Just completed the ML Zoomcamp 2024 Competition on kaggle which is a Retail Demand Forecasting Challenge! The competition challenges participants to forecast customer demand based on historical sales and related data from a retailer.

The dataset consists of 10 files in csv format with a total size of 872.28 MB and the files had to be aggregated to form a single dataset of 7,432,685 rows, and 16 columns.

Creating a model for this dataset was a challenge because the size was to large for all the platforms I used so, I have to apply an ensemble method where a fraction of the date was modelled in series and later combined at the end.

This was a wonderful experience that was much more different from the toy dataset that we are used to.

ML Zoomcamp Project Capstone 3 – 3: First trainings

After conducting the exploratory data analysis, 3 pre-trained deep convolutional neural network models were used to train the data for 10 epochs each with the aim of finding the one that will return the best test accuracy which will then be used to create the final model. The results obtained with BATCH_SIZE = 32, LEARNING_RATE = 0.0001 are shown below:

Xception - 98.93%

InceptionV3 - 98.32%

ResNet101V2 - 96.80%

Xception was selected because of its higher test accuracy. Attached is the full output of the trainings.

ML Zoomcamp Project Capstone 2 – 2: Exploratory Data Analysis

The dataset used in this project is the Brain Tumor MRI Dataset https://www.kaggle.com/datasets/masoudnickparvar/brain-tumor-mri-dataset from kaggle.

It consists of 7,023 magnetic resonance imaging scans, annotated in a folder structure of 5,712 test and 1,311 train. The dataset consists of images of no tumour and brain tumor types: pituitary, meningioma, and glioma, as shown in the attached diagram.

ML Zoomcamp Project Capstone 2 – 1: Problem Statement

A brain tumor is a mass of abnormal cells that grows in the brain, it can be benign (non-cancerous) or malignant (cancerous). Its symptoms are:

Headaches, which can be severe, persistent, or come and go

Seizures, which can be mild or severe

Weakness or paralysis in part of the body

Loss of balance

Changes in mood or personality

Changes in vision, hearing, smell, or taste

Nausea and vomiting

Difficulty speaking

Difficulty swallowing

The growth of brain tumors can cause the pressure inside the skull to increase leading to brain damage, and loss of life if not discovered early and properly treated.

This project is aimed at developing a robust brain tumor detection model using Convolutional Neural Networks (CNNs) to automate the analysis of magnetic resonance imaging (MRI) scan by accurately identifying and classifying the tumors at an early stage which can reduce the load on doctors, help in selecting the most convenient treatment method and hence increase the rate of survival.
