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.

Testing the baseline model


In this section, we will run the baseline model. In order to run the script, we need to jump to the location where we put the script titled real_time_object_detection.py and, on Command Prompt, we need to execute the following command:

Figure 9.13: Execution of the baseline approach

Take a look at the following figure. Here, I have just placed example images, but you can see the entire video when you run the script. Here is the link to see the entire video for real-time object detection using the baseline approach: https://drive.google.com/drive/folders/1RwKEUaxTExefdrSJSy44NugqGZaTN_BX?usp=sharing.

Here, the mAP for the MobileNet SSD is 71.1% . You will learn how to optimize this approach in the upcoming section. First, we will list down the points that we can improve in the next iteration. So, let's jump to our next section.
