Class GSM8KBenchmark<T>

Namespace
AiDotNet.Reasoning.Benchmarks
Assembly
AiDotNet.dll

Grade School Math 8K (GSM8K) benchmark for evaluating mathematical reasoning.

public class GSM8KBenchmark<T> : IBenchmark<T>

Type Parameters

T

The numeric type used for scoring (e.g., double, float).

Inheritance
GSM8KBenchmark<T>
Implements
Inherited Members

Remarks

For Beginners: GSM8K is a dataset of 8,500 grade school math word problems. These are the kinds of problems you'd see in elementary school math:

Example problems:

  • "Janet has 15 apples. She gives 40% to her friend. How many does she have left?"
  • "A train travels 60 mph for 2.5 hours. How far does it go?"
  • "If 3 pizzas cost $45, how much does 1 pizza cost?"

Why it's important:

  • Tests basic mathematical reasoning
  • Requires understanding word problems
  • Needs step-by-step calculation
  • Benchmark for many reasoning models

Performance levels:

  • Human performance: ~90-95%
  • GPT-3.5: ~57%
  • GPT-4: ~92%
  • ChatGPT o1: ~95%
  • DeepSeek-R1: ~97%

Constructors

GSM8KBenchmark()

Initializes a new instance of the GSM8KBenchmark<T> class.

public GSM8KBenchmark()

Properties

BenchmarkName

Gets the name of this benchmark.

public string BenchmarkName { get; }

Property Value

string

Description

Gets a description of what this benchmark measures.

public string Description { get; }

Property Value

string

TotalProblems

Gets the total number of problems in this benchmark.

public int TotalProblems { get; }

Property Value

int

Methods

EvaluateAsync(Func<string, Task<string>>, int?, CancellationToken)

Evaluates a reasoning strategy on this benchmark.

public Task<BenchmarkResult<T>> EvaluateAsync(Func<string, Task<string>> evaluateFunction, int? sampleSize = null, CancellationToken cancellationToken = default)

Parameters

evaluateFunction Func<string, Task<string>>

Function that takes a problem and returns an answer.

sampleSize int?

Number of problems to evaluate (null for all).

cancellationToken CancellationToken

Cancellation token.

Returns

Task<BenchmarkResult<T>>

Benchmark results with accuracy and detailed metrics.

Remarks

For Beginners: This runs the benchmark by: 1. Selecting problems (either all or a random sample) 2. Asking the reasoning system to solve each one 3. Comparing answers to the correct solutions 4. Calculating accuracy and other metrics

The evaluateFunction is your reasoning system - it takes a problem string and returns an answer string.

LoadProblemsAsync(int?)

Loads benchmark problems (for inspection or custom evaluation).

public Task<List<BenchmarkProblem>> LoadProblemsAsync(int? count = null)

Parameters

count int?

Number of problems to load (null for all).

Returns

Task<List<BenchmarkProblem>>

List of benchmark problems.

Remarks

For Beginners: Returns the actual problems and their correct answers so you can inspect them or run custom evaluations.
