3. Pig
Apache developed Pig, which:
• Is an abstraction over MapReduce.
• Is an execution framework for parallel processing.
• Reduces the complexities of writing a MapReduce program.
• Is a high-level dataflow language. Dataflow language means that a
Pig.
• operation node takes the inputs and generates the output for the
next node.
4. Applications of Pig are:
• Analyzing large datasets.
• Executing tasks involving adhoc processing.
• Processing large data sources such as web logs and streaming online
data.
• Data processing for search platforms. Pig processes different types of
data.
• Processing time sensitive data loads.
5. Introduction to Artificial Intelligence
⚫Artificial Intelligence (AI) refers to the science and engineering of making
computers perform tasks, which normally require human intelligence. For
example, tasks such as predicting future results, visual perception, speech
recognition, decision making and natural language processing.
⚫Two concepts in AI, 'machine learning' and 'deep learning' provide
powerful tools for advanced analytics and predictions.
6. ESTIMATING THE RELATIONSHIPS
⚫ A relationship between two or more quantitative dependent variables with
respect to an independent variable can be well-depicted using graph, scatter
plot or chart with data points, shown in distinct shapes. Conventionally,
independent variables are on the x-axis, whereas the dependent variables on the
y-axis in a graph. A line graph uses a line on an x-y axis to plot a continuous
function.
7. Estimating Relationship
Estimating the relationships means finding a mathematical expression, which gives
the value of the variable according to its relationship with other variables. For
example, assume Ym = sales of a car model m in xth year of the start of
manufacturing that model.
