Machine Learning algorithms can help computers play chess, perform surgeries, and get smarter and more personal. K-Means & logistic regression are two widely used Machine learning algorithms which we are going to discuss in this video. Logistic Regression is used to estimate discrete values (usually binary values like 0/1) from a set of independent variables. It helps to predict the probability of an event by fitting data to a logit function. It is also called logit regression. K-means clustering is an unsupervised learning algorithm. In this case, you don't have labeled data unlike in supervised learning. You have a set of data that you want to group into and you want to put them into clusters, which means objects that are similar in nature and similar in characteristics need to be put together. This is what k-means clustering is all about. Now, let us get started and understand K-Means clustering & logistic regression in detail.

Levelwise PageRank with Loop-Based Dead End Handling Strategy : SHORT REPORT ...Subhajit Sahu
Abstract — Levelwise PageRank is an alternative method of PageRank computation which decomposes the input graph into a directed acyclic block-graph of strongly connected components, and processes them in topological order, one level at a time. This enables calculation for ranks in a distributed fashion without per-iteration communication, unlike the standard method where all vertices are processed in each iteration. It however comes with a precondition of the absence of dead ends in the input graph. Here, the native non-distributed performance of Levelwise PageRank was compared against Monolithic PageRank on a CPU as well as a GPU. To ensure a fair comparison, Monolithic PageRank was also performed on a graph where vertices were split by components. Results indicate that Levelwise PageRank is about as fast as Monolithic PageRank on the CPU, but quite a bit slower on the GPU. Slowdown on the GPU is likely caused by a large submission of small workloads, and expected to be non-issue when the computation is performed on massive graphs.

11. METHODOLOGY
• In the Data Understanding stage, data scientists try to understand more about the data collected before.
We have to check the type of each data and to learn more about the attributes and their names.
• In the Data Preparation stage, data scientists prepare data for modeling, which is one of the most crucial
steps because the model has to be clean and without errors.
• In the Modeling stage, the data scientist has the chance to understand if his work is ready to go or if it
needs review. Modeling focuses on developing models that are either descriptive or predictive, and these
models are based on the analytic approach that was taken statistically or through machine learning.
12. METHODOLOGY
• In the Model Evaluation stage, data scientists can evaluate the model in two ways: Hold-Out
and Cross-Validation. In the Hold-Out method, the dataset is divided into three subsets:
a training set as we said in the modeling stage; a validation set that is a subset used to
assess the performance of the model built in the training phase; a test set is a subset to
evaluate the likely future performance of a model.
• The Deployment stage depends on the purpose of the model, and it may be rolled out to a
limited group of users or in a test environment.
• The Feedback stage is usually made the most from the customer.
13. METHODOLOGY
Common Algorithms :
1 .Linear Regression
A statistical method used to model the relationship between a dependent variable and one or
more independent variables.
We can use simple linear regression when you want to know:
1. How strong the relationship is between two variables (e.g., the relationship between rainfall
and soil erosion).
2. The value of the dependent variable at a certain value of the independent variable (e.g., the
amount of soil erosion at a certain level of rainfall).
14. METHODOLOGY
Simple linear regression formula :
y is the predicted value of the dependent
variable (y) for any given value of the
independent variable (x).
B0 is the intercept, the predicted value
of y when the x is 0.
B1 is the regression coefficient – how much
we expect y to change as x increases.
x is the independent variable ( the variable
we expect is influencing y).
e is the error of the estimate, or how much
variation there is in our estimate of the
regression coefficient.
15. METHODOLOGY
2. Decision Tree :
• A decision tree is a machine learning
algorithm that uses a tree-like model of
decisions and their possible consequences
to predict outcomes. It is a supervised
learning algorithm that can be used for both
classification and regression tasks.
• The decision tree algorithm works by
recursively splitting the data into subsets
based on the values of the input features.
The goal is to create a tree that predicts the
target variable with high accuracy.
