Time Series Forecasting with RNNs – Towards Data Science


In some cases you may have input sequences that are too long and can cause the training to fail because of GPU memory issues or slow it down significantly. To deal with this issue, the model convolves the input sequence with a 1D convolution that has the same kernel size and stride before feeding it to the RNN encoder. This reduces the RNN input by a factor of n where n is the convolution kernel size. Context layer sits between the inputs encoder and a decoder layer. It concatenates encoder final state [S] with static features and static embeddings and produces a fixed size vector [C] which is then used as an initial state for the decoder.

The predict function in Python is Y X * Beta, where Y is a column vector, X is the design matrix, and Beta is the column vector of parameters. You could definitely programmatically create the equation in the form that you want though. I don't what function/module you are using for your regression. Are you processing the data into polynomial features, then feeding that to a linear regression model? You just have to feed it the original column names.

Declining mammal populations linked to Burmese python

Daily Mail - Science & tech

The Burmese python, an invasive species of snake in the Florida Everglades, has been linked to declining mammal populations in the area. The species of python has decimated populations of rabbits, deer, raccoons and other mammals. Rodents, however, have persisted - and a species of mosquito has been'forced' to feed on the rats, which carry the Everglades virus. The mosquito transmits the virus, and this could put humans and greater risk to exposure. According to the researchers at the University of Florida, the hispid cotton rat happens to be one of the only known natural hosts of Everglades virus, a pathogen that causes encephalitis - inflammation of the brain.

How To Extract Feature Vectors From Deep Neural Networks In Python Caffe


Convolutional Neural Networks are great at identifying all the information that makes an image distinct. When we train a deep neural network in Caffe to classify images, we specify a multilayered neural network with different types of layers like convolution, rectified linear unit, softmax loss, and so on. The last layer is the output layer that gives us the output tag with the corresponding confidence value. But sometimes it's useful for us to extract the feature vectors from various layers and use it for other purposes. Let's see how to do it in Python Caffe, shall we?

Machine Learning Classification: A Dataset-based Pictorial


The concept of classification in machine learning is concerned with building a model that separates data into distinct classes. This model is built by inputting a set of training data for which the classes are pre-labeled in order for the algorithm to learn from. The model is then used by inputting a different dataset for which the classes are withheld, allowing the model to predict their class membership based on what it has learned from the training set. Well-known classification schemes include decision trees and Support Vector Machines, among a whole host of others. As this type of algorithm requires explicit class labeling, classification is a form of supervised learning.
