如果不确定用哪个激活函数，隐藏层可以先用 ReLU，输出层按任务选择；训练中注意梯度情况，如果梯度消失或爆炸，再考虑替换或调整激活函数。

Super Bowl LX was a two-score game with less than five minutes remaining. New England had the ball on the Seahawks’ 44-yard line and – after reaching the end zone in the fourth quarter, finally – that familiar sense of possibility. But that quickly vaporized when Devon Witherspoon knifed in on a corner blitz and jarred the ball loose from the Patriots quarterback, Drake Maye, mid-throw. Uchenna Nwosu snatched it in stride and rumbled 45 yards to the end zone, sealing Seattle’s 29‑13 victory.
While it didn’t make the cut, the Instax Square SQ1 is also worth a brief mention. Like the Mini 12, the Square SQ1 produces good-quality shots, is easy to set up and use, and features a built-in selfie mirror. The reason we didn’t include it above, however, is that it costs nearly twice as much as the Mini 12 at $159.95, though we do sometimes see it on sale for $100. That said, it might be worth a look if you prefer large 2.4 x 2.4-inch square prints and relatively true-to-life photos over vintage-looking stills. After all, the SQ1 is still cheaper than the Polaroid Flip and produces higher-quality images than the Kodak Mini Shot 3 Square Retro, which also prints similarly sized square shots.
