Tech Talk: Declarative Reasoning with Timelines: The Next Step in Event Processing
Speaker: Ryan Michael, VP of Engineering @Datastax
Abstract: At the heart of modern data processing lies events. Events describe the roughest, most complete picture available of what has happened in the world, and practically every form of data processing ultimately begins with events.
While the power of event processing has increased since the emergence of streaming data processing, current systems are still difficult to use when working on problems that deal with time and order, such as predictive AI/ML. Handling these problems requires a new kind of query language - a way to declaratively reason about events over time.
In this talk, we introduce the concept of timelines. Timelines are an intuitive abstraction for reasoning about temporal values. They support a broad range of useful operations which can be efficiently computed at scale. We will demonstrate the power and differentiation of timelines:
- How timelines allow declarative queries over events and time in a simple and intuitive manner
- Why timelines are ideal for applications such as behavioral predictions, trend analysis, and forecasting, and how existing solutions such as streaming SQL fall short.
- How to execute timeline based queries using the open-source Kaskada event-processing engine.

Tech Talk 2: Turbocharging Model Performance by Super-sizing Your Data
Speaker: Ram Seshadri, Senior Program Manager @Google
Abstract: As data scientists and ML engineers, we often dedicate countless hours to fine-tuning hyperparameters of complex algorithms, particularly neural networks, in pursuit of optimal model performance. This talk will introduce a set of powerful open-source libraries, developed by the speaker, that enable a similar level of optimization for your data itself. Discover the capabilities of pandas-dq, featurewiz, Sulo model class, and lazytransform libraries as they empower you to enhance data quality, augment your data through feature engineering, and streamline feature selection for tabular datasets, including time series data.
The presentation will include a detailed walkthrough of an example notebook, illustrating how these innovative libraries can be harnessed to boost model performance in tabular and time series data contexts. We will explore strategies for refining data quality, addressing target imbalances, optimizing cross-validation, and effectively executing feature engineering and feature selection. Elevate your models to new heights by unlocking the full potential of your data, and learn how to troubleshoot underperforming segments for even greater results.
