  Unit 3: Regression   Linear Regression: Prediction using Linear Regression, Gradient Descent, Linear Regression with one Variable, Linear Regression with Multiple Variables, Polynomial Regression, Feature Scaling/Selection. Logistic Regression: Classification using Logistic Regression, Logistic Regression vs. Linear Regression, Logistic Regression with one Variable and with Multiple Variables.   Linear Regression: What is Regression?             Regression is the mathematical method that used to find the value of an unknown variable with the help of another variable. For example X+5=Y , where Y is in between 10   then the value of X be 5 X 5 Y 10   What is Linear Regression?             Linear Regression is also the statistical method that used to find the value of an unknown variable wi...

 Unit 4 - Part I - Memory Management Physical and Virtual Address Space Physical Address  identifies a physical location of required data in a memory. The user never directly deals with the physical address but can access by its corresponding logical address. The user program generates the logical address and thinks that the program is running in this logical address but the program needs physical memory for its execution, therefore, the logical address must be mapped to the physical address by MMU before they are used. The term Physical Address Space is used for all physical addresses corresponding to the logical addresses in a Logical address space. Logical Address  is generated by CPU while a program is running. The logical address is virtual address as it does not exist physically, therefore, it is also known as Virtual Address. This address is used as a reference to access the physical memory location by CPU. The term Logical Address Space is used for the set of ...
