Overview of this book

Machine learning (ML) helps you find hidden insights from your data without the need for explicit programming. This book is your key to solving any kind of ML problem you might come across in your job. You’ll encounter a set of simple to complex problems while building ML models, and you'll not only resolve these problems, but you’ll also learn how to build projects based on each problem, with a practical approach and easy-to-follow examples. The book includes a wide range of applications: from analytics and NLP, to computer vision domains. Some of the applications you will be working on include stock price prediction, a recommendation engine, building a chat-bot, a facial expression recognition system, and many more. The problem examples we cover include identifying the right algorithm for your dataset and use cases, creating and labeling datasets, getting enough clean data to carry out processing, identifying outliers, overftting datasets, hyperparameter tuning, and more. Here, you'll also learn to make more timely and accurate predictions. In addition, you'll deal with more advanced use cases, such as building a gaming bot, building an extractive summarization tool for medical documents, and you'll also tackle the problems faced while building an ML model. By the end of this book, you'll be able to fine-tune your models as per your needs to deliver maximum productivity.

Problems with the existing approach


In this section, we will list all the points that create problems. We should try to improve them. The following are things that I feel we can improve upon:

  • If you find out that class sampling is not proper in your case, then you can adopt the sampling methods

  • We can add more layers to our neural network

We can try different gradient descent techniques.

In this approach, training takes a lot of time that means training is computationally expensive. When we trained the model, we used GPUs even though GPU training takes a long time. We can use multiple GPUs, but that is expensive, and a cloud instance with multiple GPUs is not affordable. So, if we can use transfer learning in this application, or use the pre-trained model, then we will achieve better results.
