Mastering Hyperparameter Tuning & Neural Network Architectures: Exploring Bayesian Optimization_ Day 19

In conclusion, Bayesian optimization does not change the internal structure of the model—things like the number of layers, the activation functions, or the gradients. Instead, it focuses on external hyperparameters. These are settings that control how the model behaves during training and how it processes the data, but they are not part of the model’s architecture itself. For instance, in this code, Bayesian optimization adjusts: So, while the model’s internal structure—like layers and activations—remains unchanged, Bayesian optimization helps you choose the best external hyperparameters. This results in a better-performing model without needing to re-architect or directly modify the model’s components....

Sequential vs Functional Keras API Part 2 explanation _ Day 15

Keras API Example Let’s continue from day 14 which we explained the 3 Keras API types and compare them Understanding Sequential vs. Functional API in Keras with a Simple Example When building neural networks in Keras, there are two main ways to define models: the Sequential API and the Functional API. In this post, we’ll explore the differences between these two approaches using a simple mathematical example. Sequential API The Sequential API in Keras is a linear stack of layers. It’s easy to use but limited to single-input, single-output stacks of layers. Here’s a simple example to illustrate how it...
