- 12. Features of Machine Learning Let us look at some of the features of Machine Learning. •Machine Learning is computing-intensive and generally requires a large amount of training data. •It involves repetitive training to improve the learning and decision making of algorithms. •As more data gets added, Machine Learning training can be automated for learning new data patterns and adapting its algorithm.
- 13. Machine Learning Algorithms • Machine Learning can learn from labeled data (known as supervised learning) or unlabelled data (known as unsupervised learning). • Machine Learning algorithms involving unlabelled data, or unsupervised learning, are more complicated than those with the labeled data or supervised learning • Machine Learning algorithms can be used to make decisions in subjective areas as well.
- 14. Examples • Logistic Regression can be used to predict which party will win at the ballots. • Naïve Bayes algorithm can separate valid emails from spam. • Face detection: Identify faces in images (or indicate if a face is present). • Email filtering: Classify emails into spam and not- spam. • Medical diagnosis: Diagnose a patient as a sufferer or non-sufferer of some disease. • Weather prediction: Predict, for instance, whether or not it will rain tomorrow.
- 15. Libraries and Packages • To understand machine learning, you need to have basic knowledge of Python programming. In addition, there are a number of libraries and packages generally used in performing various machine learning tasks as listed below: – NumPy - is used for its N-dimensional array objects – pandas – is a data analysis library that includes data frames – matplotlib – is 2D plotting library for creating graphs and plots – scikit-learn - the algorithms used for data analysis and data mining tasks – seaborn – a data visualization library based on matplotlib
- 16. Importing and Utilizing Packages 1 Installation Packages are typically installed using package managers like pip or conda. 2 Importing Packages are imported using standard import statements at the beginning of your code. 3 Usage Access package functions and classes through dot notation, e.g. package.function().
- 17. Optimizing Package Performance Profiling Identify performance bottlenecks with profiling tools. Parallelization Leverage multiprocessing and GPU acceleration for faster computations. Caching Implement caching mechanisms to reuse intermediate results. Optimization Tune hyperparameters and model architectures for efficiency.
- 18. Developing Custom Packages Package Structure Organize your code into a hierarchical directory structure with an __init__.py file.
