# EWMA [![GoDoc](https://godoc.org/github.com/VividCortex/ewma?status.svg)](https://godoc.org/github.com/VividCortex/ewma) ![Build Status](https://circleci.com/gh/VividCortex/moving_average.png?circle-token=1459fa37f9ca0e50cef05d1963146d96d47ea523)
This repo provides Exponentially Weighted Moving Average algorithms, or EWMAs for short, [based on our
Quantifying Abnormal Behavior talk](https://vividcortex.com/blog/2013/07/23/a-fast-go-library-for-exponential-moving-averages/).
### Exponentially Weighted Moving Average
An exponentially weighted moving average is a way to continuously compute a type of
average for a series of numbers, as the numbers arrive. After a value in the series is
added to the average, its weight in the average decreases exponentially over time. This
biases the average towards more recent data. EWMAs are useful for several reasons, chiefly
their inexpensive computational and memory cost, as well as the fact that they represent
the recent central tendency of the series of values.
The EWMA algorithm requires a decay factor, alpha. The larger the alpha, the more the average
is biased towards recent history. The alpha must be between 0 and 1, and is typically
a fairly small number, such as 0.04. We will discuss the choice of alpha later.
The algorithm works thus, in pseudocode:
1. Multiply the next number in the series by alpha.
2. Multiply the current value of the average by 1 minus alpha.
3. Add the result of steps 1 and 2, and store it as the new current value of the average.
4. Repeat for each number in the series.
There are special-case behaviors for how to initialize the current value, and these vary
between implementations. One approach is to start with the first value in the series;
another is to average the first 10 or so values in the series using an arithmetic average,
and then begin the incremental updating of the average. Each method has pros and cons.
It may help to look at it pictorially. Suppose the series has five numbers, and we choose
alpha to be 0.50 for simplicity. Here's the series, with numbers in the neighborhood of 300.
![Data Series](https://user-images.githubusercontent.com/279875/28242350-463289a2-6977-11e7-88ca-fd778ccef1f0.png)
Now let's take the moving average of those numbers. First we set the average to the value
of the first number.
![EWMA Step 1](https://user-images.githubusercontent.com/279875/28242353-464c96bc-6977-11e7-9981-dc4e0789c7ba.png)
Next we multiply the next number by alpha, multiply the current value by 1-alpha, and add
them to generate a new value.
![EWMA Step 2](https://user-images.githubusercontent.com/279875/28242351-464abefa-6977-11e7-95d0-43900f29bef2.png)
This continues until we are done.
![EWMA Step N](https://user-images.githubusercontent.com/279875/28242352-464c58f0-6977-11e7-8cd0-e01e4efaac7f.png)
Notice how each of the values in the series decays by half each time a new value
is added, and the top of the bars in the lower portion of the image represents the
size of the moving average. It is a smoothed, or low-pass, average of the original
series.
For further reading, see [Exponentially weighted moving average](http://en.wikipedia.org/wiki/Moving_average#Exponential_moving_average) on wikipedia.
### Choosing Alpha
Consider a fixed-size sliding-window moving average (not an exponentially weighted moving average)
that averages over the previous N samples. What is the average age of each sample? It is N/2.
Now suppose that you wish to construct a EWMA whose samples have the same average age. The formula
to compute the alpha required for this is: alpha = 2/(N+1). Proof is in the book
"Production and Operations Analysis" by Steven Nahmias.
So, for example, if you have a time-series with samples once per second, and you want to get the
moving average over the previous minute, you should use an alpha of .032786885. This, by the way,
is the constant alpha used for this repository's SimpleEWMA.
### Implementations
This repository contains two implementations of the EWMA algorithm, with different properties.
The implementations all conform to the MovingAverage interface, and the constructor returns
that type.
Current implementations assume an implicit time interval of 1.0 between every sample added.
That is, the passage of time is treated as though it's the same as the arrival of samples.
If you need time-based decay when samples are not arriving precisely at set intervals, then
this package will not support your needs at present.
