Challenges Of Machine Learning
Machine learning (ML), an indispensable cog in modern technology, allows the emulation of learning-like decisions without explicit programming. Yet developing and designing machine learning systems is not as simple as it might seem. Quite a huge number of challenges, in fact, press for attention in this domain of study.
- Good Data Is the Name of the Game
- High-quality data are strong engines for machine learning.

Difference Between Data Science and Machine Learning
The evolution of machine learning
- The First Steps: 1940s-1950s
- As soon as computers were invented and emerged forcedly on the face of the planet, philosophers, engineers, and other people began to wonder if machines could think like humans.
- Alan Turing was a mathematician who emphasized machines should pour over problems like humans and theorized such an ability.
- Simple programs or algorithms were made that could “learn” with Data, mainly for simplified mathematically oriented board games.
- Because of these reasons, the Minimum Machine Theory was stuck to large slow systems of information processing.
- Rule-Based Learning (1950s-1970)
- Early methods depended on writing rules by humans for machines to follow. An example would be, “If it is sunny, one should go outside.”
- While this is very simple to accomplish, it misses many other complex problems.
- In the same breath, scientists took a chance at the “neural networks,” drawing from examples via the human brain.
- Nevertheless, the systems of computers were immature to get that remain accepted or certified.
- Increased Data (1980s-90s)
- The computers are faster, cheaper, and able to collect huge amounts of Data.
- Now machine learning has changed itself from using rules to finding patterns in Data.
- The introduction of techniques, including “Decision Trees” and “Support Vector Machines”.
- Neural networks have begun to gain effectiveness, but still with large restrictions on their applied domains.
- Big Data and Current Machine Learning (2000s-Now)
- The internet, phone, and computerization have created enormous flows of Data.
- Faster and more powerful processing brought machine learning to huge heights of improvement.
- Neural networks improved and became capable of:
- Recognizing faces in a photo.
- Automatic translation of languages.
- Prediction of what products one might like to buy.
- Deep learning emerged as a technique consisting of a neural network with multiple layers capable of solving complex problems such as speech recognition and image processing.
Conclusion To Difference Between Data Science and Machine Learning
- Although the two disciplines are very similar, their roles are quite unalike.
- Data science is a broad field that encompasses anything and everything data-related-the collecting, analyzing, and interpreting for further insight.
- On the other hand, machine learning is part of the data science domain that revolves around teaching machines to learn from data in order to make decisions in near real-time without being told what to do in detail.
- Data scientists do a lot of work involving the cleaning of data, data visualization, and the analysis of the data.
- Machine learning engineers pay their attention specifically to building models that could predict or make the right decisions from certain underlying patterns within the data.
- They work together sometimes just to redefine the rules of innovation and change existing industries.
