Generic _Composite_ in Python_ PyWeb TLV Meetup 07.08.2024.pdfAsher Sterkin
油
際際滷s of my presentation at PyWeb TLV Meetup. Share my experience of developing a generic implementation of the "Composite" design pattern using Python meta-programming capabilities.
Python was created by Guido van Rossum in the late 1980s and named after Monty Python. It is a general purpose, high-level programming language that supports multiple paradigms like object-oriented, functional, and imperative programming. Django is a Python web framework that grew out of a newspaper project and follows the MVC pattern, separating concerns into models, views, templates. It provides tools for authentication, forms, administration, and more so that developers can focus on their specific applications.
Deploying ML models in production, with or without CI/CD, is significantly more complicated than deploying traditional applications. That is mainly because ML models do not just consist of the code used for their training, but they also depend on the data they are trained on and on the supporting code. Monitoring ML models also adds additional complexity beyond what is usually done for traditional applications. This talk will cover these problems and best practices for solving them, with special focus on how it's done on the Databricks platform.
1. Coding and workflow automation are essential to scaling processes in the cloud. Low-coding strategies allow developers to automate workflows using Python and other languages.
2. Combining knowledge of MicroStrategy and Python is rare but important for automating development and operations tasks. The document proposes bringing on young developers with Python skills and coaching them on both technologies.
3. Automating common tasks like regression testing of reports against changing data models could be a starting point for such a combined team to build and test automation solutions.
I am shubham sharma graduated from Acropolis Institute of technology in Computer Science and Engineering. I have spent around 2 years in field of Machine learning. I am currently working as Data Scientist in Reliance industries private limited Mumbai. Mainly focused on problems related to data handing, data analysis, modeling, forecasting, statistics and machine learning, Deep learning, Computer Vision, Natural language processing etc. Area of interests are Data Analytics, Machine Learning, Machine learning, Time Series Forecasting, web information retrieval, algorithms, Data structures, design patterns, OOAD.
Data Scientists and Machine Learning practitioners, nowadays, seem to be churning out models by the dozen and they continuously experiment to find ways to improve their accuracies. They also use a variety of ML and DL frameworks & languages , and a typical organization may find that this results in a heterogenous, complicated bunch of assets that require different types of runtimes, resources and sometimes even specialized compute to operate efficiently.
But what does it mean for an enterprise to actually take these models to "production" ? How does an organization scale inference engines out & make them available for real-time applications without significant latencies ? There needs to be different techniques for batch (offline) inferences and instant, online scoring. Data needs to be accessed from various sources and cleansing, transformations of data needs to be enabled prior to any predictions. In many cases, there maybe no substitute for customized data handling with scripting either.
Enterprises also require additional auditing and authorizations built in, approval processes and still support a "continuous delivery" paradigm whereby a data scientist can enable insights faster. Not all models are created equal, nor are consumers of a model - so enterprises require both metering and allocation of compute resources for SLAs.
In this session, we will take a look at how machine learning is operationalized in IBM Data Science Experience (DSX), a Kubernetes based offering for the Private Cloud and optimized for the HortonWorks Hadoop Data Platform. DSX essentially brings in typical software engineering development practices to Data Science, organizing the dev->test->production for machine learning assets in much the same way as typical software deployments. We will also see what it means to deploy, monitor accuracies and even rollback models & custom scorers as well as how API based techniques enable consuming business processes and applications to remain relatively stable amidst all the chaos.

油
ML platform meetups are quarterly meetups, where we discuss and share advanced technology on machine learning infrastructure. Companies involved include Airbnb, Databricks, Facebook, Google, LinkedIn, Netflix, Pinterest, Twitter, and Uber.
This document discusses software variability management. It begins by defining software variability as the ability of a software system or artifact to be efficiently extended, changed, customized or configured for a particular context. It then provides examples of variability in iOS and GCC versions. Next, it discusses challenges in managing copies of software with variability and advantages of software product lines. Key aspects of software product line engineering covered include commonalities and variabilities, product derivation, and an example of enterprise resource planning systems. The document concludes by summarizing feature modeling and variability realization techniques including feature models, binding times, and design patterns.
This document discusses design patterns and principles. It begins by defining design patterns as repeatable solutions to common design problems. It then covers several design patterns including Singleton, Strategy, Adapter, Template, Factory, Abstract Factory, and Observer patterns. It also discusses low-level principles like Tell Don't Ask and high-level principles like the Single Responsibility Principle. Finally, it provides examples of how to implement some of the patterns and principles in code.
CodeIgniter is an open source PHP web application framework that uses the model-view-controller (MVC) architectural pattern. It provides features like a lightweight and fast system, clear documentation, and a friendly community of users. The framework includes libraries and helpers for common tasks like databases, forms, URLs, and more. Controllers handle requests and interact with models to retrieve and work with data, and views are used to display the data to the user.
Building machine learning service in your business Eric Chen (Uber) @PAPIs ...PAPIs.io

When making machine learning applications in Uber, we identified a sequence of common practices and painful procedures, and thus built a machine learning platform as a service. We here present the key components to build such a scalable and reliable machine learning service which serves both our online and offline data processing needs.
In this talk we'll look at simple building-block techniques for predicting metrics over time based on past data, taking into account trend, seasonality and noise, using Python with Tensorflow.
Consolidating MLOps at One of Europes Biggest AirportsDatabricks
油
At Schiphol airport we run a lot of mission critical machine learning models in production, ranging from models that predict passenger flow to computer vision models that analyze what is happening around the aircraft. Especially now in times of Covid it is paramount for us to be able to quickly iterate on these models by implementing new features, retraining them to match the new dynamics and above all to monitor them actively to see if they still fit the current state of affairs.
To achieve those needs we rely on MLFlow but have also integrated that with many of our other systems. So have we written Airflow operators for MLFlow to ease the retraining of our models, have we integrated MLFlow deeply with our CI pipelines and have we integrated it with our model monitoring tooling.
In this talk we will take you through the way we rely on MLFlow and how that enables us to release (sometimes) multiple versions of a model per week in a controlled fashion. With this set-up we are achieving the same benefits and speed as you have with a traditional software CI pipeline.

dbt Python models - GoDataFest by Guillermo SanchezGoDataDriven
油
Guillermo Sanchez presented on the pros and cons of using Python models in dbt. While Python models allow for more advanced analytics and leveraging the Python ecosystem, they also introduce more complexity in setup and divergent APIs across platforms. Additionally, dbt may not be well-suited for certain use cases like ingesting external data or building full MLOps pipelines. In general, Python models are best for the right analytical use cases, but caution is needed, especially for production environments.
