Deep Learning Network explanation

I prefer to read the scientific paper a lot, But here is the blog which I refer to anyone who is interested.

The blog provides the following.

1. Working

2. Architecture

3. References

Blogger : swethatanamala very good explanation of Deep learning network.

I would like to appreciate Mr wlouyang for sharing basic knowledge to kick start in computer vision.

check shape of array in numpy and tensorflow

Numpy : its a python module/package to perform scientific computation on arrays.

How to install numpy package in anaconda

>> pip install  numpy

or

>> conda install numpy

To check if numpy package is  installed or not use

>> conda list
output :
>> numpy                     1.14.2

Once the package is installed you can import into you application

ex : import numpy

Basic numpy operation on Array :

>>> input = np.array([[1,2,3],[2,3,4]])
>>> input.shape
>>> (2, 3)


Ex : In digit recognition using tensorflow we can get shape

import tensorflow as tf
mnist = tf.keras.datasets.mnist
import numpy as np
print( tf.__version__)
(x_train, y_train),(x_test, y_test) = mnist.load_data()

print(x_train.shape);
>> (60000, 28, 28)
print( x_train[0].shape)

>> (28, 28) 

Note :
1. Tensorflow | keras| framework is used.
2. Mnist database for digit recognition

Recreational Music Making (RMM) for Working Adults

Recreational Music Making (RMM) has been scientifically proven to help the U.S. workplace by:

Reducing employee stress
Reducing employee depression
Reducing employee burnout
Improving employee retention

• Employee stress is expensive for companies and widespread. Research shows that the economic impact is estimated at $300 billion each year (Source: New York Times). Experts claim that 60 to 90 percent of doctor visits involve stress-related complaints.
• Engaging in RMM reduces stress. RMM has been shown to reverse the body’s response to stress at the DNA level (Source: Dr. Barry Bittman).
• Depression is widespread in the workforce and is expensive for companies. The economic impact of depression in the workplace is estimated at $34 billion annually—$11 billion for treatment, $11 billion in decreased productivity, and $12 billion in absenteeism. Depression affects about 19 million people, 70 percent of whom are in the workforce. (Figures are according to Braun Consulting News).
• Engaging in RMM reduces depression. Recent research with long-term care workers showed reduced depression (21.8 percent) six weeks after the completion of an RMM program consisting of one hour per week. (Source: A 2003 study conducted by Trip Umbach Healthcare Consulting, Inc.)
• RMM can help companies reduce turnover, saving them millions. The research with long-term care workers showed an 18.3 percent overall reduction of employee turnover by implementing an RMM program. The total annual savings was projected at $1.46 billion.

Every worker can participate in RMM. There are no physical limitations or requirements.
