In this example, a sine curve and a cosine curve are plotted in the same figure by superimposing the plots on top of each other.
# Plotting tutorials in Python
# Adding Multiple plots by superimposition
# Good for plots sharing similar x, y limits

Similar to the previous example, here, a sine and a cosine curve are plotted on the same figure using separate plot commands. This is more Pythonic and can be used to get separate handles for each plot.

There are two methods using which you can consume data from AWS S3 bucket.
Using sc.textFile (or sc.wholeTextFiles) API: This api can be used for HDFS and local file system as well.
aws_config = {} # set your aws credential here
sc._jsc.hadoopConfiguration().set("fs.s3n.awsSecretAccessK...

pry is a powerful tool that can be used to debug any ruby application. Setting up a ruby-on-rails application with this gem is very easy and straightforward.
Setup
To start debugging your application with pry
Add gem 'pry' to the application's Gemfile and bundle it
group :development, :test ...
In order to trigger a "upgradeneeded" event you need to request the database with version higher than the current version - otherwise the event won't be triggered.
function createTable(dbName, dbversion, tableName) {
var request = indexedDB.open(dbName, dbversion);
request.onupgrade...
This is a more generic solution applicable in system where the user has option to add indexes to the table that he uses:
function createTable(dbName, tableName) {
var request = indexedDB.open(dbName);
request.onsuccess = function (e){
var database = e.target.result;
var version = p...

Let's demonstrate the power of PLY with a simple example: this program will take an arithmetic expression as a string input, and attempt to solve it.
Open up your favourite editor and copy the following code:
from ply import lex
import ply.yacc as yacc
tokens = (
'PLUS',
'MINUS',

Ok, so now you have your layer designed! This is how you define it in your .prototxt file:
layer {
name: "LayerName"
type: "Python"
top: "TopBlobName"
bottom: "BottomBlobName"
python_param {
module: "My_Custom_Layer_File"

This example is a custom data layer, that receives a text file with image paths, loads a batch of images and preprocesses them. Just a quick tip, Caffe already has a big range of data layers and probably a custom layer is not the most efficient way if you just want something simple.

The goal of backpropagation is to optimize the weights so that the neural network can learn how to correctly map arbitrary inputs to outputs.
Each layer has its own set of weights, and these weights must be tuned to be able to accurately predict the right output given input.

Activation functions also known as transfer function is used to map input nodes to output nodes in certain fashion.
They are used to impart non linearity to the output of a neural network layer.
Some commonly used functions and their curves are given below:
