Difference Between Data Science and Artificial Intelligence

In the current fast paced world where innovation in technology is the main focus two fields are mostly considered to have significant impacts. These are: "Data Science and Artificial Intelligence". Obviously, both of them are related to the concept of data, but their primary functions are dissimilar. Data Science deals with finding patterns in data for inference for problem solving whereas Artificial Intelligence makes use of that data for developing smart systems.

So let's define both concepts and then we will see how we can compare "Data Science and Artificial Intelligence" in terms of their essential components to figure out how they are used and how they function on their own.

What is Data Science?

Data Science - the process of gaining and making substantial insights from structured and unstructured data. It assists different companies and organizations in making correct conclusions concerning tendencies and patterns inside of it.

Data Science involves two main types of data:

1. Quantitative data: This is number, like one two three as the number of local clients acquired in a given period.

2. Qualitative data: This could be text, images or anything that is not actually a number or anything that is not actually a numerical value.

A Data Scientist's job typically involves:

• Data gathering work from different sources, which can be in paper/online format or by interview, etc.
• Cleansing and processing to make it correct.
• Applying the quantitative analysis in order to identify patterns that are concealed within the data.
• Analyzing the findings to make nearer sense and pass on the result.
• Presenting those insights using those graphical items such as the coordinate planes, charts, and reports. For example: If a retail business is witnessing lowest sales then Data Scientist will investigate if the issue is seasonal or concerning the change in customer trends.

Example 1: Analyzing Sales Data:

import pandas as pd
import matplotlib.pyplot as plt

# Sample data
data = {
    'Month': ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'],
    'Sales': [1200, 1500, 1700, 1600, 1800, 1900, 2000, 2100, 2200, 2300, 2400, 2500]
}

# Create DataFrame
df = pd.DataFrame(data)

# Plotting sales data
plt.figure(figsize=(10, 6))
plt.plot(df['Month'], df['Sales'], marker='o', linestyle='-', color='b')
plt.title('Monthly Sales Data')
plt.xlabel('Month')
plt.ylabel('Sales ($)')
plt.grid(True)
plt.xticks(rotation=45)
plt.tight_layout()
plt.show()

Output

A line chart displaying sales trends throughout the year.

Example 2: Customer Segmentation

import pandas as pd
from sklearn.cluster import KMeans

# Sample data
data = {
    'CustomerID': [1, 2, 3, 4, 5],
    'TotalSpend': [500, 1500, 3000, 2500, 4000],
    'Frequency': [10, 20, 30, 25, 35]
}

# Create DataFrame
df = pd.DataFrame(data)

# KMeans clustering
kmeans = KMeans(n_clusters=2, random_state=0).fit(df[['TotalSpend', 'Frequency']])
df['Cluster'] = kmeans.labels_

print(df)

Output

A Data-Frame with an additional Cluster column showing customer segments.

   CustomerID  TotalSpend  Frequency  Cluster
0           1         500         10        1
1           2        1500         20        1
2           3        3000         30        0
3           4        2500         25        0
4           5        4000         35        0

What is Artificial Intelligence?

Artificial Intelligence is all about designing sophisticated machines or systems, which can perform tasks that, if accomplished, would have required intelligent to do it. Such tasks may for instance be: recognition of voices or images or decision making in a matter of course.

The style is known as "Machine Learning (ML)"centered with the AI and it has the capacity of improving the speed of the machines as the implementation of the devices goes on learning from the data provided to the machines. Deep Learning, a more developed branch of AI, tries to replicate the example of working of human brain using neural networks to identify rather complex patterns, from an enormous amount of data.

Appliactions

Some common applications of AI include:

• Smart assistants: like "Siri" or even Alexa devices that, overhearing, people's voice, act in response to it.
• Security system: face detection algorithms or in the most loved social app.
• Self-driving cars: that can only navigate based on relatively cheap artificial intelligence to enable real decisions to be made on the spot.

Example 1: Simple Linear Regression

from sklearn.linear_model import LinearRegression
import numpy as np

# Sample data
X = np.array([[1500], [1800], [2200], [2500], [2700]])
y = np.array([300000, 350000, 400000, 450000, 500000])

# Create and train the model
model = LinearRegression().fit(X, y)

# Predict house price for a new size
new_size = np.array([[2600]])
predicted_price = model.predict(new_size)

print(f"Predicted price for 2600 sqft house: ${predicted_price[0]:,.2f}")

Output

Predicted price for a house of 2600 square feet.

Predicted price for 2600 sqft house: $473,353.91

Example 2: Image Classification with a Pre-trained Model

Image used in the following Python program

image source: pixelbay

Python Program

from tensorflow.keras.applications import VGG16
from tensorflow.keras.preprocessing import image
from tensorflow.keras.applications.vgg16 import preprocess_input, decode_predictions
import numpy as np

# Load pre-trained VGG16 model
model = VGG16(weights='imagenet')

# Load and preprocess an image
img_path = 'path_to_image.jpg'  # Replace with your image path
img = image.load_img(img_path, target_size=(224, 224))
img_array = image.img_to_array(img)
img_array = np.expand_dims(img_array, axis=0)
img_array = preprocess_input(img_array)

# Predict the class
predictions = model.predict(img_array)
decoded_predictions = decode_predictions(predictions, top=3)[0]

print(f"Predictions: {decoded_predictions}")

Output

Classifications for the provided image, including probabilities and labels.

Predictions: [('n02123159', 'tiger_cat', 0.35890165), ('n02124075', 'Egyptian_cat', 0.29482183), ('n02123045', 'tabby', 0.2883259)]

Conclusion

However, Data Science and Artificial Intelligence, two of the most similar sciences because they both operate with (data), are oriented to different goals. Data Science could be described as the analysis of data with specific intention of assisting decision making within the organizations. On the other, AI may be taken to mean the processes of designing and engineering of machines/systems on ones own to accomplish tasks without help from human beings. In sum, all these fields put together are transforming the appearance of the business environment today and are thus relevant in today's world that revolves around technology.
