2. Automates repetitive triage and error steps used in machine learning model generation
Accelerates the process of producing better models
No detailed understanding of each algorithm is required
May be simplified via drag-and-drop environment or in code for data scientists
AutoML can provide a final model or a starting point from one can fine-tunes the model
What is AutoML?
4. Types of Machine Learning
Supervised Learning
Predict future outcomes with the help of training
data provided by human experts
Semi-Supervised Learning
Discover patterns within raw data and make
predictions, which are then reviewed by human
experts, who provide feedback which is used to
improve the model accuracy
Unsupervised Learning
Find patterns without any external input other
than the raw data
Reinforcement Learning
Take decisions based on past rewards for this type
of action
5. ML Project Workflow
Set the business objectives
Gather compare and
clean data
Identify and extract features
(important columns) from imported data
This helps us identify the efficiency of the
algorithm
Take the input data which is also called the training data
and apply the algorithm to it
In order for the algorithm to function efficiently, it is
important to pick the right value for hyper parameters
(input parameters to the algorithm)
Once the training data in the
algorithm are combined we
get a model

6. ML is here to stay and is just getting started
The last 4 years of advances in this field dwarfs
the previous 50 years of growth
We need to identify use cases to make the
business better
Conclusions then
Modelling and ML infrastructure will
become standard aka AutoML
Getting the right data to train matters
to have a successful outcome
Models will get better with sparse data
Most enterprise applications are already
using embedded ML
8. With more affordable compute
power, AutoML becomes more
accessible.
Particularly for cloud-based tools,
as compute power can be scaled
up as needed
The growth in availability of open
source and commercial AutoML
libraries has expanded the scope of
what is easily handled by AutoML
Solution vendors and investing in
AutoML because of the benefits to
data scientists and their organizations
Why is AutoML so popular now?
9. Does not replace data scientists but
rather expediate their capabilities
Does AutoML remove the need for Data Scientists?
At the advent of the assembly line in manufacturing,
many tedious processes were automated.
This enabled workers to put their time and energy into
bigger issues, from quality of product to improving design
and manufacturing processes.
AutoML gives similar power to data scientists,
delivering more time to engineer predictive
features, develop data acquisition strategies,
improve the data transformation pipelines, and
more.
