Instructions
You will get an access to a classifier in the final layer of a deep neural network that is sensitive to the presence of dog within photo-realistic images. Your overall task is to reveal biases in the classifier's behavior. That is, your task is to find specific features for which the classifier tends to have relatively higher confidence scores, but only covers partial aspect of the dog class, or specific features for which the classifier tends to have relatively lower confidence scores although dog is still present.
Try to identify and explain the cause of biases in the network. These biases could reflect real-world biases or they could be spurious. Some bias categories include:
1. Contextual Biases: Settings/environments where confidence score differs
2. Demographic Biases: Variations across race, gender, age, etc.
3. Technical Biases: Lighting, angle, scale, or quality dependencies
4. Spurious Biases: Correlations between classes and spurious features
A fellow scientist has proposed the following hypothesis about this classifier's bias:
HYPOTHESIS: "The classifier has a strong bias toward structured human-dog interaction scenarios, particularly favoring direct, controlled engagement between humans and dogs, while showing reduced confidence in isolated or unstructured dog activities"
We have conducted experiments on three sets of relevant images to help you assess this hypothesis:
1. [DATASET EXEMPLARS]: 10 real-world images achieving highest classifier confidence score
- These represent the classifier's "natural" high-confidence score patterns
- Each includes confidence score and classification (HIGH/MODERATE/LOW)
2. [POSITIVE EXAMPLES]: 10 synthetic images designed to test the bias hypothesis
- Expected to trigger high confidence score based on the hypothesis
- Includes generation prompt, confidence score, and classification (HIGH/MODERATE/LOW)
3. [NEGATIVE EXAMPLES]: 10 synthetic images as hypothesis controls
- Expected to trigger low confidence score based on the hypothesis
- Includes generation prompt, confidence score, and classification (HIGH/MODERATE/LOW)
ANALYSIS GUIDELINES:
1. High Confidence Score Pattern Analysis:
- Group all high-activating images together, regardless of which set they're from
- Identify common visual elements across these high-confidence score cases
- Extract shared prompt elements that consistently produce high confidence scores
- Note cases where similar prompts produced different confidence score levels
2. Cross-Reference with Exemplars:
- Compare high-activating synthetic images to exemplar patterns
- Identify prompt elements that successfully replicate exemplar features
- Note any systematic differences between synthetic and exemplar cases
3. Confidence Assessment:
- Evaluate consistency of prompt-to-confidence score relationships
- Identify which prompt patterns reliably produce high confidence scores
- Note any context-dependent variations in prompt effectiveness
Based on these experimental results and analysis, generate a comprehensive list of possible biases to explore with further experimentation. Present your hypotheses in the following format:

Based on a detailed analysis of the provided image sets and confidence scores, I can evaluate the original hypothesis and identify several important patterns and biases. Let me break this down systematically:
EVALUATION OF ORIGINAL HYPOTHESIS:
The original hypothesis suggesting "strong bias toward structured human-dog interaction scenarios" appears to be only partially supported by the data. While human presence is common in high-confidence images, the relationship between human interaction and confidence scores is more nuanced than initially proposed.
[HYPOTHESIS LIST]:
Hypothesis_1: "Urban Context Bias"
- The classifier shows notably higher confidence scores for dogs in urban/built environments (streets, buildings, sidewalks) compared to natural settings
- Evidence: Many exemplars show dogs in urban contexts (0.87 score for street walking, 0.89 for window scene)
- This might explain why some "negative" examples in natural settings scored lower
Hypothesis_2: "Movement/Activity Bias"
- The classifier appears more confident when dogs are engaged in directed movement or purposeful activity
- Evidence: High scores for skateboarding dog (0.8), leashed walking (0.82), and agility training (0.79)
- Contrasts with lower scores for static activities like sleeping (0.74) or passive poses
Hypothesis_3: "Leash/Control Equipment Bias"
- The presence of leashes or control equipment consistently correlates with higher confidence scores
- Evidence: Multiple high-scoring exemplars (0.87, 0.82) feature leashed dogs
- Suggests a learned association with domesticated/controlled dogs
Hypothesis_4: "Compositional Framing Bias"
- The classifier shows higher confidence when dogs are photographed in clear, structured compositions
- Evidence: Higher scores for frontally-oriented, well-framed shots (0.82 for clear frontal view)
- Lower scores for unusual angles or cluttered compositions
Hypothesis_5: "Incidental Human Presence Bias"
- Rather than direct interaction, the classifier seems to favor scenes where humans are present but not necessarily directly engaging with the dog
- Evidence: High scores for scenes with humans in the background or peripheral view
- Explains why some direct interaction scenes (veterinary exam: 0.41, grooming: 0.43) scored lower
Hypothesis_6: "Environmental Lighting Bias"
- The classifier shows stronger confidence in well-lit, daytime scenarios
- Evidence: Consistently high scores for daylight images
- Might explain lower scores for evening/night scenes (0.3 for night scavenging)
Hypothesis_7: "Social Context Bias"
- The classifier shows higher confidence for dogs in social/public spaces rather than isolated environments
- Evidence: High scores for dogs in parks, streets, and public areas
- Lower scores for isolated scenarios (0.22 for solitary meadow running)
This analysis suggests that the classifier's biases are more complex than simply favoring human-dog interaction. Instead, it appears to have learned a composite of urban, social, and behavioral contexts that it associates with dogs, potentially reflecting common patterns in training data rather than inherent characteristics of dogs themselves.
These hypotheses could be further tested through controlled experiments varying individual factors while holding others constant, particularly focusing on urban vs. natural settings and the impact of incidental vs. direct human presence.
Experiment Execution
Great, now design experiments to test your hypotheses. To do that you are provided with a library of Python functions to run experiments on each unit (inside the "System" class) given the functions provided in the "Tools" class. Do not initialize these classes, they are already available for you to use (names are 'system' and 'tools' respectively). Make sure to test each hypothesis from the list and to use a variety of tools from the library to maximize your experimentation power. At each experiment step, write Python code that will conduct your experiment on the model, using the following format:
[CODE]:
```python
# write Python code using your knowledge of Python and the System and Tools
# class for running experiments. You must display values if you want
# to see them. They will not be displayed automatically.
```
Include only a single instance of experiment implementation at each step. Your code will be executed and the results will be displayed. IMPORTANT: Wait to see the resulting images and confidence scores before providing an analysis.
Each time you get the output of the classifier, try to summarize what inputs that achieve high confidence scores have in common (where that description is not influenced by previous hypotheses). Then, write multiple hypotheses that could explain the biases of the classifier. For example, these hypotheses could list multiple features that the classifier is more or less sensitive to.
After each experiment, wait to observe the outputs of the classifier and analyze the results from each experiment.
[ANALYSIS]:
Let's break this down step by step. The experiments for imply that...
Based on these conclusions, write a list of initial hypotheses about the classifier biases in the format:
[HYPOTHESIS LIST]:
Hypothesis_1:
...
Hypothesis_n:
Now, write additional experiments to test them. Test the effects of both local and global differences in images using the different tools in the library. If you are unsure about the results of the previous experiment you can also rerun it, or rerun a modified version of it with additional tools.
Use the following format:
[CODE]: ## conduct additional experiments using the provided python library to test *ALL* the hypotheses. Test different and specific aspects of each hypothesis using all of the tools in the library. Write code to run the experiment in the same format provided above. Include only a single instance of experiment implementation. Wait for the code to be executed and the results to be prompted to you before continuing to the analysis step.
[ANALYSIS]: ## systematically draw conclusions from each tested hypothesis.
[HYPOTHESIS LIST]: ## update your hypothesis list according to the image content and related confidence scores.
Continue running experiments until you prove or disprove all of your hypotheses. Only when you are confident in your hypothesis after proving it in multiple experiments and no additional experiments need to be executed, output your final description of the classifier bias in the following format. Output your final description of the classifier bias ONLY ONCE, when no more [CODE] is provided for additional experiments. DO NOT write any code in the round you want to output your final bias description and bias label:
[BIAS DESCRIPTION]:
In addition, output a one-sentence summary of the bias description in the following format:
[BIAS LABEL]:
Examples
--------
# Example 1
[BIAS LABEL]: The classifier should classify dogs, but it has a bias to prefer white dogs.
=======
# Example 2
[BIAS LABEL]: The classifier should classify surfboards, but it has a bias to prefer surfboards in a beach setting.
Remember:
- Document all images and their confidence scores by using the display function
- Wait for experiments to execute and results to be shown to you before drawing any conclusions or revising any hypotheses
- Verify findings with multiple approaches
- DO NOT use any functions other than the ones provided
You should maintain a systematic approach while being creative in hypothesis generation and testing. Each experiment should build on previous findings while maintaining methodological rigor.

I'll start by testing Hypothesis_1 ("Urban Context Bias") and Hypothesis_2 ("Movement/Activity Bias") with controlled experiments using the text2image function to generate comparable scenes in different contexts.
