Where we are nowadays – Data Science Lifecycle

The Data Science lifecycle process comprises five key stages: Business Understanding, Data Acquisition, Modeling, Deployment, and Customer Acceptance. A detailed comprehension of the client’s business challenge is necessary to get the process started. For example, to predict the loss of customers in the domain of retail, it is critical to understand the client’s business, needs and expectations. Engaging subject matter experts helps identify underlying problems. Usually, a business analyst collects data from the client and sends it to a team of data scientists for analysis.

Once the problem is clearly defined, the next step is gathering relevant information and breaking down the problem into smaller components. Identifying data sources, such as web server logs and digital libraries, is the initial phase of a data science project. Data collection involves obtaining information from reputable internal and external sources, using methods like third-party APIs or web scraping with Python.

Next, data preparation includes selecting relevant data, cleaning it, merging it with other data sets, treating missing values by removing or changing them, purging incorrect information, and identifying and addressing outliers. Feature engineering can be used to create new data and extract new features from existing ones. Any unnecessary columns or functions should be eliminated, and the data needs to be formatted based on the model’s requirements.The longest and most important step across the entire life cycle is data preparation.

Moving to the modeling phase, the provided data serves as input, and the goal is to create the desired result. Depending on the problem type—regression, classification, or clustering—the appropriate machine learning algorithm is chosen. Adjusting hyperparameters is crucial to achieve desirable results. Model assessment follows, evaluating accuracy and correctness.

Finally, the tested and validated model is deployed to a production environment, such as a server or cloud platform, for making predictions on new data. The deployment stage involves testing, packaging, and performance monitoring. The ultimate goal is to utilize the information extracted from the data to enhance business operations — a critical step for companies leveraging data science.

Sharing fundamental methods / technologies – What do Data Scientists need?

Data science is a rapidly evolving field that requires a deep understanding of mathematical, statistical, and computational principles. However, regardless of the specific use case or industry, there are fundamental methods and technologies that apply universally. For instance, data cleaning and preprocessing, exploratory data analysis, feature selection and model validation are crucial steps that must be carried out in every data science project. 

Data scientists often need GPUs for model training, which might not always be easily accessible as an Open source product. However, using libraries that support GPUs can provide a solution. GPUs significantly accelerate the training of neural networks in deep learning, contributing to rapid progress in the field. Popular open-source tools like TensorFlow, PyTorch, and CUDA support GPU acceleration, making deep learning models faster and more efficient.

Access to data services is critical in data science, particularly for big data, where large volumes of data are generated and stored in various formats. Open-source tools like Apache Hadoop and Apache Spark streamline data access, providing distributed computing frameworks with support for accessing data from various sources. Other tools like Apache Kafka and Apache NiFi enable real-time data ingestion and streaming, facilitating data collection and analysis. Platforms like Kaggle host public datasets, and there are many other open-source datasets available for analysis.

Common programming languages (Python, R, SQL) and popular libraries/frameworks (Pandas, NumPy, Scikit-learn, TensorFlow) are widely used in data science applications. Sharing these methods and technologies allows data scientists to collaborate efficiently and create transferable solutions. Various open-source platforms, such as Jupyter, Apache Zeppelin, KNIME, and data visualization tools like Matplotlib, contribute to a diverse ecosystem.

Editing and fine tuning existing models is crucial in data science, enabling researchers to adapt pre-existing models to specific use cases. Hugging Face provides pre-trained models for natural language processing that can be fine-tuned, saving time and resources while promoting knowledge sharing among data scientists. This ability to edit and fine-tune models is essential, and Hugging Face simplifies the process for researchers and practitioners.

Why is a Data science platform important?

In summary, an effective data science process demands tools that are easily consumable, eliminating concerns about assembling components, compliance policies, and organizational barriers. Having a data science platform is crucial in meeting these needs by providing a secure connection to data and consolidating all necessary tools and technologies in one accessible place.

Open-source alternatives offer the advantage of customization, allowing users to tailor and expand features to suit specific use cases, offering flexibility and the freedom to select preferred tools and libraries.
