What is the Machine Learning Pipeline?
A pipeline is a collection of algorithms chained, concatenated, and scrambled in some way to handle a stream of data; it contains inputs and outputs. It may or may not contain a state as well. A machine learning algorithm takes clean data and learns a pattern to predict fresh data. As a result, you’ll need to preprocess that data to provide input data for the machine learning algorithm. Similarly, the ML algorithm’s output is only a number in the software that must be analyzed to do some action in the real world. You will have to do the same thing again and again without a pipeline. This is where the pipeline comes in; you can combine all of these actions into a single container in a step-by-step fashion so that once the data is imputed to the pipe, the operations are carried out sequentially until the correct data format is selected.
Why Machine Learning Pipelines?
Organizations can use machine learning models to discover opportunities and hazards, improve their company strategy, and provide better customer service. However, it is time-consuming to acquire and process data for machine learning models, utilize it to train and test them, and finally operationalize.
Companies want their data science teams to produce relevant business predictions sooner by speeding up the process. Machine learning pipeline monitoring allows you to operationalize machine learning models faster by automating procedures. Machine learning pipeline orchestration reduces the time it takes to create a new machine learning model and also helps increase the quality of your models. Although we refer to it as a pipeline, genuine pipelines are one-way and one-time only, which is not the case with machine learning pipelines. ML pipelines are iterative cycles in which each step is repeated several times. ML pipelines use CI/CD techniques to improve the accuracy of ML models and the quality of your algorithms. Data scientists from all industries employ automated machine learning processes to improve their models and accelerate development and deployment. Companies of all sizes see the advantages that machine learning models may provide in every department. Marketing, sales, product, and customer care departments are among the departments that want to use machine learning to analyze their data. Still, only major businesses can afford to staff a data science team large enough to handle all requests. A machine learning CI/CD pipeline can help a tiny data science team punch above its weight. Pipelines democratize access to machine learning models, allowing even small businesses to use machine learning to improve data-driven business choices.
Advantages of Machine Learning Pipeline
Improve the Customer Experience
You can develop machine learning models faster and apply them to more use cases with machine learning orchestration, allowing you to predict rather than react to consumer trends and understand customer preferences at a granular level, providing a better customer experience and increasing your bottom line.
Improve Data-Driven Decision-Making
Machine learning predictions enhance decision-making and add value to every part of your organization. However, building a model for each request can be time-consuming for the data science team. ML pipelines allow teams to break down silos and use AI predictions for better data-driven decision-making.
Allow Time for Your Data Science Team to Work
It’s uncommon to come across a company with a large data science staff to reply to everyone’s request for machine learning predictions for their use cases. Machine learning pipelines take care of many time-consuming duties that can be automated, thus, allowing them to focus on work that cannot be automated.
Improve Your Company Strategy
Machine learning in the CI/CD pipeline aids in developing more accurate machine learning models for your business management team to utilize in identifying opportunities, mitigating risks, and tracking demand, ensuring that your strategy keeps you ahead of the competition.
Implementing Pipeline in Sklearn
from sklearn.linear_model import LogisticRegression
from sklearn.preprocessing import StandardScaler
from sklearn.datasets import make_classification
from sklearn.model_selection import train_test_split
from sklearn.pipeline import Pipeline
Creating a sample dataset
X, y = make_classification(random_state=42)
print('Features are', X)
print('Labels are', y)
X_train, X_test, y_train, y_test = train_test_split(X, y, random_state=42)

Conclusion
We discussed the ML pipeline description, its uses, advantages, and implementation in sklearn. ML pipeline incorporates multiple algorithms into a single series, allowing us to write our code in a more quick and efficient manner. It can also embed data preprocessing and model-building steps into a single series.
