Online Learning
This kind of learning is the opposite of batch learning. I mean that, here,
 the
system can learn incrementally by providing the system with 
all the available
data as instances (groups or individually), and then the system can learn on the
fly.
You can use this type of system for problems that require the continuous flow of
data, which also needs to adapt quickly to any changes. Also, you can use this
type of system to work with very large data sets,
You should know how fast your system can adapt to any changes in the data’s
“learning rate.” If the speed is high, means that the system will learn quite,
quickly, but it also will forget old data quickly.


 
Instance based learning
This is the simplest type of learning that you should learn by heart. By using
this type of learning in our email program, it will flag all of the emails that were
flagged by users.
.


Model-based learning
There is another type of learning in which learning from examples allows
construction to make predictions


Bad and Insufficient Quantity of Training Data
Machine-learning systems are not like children, who can distinguish apples and
oranges in all sorts of colors and shapes, but they require lot of data to work
effectively, whether you're working with very simple programs and problems, or
complex applications like image processing and speech recognition. Here is an
example of the unreasonable effectiveness of data, showing the MS project,
which includes simple data and the complex problem of NLP.
