(要約): 本論文は，粒子間の近傍距離を考慮するネットワーク構造型PSO(NS-PSO)を提案している．NS-PSOの全ての粒子は，トポロジー空間の近傍関係に従って，他の粒子と結合されている．また，NS-PSOはその結合関係を，粒子間の情報交換だけでなく，群の多様性にも用いる．粒子間のトポロジー空間内の近傍距離を粒子の更新に用いることで，群の多様性が向上するだけでなく，解が局所解に陥ることを避ける効果がある．通常のPSOと比較したシミュレーション結果から，提案手法であるNS-PSOは探索性能が向上していることを確認した．

M-Ary Modulation Scheme Based on Separation of Deterministic Chaotic Dynamics for Noncoherent Chaos-Based Communications,
Nonlinear Theory and Its Applications, IEICE, Vol.5, No.2, 210-221, 2014.

(要約): 本論文ではノンコヒーレントカオス通信システムのための，カオスダイナミクスの分離と再構成に基づく多値変調手法を提案する．多値変調方式とはbビットのデータをM(=2^b)個の独立した系列を用いて送信する手法である．M個の系列を生成するために，本研究ではM個のインターリーバとデインターリーバのペアを用意し，カオス系列の分離と再構成を行う．具体的には，送受信機間で複数のインターリーバとデインターリーバペアにbビットのデータを対応させる．送信機側では，送信データに対応したパターンを選び，それに従ってカオス系列の並び替え(分離)を行うことでデータの変調を行う．受信機側では，共有しているパターンに従って受信した信号の系列を元に戻す(再構成)．ここで，送信側で並べ替えられた系列を元に戻すデインターリーバは1種類しかないことに注意する．ゆえに，再構成された系列のカオスダイナミクスを解析し，元のカオス系列に戻すデインターリーバを選択する事で，そのデインターリーバに対応しているデータを復調データと判定できる．以上の提案した多値変調方式を本論文ではコンピュータシミュレーションにより評価する．

(要約): 本論文ではノンコヒーレントカオス通信システムでの利用を想定したカオスダイナミクスに基づく誤り訂正手法を提案する．今，同一のカオス写像から生成された2つの連続するカオス系列を考える．この時，2つ目のカオス系列の初期値は1つ目のカオス系列の最後の値に基づいて生成された値と仮定すると，この2つの系列は同一のカオスダイナミクスを持つ系列として見なす事ができる．この特徴は受信機側で正確にデータ復調するための付加情報として利用できると考え，これを本論文では誤り訂正に利用する．提案手法を用いてコンピュータシミュレーションを行った結果，誤り訂正無しの従来手法と比較して，提案手法では約1∼1.5dBの利得が得られた．

Journal of Signal Processing, Vol.13, No.2, 161-169, 2009.

(要約): 本論文ではノンコヒーレントカオス通信システムにおける，HaslerとSchiming らによって提案された最適受信機に注目する．この最適受信機は送信機側で用いられているカオス写像と受信信号系列との確率密度関数(PDF)を算出し，送信側で用いられたカオス写像を確率的に求める事でデータの復調を行う手法である．しかしながら，本手法はPDFの算出に高い計算処理能力が必要である事が知られている．ゆえに，最適受信機と異なるアルゴリズムを用いて，それと同等もしくは近い性能を有する準最適受信機の開発が重要であるとされている．そこで本論文では，PDFの計算を用いない新たな準最適受信機の提案を行う．具体的には，PDFの計算の代わりにカオス写像と受信信号系列との最短距離を計算する事で，距離が短い方のカオス写像を選択する事でデータの復調を行う．最短距離の計算というシンプルな手法を用いた事で，PDFよりも大幅に計算処理時間の短縮に成功した．また，復調性能も最適受信機と同等の性能を示した．

(要約): 本論文では，誤り近傍度を考慮するSOM(FN-SOM)を提案している．誤り近傍度はFN-SOMのニューロン間に存在し，近傍距離間の重みとして働く．この誤り近傍度を学習と共に変化させることで，``本当の近傍''と``誤った近傍''をリアルタイムで区別することが可能となり，入力の形状に対応したより柔軟な学習を可能とする．FN-SOMを様々な入力データに適用し，その振る舞いを調査，及び有効性を確認している．また，FN-SOMはネットワーク構造を変化させるのではなく，誤り近傍度という新たな指標を用い，それを学習と共に変化させることにより柔軟な学習を行うという手法であることから，RSOM法，DSOM法はでは困難であった一括学習にも対応でき，計算時間の大幅な短縮に成功している．さらに，学習と共に柔軟に変化する誤り近傍度を有効利用することで，FN-SOMによる新しいクラスタ視覚化方法への応用も提案している．

(要約): 本論文では，特徴の異なる二種類のSOMを同時に複数用いるアルゴリズム(nSOM法)を提案している．この二種類のSOMに異なる特徴をもたせることにより，入力空間全体に広がるデータと入力データが集中している部分とを別々に自己組織化することができることを確認している．この特徴を生かして，nSOM法をノイズを多く含んだデータのクラスタリングに応用し，シミュレーションによりクラスタ部分のみの抽出を可能とする．さらに，視覚的に確認できない5次元データに対してもシミュレーションを行い，正答率から，高次元入力データにおいてもnSOM法が有効であることを確認している．通常単体で用いるSOMを複数用い，さらに，シンプルなアルゴリズムであるにもかかわらず有効な結果を得られる本成果は，新規性，有効性の面からも評価できると考える．

(要約): 本論文では，多導体RLCG伝送線路のアドミタンス行列の極を解析的に求めるためのアルゴリズム，および受動性を満足する留数を求めるための手法を提案する．過渡応答に大きな影響を与える極をいくつか選択し，それらに対応する留数を求めることにより，アドミタンス行列の各要素を部分分数により近似することができる．ここで留数は，部分分数と正確なアドミタンス行列の周波数応答曲線が一致するように，最小二乗法を用いて計算される．この部分分数から伝送線路の漸近的等価回路を合成することができるため，既存の回路シミュレータを用いて容易に伝送線路を含む回路のシミュレーションを行うことが可能となる．数値実験により，線路長の短い伝送線路は低次の部分分数で近似することができ，効率良くシミュレーションが行えることが示される．

(要約): van der Pol発振器をインダクタで梯子状に結合した系において，隣接した発振器間の位相状態が同相同期から逆相同期，及び逆祖同期から同相同期へと連続して切り替わっていく現象を発見し，解析を行ってきた．この現象を位相反転波と呼び，位相反転波が複数本，同時に存在している状態を位相反転波動と呼んでいる．結合に用いるインダクタの大きさが全て同じである場合，位相反転波は，伝搬，端での反射，波同士の衝突による反射と消滅の 4種類の基本な挙動をするのみであるが，結合しているインダクタの大きさを途中で変えた場合，その境界で様々な現象を観測することができる．すなわち，N個の発振器を結合した系において， 1∼kとk∼Nを結合するインダクタを変えた回路を考え，この境界での位相反転波の挙動について観察を行い，現象の解析を行う． kまでの発振器を結合するインダクタとk以降の発振器を結合するインダクタの差が大きい場合，そこで位相反転波の反射が生じる．この反射のメカニズムはkまでを結合したインダクタよりk以降を結合したインダクタの大きさが非常に小さい場合と，非常に大きい場合では，反射のメカニズムが全く異なる．これらのことを明らかにし，メカニズムの解析を行う．さらに，回路実験を行い，コンピュータシミュレーションの結果と一致するか確認する．

(要約): ミキサ，変調器など通信分野における回路の多くは複数個の独立した周波数成分を持った信号源で駆動されている．もしこれらの信号源の周波数が極端に離れている場合，通常の数値積分手法では時間ステップを高い周波数成分のほうに設定しなければならず解析には大変多くの計算時間を要することとなる．ここではこれらの回路を効率よく解析するための周波数領域での緩和法と多次元フーリエ変換を用いた効率的なアルゴリズムを提案する．まずキャパシタやインダクタなどのリアクタンス成分は過渡現象の減衰成分とは無関係なので，回路を非線形抵抗部分回路とリアクタンス部分とに代用電源を用いて分割してから，それぞれの部分について定常応答が同じとなるように代用電源の値を求めていくものである．これらの手法はSPICEのDC,AC,過渡解析により実行されるため非常にシンプルで効率的なシミュレータとなっている．

周波数応答の近似を用いた伝送線路回路網の一解析手法,
電子情報通信学会論文誌(A), Vol.J82-A, No.1, 47-55, 1999年.

(要約): 伝送線路回路網の離散フーリエ変換に基づく方法では，考慮すべき周波数成分の数は回路網の有効周波数と入力電源が制限される時間に依存する．したがって，解析される回路網の有効周波数が同じ場合でも入力電源が長時間にわたる場合には，多くの周波数成分を必要とし演算効率が悪くなるという欠点をもつ．これは，各周波数での応答を求めるために回路方程式をそのたびごとに求解しなければならないことが原因である．本論文では，回路方程式の求解を最小限にとどめ，代わりに周波数応答を近似する方法を提案している．近似法としては，3次スプライン関数による方法と離散フーリエ変換·逆変換による方法を用いており，数値計算例を通して，比較的小規模な問題に対しては高速シミュレーション手法として知られているモーメント·マッチング法と比較して演算効率が優れていることが示されている．

(要約): N個の発振器を1つの抵抗で結合すると，結合抵抗に流れる電流を最小化しようとシステムが動作するため，N相同期現象が見られる．また，硬い発振器の結合系においてはN相同期だけでなく，N-1, N-2,..., 2相同期も見ることができ，より多くの位相状態を得ることができる．本研究では3次および5次非線形性を持つ発振器による，2種類の結合発振器ネットワークを提案する．一つは2次元蜂の巣状の構造を持っており，もう一つは格子状の構造を持っている．軟発振器によるシステムでは，蜂の巣状回路では3相同期現象に基づく位相パターンが，格子状回路では逆相同期に基づく位相パターンが得られる．また，硬発振器によるシステムではいずれの回路においても，3相および逆相同期に基づく位相パターンが得られ，さらにN相同期に基づかない位相パターンも見られる．提案ネットワークは隣り合う発振器のみが結合しており，初期状態に応じて多くの異なる位相パターンが見られるため，一種のセルラーニューラルネットワークとして利用できると考えられる．

