In this session, you’ll learn about the main concepts behind Time Series: preprocessing, alignment, missing value imputation, forecasting, and evaluation. Together we will build a demand prediction application: first with (S)ARIMA models and then with machine learning models. The codeless examples are built in the KNIME Analytics Platform using the Time Series components provided for preprocessing, transforming, aggregating, forecasting, and inspecting time series data. You will also be provided example workflows to use later in your own projects.

Language-Integrated Query (LINQ) is a feature of the C# programming language that lets you work with data with SQL-like syntax. This presentation starts with the basic syntax of a LINQ query. You'll also learn about core features like filters, joins, and grouping. Additionally, you'll see how LINQ has a comprehensive set of standard operators for whatever you need to do with data. After this presentation, you'll understand how LINQ can help with data manipulation tasks.

Many people believe that you have to either be a specialist or a generalist. An expert or a jack-or-jill of all trades. But those who can do both, who can balance these seemingly contradictory beliefs, consistently outperform. Matt Coatney, a C-level technology executive, and AI practitioner talk about his own journey and missteps, and how a multi-disciplinary approach including deep technical expertise and core skills led him to personal and professional success.

This webinar will cover an end-to-end study of attrition – the dwindling number of the workforce – in a company. The end goal of an attrition recommendation system is to develop retention strategies to prevent employee churn. In this session, we will discuss the process starting from data collection & preprocessing to model development and deployment. It will be presented by an award-winning HR consultant with over 17+ years of consulting in HR transformation and system implementation projects across the globe.

Tutorials

Naive Bayes is a technique from machine learning, useful for making classifications. Naive Bayes has all sorts of applications ranging from facial recognition to weather prediction to medical diagnoses to news classifications among others. In this webinar, we provide an introduction to Naive Bayes methods through theory and coding examples. By the end of the webinar, students should acquire a strong understanding of this technique.

The key differentiator for high-performance data scientists is not technical depth, but the ability to act as a translator between the business and the technology practice. In this talk, Jeremy Adamson will share five tips for how practitioners can move their careers to the next level by leveraging relationships, reconsidering their role as data scientists, and controlling the data narrative in their organizations.

In this session, Oscar Baruffa will demystify the hiring process, highlight why job hunting is so difficult, focus on where he thinks most candidates can make the biggest difference, give examples of what improvements to make, and briefly describe a strategy he uses to maintain his energy and good emotional state when looking for work.

Tutorials

This webinar is focused to make you capable of getting started with the new generation data warehouse i.e. Snowflake. You will be understanding Snowflake architecture, its user interface, and the data caching feature of Snowflake. During the webinar, there will be a lot of instructor-led demos to provide you with a pragmatic experience regarding the Snowflake Platform.

Tutorials

Data scientists at the start of their careers often have the misconception that their job will be largely focused on training and improving models in a Jupyter notebook. The reality is that most data science value is created outside of a notebook. 
This crash course is intended for data scientists with basic knowledge of developing machine learning models in a Jupyter notebook setting. 

Tutorials

Tree-based models such as decision trees, random forests, and boosted trees provide powerful predictions and are fast to compute. There are many different ways to fit these models in R, including the rpart, randomForest, and xgboost packages. 

Tutorials

In this talk Daniel will present a systematic process where ML is an input to improve our ability to make better decisions, thereby taking us closer to the prescriptive ideal.  In a nutshell, this process starts by clearly identifying the KPI or metric that we want to improve (eg. revenue).  This metric itself may not be actionable, so we may have to decompose it into actionable metrics.

Want to ace your upcoming Data Science job interview? Join Nick Singh, author of the best-selling book, Ace the Data Science Interview, to learn how to solve SQL, probability, ML, coding, and case interview questions asked by FAANG + Wall Street. He'll also share the contrarian job hunting tips that led him to work at Facebook, Google, and an ML startup.

Tutorials

In this session, we'll explore how to incorporate data science and AI/ML into Kubernetes development workflows, taking advantage of the platform's openness and rich ecosystem. Using well-known open-source tools for Data Science such as Jupyter Notebooks and TensorFlow, we will explore different strategies to accelerate and automate ML workloads with Kubernetes.

Tutorials

As data scientists and machine learning professionals make the transition from theory to applied data science, they naturally expand their skill set beyond Python or Pandas.  They need to understand how to leverage a key-value store or database to store their embeddings or features, and how to load and fetch them very quickly for online predictions or to perform complex operations in milliseconds for real-time use cases. 

Tutorials

The number of websites on the internet is estimated to be around 2 billion. Web scraping turns the entire world wide web into your data set. In this webinar, we will introduce how to scrape a website using the BeautifulSoup package in Python. We will discuss how to navigate the HTML DOM to find data that interests you, some best practices, the legality of web scraping, and briefly touch on how to build and automate a web scraper on the cloud using Azure Functions.
