of different approaches. To keep things simple, we use the well-known fashion MNIST dataset. Let’s start by loading the required libraries and this computer vision dataset with labels:
