## Suggestions for complexity 1. **Dynamic Beta Adjustment**: Introduce logic to dynamically adjust `beta` based on real-time performance metrics or other external factors during computation.
2. **Multiclass Support**: Extend the function from binary classification to multiclass classification while maintaining backward compatibility.
3. **Custom Warning Messages**: Allow users to define custom warning messages for different types of undefined scores based on `warn_for`.
4. **Parallel Computation**: Implement parallel processing within conditional checks for `tp_sum`, `fp_sum`, etc., to optimize performance on large datasets.
5. **Custom Aggregation Functions**: Enable users to pass custom aggregation functions instead of standard averaging methods like 'binary', 'micro', etc., providing more flexibility. ## Conversation <|user|>Hello AI I need help with some code snippet I have [SNIPPET]<|end|> <|assistant|>Sure! How can I assist you with this snippet? It looks like it involves computing various metrics like precision, recall, f-beta score using conditional checks.<|end|> <|user|>I want beta value change dynamically based on some performance metric during computation how do i do that<|end|> <|assistant|>To dynamically adjust `beta` based on performance metrics during computation, we can introduce an internal function that recalculates `beta` at each step based on your chosen metric. For example: python
def dynamic_beta(tp_sum, fp_sum):
# Example logic for adjusting beta based on tp_sum / fp_sum ratio
if fp_sum ==0:
return float('inf')
return tp_sum / fp_sum def precision_recall_fscore_support(y_true,
y_pred,
beta=1,
labels=None,
pos_label=1,
average='binary',
warn_for=('precision', 'recall', 'f-score'),
sample_weight=None):
# Other existing code...
# Inside your conditional checks:
if tp_sum + fp_sum == zero_condition:
beta = dynamic_beta(tp_sum, fp_sum)
# Use updated beta value for further calculations
# Continue with existing computations... This way `beta` will be recalculated dynamically based on `tp_sum` and `fp_sum`. You can adjust `dynamic_beta` logic according to your specific needs.<|end|> <|user|>ok but what if i want it multiclass support now also still binary<|end|> <|assistant|>To extend this function from binary classification to multiclass classification while maintaining backward compatibility with binary classification requires adding logic that checks if multiclass mode is enabled: python
def precision_recall_fscore_support(y_true,
y_pred,
beta=1,
labels=None,
pos_label=1,
average='binary',
warn_for=('precision', 'recall', 'f-score'),
sample_weight=None):
def compute_tp_fp_tn_fn(y_true_bin, y_pred_bin):
tp = ((y_true_bin == pos_label) & (y_pred_bin == pos_label)).sum()
tn = ((y_true_bin != pos_label) & (y_pred_bin != pos_label)).sum()
fp = ((y_true_bin != pos_label) & (y_pred_bin == pos_label)).sum()
fn = ((y_true_bin == pos_label) & (y_pred_bin != pos_label)).sum()
return tp, tn, fp, fn
if labels is None:
labels = np.unique(np.concatenate((y_true, y_pred)))
n_labels = len(labels)
else:
n_labels = len(labels) if average == 'binary':
# Binary mode logic as before...
pass
elif average in ('micro', 'macro', 'weighted'):
# Multiclass mode logic
precisions = []
recalls = []
fbeta_scores = []
supports = []
for label in labels:
y_true_bin = (y_true == label)
y_pred_bin = (y_pred == label)
tp, tn, fp, fn = compute_tp_fp_tn_fn(y_true_bin, y_pred_bin)
support = len(y_true_bin)
precision = tp / (tp + fp) if tp + fp > zero_condition else zero_division_value
recall = tp / (tp + fn) if tp + fn > zero_condition else zero_division_value
fbeta_score = ((1 + beta**2) * precision * recall /
(beta**2 * precision + recall)) if precision + recall > zero_condition else zero_division_value
precisions.append(precision)
recalls.append(recall)
fbeta_scores.append(fbeta_score)
supports.append(support)
# Dynamic beta adjustment here if needed
# Aggregating results based on average method... This approach introduces additional logic for multiclass support while retaining existing binary functionality.<|end|> <|user|>great now how can i add custom warning messages when undefined scores happen<|end|> <|assistant|>To add custom warning messages when undefined scores happen based on `warn_for`, we can define a dictionary that maps score types to custom messages: python
def precision_recall_fscore_support(y_true,
y_pred,
beta=1,
labels=None,
pos_label=1,
average='binary',
warn_for=('precision', 'recall', 'f-score'),
sample_weight=None):
custom_warnings = {
'precision': "Warning: Precision is undefined.",
'recall': "Warning: Recall is undefined.",
'f-score': "Warning: F-beta score is undefined."
} def warn(score_type):
if score_type in custom_warnings:
print(custom_warnings[score_type])
def compute_tp_fp_tn_fn(y_true_bin, y_pred_bin):
tp = ((y_true_bin == pos_label) & (y_pred_bin == pos_label)).sum()
tn = ((y_true_bin != pos_label) & (y_pred_bin != pos_label)).sum()
fp = ((y_true_bin != pos_label) & (y_pred_bin == pos_label)).sum()
fn = ((y_true_bin == pos_label) & (y_pred_bin != pos_label)).sum()
return tp, tn, fp, fn
if labels is None:
labels = np.unique(np.concatenate((y_true, y_pred)))
n_labels = len(labels)
else:
n_labels = len(labels) if average == 'binary':
# Binary mode logic as before...
tp_sum += compute_tp_fp_tn_fn(...)
fp_sum += ...
if warn_for in ('precision',) and tp_sum + fp_sum == zero_condition:
warn('precision')
precision = zero_division_value
if warn_for in ('recall',) and tp_sum + fn_sum == zero_condition:
warn('recall')
recall = zero_division_value
if warn_for in ('f-score',) and precision + recall == zero_condition:
warn('f-score')
fbeta_score = zero_division_value
# Continue existing computations... With this setup:
- You can customize warnings by updating `custom_warnings`.
- The function will print warnings whenever an undefined score condition occurs based on `warn_for`. Would you like further customization or assistance?
