- Prove the linear relation of logistic regression by assuming that our Gaussian distributions share the same covariance matrix.
- Change the learning rate of the optimizer and see how the loss value is increased/decreased in iterations.
- Try to find the mapping function so that you can convert our non-linearly separable samples into linearly separable data points.
- What will happen if the bias vector is not added to the input data?
- What will happen if the loss function is changed? Change it to each of the following:
- Mean squared error (tf.losses.meanSquaredError)
- Absolute error (tf.losses.absoluteDifference)
- Weighted loss (tf.losses.computeWeightedLoss)
- Let's try to implement multiclass logistic regression that supports three-class predictions.
- Hint: Combine two logistic regression models to do binary classification twice.
- Save and load the logistic regression...

Overview of this book
TensorFlow.js is a framework that enables you to create performant machine learning (ML) applications that run smoothly in a web browser. With this book, you will learn how to use TensorFlow.js to implement various ML models through an example-based approach.
Starting with the basics, you'll understand how ML models can be built on the web. Moving on, you will get to grips with the TensorFlow.js ecosystem to develop applications more efficiently. The book will then guide you through implementing ML techniques and algorithms such as regression, clustering, fast Fourier transform (FFT), and dimensionality reduction. You will later cover the Bellman equation to solve Markov decision process (MDP) problems and understand how it is related to reinforcement learning. Finally, you will explore techniques for deploying ML-based web applications and training models with TensorFlow Core. Throughout this ML book, you'll discover useful tips and tricks that will build on your knowledge.
By the end of this book, you will be equipped with the skills you need to create your own web-based ML applications and fine-tune models to achieve high performance.
