“Jobs in data science will escalate by 27.9%, with market growth reaching an astounding $322.9 billion by 2026."

Excerpts from the Bureau of Labour Statistics

That is just the warm-up; if you thought that AI is done and out. Millions of data science aspirants pivot into the industry every year, seeking to build a highly rewarding data science career. International business markets have become volatile, being overly dependent on market analysis, based on the racing numbers. Brand sentiment, consumer behavior, a shift in demand, online brand conversations; and many other criteria pivot the way ahead for businesses worldwide. Today, ‘reading between the lines’ is a rage while planning to generate meaningful business insights. This leads your pack way ahead in the market scene, crushing your competitor’s streak, and helping you to catch up with the forerunners.

Data Science Professionals around the world are levied with the responsibility of churning out greater business insights with the data in hand. This leaves them with no other option; instead to democratize computing tools and techniques. They have worked hard upon building sophisticated data-crunching machines over the past decades, that are creating waves in the international industry. They work with specialized machine learning algorithms that are designed to stand the test of dynamic times; resolving real-world complex problems.

Broadly, machine learning algorithms can be classified as:

  • Supervised learning models: Under this model, the machine learns under supervision; wherein it contains a model that can predict with the help of a labeled dataset, the target answer is already known.
  • Unsupervised learning models: In this, the machine uses unlabeled data and learns on itself without any supervision. Here, the machine tries to find a pattern in the unlabeled data and gives a response.
  • Semi-supervised learning models: The type of ML algorithm that represents intermediate ground between supervised and unsupervised learning algorithms; alongside using a combination of labeled and unlabeled datasets during the training period.
  • Reinforcement learning models: It refers to taking suitable action to maximize reward in a particular situation. The reinforcement agent decides what to do to perform the given task. In the absence of any trajectory, these models learn from experience.

Going forward, there are many key data science tools and algorithms that are being deployed by efficient data science professionals in recent times to leverage meaningful results. Machine learning, being a highly-responsive field of work, caters to imparting machines with human-like capabilities to learn, comprehend and adapt. Listed below are the top 10 Machine learning Algorithms that assist in making this happen:

  1. Linear Regression
    A popular ML algorithm based on supervised learning; targeted to perform a regression task. It helps predict the value of a dependent variable based on a given independent variable.
  2. Logistic Regression
    A supervised learning algorithm designed to identify the binary classification of data points.
  3. Hypothesis Testing
    A must-have skill for a data scientist; as it is the process of using statistical tests to verify if the hypothesis is true or otherwise. Testing the inevitability of the occurrence is checked by this test.
  4. Clustering
    Segmentation or clustering is an unsupervised learning algorithm where a dataset is grouped into unique, differentiated clusters. The output is unknown to the analyst; hence it is an unsupervised learning algorithm.
  5. ANOVA
    The one-way analysis of variance (ANOVA) test is used to determine whether the mean of more than two groups of datasets are significantly different from each other. The analysis of variance works by comparing the variance between the groups to that of within the group variance.
  6. Decision Tree
    It is used for predictions and classification in ML, with a given set of inputs, that helps in easy mapping of the outcomes.
  7. K-Nearest Neighbour 
    KNN is a supervised learning model that is parameter agnostic and does not make assumptions about how the data is distributed. In simpler words, it does not require an explicit training phase before classification.
  8. Naïve Bayes
    Based on the Bayes theorem, it is used for solving classification problems, with features independent of one another.
  9. Neural Networks
    It is inspired by the human nervous system, which is used in finding patterns in complex data and providing forecasts, and classifying data points.
  10. Conjoint Analysis
    It is widely used in market research to help identify customers’ preferences for various attributes of a product. This helps brand managers to identify which features would customer’s trade-off for a certain price point.

To build a lasting data science career, it is critical to equip oneself with the best skillset and data science certifications. An in-depth understanding of these ML algorithms is a must-have if data science is the dream that you wish to fulfill. Beginning informed is halfway closer to the world of data sciences.
