TensorFlow vs scikit-learn: What are the differences?

Introduction:

When it comes to machine learning and deep learning libraries, TensorFlow and scikit-learn are two popular choices that serve different purposes. Understanding the key differences between these two libraries can help practitioners choose the right tool for their specific tasks.

  1. Data Types: TensorFlow is primarily focused on deep learning tasks and works well with tensor data structures. On the other hand, scikit-learn is more versatile and capable of handling various data types including numerical, categorical, and textual data. This makes scikit-learn a preferred choice for machine learning tasks beyond deep learning.

  2. Nature of Algorithms: TensorFlow is tailored towards implementing neural networks and deep learning models, making it a go-to tool for complex neural network architectures. In contrast, scikit-learn is designed for traditional machine learning algorithms such as regression, classification, clustering, and dimensionality reduction. This difference in focus dictates the type of tasks each library is best suited for.

  3. Ease of Use: Scikit-learn is renowned for its user-friendly API and ease of implementation, making it a popular choice for beginners and rapid prototyping. On the other hand, TensorFlow's complexity stems from its deep learning capabilities, requiring a more advanced understanding of neural networks and computational graphs.

  4. Community Support: Scikit-learn boasts a larger and more established community compared to TensorFlow, which translates to extensive documentation, tutorials, and support forums. This community-driven aspect of scikit-learn facilitates learning and problem-solving for users at all levels.

  5. Deployment Flexibility: TensorFlow provides more options for deploying models in production environments, especially when it comes to deploying deep learning models in production-ready systems. Its integration with tools like TensorFlow Serving and TensorFlow Lite offers enhanced deployment capabilities compared to scikit-learn.

  6. Performance and Scalability: TensorFlow is optimized for scalability and performance, particularly in training large deep neural networks on distributed computing systems. This scalability advantage makes TensorFlow suitable for handling big data and running computationally intensive computations efficiently compared to scikit-learn.

In Summary, understanding the key differences between TensorFlow and scikit-learn can guide practitioners in selecting the most suitable library for their machine learning and deep learning tasks.

Decisions about scikit-learn and TensorFlow

Pytorch is a famous tool in the realm of machine learning and it has already set up its own ecosystem. Tutorial documentation is really detailed on the official website. It can help us to create our deep learning model and allowed us to use GPU as the hardware support.

I have plenty of projects based on Pytorch and I am familiar with building deep learning models with this tool. I have used TensorFlow too but it is not dynamic. Tensorflow works on a static graph concept that means the user first has to define the computation graph of the model and then run the ML model, whereas PyTorch believes in a dynamic graph that allows defining/manipulating the graph on the go. PyTorch offers an advantage with its dynamic nature of creating graphs.

For data analysis, we choose a Python-based framework because of Python's simplicity as well as its large community and available supporting tools. We choose PyTorch over TensorFlow for our machine learning library because it has a flatter learning curve and it is easy to debug, in addition to the fact that our team has some existing experience with PyTorch. Numpy is used for data processing because of its user-friendliness, efficiency, and integration with other tools we have chosen. Finally, we decide to include Anaconda in our dev process because of its simple setup process to provide sufficient data science environment for our purposes. The trained model then gets deployed to the back end as a pickle.

A large part of our product is training and using a machine learning model. As such, we chose one of the best coding languages, Python, for machine learning. This coding language has many packages which help build and integrate ML models. For the main portion of the machine learning, we chose PyTorch as it is one of the highest quality ML packages for Python. PyTorch allows for extreme creativity with your models while not being too complex. Also, we chose to include scikit-learn as it contains many useful functions and models which can be quickly deployed. Scikit-learn is perfect for testing models, but it does not have as much flexibility as PyTorch. We also include NumPy and Pandas as these are wonderful Python packages for data manipulation. Also for testing models and depicting data, we have chosen to use Matplotlib and seaborn, a package which creates very good looking plots. Matplotlib is the standard for displaying data in Python and ML. Whereas, seaborn is a package built on top of Matplotlib which creates very visually pleasing plots.

What is scikit-learn?

scikit-learn is a Python module for machine learning built on top of SciPy and distributed under the 3-Clause BSD license.

What is TensorFlow?

TensorFlow is an open source software library for numerical computation using data flow graphs. Nodes in the graph represent mathematical operations, while the graph edges represent the multidimensional data arrays (tensors) communicated between them. The flexible architecture allows you to deploy computation to one or more CPUs or GPUs in a desktop, server, or mobile device with a single API.

What are some alternatives to scikit-learn and TensorFlow?
PyTorch
PyTorch is not a Python binding into a monolothic C++ framework. It is built to be deeply integrated into Python. You can use it naturally like you would use numpy / scipy / scikit-learn etc.
Keras
Deep Learning library for Python. Convnets, recurrent neural networks, and more. Runs on TensorFlow or Theano. https://keras.io/
H2O
H2O.ai is the maker behind H2O, the leading open source machine learning platform for smarter applications and data products. H2O operationalizes data science by developing and deploying algorithms and models for R, Python and the Sparkling Water API for Spark.
XGBoost
Scalable, Portable and Distributed Gradient Boosting (GBDT, GBRT or GBM) Library, for Python, R, Java, Scala, C++ and more. Runs on single machine, Hadoop, Spark, Flink and DataFlow
Apache Spark
