  2. 2. The status quo • Data, Data and Data • The internet on things : A lot of devices and parts will be connected to internet • The number of smartphone and tablet is increasing rapidly • Wearable devices will be available with reasonable price soon • Model, Model and Model • Machine Learning, Statistical models are available as a service with reasonable costs through internet 2

  4. 4. How can we consume data ? • Although a lot of data is available for data analysis, It is not obvious that how we can analyze it in order to make better business decisions • At the result of that, most of data may not be analyzed for decision making 4
  5. 5. Data savvy managers are needed • Someone in the company should take an initiative to lead the project for big data analytics all over the company • Someone should take actions to obtain better business decisions based on the results of data analysis 5
  6. 6. Data scientist vs Data savvy manager 6 Data savvy manager Data scientist Data knowledge on data in the business data cleaning make it structured Statistical Models ensure models are relevant to make business decisions develop models validate models Output from analysis ensure the results are relevant to make business decisions ensure calculation is accurate
  7. 7. How to be data savvy managers • No need to pay a lot of money to be the managers • A lot of useful information are available through internet for free • Statistical tools and data visualization tools (such as R) are also available free or with reasonable costs • A lot of universities provide their courses about data analysis through internet for free (called "MOOCs") 7
  8. 8. R language and RStudio 8 It is free !
  9. 9. Key three things to be data savvy mangers • Data • Model • Output from analysis 9
  10. 10. First : Data • Starting point of data analysis • Business managers should know what kind of data are available for their businesses • Make the list of available data • Discuss data which are available with data scientists 10
  11. 11. Second : model • Data savvy managers should know what kind of models exist for data analysis • Statistical model (regression, time series analysis, optimization, etc.) • Machine learning (neural network, decision tree, etc.) • Genetic Programming 11
  12. 12. No need to develop models by yourself Just discuss it with data scientists ML<-function(a){ ! x=matrix(c(1,1,1,1,2,3),3,2) y=matrix(c(5, 7, 9),3,1) t=matrix(1,2,1) m=length(y) h=x%*%t j=1/(2*m)*(t(h-y)%*%(h-y)) ! 12 for (i in seq(1,1000)){ h=x%*%t tnew=t-a/m*t(x)%*%(h-y) hnew=x%*%tnew jnew=1/(2*m)*(t(hnew-y)%*%(hnew-y)) if (abs(jnew-j)<=10^(-8)) break t=tnew j=jnew end }} An example of Liner regression model by R
  13. 13. Third : Output • Outputs from data analysis are critically important • Outputs are numerical numbers (price, population, revenue, etc.) • Outputs are probability of events (explain later) 13
  14. 14. To make better business decisions • Marketing strategy (target, product, price, etc.) • Resource and cost allocations • Risk management (credit, market, liquidity, etc.) 14
  15. 15. Predictive analytics • Logistic regression model is used to calculate probability of events • Output means probability of events (buy products, come to shops, cure diseases, be in default, etc) • Logistic regression model generates numbers between 0 and 1 as the result of calculations • These outputs are considered as probability of occurring events 15
