TITANIC DATASET

-

The data includes demographic and travel information for 1,309 Titanic passengers to predict their survival. The whole Titanic dataset is accessible in multiple forms from the Department of Biostatistics at Vanderbilt University School of Medicine (http://biostat.mc.vanderbilt.edu/wiki/pub/Main/DataSets/titanic3.csv). The go-to resource for information about the Titanic is the website for Encyclopaedia Titanica (https://www.encyclopedia-titanica.org/). It includes a complete list of the passengers and crew and all the relevant information on the Titanic's facts, history, and data. Additionally, the Titanic dataset is the focus of the inaugural competition on Kaggle.com (https://www.kaggle.com/c/titanic; needs creating a Kaggle account). Additionally, a CSV version is available in the GitHub repository at https://github.com/alexperrier/packt-aml/blob/master/ch4.

survivalSurvival0 = No, 1 = Yes

Variable Notes

pclass: A proxy for socio-economic status (SES)
1st = Upper
2nd = Middle
3rd = Lower

age: Age is fractional if less than 1. If the age is estimated, is it in the form of xx.5

sibsp: The dataset defines family relations in this way...
Sibling = brother, sister, stepbrother, stepsister
Spouse = husband, wife (mistresses and fiancés were ignored)

parch: The dataset defines family relations in this way...
Parent = mother, father
Child = daughter, son, stepdaughter, stepson
Some children travelled only with a nanny, therefore parch=0 for them.


Questions:

1. Identify the male and female count in the dataset and draw a graph using Excel and Python
2. Identify the male and female court based on age and draw a graph using Excel and Python
3. Identify the P-class types in that how many males and females count draw a graph using Excel and Python
4. Identify the P-class types in that how many males and females count according to survivals draw a graph using Excel and Python

USING SEABORN

# Group passengers by Sex and count the occurrences

sex_counts.columns = ['Sex', 'Count']


# Define a color palette

colors = sns.color_palette("pastel")


# Plotting the data with color palette

ax = sns.barplot(x='Sex', y='Count', data=sex_counts, palette=colors)

plt.title('Count of Males and Females')

plt.xlabel('Sex')

plt.ylabel('Count')

 

# Annotate count numbers on the bars

for p in ax.patches:

A set of documents that need to be classified, use the Naive Bayesian Classifier

-
The Naive Bayes Classifier is a probabilistic machine learning model widely used for classification tasks, including document classification. Based on Bayes' Theorem, it assumes that the features (in this case, words or terms in the documents) are conditionally independent given the class label. Despite this "naive" assumption, it often performs well in practice, especially for text classification. Steps to Perform Document Classification Using Naive Bayes 1.  Prepare the Dataset Documents : Assume you have a set of documents, each labeled with a category (e.g., "Sports", "Politics", "Technology"). Preprocessing : Tokenize the text into words. Remove stop words (e.g., "the", "is", "and"). Perform stemming or lemmatization to reduce words to their base forms. Convert text into a numerical representation, such as a  bag-of-words  or  TF-IDF  vector. 2.  Split the Dataset Divide the dataset into a  training set  and...

  Understanding Keras Models: Your Neural Network Blueprint Think of a Keras model as the blueprint or architecture for building neural networks. Keras is designed to be simple and lets you create models quickly, while running on powerful engines like TensorFlow in the background. The Three Ways to Build a Keras Model 1. Sequential API: The Straightforward Stack What it is: The easiest way to build a model, like stacking Lego blocks in a single, straight line. Best for: Standard networks where data flows directly from one layer to the next with no fancy detours. Limitation: It's too rigid for complex designs that need multiple inputs, outputs, or layers that share connections. 2. Functional API: The Flexible Designer What it is: A more powerful approach that lets you create complex, branch-like architectures. Best for: Advanced designs with multiple inputs/outputs, skip connections (like shortcuts in the network), or layers that are shared. Example: Building sophisticated models li...
