  EDA in Data Analytics: What is EDA in data analytics? " EDA stands for Exploratory Data Analysis, and it is a crucial step in the data analytics process. EDA involves examining and summarizing data sets to gain insights, discover patterns, and identify relationships among variables. The main objective of EDA is to understand the data and its underlying structure before applying more advanced analysis techniques." During EDA, analysts employ various statistical and visualization techniques to explore the data. Some common techniques include: Summary statistics: Calculating measures such as mean, median, mode, standard deviation, and quartiles to understand the central tendency, spread, and distribution of the data. Data visualization: Creating charts, graphs, and plots to visualize the data, including histograms, scatter plots, box plots, and heatmaps. Visualizations help in identifying patterns, outliers, and relationships between variables. Data cleaning: Identifying and...

Curriculum Development : The HEC works on developing and updating curricula to align them with international standards and industry requirements. The aim is to produce graduates who possess relevant skills and knowledge for the job market. Research Promotion : The HEC encourages research and innovation in higher education i...

♻What is Genetic algorithm? " A genetic algorithm is a computer-based optimization technique that is inspired by the process of natural selection in biology. It starts with a population of potential solutions to a problem and evolves this population over several iterations to find the best solution. The algorithm uses concepts like selection, crossover, and mutation to simulate the evolutionary process. By doing so, it can efficiently search through a large number of possible solutions and find an optimal or near-optimal answer to the problem ." ♻Example og genetic algorithm: Let's say we want to find the maximum value of the function f(x) = x^2 in the range [0, 31]. We'll use a binary representation for the individuals in the population, where each individual is a string of binary digits representing a possible value for x. ➡Initialization : Generate an initial population of N individuals (random binary strings) with a fixed length L. Evaluate the fitness of each in...

 🍁 What is Pakistan stock exchange? ☣The Pakistan Stock Exchange (PSX) is the main stock exchange in Pakistan.
