+# python\_challenge
+python\_challengeの実装です.  
+
+## Introduction
+###名前
+下垣内 隆太  
+
+###大学名
+東京大学  
+
+###専攻
+工学部電子情報工学科  
+
+### 今までの開発経験
+あまりgithubには上げていませんが[自分のアカウント](https://github.com/rysmarie?tab=repositories)を見てください.  
+高専に在籍していたときの卒研で作成したプログラムが[このリポジトリ](https://github.com/kcct-fujimotolab/3DCNN)に上がっています.  
+ディープラーニングのライブラリ・フレームワークはTensorFlow, Chainer, Kerasを使ったことがあります.  
+
+### 中間的な目標
+インターンシップに参加し, 自分がどの程度できるのかを確かめることが現段階での目標です.
+また, 論文をもっと読み実装することも目標としており, 確率統計や英語の勉強をしています.
