| ## About | ||
|
|
||
| Provides methods for performing mathematical operations over _tensors_ represented as spans. These methods are accelerated to use SIMD (Single instruction, multiple data) operations supported by the CPU where available. | ||
|
|
||
| ## Key Features | ||
|
|
||
| * Numerical operations on tensors represented as `ReadOnlySpan<float>` | ||
| * Element-wise arithmetic: Add, Subtract, Multiply, Divide, Exp, Log, Cosh, Tanh, etc. | ||
| * Tensor arithmetic: CosineSimilarity, Distance, Dot, Normalize, Softmax, Sigmoid, etc. | ||
|
|
||
| ## How to Use | ||
|
|
||
| ```C# | ||
| using System.Numerics.Tensors; | ||
|
|
||
| var movies = new[] { | ||
| new { Title="The Lion King", Embedding= new [] { 0.10022575f, -0.23998135f } }, | ||
| new { Title="Inception", Embedding= new [] { 0.10327095f, 0.2563685f } }, | ||
| new { Title="Toy Story", Embedding= new [] { 0.095857024f, -0.201278f } }, | ||
| new { Title="Pulp Function", Embedding= new [] { 0.106827796f, 0.21676421f } }, | ||
| new { Title="Shrek", Embedding= new [] { 0.09568083f, -0.21177962f } } | ||
| }; | ||
| var queryEmbedding = new[] { 0.12217915f, -0.034832448f }; | ||
|
|
||
| var top3MoviesTensorPrimitives = | ||
| movies | ||
| .Select(movie => | ||
| ( | ||
| movie.Title, | ||
| Similarity: TensorPrimitives.CosineSimilarity(queryEmbedding, movie.Embedding) | ||
| )) | ||
| .OrderByDescending(movies => movies.Similarity) | ||
| .Take(3); | ||
|
|
||
| foreach (var movie in top3MoviesTensorPrimitives) | ||
| { | ||
| Console.WriteLine(movie); | ||
| } | ||
| ``` | ||
|
|
||
| ## Main Types | ||
|
|
||
| The main types provided by this library are: | ||
|
|
||
| * `System.Numerics.Tensors.TensorPrimitives` | ||
|
|
||
| ## Additional Documentation | ||
|
|
||
| * [API documentation](https://learn.microsoft.com/en-us/dotnet/api/system.numerics.tensors) | ||
|
|
||
| ## Feedback & Contributing | ||
