Machine Learning Model Implementation:
Train a Random Forest classifier on the original dataset and record its performance.
Use PCA to reduce the dataset's dimensionality to Train a new Random Forest classifier on the
reduced dataset and see how long it takes. Was training much faster? Then, evaluate the classifier on
the test set. How does it compare to the previous classifier?
Critical Evaluation and Conclusion:
Provide a comprehensive evaluation of the performance of the models.
Summarize findings and insights.
Research Question: Explore how various image preprocessing methods eg normalization, binarization,
noise reduction, and image augmentation influence the performance of at least two different machine
learning models eg Convolutional Neural Networks and Random Forest classifiers trained on the MNIST
dataset. Analyze the models' accuracy, training time, and ability to generalize to test data. Discuss your
findings' implications for designing machine learning pipelines in digit recognition tasks.
Reflect on the composition and diversity of the MNIST dataset, considering its impact on the training process
and model performance. Explore how the inclusion of a more diverse set of handwriting samples eg
different handwriting styles, inclusion of characters from nonLatin alphabets, or samples from wider age groups might affect the accuracy and generalizability of machine learning models trained for digit
recognition tasks. Instructions
MNIST number dataset a set of small images of digits handwritten by high school students and
employees of the US Cen sus Bureau. Each image is labeled with the digit it represents. This set has been
studied so much that it is often called the "hello world" of Machine Learning: whenever people come up with
a new classification algorithm they are curious to see how it will perform on MNIST, and anyone who learns
Machine Learning tackles this dataset sooner or later.
Instructions to explore this dataset are:
Data Acquisition and Initial Analysis:
Retrieve the MNIST dataset.
Perform exploratory data analysis to understand the dataset's structure, including
i how many images
ii how many features and the range of feature values eg histogram of the data value
relating it to realworld, such as real images.
iii. how many categorieslabels discrete or continuous type and what they are?
iv visualize at least three randomly selected samples within each category feel the variance
of the data
v visualize more data samples to see whether there are bad data samples need to be
removed. What bad data samples do you think can be
Data Preparation and Manipulation:
Apply dimensionality reduction techniques PCA and tSNE to the MNIST dataset and visualize the
results.
Split the dataset into training samples and testing samples sets.
