A very applied field in today’s time is machine learning. The task of training a machine is not an easy task. It comes up with its challenges. The first and foremost one is to have the skills of knowing how to interact with the machine. To converse with any computer or machine, we need to learn its language, and similarly, machine learning is no different. 

It is imperative to know which language is best for machine learning to excel in the field. Learning a programming language is no different than knowing how to ride a bicycle or drive a car. We need to know certain basic aspects of the language and its applications.

The focus of this article is exactly this. We will look at what is a programming language, understand what is machine learning, its use cases, which all companies employ machine learning and the heart of this article is what programming languages for machine learning are available. We’ll also know which is the best language for machine learning in 2023. 

What is a programming language?

A programming language is a computer language used by programmers (or developers) to interact with computers. These programming languages are written as a set of instructions to conduct particular tasks in specific languages such as  C, C++, Java, Python, and R.

Following are the types of programming languages:

• High-level programming language
  • Procedural Oriented programming language
  • Object-Oriented Programming language
  • Natural language
• Middle-level programming language
• Low-level programming language
  • Machine Language
  • Assembly Language
• Declarative / Imperative / Procedural
• General-purpose / Domain-Specific
• Object-oriented / Concurrent
• Command / Compiled / Script language
• Answer set

What is machine learning?

Machine Learning, a branch of Artificial Intelligence, creates dynamic, accurate, and stable automated models using mathematical relationships. It involves statistical techniques and algorithms that empower the machines to perform and improve specific tasks themselves with experience and without human intervention. These models are not defined by any hard-coded rules. The machine learns from the past data to discover patterns and identify relationships in the historical data and use these patterns to predict the new data automatically.

Machine learning is a subset of artificial intelligence while deep learning is the subset of machine learning. While they all might seem similar, they aren’t. They are co-related to each other but are different.

The steps in machine learning are as follows:

1. Collection of the data from various sources
2. Clean and prepare the data 
3. Choose the model
4. Training of the model
5. Evaluate the model
6. Tune the parameters
7. Predict the new data

There are several types of machine learning algorithms, as follows:

• Supervised Learning
• Semi-supervised Learning
• Unsupervised Learning
• Reinforcement Learning 

The algorithms are classified based on the learning types. Read about the different types of machine learning algorithms. 

Uses of Machine Learning

ML programming language is widely applicable in various domains such as e-commerce, logistics, healthcare, manufacturing, marketing, finance, energy, insurance, human resources, government & surveillance, digital media and entertainment, transportation, manufacturing, automobile, art & creativity.  

The applications of Machine Learning are:

• Algorithmic or stock market trading: Algorithms such as long short term memory (LSTM), Recurrent Neural network (RNN) are used for stock market trading. The models are tuned for the parameters taking the increase and decrease in stock prices and optimizing the trading strategies.
• Traffic Prediction: If you are commuting to a new place, then on the less traveled road Google Maps is your friend. The maps are effective in showing the correct path with the shortest route, forecasting the traffic conditions, and are also useful in suggesting what time one must depart from a place to reach a destination at a pre-defined arrival time.  It predicts traffic situations such as congestion, and slow-moving or clear routes by considering the average time on previous days at the same time and the real-time location of the vehicle from the map application and sensors.
• Forecast: Machine Learning also helps in predicting the prices of cabs, stocks, tariffs of hotels, and sales of stores on a time basis as well. 
• Image Recognition: Image segmentation, Object detection, and localization are popular use cases of machine learning to identify objects, persons, places, and digital images. Facebook suggests tagging friends by recognizing photos.
• Product Recommendation or Recommendation Engines: E-commerce sites auto-suggest similar products while placing orders on Amazon, Flipkart, and similarly entertainment sites recommend movies, and songs based on the last bought product and watched or browsed movie or song. These product recommendations are curated using statistical models. 
• Healthcare: Healthcare uses machine learning for detecting terminal diseases such as brain tumors, cancer, and non-terminal diseases.
• Fraud Detection: Detection of fraud in online transactions is one the biggest concerns for e-commerce retailers, banks, and payment merchants, and machine learning aids this need by models to ensure the transactions are safe and track down fraud customers.
• Voice Recognition: Machines recognizing voices have changed the face of homes and is one of the most popular use cases of machine learning. Voice recognition involves converting the voice commands into text. This is generally referred to as “Speech to text”, or “Speech recognition.” Apple’s Siri, Microsoft’s Cortana, Google Home Speakers, Amazon’s Alexa, and Google Assistant are various virtual assistants.
• Automatic Language Translation, Auto-corrections: The techniques used for machine translation are sequence to sequence that converts text from one language to another, and auto-corrects spelling errors as well. 
• Email Spam Filtering and Malware Detection: Machine learning also helps in detecting malware and spam in email by employing filters.

Companies using Machine Learning

Machine Learning is extensively used by big giants including Apple, Google, Microsoft, IBM, Intel, Twitter, Qubit, Baidu, and Salesforce as well as by startups. Some of the interesting ways the companies in which companies are using machine learning are:

Big corporate giants like Apple, Google, Microsoft, IBM, and more extensively use ML programming language. Not just the tech giants but small and mid-sized startups also rely on machine learning. The majority of tech companies use machine learning to enhance customer satisfaction by tapping into customer insights. For instance, Yelp, a local business review and social networking platform, introduced its own machine learning platform to consolidate all ML infrastructure. Yelp uses machine learning to filter out spam and inappropriate photos using picture classification technology. 

Similarly, one of the most popular social platforms, Instagram, relies on machine learning to tailor personalized content based on users’ interests. Here’s how Instagram is leveraging ML programming language:

On the other hand, private banks such as Axis, HDFC, and ICICI,  have employed chatbots to speed up the customer support services and automate the processes of reactivating the dormant accounts. Similarly, airline companies and payment merchants such as PayPal are also relying on chatbots to troubleshoot customer queries. 

Some more examples:

• Twitter uses artificial intelligence to drive user engagement by evaluating a tweet on a real-time basis and scoring each tweet
• Tesla employs unsupervised learning for self-driving cars. The cars are trained for detecting people and objects.

Now that you can see for real how ML programming language and AI are changing the way the world functions(for the better!), time to start learning the programming languages that can give you entry into this fascinating world.