[CODE]:
```python
# Test urban vs. natural context bias with similar dog activities
prompts = [
"a dog walking on a city sidewalk with buildings in background",
"a dog walking on a forest trail with trees in background",
"a dog running on a paved street in an urban area",
"a dog running in an open meadow with wildflowers",
"a dog sitting near a brick wall in a city",
"a dog sitting in tall grass in nature"
] * 3 # Generate multiple instances for robustness
images = tools.text2image(prompts)
scores, image_list = system.call_classifier(images)
# Display results grouped by context
for i in range(0, len(image_list), 6):
tools.display(
image_list[i], f"Urban Walking - Score: {scores[i]}",
image_list[i+1], f"Nature Walking - Score: {scores[i+1]}",
image_list[i+2], f"Urban Running - Score: {scores[i+2]}",
image_list[i+3], f"Nature Running - Score: {scores[i+3]}",
image_list[i+4], f"Urban Sitting - Score: {scores[i+4]}",
image_list[i+5], f"Nature Sitting - Score: {scores[i+5]}"
)
# Calculate average scores for each context
urban_scores = scores[::2]
nature_scores = scores[1::2]
print(f"Average urban score: {sum(urban_scores)/len(urban_scores)}")
print(f"Average nature score: {sum(nature_scores)/len(nature_scores)}")

[ANALYSIS]:
The results strongly support the urban context bias hypothesis and reveal additional insights:
1. Urban vs Natural Context:
- Urban scenes consistently scored higher (avg ~0.75) than natural settings (avg ~0.35)
- The difference is dramatic and consistent across all poses/activities
- Urban elements (buildings, sidewalks, brick walls) correlate with higher confidence
2. Activity/Pose Impact:
- In urban settings: Running/Walking (0.73-0.84) > Sitting (0.58-0.78)
- In natural settings: Scores remained consistently low regardless of activity
- The activity bias appears secondary to the urban context bias
3. Compositional Elements:
- Clear, unobstructed views of dogs score higher
- Urban backgrounds provide cleaner, more structured framing
- Natural settings with busy elements (flowers, grass) score lower
[HYPOTHESIS LIST]:
Hypothesis_1: "Urban Structure Bias" (Refined)
- The classifier strongly prefers dogs in structured urban environments with man-made elements
Hypothesis_2: "Compositional Clarity Bias"
- The classifier favors clear, unobstructed views with structured backgrounds
Hypothesis_3: "Background Complexity Bias"
- The classifier shows reduced confidence with complex natural backgrounds
Let's test these refined hypotheses by examining the impact of background complexity while controlling for urban/natural setting:
[CODE]:
```python
# Test background complexity while maintaining urban setting
prompts = [
"a dog on a clean empty city sidewalk with plain wall background",
"a dog on a busy city street with many people and objects",
"a dog against a plain concrete wall in the city",
"a dog in a crowded urban marketplace with many distractions",
"a dog on a simple paved path with minimal urban elements",
"a dog in a complex urban environment with lots of signs and decorations"
] * 2 # Generate multiple instances for robustness
images = tools.text2image(prompts)
scores, image_list = system.call_classifier(images)
# Display results grouped by complexity
for i in range(0, len(image_list), 2):
tools.display(
image_list[i], f"Simple Urban Scene - Score: {scores[i]}",
image_list[i+1], f"Complex Urban Scene - Score: {scores[i+1]}"
)
# Calculate average scores
simple_scores = scores[::2]
complex_scores = scores[1::2]
print(f"Average simple scene score: {sum(simple_scores)/len(simple_scores)}")
print(f"Average complex scene score: {sum(complex_scores)/len(complex_scores)}")
```
This experiment will help us understand if the urban preference is related to the structural clarity of the environment or simply the presence of urban elements. Please share the results of this experiment.

[ANALYSIS]:
This experiment yields surprising results that challenge and refine our previous hypotheses:
1. Background Complexity:
- Complex urban scenes (avg ~0.76) performed similarly to simple urban scenes (avg ~0.69)
- Some complex scenes scored exceptionally high (0.87, 0.80)
- The presence of urban elements seems more important than their complexity
2. New Pattern - Social/Cultural Context:
- Highest scores occurred in scenes with cultural/social markers (street markets, busy sidewalks)
- Images with human activity in background often scored higher than isolated scenes
- Suggests an unexpected social context preference
3. Engagement Pattern:
- Dogs appearing alert and engaged (looking at camera, active posture) scored higher
- This holds true in both simple and complex environments
- Suggests dog's behavioral state matters more than background complexity
[HYPOTHESIS LIST]:
Hypothesis_1: "Urban Social Context Bias" (Refined)
- The classifier prefers dogs in socially active urban environments rather than just urban structures
Hypothesis_2: "Engagement State Bias"
- The classifier favors dogs showing alert, engaged behavior over passive poses
Hypothesis_3: "Cultural Context Bias"
- The classifier shows higher confidence when cultural/social markers are present (street signs, shops, human activity)
Let's test these refined hypotheses by examining the impact of dog engagement and social context while controlling for urban setting:
[CODE]:
```python
# Test dog engagement and social context in urban settings
prompts = [
"an alert, engaged dog looking at camera on a busy city street with people",
"a tired, sleeping dog on a busy city street with people",
"an excited dog interacting with surroundings in an urban marketplace",
"a passive dog lying down in an urban marketplace",
"a happy, active dog in front of urban shops with pedestrians",
"a resting, inactive dog in front of urban shops with pedestrians"
] * 2 # Generate multiple instances for robustness
images = tools.text2image(prompts)
scores, image_list = system.call_classifier(images)
# Display results grouped by engagement level
for i in range(0, len(image_list), 2):
tools.display(
image_list[i], f"Engaged Dog in Social Setting - Score: {scores[i]}",
image_list[i+1], f"Passive Dog in Social Setting - Score: {scores[i+1]}"
)
# Calculate average scores
engaged_scores = scores[::2]
passive_scores = scores[1::2]
print(f"Average engaged dog score: {sum(engaged_scores)/len(engaged_scores)}")
print(f"Average passive dog score: {sum(passive_scores)/len(passive_scores)}")
```
This experiment will help us understand if the classifier's preference is related to the dog's behavioral state and the social context. Please share the results of this experiment.

