- TensorFlow Extended (TFX): A suite of tools for deploying machine learning models in production.
TensorFlow’s capabilities make it an excellent choice for data scientists interested in AI and advanced machine learning.
7. Keras
Keras is a high-level neural network API that runs on top of TensorFlow, making it easier for data scientists to build and train deep learning models. Keras provides an intuitive interface that allows for quick model building and experimentation, making it a favorite among data scientists.
Features of Keras include:
- Simple syntax: Keras’ user-friendly syntax makes it easy to learn and implement.
- Support for recurrent and convolutional networks: These networks are widely used in image and language processing tasks.
- Compatibility with multiple backends: While primarily used with TensorFlow, Keras can also work with other machine learning backends.
For data scientists venturing into deep learning, Keras offers a streamlined and efficient approach to model building.
8. Hadoop
Hadoop is another big data framework that remains relevant for data scientists in 2024, particularly for those working with massive datasets. While Spark has gained traction due to its in-memory processing, Hadoop is still widely used for distributed storage and processing of big data.
Key components of Hadoop include:
- HDFS (Hadoop Distributed File System): Manages data storage across distributed systems.
- MapReduce: A programming model for processing large datasets.
- YARN (Yet Another Resource Negotiator): Manages resources in Hadoop clusters.
Hadoop’s ability to handle large amounts of data makes it a vital tool for companies working with big data projects.
9. Microsoft Power BI
Power BI, a business intelligence tool by Microsoft, is a popular choice for creating data visualizations and interactive reports. It allows data scientists to transform raw data into meaningful insights and share these insights with decision-makers.
