ML Case study with time-series data

Q1. Explain outliers and outlier detection algorithms
Ans. 
Outliers are data points that significantly differ from other data points. Outlier detection algorithms identify and remove these anomalies.
• Outliers are data points that fall far outside the normal range of values in a dataset.

• Outlier detection algorithms include statistical methods like Z-score, Tukey's fences, and machine learning techniques like isolation forests and one-class SVM.

• Outliers can skew statistical analy...read more

Q2. How to handle huge amount of data and what are the efficient ways of storing them
Ans. 
To handle huge amount of data efficiently, consider using distributed storage systems, data compression techniques, and data partitioning.
• Utilize distributed storage systems like Hadoop or Spark to store and process large volumes of data across multiple nodes

• Implement data compression techniques such as gzip or snappy to reduce storage space and improve data transfer speeds

• Partition data into smaller chunks based on ke...read more

Q1. What are the concepts of quantum mechanics ?
Ans. 
Quantum mechanics is a branch of physics that deals with the behavior of particles at the atomic and subatomic levels.
• Quantum superposition - particles can exist in multiple states simultaneously until measured

• Quantum entanglement - particles become interconnected and can affect each other's properties even when separated by large distances

• Wave-particle duality - particles exhibit both wave-like and particle-like behav...read more

Q1. What is universal testing machine? What is gauge length?
Ans. 
A universal testing machine is a device used to test the mechanical properties of materials.
• It can measure properties such as tensile strength, compression strength, and elasticity.

• It works by applying a force to a sample and measuring the resulting deformation.

• Gauge length is the length of the section of the sample that is being tested.

• It is important to use the correct gauge length to ensure accurate test results.
