Summary: A comprehensive BigData syllabus encompasses foundational concepts, essential technologies, data collection and storage methods, processing and analysis techniques, and visualisation strategies. Fundamentals of BigData Understanding the fundamentals of BigData is crucial for anyone entering this field.
This automation not only increases efficiency but also enhances the accuracy of data interpretation, allowing organisations to focus on more strategic tasks. Scalability Machine Learning techniques are designed to handle vast amounts of data, making them well-suited for bigdata applications. predicting house prices).
Unsupervised Learning Unsupervised learning involves training models on data without labels, where the system tries to find hidden patterns or structures. This type of learning is used when labelled data is scarce or unavailable. It’s often used in customer segmentation and anomaly detection.
Unsupervised learning algorithms, on the other hand, operate on unlabeled data and identify patterns and relationships without explicit supervision. Clustering algorithms such as K-means and hierarchical clustering are examples of unsupervised learning techniques. What is cross-validation, and why is it used in Machine Learning?
Feature engineering Game tracking data is captured at 10 frames per second, including the player location, speed, acceleration, and orientation. and BigData Bowl Kaggle Zoo solution ( Gordeev et al. ). Our feature engineering constructs sequences of play features as the input for model digestion.
B BigData : Large datasets characterised by high volume, velocity, variety, and veracity, requiring specialised techniques and technologies for analysis. C Classification: A supervised Machine Learning task that assigns data points to predefined categories or classes based on their characteristics.

Unsupervised learning, on the other hand, deals with unlabelled data, where the algorithm tries to find patterns, similarities, and differences without any specific target variable. The goal is to discover hidden structures and insights within the data.
Overfitting occurs when a model learns the training data too well, including noise and irrelevant patterns, leading to poor performance on unseen data. Techniques such as cross-validation, regularisation , and feature selection can prevent overfitting. In my previous role, we had a project with a tight deadline.
While doing this, it is very much necessary to carefully take sample data out of the huge data that truly represents the entire dataset. This data can be used to pass as an input to the neural network maintaining a small batch size. The steps for SVM are given below: For SVM, small data sets can be obtained.
The data science team must sometimes work with limited training data in the order of tens of thousands of records given the nature of their use cases. To reduce variance, Best Egg uses k-fold crossvalidation as part of their custom container to evaluate the trained model.