#### SimpleEWMA
A SimpleEWMA is designed for low CPU and memory consumption. It **will** have different behavior than the VariableEWMA
for multiple reasons. It has no warm-up period and it uses a constant
decay. These properties let it use less memory. It will also behave
differently when it's equal to zero, which is assumed to mean
uninitialized, so if a value is likely to actually become zero over time,
then any non-zero value will cause a sharp jump instead of a small change.
#### VariableEWMA
Unlike SimpleEWMA, this supports a custom age which must be stored, and thus uses more memory.
It also has a "warmup" time when you start adding values to it. It will report a value of 0.0
until you have added the required number of samples to it. It uses some memory to store the
number of samples added to it. As a result it uses a little over twice the memory of SimpleEWMA.
## Usage
### API Documentation
View the GoDoc generated documentation [here](http://godoc.org/github.com/VividCortex/ewma).
```go
package main
import "github.com/VividCortex/ewma"
func main() {
samples := [100]float64{
4599, 5711, 4746, 4621, 5037, 4218, 4925, 4281, 5207, 5203, 5594, 5149,
}
e := ewma.NewMovingAverage() //=> Returns a SimpleEWMA if called without params
a := ewma.NewMovingAverage(5) //=> returns a VariableEWMA with a decay of 2 / (5 + 1)
for _, f := range samples {
e.Add(f)
a.Add(f)
}
e.Value() //=> 13.577404704631077
a.Value() //=> 1.5806140565521463e-12
}
```

# Multi Progress Bar
[![GoDoc](https://godoc.org/github.com/vbauerster/mpb?status.svg)](https://godoc.org/github.com/vbauerster/mpb)
[![Build Status](https://travis-ci.org/vbauerster/mpb.svg?branch=master)](https://travis-ci.org/vbauerster/mpb)
[![Go Report Card](https://goreportcard.com/badge/github.com/vbauerster/mpb)](https://goreportcard.com/report/github.com/vbauerster/mpb)
[![codecov](https://codecov.io/gh/vbauerster/mpb/branch/master/graph/badge.svg)](https://codecov.io/gh/vbauerster/mpb)
**mpb** is a Go lib for rendering progress bars in terminal applications.
## Features
* __Multiple Bars__: Multiple progress bars are supported
* __Dynamic Total__: [Set total](https://github.com/vbauerster/mpb/issues/9#issuecomment-344448984) while bar is running
* __Dynamic Add/Remove__: Dynamically add or remove bars
* __Cancellation__: Cancel whole rendering process
* __Predefined Decorators__: Elapsed time, [ewma](https://github.com/VividCortex/ewma) based ETA, Percentage, Bytes counter
* __Decorator's width sync__: Synchronized decorator's width among multiple bars
## Installation
```sh
go get github.com/vbauerster/mpb
```
_Note:_ it is preferable to go get from github.com, rather than gopkg.in. See issue [#11](https://github.com/vbauerster/mpb/issues/11).
## Usage
#### [Rendering single bar](examples/singleBar/main.go)
```go
p := mpb.New(
// override default (80) width
mpb.WithWidth(64),
// override default "[=>-]" format
mpb.WithFormat("╢▌▌░╟"),
// override default 120ms refresh rate
mpb.WithRefreshRate(180*time.Millisecond),
)
total := 100
name := "Single Bar:"
// adding a single bar
bar := p.AddBar(int64(total),
mpb.PrependDecorators(
// display our name with one space on the right
decor.Name(name, decor.WC{W: len(name) + 1, C: decor.DidentRight}),
// replace ETA decorator with "done" message, OnComplete event
decor.OnComplete(
// ETA decorator with ewma age of 60, and width reservation of 4
decor.EwmaETA(decor.ET_STYLE_GO, 60, decor.WC{W: 4}), "done",
),
),
mpb.AppendDecorators(decor.Percentage()),
)
// simulating some work
max := 100 * time.Millisecond
for i := 0; i < total; i++ {
start := time.Now()
