6. What is Machine?

7. What is Machine Learning?
- Capable to analyse data
- Ability to learn itself
- Take decision

8. Supervised Machine Learning
-pre define data
-train data
-understanding the data
-take decision
Y = f(X)
input variables = (x)
output variable = (Y)
Supervised Learning can be divided into 2 categories
1.Classification
2.Regression

9. Classification: A classification problem is when the output variable is a
category, such as “red” or “blue” or “disease” and “no disease”.
Example: Spam Detection, Churn Prediction, Sentiment Analysis, Dog
Breed Detection.
Regression: A regression problem is when the output variable is a real
value, such as “dollars” or “weight”.
Example: House Price Prediction, Stock Price Prediction, Height-
Weight Prediction.

10. Unsupervised Machine Learning
-only have input data (X)
-unlabeled data
-no corresponding output variables
Unsupervised learning problems can be further grouped into clustering and
association problems.
Clustering: A clustering problem is where you want to discover the inherent
groupings in the data, such as grouping customers by purchasing behavior.

11. Association: An association rule learning problem is where you want
to discover rules that describe large portions of your data, such as
people that buy X also tend to buy Y.
Example: Given many baskets (could be text documents, actual
supermarket baskets, other semi-structured objects) find which items
inside a basket predict another item in the basket.

12. Semi Supervised Machine Learning
=Supervised + Unsupervised

13. Reinforcement Machine Learning
-interacts with its environment
-produce actions
-trail
-discovers errors
-automatically determine
the ideal behavior
- maximize its performance

14. Uses Of Machine Learning
• Image recognition
• Voice recognition
• Predictions
• Spam and Malware
• Search engine, Google Allo, Map, Facebook, Gmail, Youtube,
Twitter etc.
• Fraud Detection

15. Difference Between CSE Program &
Machine Learning Program
CSE Program
-make program
-give input
-known output
ML Program
-give data
-data access or analyse
-known/unknown output
-making program itself
-take decision

16. Future Of Machine Learning
Some predictions about Machine Learning based on current technology
trends and ML’s systematic progression toward maturity:
• ML will be an integral part of all AI systems, large or small.
• Cloud-based service known as Machine Learning-as-a-Service.
• Connected AI systems will enable ML algorithms to “continuously
learn,” based on newly emerging information on the internet.
• A big rush among hardware vendors to enhance CPU power to
accommodate ML data processing.
• Hardware vendors will be pushed to redesign their machines to do
justice to the powers of ML.
• Machine Learning will help machines to make better sense of
context and meaning of data.
