Machine Learning Basics
The course then delves into the basics of machine learning, explaining key concepts such as features, classification, and regression.
What Are Features?
Features are the building blocks of machine learning models. They’re variables that are used to train a model and make predictions. In this course, learners will gain an understanding of features and how they’re used in machine learning.
What is Classification?
Classification is a type of machine learning algorithm that’s used for predicting categorical outcomes. For example, if you want to predict whether someone is likely to buy a product or not, classification would be the appropriate algorithm to use.
What is Regression?
Regression is another type of machine learning algorithm that’s used for predicting continuous values. For example, if you want to predict a person’s salary based on their age and experience, regression would be the appropriate algorithm to use.
Training a Model and Preparing Data
The course then guides learners through the process of training a model and preparing data for machine learning tasks.
What is Training a Model?
Training a model involves using data to build a predictive model. This can include tuning hyperparameters, choosing the right algorithms, and selecting relevant features. In this course, learners will gain hands-on experience in training models using popular libraries such as TensorFlow.
What is Preparing Data?
Preparing data involves cleaning and processing it for use in machine learning tasks. This includes handling missing values, encoding categorical variables, and normalizing or scaling continuous variables. In this course, learners will gain hands-on experience in preparing data using popular libraries such as Pandas and NumPy.
Machine Learning Algorithms
The course covers several machine learning algorithms, including K-Nearest Neighbors (KNN), Naive Bayes, Logistic Regression, and Support Vector Machine (SVM).
What is K-Nearest Neighbors (KNN)?
KNN is a type of classification algorithm that’s used for predicting categorical outcomes. It works by finding the k-nearest neighbors to a given data point and using their labels to make a prediction.
What is Naive Bayes?
Naive Bayes is another type of classification algorithm that’s used for predicting categorical outcomes. It assumes that features are independent of each other and uses Bayes’ theorem to make predictions.
What is Logistic Regression?
Logistic Regression is a type of regression algorithm that’s used for predicting binary outcomes. It works by modeling the probability of an event occurring using a logistic function.
What is Support Vector Machine (SVM)?
SVM is a type of classification or regression algorithm that’s used for finding the best hyperplane to separate classes in feature space.
Neural Networks with TensorFlow
The course then transitions into Neural Networks, introducing learners to TensorFlow, a popular open-source platform for machine learning.
What is TensorFlow?
TensorFlow is an open-source software library for numerical computation. It was originally developed by Google and is widely used for building and training deep neural networks.
Building a Classification Neural Network with TensorFlow
In this section of the course, learners will gain hands-on experience in building a classification neural network using TensorFlow. This includes importing necessary libraries, defining the model architecture, compiling the model, and evaluating its performance.
Linear Regression
The course also covers Linear Regression, a fundamental algorithm in machine learning.
What is Linear Regression?
Linear Regression is a type of regression algorithm that’s used for predicting continuous values. It works by modeling the relationship between features and a target variable using a linear equation.
Implementing Linear Regression
In this section of the course, learners will gain hands-on experience in implementing Linear Regression using popular libraries such as Scikit-learn.
Using a Neuron for Linear Regression
Neurons are fundamental components of neural networks. In this section of the course, learners will gain an understanding of how to use a neuron for Linear Regression.
What is a Neuron?
A neuron is a mathematical function that’s used to model complex relationships between features and a target variable.
