What’s the difference between inductive, deductive, and abductive learning? Inductive learning describes smart algorithms that learn from a set of instances to draw conclusions. In statistical ML, k-nearest neighbor and support vector machine are good examples of inductive learning. There are three literals in (top-down) inductive learning: Arithmetic literals Equality and inequality Predicates In deductive … Read more
When break is used inside two nested for loops, control comes out of which loop, the inner or the outer for loop? (I.e. does it break from all the present loops?) It breaks from the inner loop only. What is Marshaling? Marshaling is the process of transforming types in the managed and unmanaged code. Which … Read more

These objects are parsed by the JSP engine and inserted into the generated servlet. The implicit objects re listed below: request :It represents the request made by the client.

What is the difference between the heap table and the temporary table? Heap tables: Heap tables are found in memory that is used for high-speed storage temporarily. They do not allow BLOB or TEXT fields. Heap tables do not support AUTO_INCREMENT. Indexes should be NOT NULL. Temporary tables: The temporary tables are used to keep … Read more
Is ARIMA model a good fit for every time series problem? No, ARIMA model is not suitable for every type of time series problem. There are situations where ARMA model and others also come in handy. ARIMA is best when different standard temporal structures require to be captured for time series data. What is inductive … Read more
Can a double value be cast to a byte Yes, a double value can be cast to a byte. Is the ternary operator written x : y ? z or x ? y : z It is written x ? y : z. Can an abstract class be final An abstract class may not be declared as final. What is the difference … Read more

Data analysts also need strong writing skills, so they can present the results of their analysis to management and stakeholders … Read more
What is a depth-first search algorithm? Depth-first search (DFS) is based on LIFO (last-in, first-out). A recursion is implemented with LIFO stack data structure. Thus, the nodes are in a different order than in BFS. The path is stored in each iteration from root to leaf nodes in a linear fashion with space requirement. How … Read more
What are the three levels of data abstraction? Following are three levels of data abstraction: Physical level: It is the lowest level of abstraction. It describes how data are stored. Logical level: It is the next higher level of abstraction. It describes what data are stored in the database and what the relationship among those data is. … Read more
