From Hirakata-city, Osaka-prefecture, Japan

On this day(March 9th), I happened to take annual leave, and then my wife wanted to go, so we suddenly decided to go to Tsuruhashi Korean Town for lunch. This is officially called Ikuno Korea Town in Osaka , and the last time I went there was in June 2003 , so it's been 20 years since then. Last time I walked from Momodani station, but this time I decided to go from Tsuruhashi station in front of me. This has changed a lot in 20 years, and there are some shops with BTS pictures before entering Koreatown, and even though it is still around 10 o'clock, a group of young women are already walking down the street. From here, Koreatown is finally here. Right after entering the street is today's lunch shop. It was too early, so there weren't many shops or customers, but by the time we finished eating (11:00), the number of people had increased considerably. We were planning to have lunch at this restaurant, but we stopped because it was written on the internet that Tuesday was

I went to the Kunizakai ski resort on February 21st last month. At this time, Osaka was still in a state of emergency and I was wondering if I should go, but the number of infected people has decreased considerably and the ski resort is an outdoor activity and it is relatively safe compared to others. I decided to go for it. On this day, it was cold a few days ago, and there were more than 1m of snow, and it was warm with good weather and the temperature was quite warm, so it was just like spring skiing. Since it was open at 8 o'clock, I left around 5:30 and arrived at 7:55, but the first parking lot was already full and I was guided to the second parking lot, which was a little far away. The lift ticket office and ski rental area are also crowded, and we have to line up for more than 40 minutes for ski rental (in our case, only children's boots are rented). It was really vacant in February last year due to the influence of the corona, but this time it was more crowded than exp

Recently, I've been studying AI and machine learning using Python, and it's quite interesting to start doing it. Especially, I think it's really convenient that you can easily use TensorFlow and Keras with just a browser using Google Colaboratory. At first, I'm a little confused about where to start this kind of study, but there are many books on AI and machine learning, and when I read them at a bookstore and somehow keep in mind the keywords, I somehow understand the image. After that, if you make an online reservation for a book that seems good from the library and read it, your understanding will gradually deepen. It was a book called "Deep Learning Mechanism to Learn While Working with TensorFlow and Keras" that was very interesting to me and deepened my understanding of machine learning. As a result, I was able to grasp the concept of logistic regression, softmax function, sigmoid function, ReLU, convolutional filter, CNN, etc. in addition to matrix calc

With the third wave of corona coming, I checked what the current situation is. Domestic situation

This isn't new, but sometimes my head gets full and my head doesn't spin. I wondered why this happened and if there was a way to avoid it, and I repeated various thoughts and mistakes, but it seems that the cause and remedy have been understood, so I would like to write it. 1. A case where your head is full Experience shows the following as cases. Case1) In most cases, there are too many things to do, and in most cases it is difficult to know what to start with. If there are few todos, there is not much problem, but if there are many todos, the work list itself in my head becomes unclear, and the act of trying to remember it becomes a burden on my head.  Case2) When an unexpected difficult problem comes up. I can afford to think slowly, especially when there is no load, but this kind of story usually occurs when I'm busy, which puts a lot of strain on my brain and makes me exhausted. Case3) When things don't go as you want. A common example of this is when you entrust a

We went to M akino sunny beach Chinaihama auto campsite (Sep 26-27 2020). This was a campsite I've always wanted to visit, so I was really looking forward to it. The weather forecast was delicate on this day, but the weather forecast improved and I couldn't find a day to go if I missed this day, so I was tough, but after all, it was midnight and the thunder became quite severe. I thought this was dangerous and we were decided to evacuate to the car on the way. Day 2:
