# Advanced Model Interpretation

# SHAP Values (Explainable AI)

import shap

# Train best model (Gradient Boosting)

best_model = gb.fit(x_train_scaled, y_train)

# SHAP analysis

explainer = shap.TreeExplainer(best_model)

shap_values = explainer.shap_values(x_test_scaled)

# Summary plot

shap.summary_plot(shap_values, x_test_scaled, feature_names=x.columns, plot_type="bar")

What’s Happening in This Code?

Let’s break it down like we’re analyzing a film’s key scenes:

Model Retraining:

best_model = gb.fit(x_train_scaled, y_train) retrains Gradient Boosting on the full scaled training set.

SHAP Setup:

explainer = shap.TreeExplainer(best_model) initializes a SHAP explainer optimized for tree-based models.
shap_values = explainer.shap_values(x_test_scaled) computes SHAP values for each feature’s contribution on the test set.

Summary Plot:

shap.summary_plot(shap_values, x_test_scaled, feature_names=x.columns, plot_type="bar") creates a bar plot showing the mean absolute SHAP value (average impact magnitude) for each feature.

The Output:

SHAP Summary Plot

Take a look at this image! The plot shows:

X-Axis: mean(|SHAP value|) (average impact on model output magnitude).
Y-Axis: Features (e.g., Adjusted Score, metascore, IMDB Rating, etc.).
Bars:

Adjusted Score: Highest impact (~12), dominating the predictions.
metascore: Moderate impact (~2-3).
IMDB Rating: Similar to metascore (~2-3).
Box Office Collection, Votes: Lower impact (~1-2).
Imdb_genre: Minimal impact (~0.5-1).

Insight: Adjusted Score is the primary driver, aligning with its 0.96 correlation with Score. Metascore and IMDB Rating contribute moderately, while Imdb_genre’s low impact suggests genre has limited influence, possibly due to encoding or data homogeneity.

Analysis:

Adjusted Score’s dominance confirms its strong predictive power, possibly due to its close tie to Score. We might consider using it as the sole feature or exploring its interaction with others.
metascore and IMDB Rating’s roles support their correlation findings (0.78 and 0.65), validating their importance.
The low impact of Imdb_genre and Votes suggests potential feature reduction to simplify the model.
This SHAP analysis enhances our trust in Gradient Boosting’s decisions.

This interpretability boost sets us up for optimization, let’s tune the model next!

Next Steps for Box Office Score Prediction

We’ve illuminated feature impacts with SHAP, stellar insight! Next, we’ll optimize Gradient Boosting with hyperparameter tuning using GridSearchCV or RandomizedSearchCV to elevate its R² further.

Peering Behind the Scenes: Residual Diagnostics in Part 2 of "Box Office Score Prediction Using AI" Project Blog!

So, my fellow cinephiles and coding virtuosos, we're taking a critical deep dive in Part 2 of our "Box Office Score Prediction Using AI" Project Blog

We’re zooming into the director’s chair on www.theprogrammarkid004.online harnessing the magic of artificial intelligence, machine learning, web development, and more to predict the "Score" from our captivating box office collection dataset. With Gradient Boosting leading the pack (R² 0.9657) and its feature impacts decoded via SHAP, we’re now analyzing residual diagnostics, exploring residuals vs. predicted values and checking normality with a Q-Q plot to ensure our model’s predictions are on point!

Why Residual Diagnostics Matter

Residual analysis helps us validate Gradient Boosting’s assumptions, ensuring residuals are randomly scattered (no patterns) and approximately normal, which confirms the model’s reliability for Score prediction.

What to Expect in This Step

In this step, we’ll:

Calculate residuals as the difference between actual and predicted values.
Create a Residual vs. Predicted plot to check for patterns.
Use a Q-Q plot to assess residual normality.

Get ready to diagnose, our journey is polishing the prediction!

Fun Fact:

Residual Analysis Roots!

Did you know residual diagnostics, pioneered by statisticians like Ronald Fisher in the 1920s, remain essential for model validation? Our plots carry forward this legacy!

Real-Life Example

Imagine you’re a data analyst predicting movie scores. Consistent residuals could mean our model is ready for studio use, let’s check!

Quiz Time!

Let’s test your diagnostic skills, students!

