Apache Spark Introduction and Resilient Distributed Dataset basics and deep diveSachin Aggarwal
We will give a detailed introduction to Apache Spark and why and how Spark can change the analytics world. Apache Spark's memory abstraction is RDD (Resilient Distributed DataSet). One of the key reason why Apache Spark is so different is because of the introduction of RDD. You cannot do anything in Apache Spark without knowing about RDDs. We will give a high level introduction to RDD and in the second half we will have a deep dive into RDDs.

Apache Spark for Library Developers with William Benton and Erik ErlandsonDatabricks
As a developer, data engineer, or data scientist, you’ve seen how Apache Spark is expressive enough to let you solve problems elegantly and efficient enough to let you scale out to handle more data. However, if you’re solving the same problems again and again, you probably want to capture and distribute your solutions so that you can focus on new problems and so other people can reuse and remix them: you want to develop a library that extends Spark.
You faced a learning curve when you first started using Spark, and you’ll face a different learning curve as you start to develop reusable abstractions atop Spark. In this talk, two experienced Spark library developers will give you the background and context you’ll need to turn your code into a library that you can share with the world. We’ll cover: Issues to consider when developing parallel algorithms with Spark, Designing generic, robust functions that operate on data frames and datasets, Extending data frames with user-defined functions (UDFs) and user-defined aggregates (UDAFs), Best practices around caching and broadcasting, and why these are especially important for library developers, Integrating with ML pipelines, Exposing key functionality in both Python and Scala, and How to test, build, and publish your library for the community.
We’ll back up our advice with concrete examples from real packages built atop Spark. You’ll leave this talk informed and inspired to take your Spark proficiency to the next level and develop and publish an awesome library of your own.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

The Art of the Pitch: WordPress Relationships and SalesLaura Byrne
Clients don’t know what they don’t know. What web solutions are right for them? How does WordPress come into the picture? How do you make sure you understand scope and timeline? What do you do if sometime changes?
All these questions and more will be explored as we talk about matching clients’ needs with what your agency offers without pulling teeth or pulling your hair out. Practical tips, and strategies for successful relationship building that leads to closing the deal.

and
Point SPARK_HOME to your Spark
installation
and
Launch bin/sparkling-shell
14. What is Sparkling Shell?

19. Load Data #1
Load weather data into RDD
val weatherDataFile =
“examples/smalldata/weather.csv"
val wrawdata = sc.textFile(weatherDataFile,3)
.cache()
val weatherTable = wrawdata
.map(_.split(“,"))
.map(row => WeatherParse(row))
.filter(!_.isWrongRow())
Regular Spark API
Ad-hoc Parser
20. Weather Data
case class Weather( val Year : Option[Int],
val Month : Option[Int],
val Day : Option[Int],
val TmaxF : Option[Int], // Max temperatur in F
val TminF : Option[Int], // Min temperatur in F
val TmeanF : Option[Float], // Mean temperatur in F
val PrcpIn : Option[Float], // Precipitation (inches)
val SnowIn : Option[Float], // Snow (inches)
val CDD : Option[Float], // Cooling Degree Day
val HDD : Option[Float], // Heating Degree Day
val GDD : Option[Float]) // Growing Degree Day
Simple POJO to hold one row of weather data
21. Load Data #2
Load flights data into H2O frame
import java.io.File
val dataFile =
“examples/smalldata/allyears2k_headers.csv.gz"
val airlinesData = new DataFrame(new File(dataFile))
22. Where is the data?
Go to http://localhost:54321/steam/
index.html
23. Use Spark API for Data
Filtering
Create a cheap wrapper
around H2O DataFrame
// Create RDD wrapper around DataFrame
val airlinesTable : RDD[Airlines]
= toRDD[Airlines](airlinesData)
// And use Spark RDD API directly
val flightsToORD = airlinesTable
.filter( f => f.Dest == Some(“ORD") )
Regular Spark
RDD call
24. Use Spark SQL to Data
Join
import org.apache.spark.sql.SQLContext
// We need to create SQL context
val sqlContext = new SQLContext(sc)
import sqlContext._
flightsToORD.registerTempTable("FlightsToORD")
weatherTable.registerTempTable("WeatherORD")
25. Join Data based on Flight
Date
val bigTable = sql(
"""SELECT
| f.Year,f.Month,f.DayofMonth,
| f.CRSDepTime,f.CRSArrTime,f.CRSElapsedTime,
| f.UniqueCarrier,f.FlightNum,f.TailNum,
| f.Origin,f.Distance,
| w.TmaxF,w.TminF,w.TmeanF,
| w.PrcpIn,w.SnowIn,w.CDD,w.HDD,w.GDD,
| f.ArrDelay
| FROM FlightsToORD f
| JOIN WeatherORD w
| ON f.Year=w.Year AND f.Month=w.Month
| AND f.DayofMonth=w.Day""".stripMargin)
26. Launch H2O Algorithms
import hex.deeplearning._
import hex.deeplearning.DeepLearningModel
.DeepLearningParameter s
// Setup deep learning parameters
val dlParams = new DeepLearningParameters()
dlParams._train = bigTable
dlParams._response_column = 'ArrDelay
dlParams._epochs = 100
// Create a new model builder
val dl = new DeepLearning(dlParams)
val dlModel = dl.trainModel.get
Result of
SQL query
Blocking call
27. Make a prediction
// Use model to score data
val prediction = dlModel.score(result)(‘predict)
// Collect predicted values via RDD API
val predictionValues = toRDD[DoubleHolder](prediction)
.collect
.map ( _.result.getOrElse("NaN") )
28. Generate Residuals Plot
# Import H2O library and initialize H2O client
library(h2o)
h = h2o.init()
# Fetch prediction and actual data, use remembered keys
pred = h2o.getFrame(h, "dframe_b5f449d0c04ee75fda1b9bc865b14a69")
act = h2o.getFrame (h, "frame_rdd_14_b429e8b43d2d8c02899ccb61b72c4e57")
# Select right columns
predDelay = pred$predict
actDelay = act$ArrDelay
# Make sure that number of rows is same
nrow(actDelay) == nrow(predDelay)
# Compute residuals
residuals = predDelay - actDelay
# Plot residuals
compare = cbind(
as.data.frame(actDelay$ArrDelay),
as.data.frame(residuals$predict))
plot( compare[,1:2] )
