5. Machine Learning Specialization
The Machine Learning Major is a foundational online program developed in collaboration between DeepLearning.AI and Stanford Online. This beginner-friendly program will teach you the basics of machine learning and how to use this technique to create real-world AI applications.
This specialization is taught by Andrew Ng, an AI visionary who has led critical research at Stanford University and pioneering work on Google Brain, Baidu, and Landing.AI advancing AI.
This 3-course specialization is the latest version of Andrew’s breakthrough Machine Learning course, which has a 4.9 out of 5 ratings and has been taken by over 4.8 million students since its launch in 2012.
Provides a broad introduction to modern machine learning, including supervised learning (multiple linear regression, logistic regression, neural networks, and decision trees), unsupervised learning (clustering, dimensionality reduction, recommender systems), and some of the best practices used in Silicon Valley for artificial intelligence innovation and machine learning (model evaluation and optimization, data-driven approaches to performance improvement, etc.)
WHAT YOU WILL LEARN
Build ML models with NumPy & sci-kit-learn, build and train supervised models for prediction tasks and binary classification (linear, logistic regression)
Build and train neural networks with TensorFlow to perform multiclass classification and to create and use decision trees and ensemble tree methods
Apply best practices for machine learning development and use unsupervised learning techniques for unsupervised learning, including clustering and anomaly detection
Build a recommender system with a collaborative filtering approach and a content-based deep learning methodology and build a deep reinforcement learning model
