Types ¶
type FileAdapter ¶
type FileAdapter struct {
Path string
}
FileAdapter is a neural net param store implementation that uses the filesystem, its main purpose is to facilitate testing. Given its low performance it is strongly discouraged for production use
func NewFileAdapter ¶
func NewFileAdapter(conf map[string]interface{}) (*FileAdapter, error)
NewFileAdapter returns an initialized file net param store object
func (FileAdapter) Delete ¶
func (fa FileAdapter) Delete(id string) error
Delete can be used to delete the state of a specific neural net from a file on disk
type MLPParams ¶
type MLPParams struct {
Accuracy float32
ActivationFunc string
Averages map[string]float32
Deviations map[string]float32
Epoch int
ErrMargin float32
Inputs []string
LearningRate float32
Topology []int
Outputs []string
Weights [][]float32
}
MLPParams holds the minimum information required to rebuild the net from scratch plus some metadata that is required for other parts of the system
func (MLPParams) Brief ¶
Brief returns a standard summarized version of the net's params (not enough to rebuild it but enough to compare it)
type NetParamStore ¶
type NetParamStore interface {
Delete(id string) error
// Returns an array of net IDs matching a glob pattern, use * to retrieve all
List(offset, limit int, pattern string) ([]string, int, error)
// Load retrieves the NetParams for a net from a store, will return true and a nil error if found
Load(id string, np NetParams) (bool, error)
Save(id string, np NetParams) error
}
NetParamStore is an abstraction over the storage service that will be used to share the nets between instances, it should allow queries by ID and be fairly performant (Redis is a good option here but it's good to have flexibility)
type NetParams ¶
type NetParams interface {
Brief() *types.BriefNet
Marshal() ([]byte, error)
Unmarshal(b []byte) error
}
NetParams serves to ensure that any new net implementation will come with instructions for writing and reading it to and from the store as well as a way to get a standard representation of it that the API can use
type RedisAdapter ¶
type RedisAdapter struct {
// contains filtered or unexported fields
}
RedisAdapter is the neural net param store implementation for Redis
func NewRedisAdapter ¶
func NewRedisAdapter(conf map[string]interface{}) (*RedisAdapter, error)
NewRedisAdapter returns an initialized Redis param store object
func (*RedisAdapter) Delete ¶
func (ra *RedisAdapter) Delete(id string) error
Delete can be used to delete the state of a specific neural net from Redis
func (*RedisAdapter) List ¶
List can be used to page through the IDs of the nets that are stored in Redis by starting with offset 0 and then continuing to call the method with the updated cursor value it returns until it becomes 0
