When

TypeScript

when lets you declaratively gate side-effects, computations, or constant values behind one or more conditions (booleans or predicates). If all conditions are truthy, your callback runs (or your constant is returned). Otherwise it returns false.

type Condition<Args extends unknown[]> = boolean | ((...args: Args) => boolean);
type Nested<T> = T | ReadonlyArray<Nested<T>>;

export const when =

Converting samples before import to JoMoX Alpha Base

Samples need to be 16 bit / 48kHz mono wav files.

Requirements:

Zsh (run zsh --version to check if it's installed already)
FFmpeg (brew install ffmpeg)

This guide is for UNIX (MacOS or Linux) users, the process would be similar on Windows machines with FFmpeg though. The required FFmpeg options are:

ffmpeg -i $INPUT -acodec pcm_s16le -ac 1 -ar 48000 $OUTPUT

Dokku ACL plugin

Retrain a MobileNet model and use it in the browser with TensorFlow.js

DRAFT

Combining TensorFlow for Poets and TensorFlow.js.
Retrain a MobileNet V1 or V2 model on your own dataset using the CPU only.
I'm using a MacBook Pro without Nvidia GPU.

MobileNets can be used for image classification. This guide shows the steps I took to retrain a MobileNet on a custom dataset, and how to convert and use the retrained model in the browser using TensorFlow.js. The total time to set up, retrain the model and use it in the browser can take less than 30 minutes (depending on the size of your dataset).

Example app - HTML/JS and a retrained MobileNet V1/V2 model.
