Transformers are the essential parts of deep neural network, and widely used in Natural language processing tasks. We have a wide variety of usages where transformers are used in real time scenarios, such as, translations, text generation, question answering and various other NLP tasks. One of the widely used examples of transformer is Chat GPT. More information about transformer architecture and its mechanism can be accessed on page Understanding Transformers (BERT & GPT) . One of the very important processes in transformers is Finetuning. Finetuning is the way for adapting the OOB (out of the box) model for your specific tasks. In other words, it is the process of training a pre-trained model on your specific datasets to adapt the knowledge from new dataset. During fine-tuning, the parameters of the pre-trained model are adjusted based on the task-specific dataset. The goal is to adapt the model’s knowledge to perform well on the particular task of interest. Let’s understand how ...

Hyperparameters tuning is one of the most crucial steps of machine or deep learning process. Hyperparameters are configurations for a machine learning model that are not learned from the data but are set before the training process begins. These parameters are essential for controlling the overall behavior of the model. While training a machine learning model, you may have to experiment with different hyperparameters such as learning rate, batch size, dropout size, optimizers etc. in order to achieve the model with best accuracy. Performing experiments with hyperparameters one by one can be a tedious and time-consuming process. For instance, you initiate the training process with a specific combination of hyperparameters, and subsequently, you repeat the procedure with a different set of hyperparameters, and so forth. TensorFlow allows you to run experiments with different sets of hyperparameters in a single execution, enabling you to visualize the metrics on HParam dashboard in Tenso...

TensorBoard is a web-based tool to provide the visualizations and metrices needed during the machine learning process. TensorBoard is tightly integrated with TensorFlow and can be used seamlessly with it. It is highly efficient to track metrices like loss and accuracy, visualizing the model graph, histograms, and much more. Let’s understand more about how to collect metrices on TensorBoard and analyze those. TensorBoard as callback Consider the animal-building classification scenario in our post, Exploring CNN with TensorFlow & Keras . We have included TensorBoard as one of the callbacks while training the model. Callback is a tool to customize and extend the behavior of a model during training, evaluation, or inference, such as, model checkpointing (to periodically save your model during training), data augmentation (to increase the diversity of the training dataset), learning rate adjustments (dynamically adjust the learning rate during training based on certain conditions), T...
