The dataset contains 5643 images taken from a blood smear workflow (where a drop of blood is placed on a glass slide). The cells are parasitized or uninfected with malaria.

As a Data Analyst from Code Institute Consulting, you are requested by the Health Care division to provide actionable insights and data-driven recommendations to a Global Hospital Institution. The client is currently facing challenges in disease detection, especially with malaria.

• 1 - The client is interested in having a study to differentiate a parasitized and uninfected cell visually.
• 2 - The client is interested to tell whether a given cell contains malaria parasite or not.

• We suspect malaria parasitized cells have clear marks/signs, typically in the middle of the cell, differentiating them from uninfected cells.
  • A average image study can help to investigate it

• Business Requirement 1: Data Visualization

  • We will display the "mean" and "standard deviation" images for parasitized and uninfected cells.
  • We will display the difference between an average parasitized cell and an average uninfected cell.
  • We will display a image montage for either parasitized or uninfected cells.

• Business Requirement 2: Classification

  • We want to predict if a given cell is infected or not with malaria.
  • We want to build a binary classifier and generate reports.

• We want a ML model to predict if a cell is infected with malaria or not, based on historical image data. It is a supervised model, a 2-class, single-label, classification model.
• Our ideal outcome is provide the medical team a faster and reliable diagnostic if a given cell is infected or not with malaria.
• The model success metrics are
  • Accuracy of 65% or above on the test set.
• The model output is defined as a flag, indicating if the cell has malaria or not and the associated probability of being infected or not. The medical staff will do the blood smear workflow as usual and upload the picture to the App. The prediction is made on the fly (not in batches).
• Heuristics: The current diagnostic needs an experienced staff and detailed inspection to distinguish infected and not infected cells. A blood smear sample is collected, mixed with a reagent and examined under the microscope. Visual criteria are used to detect malaria parasites. It leaves room to produce inaccurate diagnostics due to human errors. On top of that, some specific hospital facilities with malaria centers don't have sufficient, proper staff and expertise and are typically understaffed.
• The training data to fit the model come from National Institutes of Health (NIH) Website. This dataset contains about 26+ thousand images. We have extracted a subset of 5643 images from this dataset and saved it to kaggle dataset directory for quicker model training.
  • Train data - target: infected or not; features: all images

• Quick project summary
  • General Information
    • Malaria is a parasitic infection transmitted by the bite of infected female Anopheles mosquitoes.
    • A blood smear sample is collected, mixed with a reagent and examined in the microscope. Visual criteria are used to detect malaria parasites.
    • According to WHO, in 2019, there were an estimated 229 million cases of malaria worldwide and an estimated 409 thousand deaths due to this diseease. Children <5 years are the most vulnerable group, accounting for 67% (274 thousand) of all malaria deaths worldwide in 2019.
  • Project Dataset
    • The available dataset contains 5643 out of +27 thousand images taken from blood smear workflow (when a drop of blood it taken on a glass slide) of cells that are parasitized or uninfected with malaria.
