āš Interview Questions From This Project
Q1. What is TF-IDF?Ā
Answer: TF-IDF (Term Frequency-Inverse Document Frequency) is a statistical measure that evaluates the importance of a word in a document relative to a collection of documents (corpus). It increases proportionally to the number of times a word appears in the document but is offset by the frequency of the word in the corpus, helping to highlight words that are unique to specific documents.
Q2. What is Cosine Similarity?Ā
Answer: Cosine Similarity is a metric used to measure how similar two vectors are by calculating the cosine of the angle between them. In the context of text analysis, it quantifies how closely related two pieces of text are based on their vector representations. A cosine similarity closer to 1 indicates high similarity, while a value closer to 0 indicates low similarity.
Q3. Why use embeddings instead of keywords?Ā
Answer: Embeddings allow for a deeper understanding of text by capturing semantic meaning rather than relying solely on exact keyword matches. This means that related skills or concepts can be recognized even if different terminology is used, thereby improving the accuracy of candidate evaluations.

| 16 | š AI Project #3: Face Detection System Computer Vision Project
Welcome to your first Computer Vision project!
In this project, you'll teach a computer to identify human faces in images and live video streams.
This project introduces one of the most important AI domains:
š Computer Vision
Computer Vision enables machines to understand and analyze visual information from images and videos.
šÆ Project Goal
Build a Face Detection System that can:
ā
Detect faces in images
ā
Detect faces in videos
ā
Detect faces through webcam feed
ā
Draw bounding boxes around detected faces
š§ Skills You'll Learn
Python
Functions
Loops
File Handling
Computer Vision
OpenCV

AI Concepts
Face Detection
Object Detection
Real-Time Video Processing
Deployment
Streamlit
š Difference Between Face Detection & Face Recognition
Face Detection
Answers:
Is there a face in the image?
Example: Image 3 Faces Found
Face Recognition
Answers:
Whose face is it?
Example: Face Found John
This project focuses on:
ā
Face Detection
š Step 1: Install Required Libraries
pip install opencv-python
Verify Installation:
import cv2
print(cv2.__version__)
š¼ļø Step 2: Read an Image
import cv2
image = cv2.imread("person.jpg")
cv2.imshow("Image", image)
cv2.waitKey(0)
cv2.destroyAllWindows()
š Step 3: Convert Image to Grayscale
Face detection works better on grayscale images.
gray = cv2.cvtColor(
image,
cv2.COLOR_BGR2GRAY
)
Why?
ā
Faster processing
ā
Less memory usage
ā
Better detection performance
š¤ Step 4: Load Pre-Trained Face Detector
OpenCV provides a pre-trained Haar Cascade model.
face_cascade = cv2.CascadeClassifier(
cv2.data.haarcascades +
"haarcascade_frontalface_default.xml"
)
šÆ Step 5: Detect Faces
faces = face_cascade.detectMultiScale(
gray,
scaleFactor=1.1,
minNeighbors=5
)
What Happens Here?
The model scans the image and returns coordinates:
x = 120
y = 60
width = 180
height = 180
Each coordinate represents a detected face.
š„ Step 6: Draw Bounding Boxes
for (x,y,w,h) in faces:
cv2.rectangle(
image,
(x,y),
(x+w,y+h),
(255,0,0),
2
)
Output:
š Face Detected
āāāāāāāāāāāā
ā Face ā
āāāāāāāāāāāā
š„ļø Step 7: Display Result
cv2.imshow(
"Face Detection",
image
)
cv2.waitKey(0)
cv2.destroyAllWindows()
Now detected faces appear inside rectangles.
š„ Step 8: Real-Time Webcam Detection
This is where the project becomes exciting.
Access Webcam:
cap = cv2.VideoCapture(0)
š Step 9: Process Video Frames
while True:
success, frame = cap.read()
gray = cv2.cvtColor(
frame,
cv2.COLOR_BGR2GRAY
)
faces = face_cascade.detectMultiScale(
gray,
1.1,
5
)
for (x,y,w,h) in faces:
cv2.rectangle(
frame,
(x,y),
(x+w,y+h),
(255,0,0),
2
)
cv2.imshow(
"Face Detector",
frame
)
if cv2.waitKey(1) == 27:
break
Press: ESC to stop.
š Step 10: Release Camera
cap.release()

| 19 | š§ AI Project #2: Spam Email Detector with NLP
šÆ Project Goal
Build an AI app that reads any email text and tells you if itās Spam or Ham in 1 second.
Spam = unwanted/promotional mail. Ham = legit mail like āTeam meeting at 4 PMā.
š§ Skills Youāll Learn
Python: Strings, Functions, Lists
Data: Pandas, NumPy for dataset handling
NLP: Text cleaning, Tokenization, Stopwords, Stemming, TF-IDF
ML: Naive Bayes, Logistic Regression, Random Forest
Deployment: Streamlit for web app
š Step 1: Dataset
Typical format: 2 columns
Email Text | Label
"Win ā¹1 Lakh now, click here" | 1 ā Spam
"Project report attached" | 0 ā Ham
Label: 0 = Ham, 1 = Spam
š Step 2: Load & Explore Data
import pandas as pd
df = pd.read_csv("spam.csv")
print(df.head())
print(df['label'].value_counts())
Check: total emails, spam %, missing values.
š§¹ Step 3: Text Preprocessing
Raw: "Congratulations!!! You WON ā¹50,000... CLICK NOW!!!"
Clean: "congratulation won click"
Convert to lowercase
text = text.lower()
Remove punctuation
import string
text = text.translate(str.maketrans('', '', string.punctuation))
Step 4: Tokenization
Split sentence into words
"you won prize" ā ["you", "won", "prize"]
from nltk.tokenize import word_tokenize
tokens = word_tokenize(text)
Step 5: Remove Stopwords
Remove common words:
the, is, a, an
["you", "won", "the", "prize"] ā ["won", "prize"]
from nltk.corpus import stopwords
words = [w for w in tokens if w not in stopwords.words('english')]
Step 6: Stemming
Reduce words to root form
running, runs, ran ā run
playing, played ā play
from nltk.stem import PorterStemmer
ps = PorterStemmer()
words = [ps.stem(w) for w in words]
Step 7: Convert Text to Numbers with TF-IDF
ML models canāt read text. TF-IDF gives importance score to words.
Spam words like āwin, free, offerā get high scores.
from sklearn.feature_extraction.text import TfidfVectorizer
tfidf = TfidfVectorizer()
X = tfidf.fit_transform(df['text'])
Step 8: Train Model
from sklearn.linear_model import LogisticRegression
model = LogisticRegression()
model.fit(X_train, y_train)
Other models to try: Multinomial Naive Bayes, Random Forest, XGBoost
Step 9: Predict New Email
sample = ["Congratulations you won free iPhone"]
sample_vec = tfidf.transform(sample)
pred = model.predict(sample_vec)
print("Spam" if pred[0]==1 else "Ham")
Step 10: Check Performance
from sklearn.metrics import accuracy_score, precision_score, recall_score, confusion_matrix
print("Accuracy:", accuracy_score(y_test, y_pred))
Also check Precision, Recall, F1-Score, Confusion Matrix.
šØ Step 11: Build Streamlit App
import streamlit as st
st.title("Spam Email Detector")
email = st.text_area("Paste email text here")
if st.button("Check"):
email_vec = tfidf.transform([email])
result = model.predict(email_vec)
if result[0]==1:
st.error("šØ Spam Email Detected")
else:
st.success("ā
Legit Email")
Run: streamlit run app.py
