An Artificial Neuron Network (ANN), popularly known as Neural Network is a computational model based on the structure and functions of biological neural networks. It is like an artificial human nervous system for receiving, processing, and transmitting information in terms of Computer Science.
Basically, there are 3 different layers in a neural network :
Input Layer (All the inputs are fed in the model through this layer)
Hidden Layers (There can be more than one hidden layers which are used for processing the inputs received from the input layers)
Output Layer (The data after processing is made available at the output layer)
Graph data can be used with a lot of learning tasks contain a lot rich relation data among elements. For example, modeling physics system, predicting protein interface, and classifying diseases require that a model learns from graph inputs. Graph reasoning models can also be used for learning from non-structural data like texts and images and reasoning on extracted structures.

Breaking into Data Science doesn’t need to be complicated.
If you’re just starting out,
Here’s how to simplify your approach:
Avoid:
🚫 Trying to learn every tool and library (Python, R, TensorFlow, Hadoop, etc.) all at once.
🚫 Spending months on theoretical concepts without hands-on practice.
🚫 Overloading your resume with keywords instead of impactful projects.
🚫 Believing you need a Ph.D. to break into the field.
Instead:
✅ Start with Python or R—focus on mastering one language first.
✅ Learn how to work with structured data (Excel or SQL) - this is your bread and butter.
✅ Dive into a simple machine learning model (like linear regression) to understand the basics.
✅ Solve real-world problems with open datasets and share them in a portfolio.
✅ Build a project that tells a story - why the problem matters, what you found, and what actions it suggests.

Data-Driven Decision Making
Data-driven decision-making (DDDM) involves using data analytics to guide business strategies instead of relying on intuition. Key techniques include A/B testing, forecasting, trend analysis, and KPI evaluation.
1️⃣ A/B Testing & Hypothesis Testing
A/B testing compares two versions of a product, marketing campaign, or website feature to determine which performs better.
✔ Key Metrics in A/B Testing:
Conversion Rate
Click-Through Rate (CTR)
Revenue per User
✔ Steps in A/B Testing:
1. Define the hypothesis (e.g., "Changing the CTA button color will increase clicks").
2. Split users into Group A (control) and Group B (test).
3. Analyze differences using statistical tests.
✔ SQL for A/B Testing:
Calculate average purchase per user in two test groups
SELECT test_group, AVG(purchase_amount) AS avg_purchase
FROM ab_test_results
GROUP BY test_group;{}
Run a t-test to check statistical significance (Python)
from scipy.stats import ttest_ind
t_stat, p_value = ttest_ind(group_A['conversion_rate'], group_B['conversion_rate'])
print(f"T-statistic: {t_stat}, P-value: {p_value}"){}
🔹 P-value < 0.05 → Statistically significant difference.
🔹 P-value > 0.05 → No strong evidence of difference.
2️⃣ Forecasting & Trend Analysis
Forecasting predicts future trends based on historical data.
✔ Time Series Analysis Techniques:
Moving Averages (smooth trends)
Exponential Smoothing (weights recent data more)
ARIMA Models (AutoRegressive Integrated Moving Average)
✔ SQL for Moving Averages:
7-day moving average of sales
SELECT order_date,
sales,
AVG(sales) OVER (ORDER BY order_date ROWS BETWEEN 6 PRECEDING AND CURRENT ROW) AS moving_avg
FROM sales_data;{}
✔ Python for Forecasting (Using Prophet)
from fbprophet import Prophet
model = Prophet()
model.fit(df)
future = model.make_future_dataframe(periods=30)
forecast = model.predict(future)
model.plot(forecast){}
3️⃣ KPI & Metrics Analysis
KPIs (Key Performance Indicators) measure business performance.
✔ Common Business KPIs:
Revenue Growth Rate → (Current Revenue - Previous Revenue) / Previous Revenue
Customer Retention Rate → Customers at End / Customers at Start
Churn Rate → % of customers lost over time
Net Promoter Score (NPS) → Measures customer satisfaction
✔ SQL for KPI Analysis:
Calculate Monthly Revenue Growth
SELECT month,
revenue,
LAG(revenue) OVER (ORDER BY month) AS prev_month_revenue,
(revenue - prev_month_revenue) / prev_month_revenue * 100 AS growth_rate
FROM revenue_data;{}
✔ Python for KPI Dashboard (Using Matplotlib)
import matplotlib.pyplot as plt
plt.plot(df['month'], df['revenue_growth'], marker='o')
plt.title('Monthly Revenue Growth')
plt.xlabel('Month')
plt.ylabel('Growth Rate (%)')
plt.show(){}
4️⃣ Real-Life Use Cases of Data-Driven Decisions
📌 E-commerce: Optimize pricing based on customer demand trends.
📌 Finance: Predict stock prices using time series forecasting.
📌 Marketing: Improve email campaign conversion rates with A/B testing.
📌 Healthcare: Identify disease patterns using predictive analytics.
Mini Task for You: Write an SQL query to calculate the customer churn rate for a subscription-based company.
