- Storing Huge Volumes of Big Data
The very first and foremost challenge over the technology challenges of big data relates to the storing of huge quantities of data . As of now , there is no such computing machine with a storage thatis as big and enough to store the ongoing growing volume of data which has been a big cause of issue for most of the organisations engaged in the business of big data . Therefore , one should first try to store the huge quantity of data in manageable & inexpensive machines and then with upscaling prices and costs one could strive for better infrastructure . However , as it is customary with machines , machines are prone to getting failure at any random point of time and with more and more machines over the big data ecosystem , the chances of failure at any time may also becomes high . Each of the participative and implementable machines in the list could fail at some point or another and failure of a machine could entail a
loss of valuable data stored over them .
- So the first function of big data technology thus should be to store huge volumes of data within them and that too without incurring a high cost to the organization , while also combatting the risk of data loss . So all big data systems distribute data across a large cluster of inexpensive machines connected with each other over the big data network . This process also ensures that all of the data within the system is made failproof by ensuring that every piece of data is stored on multiple machines which would guarantee that at least one copy of the data is available to all the connected storage machines . All the above-mentioned processes are made fail-proof with the help of Hadoop which is a very well-known clustering technology of big data . Hadoop's data storage pattern is called as Hadoop Distributed File System (HDFS). This technology HDFS is built on the pattern's of Google's Big File Systems , which is designed to store billions of pages and sort the pages
to answer user search queries .

Training in Machine Learning
========================
- Training provides a learner algorithm with examples
of the desired inputs and also the results expected
from those inputs .The learner algorithm uses these
inputs to create a function
- Training in machine learning context is the process
where a learner algorithm maps a function to the data
and matches up with the inputs to their expected
Outputs

Back-propagation in machine learning
===============================
- Back-propagation or backward propagation of errors
is a method to determine the conditions under which
errors are removed form a neural network which is
built to resemble the human's neurons functions
by changing the weights and biases of the network
continually with a goal to arrive at an actual output
which would match the target output .
- The neurons present in the network catch the transmitted
information and relay the information along to
the next neuron in the line . And in this process , the
entire network is built for relaying the information from
the source of information propagation to the desired
target and in this way each neuron in the network is
shared a portion of the total information relayed and
as such all neurons keep passing information to next
neuron in line until the set of neurons create a final
Output .Thr total sum of errors at the rsult / target ise calculated by the method of Back-propagation

Question - Technology Challenges for Big Data
--------------------------------------------------------------
Ingesting Streams at an extremely fast pace . This
relates to the velocity of streaming of big data over
the enterprise systems . This velocity of big data
generally relates to the torrential and fast streams of
data . In some cases the velocity of the data streams
may be very large and fast to be stored , but still then
the pace of the data inflow should be monitored
and this can be done by creation of special purpose
ingesting systems that could open multiple number of
channels for receiving , utilisation and consumption
of the data . These ingesting systems could be used
for holding data in queues from which business
applications can read and process data at their own
pace and convenience.
The second layer and second most important purpose
to solve for big data systems is thus managing the
challenge posed by velocity of big data . And to deal
with this issue , special stream-processing engines
have been put in place where all the incoming data is
fed into a central queueing system over the network
of big data machines . From this system , a fork
shaped system sends data to the batch storage as well
as to the stream processing directions . These stream
processing engines can do the work of collection
of high velocity big data and send it to the batch
processing systems who stream the incoming data in
multiple batches and redistribute the volume among
the batch segregation systems . A most popular
system for this type of work handling is apache spark
which handles the work of streaming applications .

1) Machine Learning helps in detection of patterns in
all sorts of data sources
2) Machine Learning helps in creation of new models
based on the recognised patterns and behaviours
3) Machine Learning helps in making decisions
based on the success and failure of the patterns and
Behaviours

* Machine Learning works with Big Data in the form of networks and graphs ; raw data from sensors and internet , and the data collected is split into training and test data
* In Statistics , statistical models are created to create the prediction on smaller samples and further analysis for future
data based on earlier past data

=======================================
Machine Learning datasets require a huge amount
of memory . And , when such amount of memory is
required for vast amounts of data , then powerful
processors with multiple cores with high speeds would
also be necessitated . For this , better investments
in hardware for faster and efficient processing of the
datasets would also be required . So , for this sometimes
waiting for the model's solutions for best results
might take time for which scientists go for a useful
result in lieu of a right result when time is a constraint
The current state-of-the-art systems rely on Graphical
Processing Units(GPUs) to perform machine learning
tasks as they speed up the machine learning process
