Ensure proper documentation for the new parameter.

The new parameter overwrite_cache_filtered_task should be included in the function's docstring to maintain comprehensive documentation.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

to ``"timestamp"``). This is to avoid needing to load the full dataset in flattened form into
memory. This is also used as a cache key; if a pre-filtered dataset is written to disk at a
specified path for this task, then the data will be loaded from there, rather than from the base
dataset.

Tip

Codebase Verification

Ensure all calls to load_flat_rep include the new parameter overwrite_cache_filtered_task.

The following calls to load_flat_rep in sample_data/examine_synthetic_data.ipynb do not include the new parameter and should be updated:

  • flat_reps = load_flat_rep(ESD, window_sizes=['7d'])
  • flat_reps = load_flat_rep(ESD, window_sizes=['FULL'], feature_inclusion_frequency=0.001)
  • flat_reps = load_flat_rep(ESD, window_sizes=['1d', '7d', 'FULL'])
  • flat_reps = load_flat_rep(ESD, window_sizes=['2d'], do_update_if_missing=False)
  • flat_reps = load_flat_rep(ESD, window_sizes=['1d', '7d', 'FULL'], subjects_included={'train': {0, 1, 2}})
  • flat_reps = load_flat_rep(ESD, window_sizes=['7d'], task_df_name='single_label_binary_classification')
  • flat_reps = load_flat_rep(ESD, window_sizes=['FULL', '1d'], task_df_name='multi_class_classification', do_cache_filtered_task=False)
  • flat_reps = load_flat_rep(ESD, window_sizes=['FULL', '1d'], task_df_name='single_label_binary_classification', subjects_included={'train': {0, 1, 2}})

Please update these calls to include the overwrite_cache_filtered_task parameter as needed.

Analysis chain

LGTM! But verify the new parameter usage in the codebase.

The code changes are approved.

However, ensure that all function calls to load_flat_rep are updated to use the new parameter if necessary.

Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Verify all function calls to `load_flat_rep` match the new signature.

# Test: Search for the function usage. Expect: Only occurrences of the new signature.
rg --type python $'load_flat_rep'

Length of output: 63

Script:

#!/bin/bash
# Description: Verify all function calls to `load_flat_rep` match the new signature.

# Test: Search for the function usage. Expect: Only occurrences of the new signature.
rg 'load_flat_rep'

Length of output: 1215

Script:

#!/bin/bash
# Description: Extract lines around each call to `load_flat_rep` to verify the usage of the new parameter.

# Extract lines around the calls in the Jupyter notebook
rg -A 3 -B 3 'load_flat_rep' sample_data/examine_synthetic_data.ipynb

# Extract lines around the calls in the Python file
rg -A 3 -B 3 'load_flat_rep' EventStream/baseline/FT_task_baseline.py

Length of output: 3273

subjects_included: A dictionary by split of the subjects to include in the task. Omitted splits are
used wholesale.
