FUTURE READY HR: STRATEGIES FOR POSITIVE WORKPLACE CULTUREHuman Capital Media
Major fluctuations are underway, including EEOC investigations, FLSA developments and uncertainty surrounding the ACA. To successfully navigate this new world of regulatory compliance and uncertainty — while ensuring that your organization is prepared to nurture and engage your workforce — you need accurate and immediate access to people data.
Organizations today have access to more information than ever before, but are you using that data to ease compliance requirements, and more importantly, to serve your employees better? Just having the data isn’t enough. Many organizations are drowning in this sea of unorganized information, unable to leverage its full potential. Consider how you can better leverage this mass of information to better engage and nurture employees.
Large or small, HR departments that are bogged down by manual processes, administrative tasks and compliance paperwork don’t have the data or the planning tools needed for strategic influence. So they’re unable to fully and effectively advocate for the employee experience during corporate strategy and decision-making. Join us for this 60-minute program where our panelists will discuss the future-ready HR department. Starting with tips to manage the current regulatory landscape around human resources, our panelists will discuss the importance of data access and visibility to ensure compliance with constantly evolving requirements, and identify human capital management tools and strategies that can help your organization move closer to a data-driven HR function.
Webinar participants will learn:
Recent and upcoming developments in laws and regulations surrounding human resources.
The importance of reporting and data collection for maintaining compliance and making data-driven people decisions.
Strategies for effective collection and reporting of human resources data to use it properly to streamline compliance efforts and drive employee engagement.
Big Data Analytics for Healthcare Decision Support- Operational and ClinicalAdrish Sannyasi
Splunk’s data analytics platform could be utilized to solve many high impact business problems in healthcare delivery systems to reduce cost, improve patient outcome and safety, and enhance care coordination experience. Analyze observed behavior from healthcare event data and metadata to discover patterns, monitor compliance, and optimize the workflow. Furthermore 80% of healthcare data is unstructured (clinical free text and documentation), or semi-structured and many new data sources are such as tele health, mobile health, sensors, and devices are getting integrated in many healthcare systems specifically in the area of chronic disease management. So, one need analytics software that can harvest, interpret, enrich, normalize, and model diverse structured and unstructured data and analytics approaches that embrace the “data turmoil” by relying less on standardized data items and more on the capability to process data in any format.
Assessment of Constraints to Data Use is a rapid assessment tool designed to identify barriers and constraints that inhibit effective practices in data use.

Levelwise PageRank with Loop-Based Dead End Handling Strategy : SHORT REPORT ...Subhajit Sahu
Abstract — Levelwise PageRank is an alternative method of PageRank computation which decomposes the input graph into a directed acyclic block-graph of strongly connected components, and processes them in topological order, one level at a time. This enables calculation for ranks in a distributed fashion without per-iteration communication, unlike the standard method where all vertices are processed in each iteration. It however comes with a precondition of the absence of dead ends in the input graph. Here, the native non-distributed performance of Levelwise PageRank was compared against Monolithic PageRank on a CPU as well as a GPU. To ensure a fair comparison, Monolithic PageRank was also performed on a graph where vertices were split by components. Results indicate that Levelwise PageRank is about as fast as Monolithic PageRank on the CPU, but quite a bit slower on the GPU. Slowdown on the GPU is likely caused by a large submission of small workloads, and expected to be non-issue when the computation is performed on massive graphs.
Enhanced Enterprise Intelligence with your personal AI Data Copilot.pdfGetInData
Recently we have observed the rise of open-source Large Language Models (LLMs) that are community-driven or developed by the AI market leaders, such as Meta (Llama3), Databricks (DBRX) and Snowflake (Arctic). On the other hand, there is a growth in interest in specialized, carefully fine-tuned yet relatively small models that can efficiently assist programmers in day-to-day tasks. Finally, Retrieval-Augmented Generation (RAG) architectures have gained a lot of traction as the preferred approach for LLMs context and prompt augmentation for building conversational SQL data copilots, code copilots and chatbots.
In this presentation, we will show how we built upon these three concepts a robust Data Copilot that can help to democratize access to company data assets and boost performance of everyone working with data platforms.
Why do we need yet another (open-source ) Copilot?
How can we build one?

Adjusting OpenMP PageRank : SHORT REPORT / NOTESSubhajit Sahu
For massive graphs that fit in RAM, but not in GPU memory, it is possible to take
advantage of a shared memory system with multiple CPUs, each with multiple cores, to
accelerate pagerank computation. If the NUMA architecture of the system is properly taken
into account with good vertex partitioning, the speedup can be significant. To take steps in
this direction, experiments are conducted to implement pagerank in OpenMP using two
different approaches, uniform and hybrid. The uniform approach runs all primitives required
for pagerank in OpenMP mode (with multiple threads). On the other hand, the hybrid
approach runs certain primitives in sequential mode (i.e., sumAt, multiply).

