Jev Plays Tetris

The author had Jev play Tetris and described it as a practical, flexible general-purpose classifier. The API response took about 250 ms in Tokyo, which the author called nearly real time.

@typesafeai のJevにテトリスをさせてみました。API返答は東京で250msぐらい、ほぼリアルタイム。 渡した事実を読み違えないのと、confidence がちゃんと機能するのが印象的でした。柔軟で汎用的な分類器としてかなり実用的です。 マルチモーダルなど発展の余地が大きそうです。楽しみ! https://t.co/3tZC6PuS91
