Data Analytics – GGPLOT AXIS TICKS: SET AND ROTATE TEXT LABELS

Hits: 74 GGPLOT AXIS TICKS: SET AND ROTATE TEXT LABELS   This article describes how to easily set ggplot axis ticks for both x and y axes. We’ll also explain how to rotate axis labels by specifying a rotation angle. In this R graphics tutorial, you will learn how to: Change the font style (size, color and face) of the axis …

Data Analytics – GGPLOT AXIS LIMITS AND SCALES

Hits: 14 GGPLOT AXIS LIMITS AND SCALES   This article describes R functions for changing ggplot axis limits (or scales). We’ll describe how to specify the minimum and the maximum values of axes. Among the different functions available in ggplot2 for setting the axis range, the coord_cartesian() function is the most preferred, because it zoom the plot without clipping the …

Learn Keras by Example – Preprocessing Data For Neural Networks

Hits: 8 Preprocessing Data For Neural Networks Typically, a neural network’s parameters are initialized (i.e. created) as small random numbers. Neural networks often behave poorly when the feature values much larger than parameter values. Furthermore, since an observation’s feature values will are combined as they pass through individual units, it is important that all features …

Learn Keras by Example – How to Build LSTM Recurrent Neural Network

Hits: 45 LSTM Recurrent Neural Network Oftentimes we have text data that we want to classify. While it is possible to use a type of convolutional network, we are going to focus on a more popular option: the recurrent neural network. The key feature of recurrent neural networks is that information loops back in the …