(要約): 本論文では，抵抗で結合された簡単なカオス回路に発生する時空カオス現象が解析されている． 4個のカオス回路を結合した場合，計算機シミュレーションと回路実験により，カオスの準同期状態の位相差により特徴付けられる3種類の空間パターンが不規則に切り換わる現象が観測される．これは，大自由度非線形系にしばしば観測される空間パターンのカオス的遍歴現象と類似したものであり，すなわち，本研究の結果は，大規模システムで見られる時空カオス現象が，わずか4個の簡単な回路の結合系で観測されることを示したものであると言える．さらに，6個のカオス回路を結合した場合と二次元ネットワーク状に結合した場合についても計算機シミュレーションを行い，より複雑な時空カオス現象の発生を確認している．

Ant Colony Optimization Including Dull Ants Caused by Genetic Algorithm,
Journal of Signal Processing, Vol.16, No.4, 303-306, 2012.

(要約): We propose an ant colony optimization (ACO) including dull ants caused by genetic algorithm (GDACO). The GDACO algorithm combines ACO including dull ants with the genetic algorithm (GA). GDACO searches solutions using the pheromone of ACO and the genetic information of GA. In addition, GDACO consists of two kinds of ants: intelligent and dull. The dull ant is caused by mutation and cannot trail the pheromone. We apply GDACO to quadratic assignment problems (QAPs) and confirm that GDACO obtains more effective results than ACO and GA.

Data Extraction by Self-Organizing Map Containing Neurons with Additional States,
Journal of Signal Processing, Vol.10, No.4, 243-246, 2006.

(要約): A self-organizing map (SOM) is an unsupervised neural network introduced by Teuvo Kohonen. SOMs have attracted attention in studies of clustering in recent years. In this study, we propose SOM containing neurons with additional states. The basic algorithm of the proposed SOM is the same as that of the conventional SOM. However each neuron of the proposed SOM has an additional state value. The value decreases according to the update of the weight vectors. Furthermore, as the value decreases, the updated rate of the neurons is reduced. The behavior of the proposed SOM is investigated with an application to clustering input data including a lot of noise. We can see that the proposed SOM successfully extracts the cluster.

(要約): 本論文では，同じ周波数を持つN個のウィーンブリッジ発振器を1つの抵抗で結合したシステムを提案し，そこに見られる同期現象を調べている．本システムは，我々が過去に報告したLC発振器によるシステムとは異なる構造を持っているため，N相同期現象ではなく，3相または同相同期現象が見られる．本システムにおいても，初期状態を変化させることで，非常に多くの異なる安定な位相状態を得ることができる．特に，Nがそれほど大きくない場合，LC発振器によるシステムよりも多くの位相状態を得ることができる．本システムはインダクタを含んでおらず，また，外乱にも強いと考えられるため，LC発振器によるシステムと比べVLSIへの実装により適していると考えられる．

2種類の探索法を用いるミツバチコロニー最適化,
電子情報通信学会非線形問題研究会技術報告, Vol.112, No.6, 83-87, 2012年4月.

(要約): これまでの研究で,我々は群知能の一種であるミツバチの採餌行動をモデル化した新しいミツバチコロニー最適化(Bee Colony Optimization: BCO)として,役割分担を行うミツバチコロニー最適化(Bee Colony Optimization with Roleand Responsibility: BCORR)を提案した.BCORRは,グローバルサーチを行う探索バチとローカルサーチを行う派遣バチという様に現実のミツバチと同様に役割分担を行う.本研究では,我々はローカルサーチとグローバルサーチを並列に行う新しいBCORRを提案する.また,新しいBCORRではグローバルサーチ時の巨大近傍使用,ローカルサーチを行う位置の決定法をそれぞれ提案し,その振る舞いの調査を行う.そしてBCORRを巡回セールスマン問題(Traveling Salesman Problem: TSP)に適応し,従来のBCOより効果的な結果を得ることを確認する.

カンターレット変換とパルス結合ニューラルネットワークを用いた可視光画像と赤外線画像の合成法の提案,
電子情報通信学会非線形問題研究会技術報告, Vol.112, No.6, 31-34, 2012年4月.

(要約): 可視光画像と赤外線画像の合成は,それぞれの画像が持った特徴から非常に重要な情報を得ることができる.現在まで,様々な画像合成法が提案されている.特に,パルス結合ニューラルネットワークは画像のエッジに対して強く反応することから,その有用性が指摘されている.本研究では,非サブサンプルドカンターレット変換を用いて2種類の画像を係数に分解し,各係数ごとに合成を行う.分解された画像係数は,ラプラシアンフィルタと平均化フィルタの二種類のフィルタにかけららた後,パルス結合ニューラルネットワークによって合成される.提案する画像合成法を用いることによって,パルス結合ニューラルネットワークのみで画像合成を行った場合より優れた画像が得られることを示す.
