- If two samples have a Minkowski distance (p=5) equal to 10, what can you say about their Manhattan distance?
- The main factor that negatively impacts on the convergence speed of K-means is the dimensionality of the dataset. Is this correct?
- One of the most important factors that can positively impact on the performance of K-means is the convexity of the clusters. Is this correct?
- The homogeneity score of a clustering application is equal to 0.99. What does it mean?
- What is the meaning of an adjusted Rand score equal to -0.5?
- Considering the previous question, can a different number of clusters yield a better score?
- An application based on KNN requires on average 100 5-NN base queries per minute. Every minute, 2 50-NN queries are executed (each of them requires 4 seconds with a leaf size=25) and, immediately after them, a 2-second blocking task is performed. Assuming...

Overview of this book
Unsupervised learning is about making use of raw, untagged data and applying learning algorithms to it to help a machine predict its outcome. With this book, you will explore the concept of unsupervised learning to cluster large sets of data and analyze them repeatedly until the desired outcome is found using Python.
This book starts with the key differences between supervised, unsupervised, and semi-supervised learning. You will be introduced to the best-used libraries and frameworks from the Python ecosystem and address unsupervised learning in both the machine learning and deep learning domains. You will explore various algorithms, techniques that are used to implement unsupervised learning in real-world use cases. You will learn a variety of unsupervised learning approaches, including randomized optimization, clustering, feature selection and transformation, and information theory. You will get hands-on experience with how neural networks can be employed in unsupervised scenarios. You will also explore the steps involved in building and training a GAN in order to process images.
By the end of this book, you will have learned the art of unsupervised learning for different real-world challenges.