Optimizing Data Synthesis and Visualization in Real-Time Decision-Making
1. Optimizing Data Synthesis
and Visualization in Real-
Time Decision-Making
Kim Bender, AMS Summer Meeting
August 2014
2. “As weather forecaster you will be asked to make decisions
in situations where you will be under tight time constraints
and face uncertainty, you will have huge amounts of data
available, some of it contradictory and most of it not really
of significance to you, and you will be constantly looking for
the correct data, which will not normally be at your disposal
(Gaia & Fontannaz, 2006, p.17)”

3. Data Synthesis and Visualization in Real-Time
Decision Making
• Forecasting and aviation operations are both technological environments
where data is increasingly being incorporated into operator workstations to
optimize accuracy and efficiency
○ Automation
○ Decision Support Tools
○ Systems
Confidential and Proprietary. Do Not Distribute. 3
• Issues and questions:
○ How do you ensure the right systems are incorporated?
○ How do you ensure effective presentation and synthesis of information?
○ What are the impacts of the system on the human operator, safety, and
operations?
• What predisposes these operations to these environments?
Operators are required to make real-time decisions
in dynamically changing, uncertain environments
4. Human Factors: Decision Making in Uncertainty
• Decisions Making in Uncertainty
○ Heuristics – intuitive processes based on individual experience and perceptions
○ Objective data – structured and unstructured data but usually statistical in nature
• Heuristics mandatory in uncertain environments: Intuition and experience help
humans make quick effective decisions
○ Best human forecasters can consistently outperform objective methods-
Confidential and Proprietary. Do Not Distribute. 4
Heuristics!
○ Heuristics influenced by past experience and subjective considerations which can
be positive or negative
■ Positive – recognize similar situation or pattern and apply lessons learned when data is
uncertain
■ Negative – can introduce bias due to previous negative outcome or experience or it
can lead to missed event
□ Previous false alarm, forecasters tends to under forecast next event leading to a missed
alarm
□ Previous missed alarm, forecasters tend to over forecast after missed event
5. Human Factors: Decision Making in Uncertainty
• Inordinate amounts of objective data for real-time decision-making can be
problematic when not introduced effectively
• Operator must mine/culls/filter data to quickly synthesize
○ Multiple data sources can introduce more uncertainty
■ Contradictory output consistencies and forecasts
■ Individual data interpolation and integration/translation differences
○ Data overload – huge amounts of data
■ Contradictory data sources from disparate sources and systems
■ Most data not really of significance for task at hand
Confidential and Proprietary. Do Not Distribute. 5
○ Data Visualization
■ Scanning for correct/relevant data can be time consuming and problematic
■ Relevant data may not always be available or clear
■ Multiple systems introduce display and output inconsistencies
If data synthesis and visualization can be structured
carefully, could mitigate many significant issues
6. Evaluating Effective Data Presentation and
Visualization
• FAA tests proposed advanced aviation systems, procedures, and concepts
and/or performs experimental research to test proposed change
○ Subject Matter Expert (SME) Panels
Confidential and Proprietary. Do Not Distribute. 6
○ Simulation Research
○ Field Research
• Introduction of new data, information, and/or display in aviation environment
requires:
○ Operational Testing and Evaluation using SME’s
○ Measurement/evaluation of impacts of proposed technologies, displays, or
concepts on operations, safety, or human operator
○ SME evaluation of information display
7. Key Considerations for Data Synthesis and
Visualization
• Data introduction and visualization considerations
○ Data selection, design, display and is key to performance
○ Only present data that is meaningful and accurate - “too much” data will
eventually decrease performance by adding ineffective workload
• Implement a systematic approach to data presentation and visualization
○ SME and user evaluations during development and operational testing
○ Disciplined and systematic approach data presentation and visualization display
characteristics / system integration
■ Keep systems visually consistent – colors, presentation, warnings, etc.
■ System integration –data consistency

8. Key Considerations for Data Synthesis and
Visualization
• Experimental research to understand the effects of the system on human
performance and evaluate alternative approaches
• Understand human decision making and how operator
visualizes/interacts with large datasets in operational settings
○ Understand each operation – all different
○ Cognitive walkthroughs and walk-through like methods
• What data should be presented and how much to automate?
○ Some processes/tasks should not be automated
○ Keep human-in-the-loop to ensure they are active, involved, and aware
○ Research and study need to determine best automation candidates
○ Operational design needs to be structured to tasks

9. Key Considerations for Data Synthesis and
Visualization
• Workstation should make best use of human strengths:
○ Recognizing patterns
○ Using conceptual models and formulating mental models
○ Judgment and decision making when dealing with complex, incomplete or

conflicting data
○ Applying adaptive strategies in rapidly changing situations
• Human prefers ability to align data to their mental model
○ Too much data can disconnect human from process
○ Presentation of data can weaken mental models
■ Adaptability of display preferences and visualization of data
■ Human control over decision support tools is key - adapt/accept/reject decisions
10. Key Considerations for Data Synthesis and
Visualization
• New outputs or systems can be ignored or dismissed
○ Add workload under time constraints
○ Time and training to learn system may be inadequate
• Humans must trust and understand system for it to influence “decision”
• Style of forecaster influences use of tool

11. Forecasting Data Synthesis Considerations
• Understand forecasting decision-making better to formulate tools, mitigate
data overload and ensure optimal visualization/ interaction with systems and
workstations
○ Little work has been done to date specific to forecasting community
○ Differentiate needs between forecasting environments (i.e. severe weather
forecasting; nominal vs off nominal operations)
Confidential and Proprietary. Do Not Distribute. 11
• Heuristics Enhancement
○ Implement “lessons learned” approach to identify potential biases or possible
inclination for missed alarm/false alarm
○ Implement collaborative decision making approach to reduce introduction of
individual previous experience bias
• Study best forecasters and poor forecasters to determine what influences
accuracy and understand performance indicators

Editor's Notes
Maintain skills and keep professional “fresh”
Help professional to identify faulty or suspicious data and question system when necessary
Aid situation awareness, memory, or formulate mental models
Big data is an all-encompassing term for any collection of data sets so large and complex that it becomes difficult to process using on-hand data management tools or traditional data processing applications.
Style of forecaster – some find creative and positive ways of using new data and visualizations others are resistant to change (education and training crucial)
