Machine learning, deep learning: What are the differences in data science?

Term indicatesartificial intelligence Mainly down to a concept, without further technical details on how to achieve it. Moreover, some optimization technologies, for example, were considered artificial intelligence 30 or 40 years ago, but they are no longer so today.

If we look at the technologies used today in artificial intelligence, we often find machine learning and/or deep learning.

What is deep learning and how does it work?

Deep learning is a class of brain-inspired machine learning algorithms (hence they are also called “neural networks”) that have shown amazing results on complex tasks like image analysis or the aforementioned NLP.

More precisely, the term deep refers to the fact that a neural network consists of many layers connected in series, hence the idea of ​​depth.

Machine learning is based on general algorithms, whose specificity must be adjusted according to the application situation. In a way, it’s like giving a computer a blank sheet of data and some data to make notes about the correlations it notices within that data (without human intervention).

So in fact, deep learning is a subclass of machine learning algorithms.

MLOps, Machine Learning in Production

Data science is definitely a business-oriented field. However, integrating all of these new technologies, all of this complexity within the company is a real challenge.

Therefore, an additional aspect of data science is the set of IT methods and practices developed with the aim of integrating data projects into companies.

MLOps, as well as DataOps, are micro-approaches (combining methods, processes, tools, and team organization) aimed at facilitating each phase of a data project.

Data science uses

Data science helps us achieve some major goals that were not possible or required a great deal of time and energy just a few years ago, such as:

Examples of data science and applications:

  • Anomaly detection (fraud, disease, crime)
  • Classification (background checks; an email server that rates emails as “important”)
  • Forecasting (sales, revenue and customer retention)
  • Pattern spotting (weather patterns and financial market patterns)
  • Recognition (face, voice, text)
  • Recommendation (based on earned preferences, recommendation engines can refer you to movies, restaurants, and books)
  • Regression (predicting food delivery times, predicting home prices based on amenities)
  • Optimization (scheduling shared rides and package delivery)

Here are some in-depth examples of how companies are using data science to innovate and disrupt their sectors, create new products, and make the world around them more efficient:

Data science in healthcare

Data science has led to a number of breakthroughs in the healthcare industry. With a vast network of data now available across everything from electronic medical record records to clinical databases to personal fitness trackers, medical professionals are finding new ways to understand disease, practice preventive medicine, diagnose diseases faster, and explore new treatment options. The sensitivity of patient data makes data security a greater focus in healthcare.

Data science in self-driving cars

Data science is on the way, too. executed Tesla, Ford and Volkswagen Predictive analytics in their autonomous vehicles. These cars use thousands of cameras and tiny sensors to transmit information in real time. Using machine learning, predictive analytics, and data science, self-driving cars can adapt to speed limits, avoid dangerous lane changes, and even pick up passengers on the fastest route.

Data science and logistics

UPS uses data science to maximize efficiency, both internally and along its delivery routes. The company’s Integrated On-Route Navigation and Optimization (ORION) tool uses statistical models and algorithms backed by data science that create optimal routes for delivery drivers based on weather, traffic, and construction. It is estimated that data science saves a logistics company millions of gallons of fuel and delivery miles each year.

Data Science in Entertainment

Ever wonder how Spotify seems to recommend that perfect song for you? Or how does Netflix know just what shows to love? Using data science, these streaming media giants learn your preferences to carefully curate content from their vast libraries that they think will precisely appeal to your interests.

Data science in product and sales andMarketing

Many companies rely on data scientists to build time series forecasting models that help with inventory management and supply chain optimization. Data scientists are sometimes tasked with making proactive recommendations based on budget projections made through financial models. Some even use data mining to segment customers by behavior, and tailor future marketing messages to attract specific groups based on past brand interactions.

Data Science in Finance

Machine learning and data science have saved the financial industry millions of dollars, and an immeasurable amount of time. For example, you use a company’s contract information platform J.P. Morgan Natural language processing to process and extract vital data from thousands of trade credit agreements annually.

Thanks to data science, what would have taken around hundreds of thousands of hours of manual labor to complete is now finished in just a few hours. In addition, financial technology companies such as Stripe and Paypal are investing in data science to create machine learning tools that quickly detect and prevent fraudulent activity.

Data Science in Cyber ​​Security

Data science is useful in every industry, but it may be most important in cybersecurity. For example, the international cybersecurity company Kaspersky uses science and machine learning to discover hundreds of thousands of new malware samples every day. The ability to instantly discover and learn new avenues of cybercrime through data science is essential to our safety and security in the future.
