machine learning is used in
data center anagement
to save energy and improve service quality
how to synchronise VM state?
stop and copy=== stop the source, copy the source Vm and
qurantine to cloud computing

whats cloud cmputing and trying to use it
covid -19
how to protect o self-clean yo hands, keep social distance and quarantine and ware masks
social distance and quarante most effect
but class cant be gone..unless u use online classes means lots of data. covid had increased dat via online thus big data. the servers dont have enough capacit to hold so much burst.
cloud computing comes in to help bse its elastic features and on demand in usage
cloud computing has grown faster than big data and machine learning
google is the champion in cloud computng
classic application of big data technology
bigdata computing model and construction perspctive
BI-business intellengency
AI-artificial intelegency
Neuroscience background
deep learning-recurrent structure
experiment
theory
calculation
data
whole sample instead of sampling
efficuency rather than precision
related rather than causal
deep learning -any learning methor that can train a system with more than 2 or 3 non liear hidden layers
convolution neural network
sparse connectivity each neural only connects to part of the output of the previous layer
parameter sharing the neurons withdiffirent receptive fields can use the same set of parameters
less parameters than fully connected layer
deep learning
.deep learning
machine learning
why machine learning-recognizing patterns, recognizing anomalies, prediction
massive parallelism, huge data volumes stoae, data distribution, highspeed networks,etc
bigdata is every where.big data offers time advantage and data mining
mapreduce, hadoop, locality sensitive hashing
data parallel and model parallel
-volume- size and skill
velocity -geneerated at high speed
and variety, -variety like images, tables etc
veracity- uncertainty of the data
-it exceeds the processing capacity
big data is data that exceeds the processing capacity of conventional database systems. the data is too big , moves to fast or doesnt fit the structures of your databas
challenges in big data:
1) problem with storage
More data allows us
to see new aspects, see better aspects, see different aspects
more data..more information.
-examples facebook, an internet minute, smart phone users, big data is smilar to sall dat but bigger and requires diffirent approaches like techniques, tools and architctres to solve new problemms and old probles in abetter way.
it will bring challanges in volumes ,process and arigorithms
-what is the value of big data
-helps to track adays movement/estimate adays routine
-helps to know the emotion variations on national days
-helps with scene completion problems
data is mined so as to establish consumer emotion and trend.