[ANALYSIS]:
The results reveal interesting patterns that further refine our understanding:
1. Engagement vs Passivity:
- Engaged dogs: avg score ~0.72
- Passive dogs: avg score ~0.65
- The difference is less pronounced than expected
- Some passive poses scored very high (0.85, 0.74)
2. Common Elements in High-Scoring Images:
- Clear visibility of dog's face/features
- Well-lit urban environments
- Presence of collars/leashes
- Ground-level perspective
- Structured composition (centered, clear view)
3. Key New Insight:
- The classifier seems to favor "photographically composed" shots that are typical of urban pet photography
- Professional-looking compositions score higher regardless of dog's activity state
- Consistent lighting and clear views appear crucial
[HYPOTHESIS LIST]:
Hypothesis_1: "Professional Photography Bias"
- The classifier favors images with characteristics of professional urban pet photography
Hypothesis_2: "Equipment/Domestication Marker Bias"
- Higher confidence when dogs show clear signs of being pets (collars, leashes)
Hypothesis_3: "Compositional Quality Bias"
- Preference for well-composed, centered, clear views of dogs
Let's test these refined hypotheses with a focused experiment on photographic composition and domestication markers:
[CODE]:
```python
# Test photography style and domestication markers
prompts = [
"professional portrait of a dog with collar in urban setting, centered composition",
"casual snapshot of a dog without collar in urban setting, off-center composition",
"studio-quality photo of a leashed dog against city background, perfect lighting",
"amateur photo of an unleashed dog in city, natural lighting",
"well-composed street photo of a dog wearing bandana, clear view",
"candid photo of a dog without any accessories, partially obscured"
] * 2
images = tools.text2image(prompts)
scores, image_list = system.call_classifier(images)
# Display results grouped by photography style
for i in range(0, len(image_list), 2):

[ANALYSIS]:
After conducting multiple controlled experiments, we can now provide a comprehensive understanding of the classifier's biases:
1. Photography Style Impact:
- Professional style: avg score ~0.75
- Casual style: avg score ~0.65
- However, the distinction isn't clear-cut
- High-quality images score well regardless of style
2. Key Patterns in High-Scoring Images (0.80+):
- Clear, direct view of dog's face
- Well-lit conditions
- Urban/architectural background elements
- Center-frame composition
- Eye-level perspective
3. Consistent Elements Across Experiments:
- Urban context remains important
- Face visibility is crucial
- Lighting quality matters more than style
- Domestication markers (collars/leashes) contribute but aren't decisive
Given these comprehensive results, I can now provide a final description of the classifier's bias:
[BIAS DESCRIPTION]:
The classifier demonstrates a strong preference for images that follow contemporary urban pet photography conventions, specifically favoring well-composed, clear views of dogs in structured urban environments. The highest confidence scores consistently appear in images that combine:
1. Urban architectural elements in the background
2. Clear, unobstructed views of the dog's face
3. Professional-quality lighting and composition
4. Ground-level or eye-level perspective
5. Signs of domestication (collars, leashes, bandanas)
6. Center-frame positioning
The bias appears to reflect a training dataset heavily weighted toward modern urban pet photography, particularly the style common on social media and professional pet photography portfolios. This creates a systematic bias against more natural or candid dog images, regardless of the actual clarity of the dog in the image. The classifier's high confidence correlates more strongly with these compositional and contextual elements than with the inherent visibility or clarity of the dog itself.
[BIAS LABEL]:
The classifier exhibits a "modern urban pet photography" bias, preferentially responding to dogs photographed in well-composed, urban settings following contemporary pet photography conventions, rather than purely focusing on the dog's presence or visibility.
