Hypothesis function and testing in Machine Learning

By Kajal Vishwakarma -

 Hypothesis function and testing:-

Hypothesis testing is a statistical method that is used in making statistical decision using experimental data. Hypothesis Testing is basically an assumption that we make about the population parameter.

Ex : you say avg student in class is 40 or a boy is taller than girls.

All those example we assume need some statistic way to prove those. we need some mathematical conclusion what ever we are assuming is true.

Hypothesis testing is an essential procedure in statistics. A hypothesis test evaluates two mutually exclusive statements about a population to determine which statement is best supported by the sample data. When we say that a finding is statistically significant, it's thanks to a hypothesis test. The process of hypothesis testing is to draw inferences or some conclusion about the overall population or data by conducting some statistical tests on a For drawing some inferences, we have to make some assumptions that lead to two terms that are used in the hypothesis testing.

  • Null hypothesis:- It is regarding the assumption that there is no anomaly pattern or believing according to the assumption made.
  • Alternate hypothesis:- Contrary to the null hypothesis, it shows that observation is the result of real effect.
Some of widely used hypothesis testing types:-
  1. T Test {Student T test}
  2. Z Test
  3. ANOVA Test
  4. Chi-Square Test

Protocol verification using finite state machine model in computer network

By Kajal Vishwakarma -
Protocol Verification Using Finite State Machine Model:- The finite state machine is a mainly used in several protocol models with this technique, every protocol machine is always in a particular state at every time instant. Variables, including the program counter. From every state, there are zero or more possible transition to other states. When some event happens, transition take place. In case of a protocol machine, a transition might take place if a frame is transmitted, if a frame arrives, if a timer expires, if an interrupt takes place, etc. One particular state is designated as the initial state. This state corresponds to the description of the system when it starts running, or at some convenient starting place shortly thereafter. From the initial state, some, perhaps all, of the other states may be approached by a sequence of transition. this technique is called reachability analysis. This analysis can be helpful in determining whether a protocol is correct. All processes are

Scope and Limitation of Machine Learning

By Kajal Vishwakarma -
 Scope :- Increase in Data Generation:- Due to excessive production of data, need a method that can be used to structure, analyze and draw useful insight from data. This is where machine learning comes in. It uses data to solve problems and find solution the most complex tasks faced by organizations. Improve Decision Making :- By making use of Various algorithms, Machine Learning can be used to make better business decisions. For example, Machine Learning is used to forecast sales, predict downfalls in the stock market, identify risks and anomalies, etc. Uncover patterns & trends in data:- Finding hidden patterns and extracting key insight from data is the most essential part of machine learning. by building predictive models and using statistical techniques, machine learning allows you to dig beneath the surface and explore the data at a minute scale. Understanding data and extracting patterns manually will take days, whereas machine learning algorithms can perform such computati