What do residuals represent?
a) Predicted values
b) Differences between actual and predicted values

Residual Diagnostics in Box Office Score Prediction

Here’s the code we’re working with:

# Prediction Error Analysis

# Residual Diagnostics

residuals = y_test - best_model.predict(x_test_scaled)

# Residual vs Predicted plot

plt.figure(figsize=(10, 6))

sns.scatterplot(x=best_model.predict(x_test_scaled), y=residuals)

plt.axhline(y=0, color='r', linestyle='--')

plt.title("Residuals vs Predicted Values")

plt.xlabel("Predicted Prices")

plt.ylabel("Residuals")

# Q-Q plot for normality check

import scipy.stats as stats

stats.probplot(residuals, dist="norm", plot=plt);

Output:

Residual Diagnostics Plots

The plot includes:

Residuals vs. Predicted Values:

A scatter of residuals (y-axis) against predicted values (x-axis).
The red dashed line at zero shows the ideal residual mean.
Insight: Residuals are scattered around zero with no clear pattern, though there’s a slight concentration below zero for lower predictions and above for higher ones, suggesting minor heteroscedasticity (non-constant variance).

Q-Q Plot:

Ordered values (y-axis) vs. theoretical quantiles (x-axis).
The red line represents the ideal normal distribution.
Insight: Points deviate from the line at the tails (e.g., below -5 and above 5), indicating residuals are not perfectly normal, with heavier tails than a normal distribution.

Analysis:

Residual Plot: The lack of a strong pattern is good, but the spread increases with predicted values, hinting at potential non-linearity or needing a transformation (e.g., log for Box Office Collection).
Q-Q Plot: The deviation at the tails suggests residuals are slightly leptokurtic (fat-tailed), which is common in real data but may affect model assumptions. A robust model like Gradient Boosting can handle this to some extent.
Implication: The model performs well overall (R² 0.9657), but these diagnostics suggest room for improvement, possibly through feature engineering or a different loss function.

This analysis guides our next moves. Let's optimize further!

Next Steps for Box Office Score Prediction

We’ve diagnosed the residuals, stellar scrutiny! Next, we’ll optimize Gradient Boosting with hyperparameter tuning using GridSearchCV or RandomizedSearchCV to address these residual patterns and boost performance.

rmse_dollars = np.sqrt(mean_squared_error(y_test, best_model.predict(x_test_scaled))) * 1000

print(f"Average Prediction Error: ${rmse_dollars:,.2f}")

# Compare to median house price

median_price = np.median(y_train) * 1000

print(f"Error as % of Median Price: {rmse_dollars/median_price:.2%}")

The Output:

Average Prediction Error: $3,414.04
Error as % of Median Price: 4.02%

Monetary Impact

Average Prediction Error: $3,414.04
Error as % of Median Price: 4.02%
Insight:
Average Prediction Error: $3,414.04 represents the typical error in predicting a movie’s score, interpreted as a $3,414 deviation in a $1,000-unit score.
Error as Percentage: 4.02% of the median score (assuming median y_train is around 84,900 in $1,000 units) indicates the error is relatively small compared to the typical score.
Business Implication:
A $3,414 error is modest for high-budget films (e.g., $100M+), suggesting the model is reliable for broad predictions.
The 4.02% relative error is acceptable for strategic planning, but studios might aim for lower errors (<2%) for precise budgeting.
Context: Given the wide range of Box Office Collection (millions to hundreds of millions), this error aligns with the model’s R² of 0.9657, though feature scaling or outlier handling could refine it.
This business insight highlights the model’s practical value, let’s optimize it next!

Cross-Validated Predictions in Box Office Score Prediction
Here’s the code we’re working with:

from sklearn.model_selection import cross_val_predict

# Get cross-val predictions with uncertainty
predictions = cross_val_predict(best_model, x_train_scaled, y_train, cv=5, method="predict")

# Plot actual vs predicted with 95% CI
sns.regplot(x=y_train, y=predictions)
plt.title("Cross-Validated Predictions")
The Output:

Cross-Validated Predictions Plot
The plot shows:
X-Axis: Actual Score values (y_train) ranging from 0 to 100.
Y-Axis: Predicted Score values (predictions) ranging from 0 to 100.
Regression Line: A blue line with a slope close to 1, indicating a strong linear relationship.
Data Points: Blue dots representing individual predictions, clustered along the line.
95% CI: The shaded area around the line (not fully visible due to scale) suggests the uncertainty range.
Insight: The tight clustering along the diagonal line (y = x) reflects a high R² (consistent with 0.9657), with most predictions aligning closely with actual scores. The slight spread at higher values (80-100) hints at minor over- or under-prediction, but the overall fit is excellent.
Analysis:
Fit Quality: The near-linear alignment confirms Gradient Boosting’s strong predictive power, supporting the R² of 0.9657 and cross-val mean of 0.9719.
Confidence Interval: The tight CI (implied by the dense clustering) indicates low uncertainty, reinforcing model reliability.
Potential Improvement: The slight deviation at higher scores suggests possible refinement (e.g., tuning or feature engineering) to capture outliers better.
Implication: This plot validates the model’s consistency across folds, making it a trustworthy tool for studios.
This cross-validation boost sets us up for optimization, let’s tune it next!
