This post will introduce the modern CSS layout modes, including flexbox, multi-columns, and grid.

Sharp tools make good work.

Codec Codec, short for compressor-decompressor, is an algorithm designed for compressing and decompressing video and audio data. Simply put, it’s an encoding and decoding algorithm. Why encoding? raw data can be very large and noisy encoding makes it easy to transmit and storage data Why decoding? preview or playback Video Codec H.264/AVC (MPEG-4 part 10/Advanced Video Coding) is the most widely used video codec on the market VP8, free and

The goal of machine learning is to find the best parameters. To train the model, we must start from some values. So, what do the initial parameters look like? Can we set all of them to the same value? Or we assign random values to the weights? In this post, we will talk about another important aspect of learning — weight initialization.

In the previous post, we introduced how to initialize weights. However, weights can be very large or small (great variance in weights). For larger weights, a tiny change in data will lead to large variance. For smaller weights, it has little influence on the model, which can be totally discarded.
