Observability for Data Pipelines With OpenLineageDatabricks
Data is increasingly becoming core to many products. Whether to provide recommendations for users, getting insights on how they use the product, or using machine learning to improve the experience. This creates a critical need for reliable data operations and understanding how data is flowing through our systems. Data pipelines must be auditable, reliable, and run on time. This proves particularly difficult in a constantly changing, fast-paced environment.
Collecting this lineage metadata as data pipelines are running provides an understanding of dependencies between many teams consuming and producing data and how constant changes impact them. It is the underlying foundation that enables the many use cases related to data operations. The OpenLineage project is an API standardizing this metadata across the ecosystem, reducing complexity and duplicate work in collecting lineage information. It enables many projects, consumers of lineage in the ecosystem whether they focus on operations, governance or security.
Marquez is an open source project part of the LF AI & Data foundation which instruments data pipelines to collect lineage and metadata and enable those use cases. It implements the OpenLineage API and provides context by making visible dependencies across organizations and technologies as they change over time.
Learn to Use Databricks for the Full ML LifecycleDatabricks
Machine learning development brings many new complexities beyond the traditional software development lifecycle. Unlike traditional software development, ML developers want to try multiple algorithms, tools and parameters to get the best results, and they need to track this information to reproduce work. In addition, developers need to use many distinct systems to productionize models. In this talk, learn how to operationalize ML across the full lifecycle with Databricks Machine Learning.

Machine learning lets you make better business decisions by uncovering patterns in your consumer behavior data that is hard for the human eye to spot. You can also use it to automate routine, expensive human tasks that were previously not doable by computers. In the business to business space (B2B), if your competitors can make wiser business decisions based on data and automate more business operations but you still base your decisions on guesswork and lack automation, you will lose out on business productivity. In this introduction to machine learning tech talk, you will learn how to use machine learning even if you do not have deep technical expertise on this technology.
Topics covered:
1.What is machine learning
2.What is a typical ML application architecture
3.How to start ML development with free resource links
4.Key decision factors in ML technology selection depending on use case scenarios
The Power of Auto ML and How Does it WorkIvo Andreev
Automated ML is an approach to minimize the need of data science effort by enabling domain experts to build ML models without having deep knowledge of algorithms, mathematics or programming skills. The mechanism works by allowing end-users to simply provide data and the system automatically does the rest by determining approach to perform particular ML task. At first this may sound discouraging to those aiming to the “sexiest job of the 21st century” - the data scientists. However, Auto ML should be considered as democratization of ML, rather that automatic data science.
In this session we will talk about how Auto ML works, how is it implemented by Microsoft and how it could improve the productivity of even professional data scientists.

3. ABOUT RAPID
MINER
• Integrated Environment for data preparation,machine learning,deep learning,text
mining,predictive analytics.
• Wide range of Applications
• Supports All steps of Datamining
• Template-base work
4. MARKET OF RAPID
MINERRapidMiner received one of the strongest satisfaction ratings in the
2011 Rexer Analytics Data Miner Survey.
RapidMiner has received over 3 million total downloads and has over
250,000 users including eBay, Intel,PepsiCo and Kraft Foods as
paying customers.
RapidMiner claims to be the market leader in the software for
predictive data analytics services against competitors such as
Revolution Analytics, SAS, Predixion Software, SQL Server, StatSoft and
IBM.
6. WHY
RAPIDMINER
vices
• GUI
• Data from file, database, web, and cloud ser
• GUI or batch processing
• Integrates with in-house databases
• Data filtering, merging, joining and aggregating
• Build, train and validate predictive models
• Runs on every major platform and operating system
….. And Much More
7. • The term attribute is RapidMiner for "column."
• In machine learning, each row of a data set is an example
for a specific situation and the attributes (columns) are the
properties that describe the situation.
• It is sometimes also known as target or class or predicted
label.
8. • Join, Aggregate, Filter, Sort, Generate Attributes, and
Select Attributes.
• The role of an attribute describes how the column is
used by machine learning operators.
• Attributes without any role (also called "regular"
attributes) are used as input for training while id
attributes are usually ignored by modeling algorithms
because they are only used as unique identifiers of
observations of data.
Attributes
9.

11. There are two general groups of data handling:
• Blending
• cleansing.
Blending is about transforming a data set from one state to
another or combining multiple data sets.
Cleansing is about improving the data so that modeling will
deliver better results.
14. Data Cleansing
• Identify unusual cases and remove them from the data
set.
• In some cases ,outliers are the most interesting cases,
but in most cases outliers are simply the result of an
incorrect measurement and should be removed from the
data set.
• A distance-based outlier detection algorithm is used
,which calculates the Euclidean distance between the
data points and marks those points which are farthest
away from other data points as outliers. The Euclidean
distance uses the distances between two data points for
each individual attribute.
• It creates a new column named outlier with true as the
value for the outliers and false for all other examples.
15.
16.
17. Predictive Modeling
• Predictive Modeling is a set of machine learning
techniques which search for patterns in big data sets and
use those patterns to create predictions for new
situations.
• Those predictions can be categorical (this is called
classification learning) or numerical (regression learning).
• In this, we need training data with known labels as input
for this kind of machine learning method. So this type of
method supervised learning.
18.
19.
20.
21. Scoring
• Using a model to generate predictions for new data
points is called Scoring.
• Here,the Naïve Bayes method is used to predict the
"Survived" class (yes / no) of each passenger and find
their respective confidences
• Apply Model operator is used to create predictions for
a new, unlabeled data set.
22.
23. Split labeled data into two partitions.
• Split Data takes an example set and divides it into the
partitions we have defined.
• In this case, we will get two partitions with 70% of the
data in one and 30% of the data in the other.
24.
25. Cross Validation
• Cross Validation to make sure each data point is used
as often for training as it is for testing which avoids this
problem.
• Cross validation divides the example set into equal parts
and rotates through all parts, always using one for
testing and all others for training the model. At the end,
the average of all testing accuracies is delivered as
result.
• By default this splits the data into 10 different parts, so
we call this a 10-fold cross validation.
• change the number of folds in the Parameters panel.
