### How to Load Data into an SVM Supervised Learning Model

For predictive analytics, you need to load the data for your algorithms to use. Loading the Iris dataset in scikit is as simple as issuing a couple of lines of code because [more…]

### How to Create an Unsupervised Learning Model with DBSCAN

DBSCAN (Density-Based Spatial Clustering of Applications with Noise) is a popular clustering algorithm used as an alternative to K-means in predictive analytics. It doesn’t require that you input the number [more…]

### Basics of Classification Models for Analytical Predictions

Once you have all the tools and data necessary to start creating a predictive model, the fun begins. In general, creating a learning model for classification tasks will entail the following steps: [more…]

### Why Visualization Matters for Predictive Analytics

Reading rows of spreadsheets, scanning pages and pages of reports, and going through stacks of analytical results generated by predictive models can be painstaking, time-consuming, and — let’s face it [more…]

### How to Run Training Data in an SVM Supervised Learning Model

Before you can feed the Support Vector Machine (SVM) classifier with the data that was loaded for predictive analytics, you must split the full dataset into a training set and test set. [more…]

### How to Visualize the Classifier in an SVM Supervised Learning Model

The Iris dataset is not easy to graph for predictive analytics in its original form because you cannot plot all four coordinates (from the features) of the dataset onto a two-dimensional screen. Therefore [more…]

### How to Run Test Data and Evaluate an SVM Supervised Learning Model

*Supervised learning* is a machine-learning task that learns from predictive analysis data that has been labeled. One way to think about supervised learning is that the labeling of data is done under the [more…]

### How to Create and Run an Unsupervised Learning Model to Make Predictions with K-Means

The K-means algorithm requires one initialization parameter from the user in order to create an instance for predictive analytics. It needs to know how many [more…]

### How to Evaluate an Unsupervised Learning Model with K-Means

After you’ve chosen your number of clusters for predictive analytics and have set up the algorithm to populate the clusters, you have a predictive model. You can make predictions based on new incoming [more…]

### How to New Analytical Predictions with R Regression

To make analytical predictions with new data, you simply use the function with a list of the seven attribute values. The following code does that job: [more…]

### Basics of Variables in R Programming for Predictive Analytics

Because it was designed for statistical analysis, the programming language R can be very useful for predicting outcomes based on a set of data. In order to use R, you first must know how to use variables [more…]

### Basics of Static and Streamed Data in Predictive Analyics

Data in predictive analytics can be identified as streamed, static, or a mix of the two. *Streamed data* changes continuously; examples include the constant stream of Facebook updates, tweets on Twitter, [more…]
