Modules 6-10 Flashcards
What is Artificial Intelligence (AI) and Machine Learning (ML)?
Finding PATTERNS in data –> then, using them to make predictions
What are the two kind of data?
Structured and Unstructured
What is included in Structural Data?
table w/ rows/columns
What is included in Unstructured Data?
images, sound, speech, text
Which type of data is most commonly used?
Structured
What Is necessary to develop an dAI/ML app?
inputs and outputs
T/F
You do not need existing data on both inputs and output
FALSE
You MUST have EXISTING data on both INPUTS and OUTPUT
Example of input/output data to find patterns
Input –> ECG recording
Output –> Atrial Fibrilation
What is the process of….?
define the pattern
get the data
prepare the data
discover and visualize
train ML models
evaluate the models
select best one and fine tune
launch, monitor, maintain
Why do project not succeed?
data quality
data labeling
model accuracy/confidence
What percentage of projects fail?
85%
What percentage of projects stall?
96%
Examples of Structured data platforms
Microsoft azure machine learning studio
SAS enterprise miner (or viya)
python sci-kit learn
Examples of unstructured data platforms
python - Tensorflow, Keras code from scratch
Volume
The amount of data
- quantity of generated and stored data
variety
variety of forms of data
- the type and nature of the data
velocity
the speed new data is generated and moves around
- the speed at which the data is generated and processed to meet the demands and challenges that lie in the path of growth and development.
veracity
the trustworthiness of the data
- the extended definition for big data, which refers to the data quality and the data value
What would be included in big data for healthcare?
- electronic health record
- insurance claims
- data collected from smartphone applications, wearable devices, social media
- population genomics data
What characteristics can big data be described by?
The four V
-volume

What are structured and unstructured data in EHR?
- Structured is the defined units and values
- Unstructured are images and notes
Understand database, table, primary key and foreign key
- PRIMARY KEY: unique identifier
- FOREIGN KEY: the common factor between two tables
- DATABASE:
