Machine learning is a subset of artificial intelligence that uses statistical techniques to give computer systems the ability to "learn" with data, without being explicitly programmed. The goal of machine learning is to build algorithms that can receive input data and use statistical analysis to predict outcomes accurately. There are three main types of machine learning: supervised learning, unsupervised learning, and reinforcement learning. Popular machine learning algorithms include logistic regression, naive bayes, decision trees, k-means clustering, and neural networks. Machine learning is used in many applications like web search, computer vision, finance, and robotics.

Innovations in technology has revolutionized financial services to an extent that large financial institutions like Goldman Sachs are claiming to be technology companies! It is no secret that technological innovations like Data science and AI are changing fundamentally how financial products are created, tested and delivered. While it is exciting to learn about technologies themselves, there is very little guidance available to companies and financial professionals should retool and gear themselves towards the upcoming revolution.
In this master class, we will discuss key innovations in Data Science and AI and connect applications of these novel fields in forecasting and optimization. Through case studies and examples, we will demonstrate why now is the time you should invest to learn about the topics that will reshape the financial services industry of the future!

Machine Learning is the art of deriving models from our Big Data collections – harvesting historic patterns and trends – and applying those models to new data in order to rapidly and adequately respond to that data. This presentation will explain and demonstrate in simple, straightforward terms and using easy to understand practical examples what Machine Learning really is and how it can be useful in our world of applications, integrations and databases.

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).

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).
Techniques to optimize the pagerank algorithm usually fall in two categories. One is to try reducing the work per iteration, and the other is to try reducing the number of iterations. These goals are often at odds with one another. Skipping computation on vertices which have already converged has the potential to save iteration time. Skipping in-identical vertices, with the same in-links, helps reduce duplicate computations and thus could help reduce iteration time. Road networks often have chains which can be short-circuited before pagerank computation to improve performance. Final ranks of chain nodes can be easily calculated. This could reduce both the iteration time, and the number of iterations. If a graph has no dangling nodes, pagerank of each strongly connected component can be computed in topological order. This could help reduce the iteration time, no. of iterations, and also enable multi-iteration concurrency in pagerank computation. The combination of all of the above methods is the STICD algorithm. [sticd] For dynamic graphs, unchanged components whose ranks are unaffected can be skipped altogether.
The Building Blocks of QuestDB, a Time Series Databasejavier ramirez
Talk Delivered at Valencia Codes Meetup 2024-06.
Traditionally, databases have treated timestamps just as another data type. However, when performing real-time analytics, timestamps should be first class citizens and we need rich time semantics to get the most out of our data. We also need to deal with ever growing datasets while keeping performant, which is as fun as it sounds.
It is no wonder time-series databases are now more popular than ever before. Join me in this session to learn about the internal architecture and building blocks of QuestDB, an open source time-series database designed for speed. We will also review a history of some of the changes we have gone over the past two years to deal with late and unordered data, non-blocking writes, read-replicas, or faster batch ingestion.
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?

6. WHAT IS MACHINE LEARNING?
Machine Learning gives “computers the ability to learn without being explicitly programmed.”
(Samuel, A., 1959)
Machine Learning is the subset of Artificial Intelligence, that deal with the extraction of
patterns from data sets.
•This means that the machine can find rules for optimal behavior, but also can adapt to changes in the world
Because of new computing technologies, machine learning today is not like machine learning
of the past.
It was born from pattern recognition and the theory that computers can learn without being
programmed to perform specific tasks; researchers interested in artificial intelligence wanted
to see if computers could learn from data.

Characteristics Explanation
The ability to perform
automated data
visualization
Machine learning offers several tools that provide rich snippets of
data which can be applied to both unstructured and structured data.
With the help of user-friendly automated data visualization platforms
in machine learning, businesses can obtain a wealth of new insights to
increase productivity in their processes.
Optimized to learn
complex patterns
Machine learning models are designed to be optimized to learn
complex patterns. In comparison to statistical models or decision tree
models, predictive models greatly excel, when you have very complex
patterns in data.
Account for interactions
and
nonlinear relationships
Machine learning predictive models can account for interactions in the
data and nonlinear relationships to an even better degree than
decision tree models.
Few assumptions These models are powerful because they have very few assumptions.
They can also be used with different types of data.