time.Sleep(time.Duration(rand.Intn(10)+1) * max / 10)
// ewma based decorators require work duration measurement
bar.IncrBy(1, time.Since(start))
}
// wait for our bar to complete and flush
p.Wait()
```
#### [Rendering multiple bars](examples/simple/main.go)
```go
var wg sync.WaitGroup
p := mpb.New(mpb.WithWaitGroup(&wg))
total, numBars := 100, 3
wg.Add(numBars)
for i := 0; i < numBars; i++ {
name := fmt.Sprintf("Bar#%d:", i)
bar := p.AddBar(int64(total),
mpb.PrependDecorators(
// simple name decorator
decor.Name(name),
// decor.DSyncWidth bit enables column width synchronization
decor.Percentage(decor.WCSyncSpace),
),
mpb.AppendDecorators(
// replace ETA decorator with "done" message, OnComplete event
decor.OnComplete(
// ETA decorator with ewma age of 60
decor.EwmaETA(decor.ET_STYLE_GO, 60), "done",
),
),
)
// simulating some work
go func() {
defer wg.Done()
max := 100 * time.Millisecond
for i := 0; i < total; i++ {
start := time.Now()
time.Sleep(time.Duration(rand.Intn(10)+1) * max / 10)
// ewma based decorators require work duration measurement
bar.IncrBy(1, time.Since(start))
}
}()
}
// wait for all bars to complete and flush
p.Wait()
```

for i := 0; i < count; i++ {

}
```
Result will be like this:
```
> go run test.go
37158 / 100000 [================>_______________________________] 37.16% 1m11s
```
## Customization
```Go
// create bar
bar := pb.New(count)
// refresh info every second (default 200ms)
bar.SetRefreshRate(time.Second)
// show percents (by default already true)
bar.ShowPercent = true
// show bar (by default already true)
bar.ShowBar = true
// no counters
bar.ShowCounters = false
// show "time left"
bar.ShowTimeLeft = true
// show average speed
bar.ShowSpeed = true
// sets the width of the progress bar
bar.SetWidth(80)
// sets the width of the progress bar, but if terminal size smaller will be ignored
bar.SetMaxWidth(80)
// convert output to readable format (like KB, MB)
bar.SetUnits(pb.U_BYTES)
// and start
bar.Start()
```
## Progress bar for IO Operations
```go
// create and start bar
bar := pb.New(myDataLen).SetUnits(pb.U_BYTES)
bar.Start()
// my io.Reader
r := myReader
// my io.Writer
w := myWriter
// create proxy reader
reader := bar.NewProxyReader(r)
// and copy from pb reader
io.Copy(w, reader)
```
```go
// create and start bar
bar := pb.New(myDataLen).SetUnits(pb.U_BYTES)
bar.Start()
// my io.Reader
r := myReader
// my io.Writer
w := myWriter
// create multi writer
writer := io.MultiWriter(w, bar)
// and copy
io.Copy(writer, r)
bar.Finish()
```
## Custom Progress Bar Look-and-feel
```go
bar.Format("<.- >")
```
## Multiple Progress Bars (experimental and unstable)
Do not print to terminal while pool is active.
```go
package main
import (
"math/rand"
"sync"
"time"
"gopkg.in/cheggaaa/pb.v1"
)
func main() {
// create bars
first := pb.New(200).Prefix("First ")
second := pb.New(200).Prefix("Second ")
third := pb.New(200).Prefix("Third ")
// start pool
pool, err := pb.StartPool(first, second, third)
if err != nil {
panic(err)
}
// update bars
wg := new(sync.WaitGroup)
for _, bar := range []*pb.ProgressBar{first, second, third} {
wg.Add(1)
go func(cb *pb.ProgressBar) {
for n := 0; n < 200; n++ {
cb.Increment()
time.Sleep(time.Millisecond * time.Duration(rand.Intn(100)))
}
cb.Finish()
wg.Done()
}(bar)
}
wg.Wait()
// close pool
pool.Stop()
}
```
The result will be as follows:
```
$ go run example/multiple.go
First 34 / 200 [=========>---------------------------------------------] 17.00% 00m08s
Second 42 / 200 [===========>------------------------------------------] 21.00% 00m06s
Third 36 / 200 [=========>---------------------------------------------] 18.00% 00m08s
```
